Its Time to Make SEO in Angular Easy by Following these Steps

Angular is one of the most in-demand languages. It is often the first choice for developing friendly web apps, it also comes with a major hurdle – SEO.

Developers love Angular for the ease it offers. But search engines do not share the same affinity. So, if you are running a website build on Angular, you may have to put in your extra bit for SEO. However, don’t you worry, it will be worth everything.

Angular runs on the client-side so the first thing to load when your app starts would be an empty HTML shell, the script will then populate the pages. As a result, search engines like Bing, Yahoo, DuckDuckGo, and Yandex might not be able to index the page.

SEO Issues in Angular

Although it is not entirely true that web apps build on Angular cannot rank but the statement holds a bit of truth as well. Since Angular can pose problems when it comes to SEO. This is because of many reasons like:

Speed

Angular apps are generally slow to load. While this can increase the bounce rate of your app this also sends a negative impression to the search engine as it decreases the site speed. And this, negatively affects the page speed ranking factor.

Script

Secondly, it heavily depends on script. So, if you check the page source, which is the part that search engine crawls, you won’t see any content there. This also makes ranking it difficult. Although Google claims it can index script-driven files, this might not always be the case and you wouldn’t want to risk losing your traffic because of it.

The Solutions

Every dark cloud has a silver lining. The good news is that this holds true for SEO in Angular too. Though there are many ways in which you can resolve the issues. Here are a few of them.

Server-side rendering

When you use this, it renders each HTML page on the server in the run time. This method has the potential to decrease the load speed of the page, especially for the ones with multiple requests at a time.

Pre-rendering

If you resort to this, it will render an HTML file for every URL for the given time. With this, you can ensure that the pages are already ready so that they load faster when requested. This happens as all HTML files for your app are built in advance so that the pages are ready to load fast upon request.

Dynamic Rendering

Herein you use various tools that generate HTML static files. After this, direct your webserver such that it direct searches to these pages that are pre-rendered. Whereas your users will have access to the normal content. Though this solves the crawling issue but does little to help the slow speed issue. That is why Angular Universal is a better option.

Angular Universal

With Angular Universal, you can go for server-side rendering SSR. This lets you pre-render HTML & CSS content that is normally visible to the user in advance. As a result, the user will load a static HTML page. After this, the content is transferred from the server to the browser with the help of TransferState API.

It also comes with the added benefit of keeping your application layer intact as it adds a second element in the rendering layer. As a result, DOM is generated as a string so that it can be served as per the browser’s request. You can run it in the three easy steps as given below:

  • Install the necessary dependencies – Use the following code in the Node Package Manager
  • Update the Angular app – This step involves four easy steps viz adding universal support, creating a new module with the name AppServerModule, exporting it and a file in config in JSON format.
  • Build a Universal Bundle using CLI – Update the angular.json file in the source directory with the code:

This will give you:

  • Set up the server such that it can run a Universal bundle
  • Run the app on the server using the command:

There is another easier way to install Angular universal- by using the @ngtoolkit/universal. This can be easily done with the three steps below.

Setting title and meta tags for Angular SEO

Anyone familiar with SEO can not deny the need for optimized Title and SEO. Angular understands this and thus offers a simple solution. You can easily do this by updating home.component.ts file. Thereafter if you want to apply similar changes to any page – like blog add it to that as well – blog.component.ts file.
