Frequently asked questions
Is the SEO check really free?
Yes. All tools on RankTutor are free and need no account. The SEO check uses Google's free PageSpeed Insights service, which has a daily limit, so on very busy days you may have to try again a little later.
What does the free SEO check test?
It loads one page like a phone or a computer and checks the SEO basics (title, description, indexing, links, images), loading speed with the Core Web Vitals, accessibility and best practices like HTTPS. Every problem comes with a plain explanation and a fix.
Do you store my website or results?
No. The tools run in your browser. For the SEO check, the address you enter is sent to Google PageSpeed Insights, and the result goes straight back to your browser. We have no server that sees it.
Why does my site get 100 for SEO but still doesn't rank?
The SEO score checks technical basics on one page. Rankings also depend on your content, how well it matches what people search for, links from other sites, reviews and local signals, which no single-page test can measure.
How is this different from the RankTutor app?
The website tools check one page or one file at a time. The iPhone app checks up to 100 pages of your site, connects to Google Search Console, tracks keywords and warns you when clicks drop.
Who makes RankTutor?
RankTutor is made by Julian Lau, an independent app developer in Bonn, Germany (JL Apps). There's no investor and no data business behind it.
