About these tools
Tools marked "Runs in your browser" process everything on your device; nothing you type is sent to us. Tools that check a URL send only that URL to our server, which requests the public page once and returns the results. We keep results in a short 10-minute cache and don't store your input beyond that.
The tools report what they find in the page or file. They don't estimate search volume, rankings, backlinks or traffic, and a syntax check is not the same as Google's own testing tools.
