Frequently Asked Questions
What to expect from the SEO Tools on this page.
No. Every SEO tool here runs in your browser and needs no sign-up. The one exception is the Page Speed Auditor, which queries Google PageSpeed Insights and needs a free API key configured by the site owner.
The tools report exactly what they can measure from the input you give them — tag lengths, heading structure, keyword frequency, robots directives. They do not estimate ranking difficulty or authority, because those figures come from proprietary datasets no free tool can access honestly.
You can paste a competitor's markup into the analyzers and inspect it. The tools do not fetch remote pages for you, so you will need to view the source yourself first.
No. They cover on-page checks and generation tasks well. Crawling, rank tracking and backlink analysis need a paid platform with its own index.
