Page Speed Checker
About Page Speed Checker
Our Page Speed Checker measures how quickly any webpage loads and identifies specific performance bottlenecks slowing it down. Google has confirmed page speed as a ranking factor, and faster pages consistently achieve higher positions in search results.

Beyond SEO, page speed directly impacts user experience and conversions. Amazon found that every 100ms of load time cost them 1% in sales. Our tool helps you pinpoint exactly what's slowing your site so you can fix it effectively.
Key Page Speed Metrics
- Time to First Byte (TTFB) - server response time
- First Contentful Paint (FCP) - first visible content
- Largest Contentful Paint (LCP) - main content loaded
- Total Blocking Time (TBT) - JavaScript impact
How to Use the Page Speed Checker
- Enter the full URL of the page you want to test, including https://.
- Click the check button and let the tool load the page and capture timing data.
- Review the summary metrics for TTFB, FCP, LCP and TBT alongside an overall speed rating.
- Note which elements or requests contributed most to the delay, such as large images or render-blocking scripts.
- Apply fixes - compress images, enable caching, minify code - then re-test the same URL to confirm the improvement.
- Re-check the page periodically, especially after adding new plugins, scripts or media, since these commonly reintroduce slowdowns.
- Compare results over time to track whether ongoing optimization work is actually moving the needle for visitors on both mobile and desktop connections.

Frequently asked questions
Why does page speed matter for SEO?
Google uses page speed (Core Web Vitals) as a ranking factor, and slower pages also see higher visitor bounce rates - faster pages tend to both rank better and convert better.
What usually causes a slow page speed score?
Large unoptimized images, too many render-blocking scripts/stylesheets, lack of browser caching, and slow server response time are the most common culprits.
Do mobile and desktop scores differ?
Yes - mobile devices typically have less processing power and slower networks, so mobile scores are often lower than desktop scores for the same page; Google primarily uses mobile performance for ranking.
