How WordPress Caching Works
What is Caching?
Caching stores static versions of your WordPress pages so they don't need to be regenerated on every visit. Instead of processing PHP and querying the database repeatedly, cached pages load instantly from storage.
Why WordPress Needs Caching
WordPress is a dynamic CMS that generates pages on-demand by:
- Processing PHP code (server-side scripting)
- Querying the MySQL database (sometimes dozens of queries per page)
- Assembling the HTML output from theme templates
- Sending the completed page to your browser
This process takes 500-2000ms on typical shared hosting like HostGator. With caching, this drops to 50-200ms.
Types of Caching
- Page Caching (Most Important): Stores complete HTML pages for instant delivery
- Browser Caching: Tells browsers to store static assets (images, CSS, JS) locally
- Object Caching: Stores database query results in memory (Redis, Memcached)
- CDN Caching: Distributes content across global servers (Cloudflare, BunnyCDN)

Frequently Asked Questions
Can I use multiple caching plugins at once?
No. Never activate multiple caching plugins simultaneously. They will conflict and potentially crash your site. Choose one and stick with it.
Will a caching plugin improve my Core Web Vitals?
Yes, but only partially. Caching helps LCP and INP by serving pages faster, but you'll still need image optimization, lazy loading, and CDN for optimal scores.
What's the difference between free and premium caching plugins?
Free plugins offer basic page caching. Premium plugins add: automatic critical CSS, lazy loading, JavaScript delay, unused CSS removal, database optimization, and better support.
Do I need a caching plugin if my host has caching?
Maybe. Server-level caching doesn't include browser caching, minification, or lazy loading. Even with good hosting, a caching plugin adds significant improvements.
Will a caching plugin work with Cloudflare?
Yes. All major caching plugins integrate well with Cloudflare. In fact, pairing them provides optimal performance (plugin handles WordPress, Cloudflare handles CDN). See our Cloudflare WordPress setup guide for details.
Which plugin is best for HostGator specifically?
FlyingPress ($49/year) or WP Rocket ($59/year). HostGator's infrastructure requires aggressive optimization. Free plugins won't achieve Core Web Vitals compliance on HostGator shared hosting.
Conclusion
Best overall: WP Rocket (ease + performance)
Best for Core Web Vitals: FlyingPress
Best free: W3 Total Cache (if technical)
