Django Web App Development on the Raspberry Pi

So what is Django well Django is a web development framework that saves you time and makes web development a joy using Django. You can build and maintain high-quality web applications with minimal fuss, and we are all going to do that on the Raspberry Pi.

The Raspberry Pi is a tiny computer with enough power to run a Django development server. So here we’re going to attempt installing and deploying our first Django project on the Raspberry Pi and maybe develop a web application on later articles. You may be asking why don’t we just build a web application from scratch without a framework? Well, there will come a time when your application would be needing to connect to a database, and you would end up duplicating your database connection code to other parts of your application.

The practical way is to refactor it into a reusable function. Another problem you’ll encounter is you have to remember to close your database every time and you will end up with a lot of boilerplate code that is prone to mistakes. Your application may not be reusable in a different environment because of some environments, specific configuration. And lastly, if a web designer, who has no experience in coding, wants to redesign the page, he or she might crash the application, because, ideally the logic of the page or the retrieval of information from the database would be separate from the presentation which is the HTML Display of the page, these problems are precisely what a web framework intends to solve.

I’r sure some of you are already familiar with the MVC design pattern or Model View controller design pattern for beginners MVC, like what I mentioned earlier, is a django architecture that separates the logic, the model and the controller from the presentation. The view in django it’s more like an mtv or model template view design pattern. Don’t worry about that now, we’ll get more into that later.

In the meantime, let’s go ahead and install django on the raspberry pi. Okay, so I have here a freshly installed raspbian, which is the official operating system of the raspberry pi. What we’re going to do here is to open up a terminal and install virtual ends, which stands for a virtual environment. To put it simply, virtual environment is an isolated working copy of Python, which allows you to work on a specific project without worry of affecting other projects.

So let’s go ahead and install virtual end, but before we do that, let’s update our package lists by typing sudo. Apt-Get update and when it’s done updating we can go ahead and type in sudo, apt-get install virtual end hit enter, and in my computer, my or my raspberry pi, it’s already been installed. Now that we have our virtual environment installed. We can now create our virtual environment directory that we are going to use for our project to do that.

We just type virtual end dot. Then P, slash user, slash bin, slash Python 3. What this code does is. It makes a hidden directory called vent because in Linux beginning your directory name with the dot, makes that directory hidden and the dash B is an option. You pass virtual environment on what version of Python you want to use. In this case, we want to use Python 3 inside slash user USR, slash bin now hit enter, and when it’s done, if you type LS la you would see that it created our project directory as expected to use it.

We just type source that Ven slash bin. Slash activate you will see our prompt has changed, indicating that we are now in our isolated Python environment. We just type the activate to go back to our regular, prompt and escape our isolated Python environment. We can now install django. There are other ways to install django, but for simplicity, we’ll use pip to install the latest version of django available from PI P or the Python package index repository to do that.

We just type pip, install django and hit enter to test Jiang, the Django installation. You just start up a Python, interactive interpreter by typing Python, and if the installation was successful, we should be able to import Django and check its version. Okay. Moving on, we can now take our first step into creating our first project. A project is a collection of settings for an instance of Django, including database configuration Django, specific options and application specific settings.

So let’s exit our Python shell and type sy, Django admin, the PI or just Django admin, start project. Then the name of our project, which we’ll just name my site for now then hit enter okay. So it says that my site directory already exists just going to delete, delete it for now and make another one. So I’m just going to repeat the command Django admin that I start project my site and then hit enter.

What the start project command does is it creates a directory containing six files? Okay, there we are my site, which is the outer. My site directory is just a container for our project. It name doesn’t matter to Jango, you can rename it to anything. You like manage that PI py is a command line utility that lets you interact with this Jango project in various ways. Type Python manage that hi-oh. We just have to change into the directory first and type Python manage that py help to get a feel for what it can do.

Okay, so here are your options now you should never have to edit this file. It’s created in this directory purely for convenience. Okay, so let’s go back to files that were created. Oh now, it has added a few more files, but we’ll just go over on the basic files that we are concerned about. The next is the inner my site directory. It is the actual Python package for your project and we have our ini’ that py, it’s an empty file required for python to treat the my site directory as a package example a group of python modules – and we also have our settings that pi, which is the Settings configuration for this Django project take a look at it to get an idea of the types of settings available along with their default values.

Okay, so we’ll just skip that for now and we have our URL stat pot, the URLs that PI for this Django project is the table of contents of your jungle powered site. Next. Is we have our WSGI pi an entry point for WSGI compatible web servers to serve your project? And lastly, we have Ras GI that pipe as well as WSGI Jango also supports deploying on a SGI which is the emerging python standard for a synchronous, web servers and applications.

Now to see our barebone application in action. Let’s run the server by changing into the directory of our project, CD, my site and type the command that slash manage, that pi run server the run server launches the built-in django development server, which is a lightweight web server that we can use while developing our site. We will receive a warning message in red telling us we have unapplied migrations welljust.

We will just ignore that for now. Okay, now, if we open up our browser and go to HTTP colon, slash slash 127.0.0.1 colin 8000, which is the IP address that stands for home on port 8000 and if everything goes well, then we’ll see that it works by default. The run server command starts the development server on port 8000, listening only for local connections. If you want to change the server sport, pass it a command-line argument like so so, let’s just ctrl C and run our command again run server and we want to run it on port 8080.

So that’s how you change the port? Ok! So now we will access it here on port 8080. If you want other computers on your local network to be able to view your Django site by visiting your IP address in their web browsers, then you type manage that slash manage that pie run server. 0.0.0.0. 8000. Well, that’s all we have for now in this tutorial. If you have any questions or comments, please post it in the comment section below down below and I’ll do my best to answer them.

lb: Blog System in Less Than 100 Lines of Shell Script!

So especially now that I’m starting my dissertation and I’m going to be like I’m basically going to be a neat like I don’t have to go to classes or anything at a daily basis, so it’d be nice to keep myself on task now.

I am NOT a big fan of a lot of blogging software out there. You know, I don’t want to use WordPress or anything. That’s too bloated. I want to have something that just generates HTML pages, really simply not even a static page generator, just something. That’s very. Like makes sense, I don’t have to you know, write anything and markdown and convert it to HTML and do all the silly stuff. So I ended up writing a little blog system that might be worth checking out if you’re interested, so it’s actually written in less than a hundred lines of shell script.

In fact, I think it’s. If I actually look at it, I think it’s considerably less yeah. It’s just 71 lines, that’s all you need, but it does everything that I need and it gives you some nice different interfaces that might be interesting. Let me show you how it looks on my website so right now. I just have it here so they’re different in are different ways of looking at it, so the pH I’ve linked here is a rolling blog page, and this is originally the only thing I wanted, but it has other stuff that, in addition to this – and that is When I put up in a blog entry, it appears here as a you know, a new entry, of course they’re in chronological order, auto generates the date, gives me a title.

One of the nice things at is it generates links so it generates. The first link is like a link to the header, so if I click on this link, it actually takes me directly to the header and of course you can copy this, I’m not even on my website, I’m on the offline one, but it doesn’t matter, but you Can just copy the HTML that it generates in the standalone link if you want to link directly to that entry, so you can just copy this share it with some Linnell and it goes directly to that entry.

As you know, you probably have seen in other sites, but it’s nice having this automatic um. Additionally, in addition to that, it generates a link to a standalone page. So if you just want to view one alone, you can do that just as well. Now I don’t have the kind of thing where, like it cuts off after a point, I might integrate that later. But really my goal like what I want to have like what I like in blogs is when they’re just everything is just on one page and if you only use plain text, it doesn’t really get that big.

So my idea is like write, my blog page here. This isn’t part of the system necessarily, but mine is 2008. The HTML and my idea is after 2008 I’ll start using 2009 or something like that. That way, the pages don’t get too big, but my idea is like on this page. Everything should be there, but you know if you don’t like it, you can probably change the the script around, but so it generates these links that generates standalone pages and stuff, like that it also when you finalize a link, it automatically R adds it to the RSS Feed, so you can check my RSS feed and you’ll see that all the syntax is actually here as well.

Actually, let me just open up my RSS feed manually, so you’ll see that it generates it. Of course it takes that AIT’s HTML takes all the metadata. It needs and puts it into some kind of you know, gives it a unique ID the date it’s stuff like that, then it needs to be read properly by RSS readers, so all of that is like totally automatic. Let me show you how you actually use oh and the other interface I should say, which is something I’ve been playing around.

I don’t know if you checked out my website recently, but I’ve been playing around with this for other stuff. Like you know, Apache has this. You know we’re all familiar with it. Probably, but people don’t use them much, often like where a putt Apache can just generate the directory contents for a folder. So you can see the content of the contents of my proto-indo-european folder here. But the same thing is true: if the blog posts, so you can go to slash blog and these are actually out of order because I’ve been playing around with them, but if you don’t mess around with them since you’re, not figure out the cyst like, I am It’ll automatically add them and you can list them in chronological order or something like that, if you don’t know how to do this, for you know, Apache just look up how to make an Apache.

What is it like indexes or something like that? But anyway, so how does this blog system actually work? What’s the actual interface, so I’m going to go to my website directory and you’ll, see here the script here lb. That’s the name of my blog system is symlink. T’, so if you just run it by default, it gives you some directions, but I’ll talk about those in a second to add a new entry. It really just has three commands new finalize and delete so new.

It asks for a title. Let’s say you know, this is a blog post title and you go into it opens up, I think, and it might be vim. I might want to change it to your default editor, but it opens up. You know a page where you can actually add the content. So this is the content and of course this is you know it’s just an HTML, so you can do whatever you want here, save that and now, when you’re done, modifying the file, it’s actually stored, as it says here, it’s stored in a slash blog, slash, dot Drafts now, if you want to get rid of that draft, all you have to do is just RM it.

That’s all you have to do, but if you want to finalize it, what you should do is run lb finalize and that will give you a list of all your drafts. Currently I just have one so I’m going to pick that one and it’s now finalized. Now what that means is, it adds it first off to the HTML like rolling blog page. So here it is here. This is the content artists that are generally a standalone page. This is the content average of that nice and simple.

As the author name below and stuff on the standalone page – and it also it’s not going to work on my URL link, but I can because I haven’t updated my website. But if I go to my RSS feed offline you’ll see that here it’s all been added to the RSS feed, read the RSS feed or whatever. So all of that is automatic. Now, let’s say this is just in an example. I don’t actually want to push this to my website, so what you can do is just run lb delete to delete an old post and that generates a list of all the posts that you have, and I want to get rid of.

I should probably have this ordered chronologically. That would be a little easier, but yeah I’ll do that in a second. So all you have to do is select the one you want to get rid of say yes and then it actually it deletes the file. The standalone file – and it also deletes all that information from the RSS feed and the rolling blog page. So if I go back to this this, that entry is now going to be gone.

Okay, so that’s pretty much all the system. Does it again? It’s really simple! You just create blog posts and it’ll, convert it to RSS syntax and whatever else you need, if you want to delete a post, it will do that automatically. So one thing the one thing it doesn’t do since it’s not like a database or it doesn’t generate pages on the fly is: if you want to modify a post, you would basically have to modify the standalone page and the you know the the rolling blog list And the RSS feeds separately – that’s not the intended interface just because, and it would probably be a little more difficult to add something like that.

Just because there can be there can be a lot that varies between files. So I mean I I’m the kind of person I don’t like revise things like, I don’t believe in correcting spelling checks, there’s spelling mistakes or whatever. So I don’t care, but you know whatever, so it might not be for you if you’re the kind of person who is like that. That’s what I’m trying to say um and the last thing is what is the last thing just two seconds ago in my head, I was like.

Oh, I got ta say this one more thing. What what is the the last thing? I have to say. I don’t know, maybe that is it I’m going to forget, I’m going to turn off the camera and come back in a second. When I remember okay, I remember the last thing is the the other things it’s sort of important to remember is like when it’s generating these entries in the web, like the rolling blog page. All of this is like I mean it actually creates.

If you look at the source of it, it is a div of the class entry or something like this, so all the user interface or not user interface. All the decoration. I have like the fact that this is a slightly darker gray and the the sidebar here. All of that is just CSS, so for a lot of this stuff, if you want like a your blog to look totally different from mine, you can change it all the stuff like how Andrew individual entries look or how you know if you want them all as Individual squares on a page or something something totally unreadable, all of that’s a possibility.

All the thing does and well I should say you can go into the actual script and change any number of variables of the things you know that are at stake. So, of course you know here you can set your individual website, which is obviously not the same as mine you’re, going to want to change that or the stuff up here. You can also change, I think, yeah things like the header or the footer to the the individual page, the date that is displayed on the website.

This stuff is lower down because it has to be called lower down, but yeah, so you can play around with it again. It is less than 75 lines, so it doesn’t have all the functionality and that again it can’t, like you know, like change the content. I’ve already published blogs unless you want to do it manually, but yeah I’ve really enjoyed like this is pretty much all I need for a blog, so it’s probably the kind of stuff I’m going to be using so anyway, but that’s about it and I’ll see you Guys next time hope you learn something

Solving SEO with Headless Chrome (Polymer Summit 2017)

If you manage to pick up on my accent in the last five words, I am indeed Australian and it’s honored to be followed up by Trey, my fellow Aussie, as well prior to joining this team. I’d worked on the beloved chrome dev tools, one of my smallest, but maybe my greatest contribution was adding the ability to rearrange tabs in dev tools, there’s probably the greatest five lines I’ve ever written.

I did work another five other features. So if you find me afterwards feel free to ask me about them, and I might share dev tools trickle to more recently, I’ve had the humbling experience of building web components at all and witnessing all the incredible components that all of you have built and published. For example, the one and only Pokemon selector and if you’re the person who says but there’s a Hanyu, only 151 pokemon in the original set well there’s even an option that lets you set that too, so all kudos to Sammy.

For this, it was, however, in the process of building web components at all, which brings us to what we’re here to talk about today. So, first I’m going to cover my story of how I came to encounter this SEO problem while building web components. Our dog will then look at how I used have less chrome to solve this before diving into all the details of how that actually works and how you can use it. So I’m going to take a step back for a moment and talk about what I learnt in the process of building web components.

A talk. The first thing I learned was how the platform supports encapsulation through the use of web components with this encapsulation comes with inherent code reuse, which leads to a specific architecture. I also learnt about progressive web apps and how they can provide us with fast engaging experiences. I learned how the platform provides api’s such as service workers, to help enable those experiences, as I learned how to compose web components, to build a progressive web.

App we’ve heard from Kevin yesterday about the purple pattern: push render precache lazy load as a method of optimizing delivery of this application to the user and one of the architectures which enables us to utilize. The purple panel is the app shell model. It provides us with instant, reliable performance by using an aggressively cached app shell. You can see that for all the requests which hit our server, we serve the entry point file which we serve regardless of the route.

The client then requests the app shell, which is similar, but because the same URL across the application, we can combine that with a serviceworker to achieve near-instant loading on repeated visits. The shell is then responsible for looking at the actual route that was requested and then request. The necessary resources to render that route. So this point I’d learned how to build a progressive web app using client-side technologies like web components in polymer and how to use patterns such as the purple pan to deliver this application quickly to the user.

Then there’s the elephant in the room SEO for some of these BOTS they’re, basically just running curl with that URL and stop right there, no rendering no JavaScript. So what are we left with with this PWA that we built using the app shell model? We’re left with just your entry point file, which has no information in it at all, and in fact it’s the same generic entry point file that you serve across your entire application.

So this is particularly problematic for web components, which require JavaScript to be executed for them to be useful. This issue applies to all search engine indexes that don’t render JavaScript, but it also applies to the plethora of link rendering BOTS out there. There’s a social BOTS like Facebook and to but don’t forget the enormous number of link renting BOTS such as slack hangouts Gmail, you name it.

So what is it about the app shell model that I’d really like to keep well? For me, this approach pushes our application complexity out to the client. You can see that the server has no understanding of routes. It just serves the entry point file and he has no real understanding of what the user is actually trying to achieve. This allows our server to be significantly decoupled from the front end application, since it now only needs to expose a simple API to read and manipulate data.

The client that we pushed out to the application that we pushed out to the client is then responsible for servicing. This data to the user and mediating user user interactions to manipulate this data, so I asked: can we keep this simple architecture that we know and we love and also solve this SEO use case with zero performance cost? So then we thought what, if we just use headless chrome to render on our behalf, so here’s a breakdown of how that would work.

We have our regular users who are making a request and they would like a cat picture because who wouldn’t and as part of this approach, we ask our robot and to answer this, we look at the user agent string and check if it’s an own bot that Doesn’t render in this case the user can render so we serve the page as we normally would. The server responds with the fetch cat picture function and then the client can go and execute that function to get the rendered result by the way.

This is one of my kittens, which I fostered recently, which is super adorable. Now, when we encounter a boss, we can look at a user agent string and determine that they don’t render, and instead of serving that fetch cat picture function, we fire for a quest to headless Chrome to render this page on our behalf, and then we send the Serialized rendered response back to the bar, so they can see the full contents of the page.

So I built a proof-of-concept of this approach for web components rock and it worked. I wrote a medium post about it, and people really interested in this approach and want to see more of it. So, based on this response, I eventually decided that instead of my hacky solution that I would build it properly but then came the most challenging part of any project and I know you’ve all experienced it as well naming.

So I asked on our team chat for some suggestions and I got a tongue, so these are some of our top ones. There’s some great ones in their power renders use the platform as a renderer. However, today I’m very pleased to introduce render Tron. Let me render that, for you. Brenda Tron is a doc arised, headless, chrome, rendering solution. So that’s a mouthful, so let’s break it down. First off what is docker and why did I use it? Well, no one knows what it means, but it’s provocative in all seriousness.

Docker containers allow you to create lightweight images and standalone executable packages which isolate software from its surrounding environment in render Tron. We have headless chrome packaged up in this container so that you can easily clone and deploy this to wherever you like. So what about headless chrome? It was introduced in chrome, 59 for Linux and Mac chrome 60 for Windows, and it allows chrome to be run in environments which don’t have a UI interface such as a server.

This means that you can now use Chrome as part of any any part of your tool chain. You can use it for automated testing. You can use it for measuring the performance of your application, generating PDFs amongst many other things. Headless chrome itself exposes a really basic JSON API for managing tabs with most of the power coming from the dev tools protocol. All of dev tools is built on top of this protocol.

So it’s a pretty powerful API, and one of the key reasons that headless chrome is great. Is that now we’re bringing the latest and greatest from chrome to ensure that all the latest web platform features are supported with render Truong? This means that net your SEO can now be a first-class environment which is no different, the rest of your users. So just a quick shout out. This all sounds really interesting to you and you would like to include headless chrome in some other way in your to a chain.

There’s a brand new library, node library that was published just last week, that exposes a high level API to control chrome, while also bundling all of chrome inside that node package. So you can check it out on github at google chrome, slash puppeteer, so we’ve looked at the high level of how headless chrome can fit into your application to fulfill your SEO needs now it’s time to dive to how it works.

But I’ve been talking a lot. So, who wants to see render tron in action alright. So this is the hacker news PWA created by some of my awesome colleagues and it’s built using polymer and web components. It loads really fast and all-round performs pretty well. We can see that there’s a separate network requests which loads the main content that we see and we can guess that it’s affected by this SEO problem, since it uses web components which require JavaScript and it pulls the in data asynchronously.

So one quick way to verify this is by disabling JavaScript and refreshing the page, and once we do that, we can see that we still get the app header, since that was in the initial request. But we lose the main content of the page which isn’t good. So we jump over to render Truong the headless chrome service that is meant to render and serialize this for you. So I wrote this UI as a quick way to put in a URL and test the output from render Tron so first off.

What are we hoping to see because these bots only perform one request? We want to see that whole page come back in that one network request. We also want to see that it doesn’t need any JavaScript to do this. So take a look, I’m going to put in the hacker news URL and tell render Tron to render and serialize this and that using web components, and it renders correctly I’m going to disable JavaScript and verify that it still works.

So you can see it’s still there and it all comes back in that single network requests render tron automatically detects. When your PWA has completed loading. It looks at the page load event and ensures that it has fired. But we know that’s a really poor indication of when the page is actually completed. Loading, so Rena Tron also ensures that any async work has been completed and it also looks at your network requests to make sure they’re finished as well.

In total, you have a ten-second rendering budget. This doesn’t mean that it waits 10 seconds, though it’ll finish as soon as your rendering is complete. If this is insufficient for you, you can also fire a custom event which signals to rent Ron that your PWA has completed. Loading serializing web components is tricky because of shadow Dom which it straps away part of the dom tree so to keep things simple.

Rennet ron uses shady Dom, which polyfills shadow Dom this allows render tron to effectively serialize the dom tree so that it can be preserved. In the output, so let’s take a look at the news PWA, which you’ve all seen – and it’s also built by some of my other colleagues and we’ll plug that in to render tron will then ask render tron to render this as well and that I’m also using Web components, and then we have it.

So what do you need to do to enable this behavior with polymer 1? This is super easy and render tron doesn’t actually need to do anything simply append D’Amico’s shady to the URLs that you pass to render Tron and polymer 1 will ensure that shady Dom is used with polymer 2 and with web web components. V1. It’s recommended you use web components, loader jeaious, which pulls in all the right polyfills on different browsers.

You then set a flag to render tron tell it that telling it that you’re using web components, and it will ensure that the necessary polyfills that it needs for serialization get enabled so another feature of render Tron is that it lets you set HTTP status codes, these Status codes are used by indexes as important signals, for example, if he comes across a 404, it’s not going to link to that page, because that will be a really poor search result.

Now server, though, it’s still returning that entry point bar with a status code of 200. Okay, so it looks like every URL exists. Rena-Chan lets you configure that status code from within your PW, a which understands when a page is invalid, simply add meta tags. Dynamically is fine to signal to render on what the status code should be render. Tron will then pick these up and return that status code to the bot, so this approach isn’t specific to polymer or even web components, let’s plug in Fahnestock google.

Com and sees what happens when we serialize it. So that looks pretty good. Who can guess what javascript library was used to build? Google fonts angular render Trond works with any and all client-side technologies that work in Chrome and whose Dom tree can be serialized. The render tron endpoint also features screenshot capabilities, so that you can check that headless, chrome and the load detecting function are performing as you expect.

Unfortunately, this service is not fast for each URL that we render we spin up headless Chrome to render that entire page, so performance is strictly tied to the performance of your PWA. Renat Ron does, however, implement a perfect cache. This means that if we have rendered the same page within a certain cache freshness threshold will serve the cached response instead of rear-ending it again. So how can you get your hands on this today and how do you use it? Well, first, you need to deploy the random tron service to an end.

You’ll need to clone the github repo at Google, Chrome, slash, magnetron, and it’s built primarily for Google cloud. So it’s easy to deploy there. But if you remember this is a darker container, so you can deploy this to anywhere, which supports a docker image. So to make things simple for you to test our. We have the demo service endpoint, which you can hit at render Tron appspot.Com and that’s the one with the UI that we saw earlier.

It is not intended to be used as a production endpoint. However, you are welcome to use it, but we make no guarantees on uptime. Having this as a ready to use service is something we might consider based on the interest receive. So, just in case you’re wondering my boss’s twitter handle is at met, Matt s McNulty, just in case. You want to tell him how awesome I am so once we have that endpoint up you’re going to need to install some middleware in your application to do the user agent splitting that I was talking about earlier.

So this middleware needs to look at the user agent figure out whether or not they can render and if not proxy, the requests through the render tron endpoint, if you’re using purple server, which is a node server designed to serve production applications using purple. You simply need to specify the bot proxy option and provide it with your rennet on endpoint, if you’re using Express, there’s a middleware that you can include directly by saying app, don’t use render on top make middleware with the proxy endpoint and whether or not you’re using Web components, if you’re not using either of these check the docs for a list of community maintained bit aware, there’s a firebase function there, as well as a list of existing middleware that render China is compatible with.

If it’s not listed, it’s also fairly simple to roll. Your own middleware by simply proxying based on the user agent string, and that’s it, that’s all the changes you need to make to use, render tron today and all these bots can now be happy. Brenda Tron is available to use today compatible with any client-side technologies, including both polymer 1 and polymer 2. Thank you.

SEO: where search engine results come from

So here’s a search result and a series of search results. Anyways, and you can see the top three right here. The first thing to notice is this big link that everyone clicks on the content inside here is the title tag of your HTML file. So if I have an empty HTML file right here, whatever you type in between the title tags here shows up right here.

So that’s a very important section for keywords: it’s the section that most people read not too many people actually read the description underneath. But the title here is extremely important because that’s what people see as well as Google uses the keywords from the title when displaying search results. Another thing that’s important to our website is this description. Underneath here this description can come from one of two places: either the Meta Description tag in our HTML, so we could have a tag like this at a name equals description and content equals whatever and put a small description in here.

So this will either come from that tag or it will come from the first paragraph on your page, so it will come from here now, there’s no way for us to tell Google which to choose either the first paragraph or the Meta Description. Google just figures out whichever one is more appropriate, whichever one is more targeted to humans and that’s what we’ll be choose chosen. So the description here and the title here, we have control over another place.

That Google looks for keywords, as you can see. Right here is the URL you’ll notice that the keyword, dinosaur or dime soars down here has been highlighted in the URL, showing you that the URL that you choose for your website actually impacts your search results. There’s a few other things right here. These links underneath the search results. We don’t really have any control over those Google figures out.

What links are important and shows them at the bottom, underneath the search results right here for this movie or this is the TV series. Actually, you can see there’s a rating, so it’s giving us a star rating and a numerical version and how many votes this information here is taken from the enhanced metadata supplied by the website and then we’ll look at that in future articles. So what we’re seeing here in the search results page is a few things.

The blue is the title. The green is the URL that we’ve chosen and you can see it’s matching keywords in that, and then this here is either the first paragraph on the site or the meta description. So that’s where Google gets the content to display in its search results page and the same thing applies to other search engines like DuckDuckGo and Bing. So the same sort of techniques are applied for those also
