Our server in London requests the page you enter once, the same way a search engine first does: the HTML as delivered, before any script runs. It also asks for the plain http:// version of the address, the site’s robots.txt and its sitemap. That is four requests to your site in all.
Every finding says what was measured. Found means it is there, and we quote it. Missing is only used when the HTML proves it is absent. Could not check means the page could not settle it: a form drawn by a script, a page assembled in the browser, a page too large to read in full, or reviews shown as pictures would all be invisible to this kind of check, so we mark them that way. Worth a look means it is there but may need attention, and Measured is a plain measurement with no verdict.
There is no overall score. The checks are separate facts of very different weight, and one number out of a hundred would suggest a precision they do not have.
Every explanation is fixed wording, written in advance for that check and that result.
The results are not stored. Nothing is sent to us unless you ask for the full report below.
