Why Page Speed Matters
Better User Experience
Fast sites retain more visitors, reduce bounce rates, and increase conversions. Every additional second of load time significantly decreases user satisfaction.
Google Ranking Factor
Page speed is a direct ranking factor, especially for mobile searches. Google prioritizes fast sites in search results.
Impact on Conversions
Faster sites have higher conversion rates. A 0.1-second improvement in speed can increase conversions by up to 8%.

Frequently Asked Questions
Find answers to common questions about this tool
What is page speed testing?
Page speed testing measures how quickly your website loads and performs. It analyzes various performance metrics including Core Web Vitals, loading times, and user experience indicators that affect search rankings.
Why is page speed important for SEO?
Page speed is a crucial Google ranking factor. Core Web Vitals (LCP, FID, CLS) are official ranking signals. Faster websites provide better user experience, have lower bounce rates (53% of users abandon sites loading >3 seconds), and tend to rank higher in search results.
How do I improve my page speed?
Common improvements include: optimizing images (use WebP/AVIF, compress, lazy loading), minifying HTML/CSS/JavaScript, leveraging browser caching, reducing server response time, using a CDN, eliminating render-blocking resources, and reducing HTTP requests.
What are Core Web Vitals?
Core Web Vitals are Google's official page experience metrics: Largest Contentful Paint (LCP) - loading performance (target <2.5s), First Input Delay (FID) - interactivity (target <100ms), and Cumulative Layout Shift (CLS) - visual stability (target <0.1).
What is a good page speed score?
A good page speed score is 90-100 (green), 50-89 needs improvement (yellow), and 0-49 is poor (red). However, focus on actual user experience metrics rather than just scores. Real-world loading times matter more than synthetic scores.
How often should I test page speed?
Test page speed after any significant website changes, at least monthly for monitoring, and before/after major optimizations. Regular testing helps identify performance regressions and track improvement progress over time.
