How to Optimize a CMS for SEO Page Speed
IntermediateQuick Answer
TL;DR
Target Google's Core Web Vitals thresholds: LCP under 2.5 seconds (fast server response + optimized images), INP under 200 milliseconds (minimal JavaScript), and CLS under 0.1 (explicit dimensions on all media). Use SSG or ISR for fast TTFB, serve content from a CDN, compress with Brotli, and monitor continuously via Google Search Console. Page speed is a confirmed Google ranking signal.
Key Takeaways
- Core Web Vitals (LCP, INP, CLS) are Google ranking signals — hitting "Good" thresholds matters for SEO
- SSG and ISR deliver the fastest possible TTFB by serving pre-rendered HTML from a CDN
- Image optimization is the highest-impact single change for most CMS sites
- Monitor real-user data in Google Search Console, not just lab scores from Lighthouse
