Step-by-Step Instructions
1. Access AccelerateWP
- Log in to DirectAdmin
- Go to Extra Features → AccelerateWP
- Select the domain you want to optimize
You will see a dashboard showing your site's performance status.
2. Install the AccelerateWP Plugin
If not already installed:

No manual upload required.
3. Enable Full-Page Caching

Images will be optimized automatically as they are uploaded.
6. CDN Integration
If your host provides a CDN:

This reduces latency for global visitors.
