Free SEO tools: FAQ
Are these SEO tools really free?
Yes. Every tool in the catalog opens without payment. Guests get a daily check limit per tool, a free account triples it, and a Pro subscription removes the limits.
Do I need to sign up?
No. Open a tool, enter a URL or text and run the check. An account only raises the daily limit and gives access to the promotion services.
Where should I start with a website check?
Start with the SEO audit of a page: it flags problems with meta tags, headings, indexability and speed. Then check broken links and redirects, robots.txt and the sitemap, and confirm indexing with the index checker.
Are my files and texts uploaded?
It depends on the tool. Some run entirely in your browser, such as the EXIF remover, the Gemini watermark remover and the image compressor. Website checks fetch the URL you enter from our server, and text and file analysis runs on the server; each tool page says which applies.
Can AI detectors be trusted 100%?
No. AI detectors for text and images give a probability and a list of signals, not proof. For images the strongest signal is a metadata record (C2PA, IPTC); its absence proves nothing.
