About The SERP Master

There are hundreds of free SEO tool sites, and a lot of them share the same problem: the tool is a demo. You paste a URL, a progress bar runs, and you get a score that was never calculated from your page at all. Some do not even fetch the page.

Everything here works the other way round. When a tool says it analysed your page, it fetched that page server-side, parsed the HTML, and counted what was in it. When it gives you a score, the checks behind that score are listed so you can see what produced it.

• Calculations are real. Word counts, keyword density, reading time, character limits and QR scanability are all computed from your input, never estimated or faked.
• Nothing is uploaded unless it has to be. Most tools run entirely in your browser. The ones that need a server are the ones that fetch a URL or call an AI model, and our privacy policy names them individually.
• AI is used where it helps and nowhere else. 14 of the 70 tools use AI, and each says so plainly. Counting words does not need a language model; writing a meta description does.
• Every AI tool degrades gracefully. If AI is unavailable, the calculated parts of that tool carry on working rather than the page breaking.

The QR code generator has a scanability score. Plenty of tools have something similar, usually a traffic light based on rules of thumb. The QR Code Generator also rasterises the finished code and runs a real QR decoder over it, because only an actual decode proves a styled code still reads.

That check immediately found two of our own design presets producing codes that would not scan, while every rule of thumb called them excellent. One was a geometry bug we fixed; the other was a shape that cannot be made to work, so we removed it rather than ship a button that quietly produces a broken code.

Nothing. There is no account, no email capture, no free trial that turns into a subscription, and no feature held back behind a paywall.

The AI features run on a shared quota, which is why they are rate-limited. If a lot of people use them at once you may occasionally be asked to wait a minute. The terms for all of this are on the terms page, and what happens to your data on the privacy page.
