3️⃣ Upload the WP Rocket zip file and click 'Install Now'.
4️⃣ Activate the plugin: WP Rocket works right away, no configuration needed.

Step 2: Basic configuration of WP Rocket

1. Cache settings

Go to Settings > WP Rocket > Cache and turn on the following options:
✅ Mobile caching: speeds up the mobile view.
✅ User cache: useful for logged-in users (e.g. in WooCommerce).
✅ Cache lifespan: 10 hours by default; adjust it based on how often you update.

2. Optimizing files

Go to File Optimization:
✅ Minify HTML: removes unnecessary code and whitespace.
✅ Combine & minify CSS: reduces the load time of styles.
✅ Defer JavaScript (defer): prevents render-blocking scripts.

⚠️ Test thoroughly! Some themes can conflict with JavaScript optimization.

3. Media optimization

In Settings > Media:
✅ Enable Lazy Load: loads images only when they come into view.
✅ Disable emojis: avoids extra load time from WordPress emojis.
✅ WebP compatibility: works with image optimization plugins such as Imagify.

4. Cleaning up the database

Go to Settings > Database and run these optimizations:
✅ Delete revisions & drafts: saves storage space.
✅ Clean up spam & transients: keeps the database efficient.
✅ Automatic cleanup: set it to daily or weekly.

5. Setting up a CDN (Content Delivery Network)

Do you use a CDN such as Cloudflare or BunnyCDN? Connect it under CDN settings.

Step 3: Advanced settings for maximum speed

1. Enabling preloading

Preloading makes sure pages are stored in the cache right away.
✅ Enable sitemap-based preloading (works well with Yoast SEO).
✅ Activate the 'Preload bot for faster updates.

2. Limiting the Heartbeat API

The WordPress Heartbeat API handles communication between the browser and the server. This can cause unnecessary load.
✅ Go to WP Rocket > Heartbeat and limit it to 120 seconds.

3. Object caching (extra boost for WooCommerce)

Do you have a WooCommerce site? Activate Redis or Memcached for object caching. This keeps WordPress from having to run the same database queries every time.
