What is Page Speed?
Page speed measures how quickly a webpage loads and becomes interactive for users. Google considers page speed a ranking factor, with faster sites typically performing better in search results. Core Web Vitals metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) provide specific benchmarks for page speed optimization.

What You Need to Know about Page Speed
Mobile Performance Is Critical
Mobile-first indexing means your mobile page speed directly affects rankings. Sites that load quickly on mobile devices maintain better search visibility and user engagement.
Core Web Vitals Define Success
Google’s Core Web Vitals—LCP, FID, and CLS—provide specific performance targets. Meeting these benchmarks improves rankings and signals quality user experience to search engines.
Speed Affects Conversion Rates
Faster pages convert better. Users abandon slow-loading pages, with even one-second delays reducing conversions. Page speed optimization directly impacts revenue, not just rankings.
Image Optimization Delivers Quick Wins
Unoptimized images are the most common speed killer. Compressing images, using modern formats like WebP, and implementing lazy loading can dramatically improve load times without sacrificing quality.
Server Response Time Matters
Slow server response (Time to First Byte) delays everything else. Quality hosting, caching strategies, and content delivery networks reduce server response time and improve overall page speed.
Third-Party Scripts Add Hidden Weight
Tracking pixels, analytics, and advertising scripts slow pages down. Auditing and minimizing third-party scripts, or loading them asynchronously, prevents these tools from blocking page rendering and harming performance.
Frequently Asked Questions about Page Speed
1. What’s the difference between page speed and site speed?
Page speed measures how quickly a specific page loads, while site speed refers to the average load time across multiple pages. Both matter, but individual page performance impacts rankings.

Google recommends pages load in under 2.5 seconds for Largest Contentful Paint. Faster is better—sites loading under two seconds typically see better rankings and conversion rates.
3. Does page speed affect mobile rankings differently?
Yes, mobile page speed is weighted heavily in rankings due to mobile-first indexing. Mobile users expect fast experiences, and Google prioritizes sites that deliver speed on mobile devices.
4. Can page speed improvements increase revenue?
Absolutely. Faster pages reduce bounce rates and improve conversion rates. Studies show that even small speed improvements lead to measurable increases in revenue, especially for ecommerce sites.
