Frequently Asked Questions
What are Core Web Vitals and why do they matter?+
Core Web Vitals are Google's official user experience metrics: LCP (Largest Contentful Paint) measures loading speed, FID/INP measures interactivity, and CLS (Cumulative Layout Shift) measures visual stability. Since 2021, they're official Google ranking factors affecting search visibility.
What's a good PageSpeed score for SEO?+
Aim for 90+ on mobile and desktop for optimal performance. Scores of 50-89 need improvement, and below 50 require immediate attention. However, Core Web Vitals thresholds matter more than the overall score: LCP under 2.5s, FID under 100ms (INP under 200ms), and CLS under 0.1.
Why is mobile vs desktop testing important?+
Google uses mobile-first indexing, meaning mobile performance is prioritized for rankings. Mobile devices typically have slower connections and less processing power, so mobile scores are often lower. Our tool tests both to help you optimize for mobile while maintaining desktop performance.
How often should I test page speed?+
Test weekly for high-traffic pages, monthly for regular content pages, and immediately after: site updates, adding new scripts/plugins, design changes, hosting migrations, or when you notice traffic drops. Set up automated monitoring for critical pages to catch performance regressions early.
What causes slow page speed and how can I fix it?+
Common causes include: large unoptimized images (use WebP, lazy loading), render-blocking JavaScript/CSS (defer non-critical resources), slow server response (upgrade hosting, use CDN), excessive plugins (audit and remove unused), no caching (enable browser and server caching), and large DOM size (optimize HTML structure).
Does page speed directly affect Google rankings?+
Yes! Page speed is a confirmed ranking factor, especially for mobile searches. Poor Core Web Vitals can hurt rankings even if your content is excellent. Fast sites also get more crawl budget, better user engagement (lower bounce rates, longer sessions), and higher conversion rates - all indirectly benefiting SEO.
