Server-side rendering (SSR angular) with Angular Universal (SEO in angular).

A normal Angular application executes in the browser, rendering pages in the DOM in response to user actions. Angular Universal runs on the server, generating static application pages that later get bootstrapped on the client. This means that the application generally renders more quickly, giving users a chance to view the application layout before it becomes fully interactive.

Why should you use server-side rendering?

There are several reasons why you should use Server-Side Rendering in Angular application.

SSR supports Search Engine Optimization (SEO). Because the page is rendered on the server, search engines can parse it.

When shared, social media platforms such as Facebook and Twitter can display a preview of the site.

It makes the first-page Load Faster

For a better user experience, quickly displaying the first page is vital. Pages that load promptly show better performance. Your application needs to launch faster to keep users engaged before they choose to do something else.

Angular Universal allows you to create landing pages for your application that look like the entire application. Because the pages are pure HTML, they can be viewed even if JavaScript is disabled. The pages do not handle browser events but support site navigation through router links.

You’ll serve a static version of the landing page to keep the user’s attention. At the same time, the complete Angular application will be loaded behind it. After the entire application loads, the user perceives near-instant performance from the landing page and receives the whole interactive experience.
