# Rendering Strategies
Angular supports multiple rendering strategies to optimize for SEO, performance, and interactivity.
## 1. Client-Side Rendering (CSR)
**Default Strategy.** Content is rendered entirely in the browser.
- **Use case**: Interactive dashboards, internal tools.
- **Pros**: Simplest to configure, low server cost.
- **Cons**: Poor SEO, slower initial content visibility (must wait for JS).
## 2. Static Site Generation (SSG / Prerendering)
Content is pre-rendered into static HTML files at **build time**.
- **Use case**: Marketing pages, blogs, documentation.
- **Pros**: Fastest initial load, excellent SEO, CDN-friendly.
- **Cons**: Requires rebuild for content updates, not for user-specific data.
## 3. Server-Side Rendering (SSR)
Content is rendered on the server for the **initial request**. Subsequent navigations happen client-side (SPA style).
- **Use case**: E-commerce product pages, news sites, personalized dynamic content.
- **Pros**: Excellent SEO, fast initial content visibility.
- **Cons**: Requires a server (Node.js), higher server cost/latency.
## Hydration
Hydration is the process of making server-rendered HTML interactive in the browser.
- **Full Hydration**: The entire app becomes interactive at once.
- **Incremental Hydration**: (Advanced) Parts become interactive as needed using `@defer` blocks.
- **Event Replay**: Captures and replays user events that happened before hydration finished.
## Decision Matrix
| Requirement | Strategy |
| :------------------------------ | :------------------- |
| **SEO + Static Content** | SSG |
| **SEO + Dynamic Content** | SSR |
| **No SEO + High Interactivity** | CSR |
| **Mixed** | Hybrid (Route-based) |
