What is Angular Universal and How to Make an Angular SEO Friendly Website

Google released a typescript-based free and open-source web app framework Angular v14 on June 2, 2022. The open-source web app framework innovation with typed forms and standalone components to new elements in the Angular CDK (component dev kit) is now even more versatile.

Although Angular Universal is hard for search engines to index because web scrapers cannot scrape dynamic data, and their display on multiple sites may vary, angularJS developers can send the precompiled initial view from the server to reduce end-user load time. 

Angular Universal offers considerable benefits to business entities through app flexibility with filters and multi-viewing routing while creating a Single page. You can hire AngularJS developers for an appealing user experience at hard-to-resist rates.

What is Angular Universal? 

Angular Universal overtook Python in ranking as it was voted the second most extensive professional web developer language in a 2019 Stack Overflow Developer Survey. Google first introduced the language that provides static typing in 2009. However, this (JS) JavaScript-based framework for creating mobile and desktop web apps, first released by Google in 2009, has evolved significantly since then.

So, what is Angular Universal, and how does it work?

Angular Universal is a server-side rendering solution that helps the client to leverage by producing static application pages that run on the server. The primary benefit of the Java-scrip-based language is that it loads fast and gives ample time to view the application’s layout before becoming fully operational. The open-source web app framework has surged in popularity because it makes the developer’s code easy to decipher.

What is the Need for Angular Universal? 

Angular is a comprehensive, responsive web design framework with only one recommended method for creating a module, function, or plugin. 

Here are three primary reasons to develop a Universal version of your application:

Search Engine Optimization (SEO) Can Help Web Crawlers  

Build a static version of your application to quickly and comfortably search, link and navigate without using JS.

Do you Need Search Engine Crawlers? 

People spend much time searching for areas of interest on the web. In the same way, a web crawler searches for new content on websites, and when it finds some, it fetches the pages and memorizes its URL. The search engine bots get busy in real-time listing connected webpages. 

Developers refer to web crawlers as spiders, web robots, bots, or automated indexers because of how they function. The bot does not conduct a random sampling but downloads the whole frequently searched and viewed webpage. The automated indexers work to limit links, conduct path ascending crawling and standardize URLs.

Boost Mobile and Low-Power Device Performance

Devices that do not support or execute JS perform better with the service rendering (without JS) applications.

Display the First Page Instantly With a First Contentful Paint (FCP)

A quick display of the initial page may encourage user engagement, for pages that load faster perform better.

Step-by-Step Implementation of Angular Universal 

Step 1– Generate the New Angular Universal Bundle

By running the following script, we can rapidly add a Universal bundle to the client application:  

ng generate universal –client-project <name of your client project>

This program will generate the Universal bundle of the main.bundle.js file and contains a program identical to the client application and the server-side rendering layer.

Step 2: Use the Angular Universal Bundle for App Pre-Rendering

Use the primary HTML route to pre-render HTML by coding a simple command line to the tool and creating a text file to store the output. The text file will simplify the Express Server creation process. The program file will be named prerender.ts and saved in the app’s root folder. The program pre-renders the main route app by calling the function renderModuleFactory()


Step 3: Choosing the Document Property

You find the document property in the form of a string that holds the template to render. Execute the program to instantaneously create the prerender.html with rendering process results. The document attribute is a string that contains the renderable template. The run utility command is as follows:

SteRun the Utility and Frontend Build 

The source code for this application is accessible on GitHub and easy to find under the ts-node branch. The result of using renderModuleFactory() will be a new prerender.html output file, including the impact of calling renderModify(). And here is how the content file will appear.

Also, create both the client-side build output and the server-side version source code to collect all the resources we need in one place– the client-side index.html file. The result will include HTML and CSS and the script and link tags used to load all the application styles. The dist folder appears as follows:

The default setting for the angular application is client-side execution which is why the HTML shell is the first thing that loads during the Angular application executions. The libraries facilitate updates, specify the needed meta tag options, and configure Angular Universal accordingly to start in pre-render mode.

Run Pre-Rendering Process

The angular website does have the necessary HTML to allow Google’s web crawlers to do their job by retrieving essential data from the API calls. Enable bots indexing using a workable solution, the dynamic rendering tool. 

The pre-rendering tools create the necessary HTML files for automated indexers to crawl without any difficulty. Finally, redirect traffic to the angular website setting up a web server to the spiders to the pre-rendered pages.

Select and Insert Meta Tags

Meta is an Angular service that enables the swift assignment of various Meta tags to multiple pages. Angular provides titles and metaservices. A search engine can utilize the page title to identify the information stored in the browser. 

Here are some meta-services for adding, updating, and removing HTML meta elements.

addTag() : Include one meta tag

addTags() : Include more than one meta tag

updateTag() : To update the meta tag 

getTags() : To get HTMLElement for any particular meta selector

removeTag() : To remove the meta tag

removeTagElement() : To remove meta tags for a particular HTMLElement



A viewer’s attention span is short and restricted, and they will not just look at a blank screen waiting for it to reveal what interests them. Instead, they will click and move on to another site that will satisfy their needs. 

To convert leads to sales, businesses must engage with prospective customers, which is possible by fast-loading sites encouraging visitors to stay on. Angular Universal is a versatile fast-loading interface that combines server-side rendering and client-side execution in one single app to give a user a dynamic page experience.

Hire AngularJS developers to implement Angular Universal and increase the SEO potential of your app.
