Why WordPress Speed & SEO Matter More Than Ever
Before choosing plugins, you must understand why they matter:
- Google uses page speed & Core Web Vitals as ranking factors
- Faster sites have lower bounce rates and higher engagement
- Speed directly increases AdSense RPM & affiliate conversions
- SEO plugins help structure content for search engines & AI summaries
A 1-second delay in load time can reduce conversions by up to 20%. That’s real money lost.
