What is Angular Universal, and how does it improve SEO?

Short answer: Angular Universal is a technology that enables Server-Side Rendering (SSR) of Angular applications. Instead of rendering the app purely in the browser (client-side), the initial HTML is rendered on the server and sent to the client. Improves SEO because search engines get fully rendered HTML content immediately, which they can index better. Also improves perceived performance and faster first paint.

Real-world example (ShopNest)

ShopNest admin can be built in Angular with modules/components, services for API calls, and reactive forms for product edit.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
