Creator Website PageSpeed Checker
Score your creator site's load speed, SEO, accessibility and Core Web Vitals on mobile or desktop — powered by Google Lighthouse. Slow pages lose viewers before they even see your content.
How it works
This tool runs your page through Google's PageSpeed Insights, which uses the Lighthouse engine to load your page in a real browser and measure how it performs. You get four scores out of 100 — Performance, SEO, Accessibility and Best Practices — plus the Core Web Vitals that Google uses in search ranking: Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS) and Total Blocking Time (TBT). Choose Mobile or Desktop before you test, because the two can score very differently.
How to use this tool
- Paste the full URL of the page you want to test, including https://.
- Pick Mobile or Desktop — Mobile is what Google weighs most for ranking.
- Hit Check PageSpeed and wait for the scores (the test runs on Google's servers, so it takes a few seconds).
- Read the four category scores and Core Web Vitals. Green is good, amber needs work, red is a priority fix.
- Re-test after changes to confirm your improvements landed.
Frequently asked questions
Why is my mobile score lower than desktop?
PageSpeed simulates a mid-range phone on a slower network for the mobile test, so it's a tougher benchmark than desktop. Since Google ranks primarily on the mobile experience, the mobile score is the one to prioritise — a strong mobile score almost always means a strong desktop score too.
What are Core Web Vitals and why do they matter?
Core Web Vitals are three metrics Google uses as a ranking signal. LCP (Largest Contentful Paint) measures how fast the main content loads — aim for under 2.5s. CLS (Cumulative Layout Shift) measures visual stability — aim for under 0.1. TBT (Total Blocking Time) approximates how responsive the page feels — lower is better. Weak vitals can hold back your search rankings even if your content is great.
What's a good Performance score?
90–100 is good (green), 50–89 needs work (amber), and 0–49 is poor (red). Performance is the hardest score to max out because it depends on images, scripts and hosting. For a creator site, aim for 90+ on desktop and at least 50–70 on mobile — most improvements come from compressing images and cutting unused scripts.
Can I test any website or just my own?
Any public URL works — your own site, a competitor's, or a page you're thinking of collaborating with. The page just needs to be publicly reachable (not behind a login or password). Testing a competitor's site is a quick way to benchmark where you stand.
Why did my test fail or time out?
The most common causes are a typo in the URL, a page that's behind a login, or a site that's temporarily down. Make sure you included https:// and that the page loads in a normal browser. Very large or slow pages occasionally time out — wait a moment and try again.
