The August 2026 crawl, parsed for a robots.txt rule naming this user-agent, on the same 0.1% sample of the corpus as every other figure on this site — 15,009 sites. It used to be measured on the whole corpus and this note used to say so; it moved to the monthly sample when the axis gained a series, so it now carries the same margin as everything else.

What Applebot-Extended actually does
Run by Apple. Controls whether your content trains Apple’s generative models. Separate from Applebot, which indexes for Siri and Spotlight and is not affected. Blocking it costs you no traffic: this crawler does not send anyone your way.
What to write in your robots.txt
Put the rule in its own group. A Disallow under User-agent: * predates these agents and several of them do not treat it as applying to them — which is also why this census does not count it.
