Is this tool really free?
Yes. There's no sign-up. It uses Google's free PageSpeed Insights service, so you can run as many tests as you need.
Why are mobile scores lower than desktop?
The mobile test simulates a mid-range phone on a slower connection, which is how Google judges most pages. A lower mobile score is normal and the one to focus on.
Why does my score change between tests?
Speed scores move a little with server load, ads and network conditions. Run the test two or three times and look at the trend. SEO checks stay the same unless the page changes.
Does a 100 SEO score mean I'll rank first?
No. A perfect score means the page has its technical basics right. Rankings also depend on content, links, reviews and competition, which this test can't measure.
