“Read us” is what each read on tidekeeper.eu in the last 30 days, as tidekeeper counts its own site. “Address list”: its owner publishes the addresses it reads from, and tidekeeper checks every read against them.

Search, previews and the rest

A bot that is not here is still left out of every figure, as a crawler, by its User-Agent and its behaviour; it is only not named. The free tool Can AI read your site? reads your robots.txt as each of these would.
