3 of 14 AI agents get the full page at https://healthline.com/. Checked 2026-09-25 09:33 UTC.
healthline.com scores 57 out of 100 for machine visibility, number 42 of the 100 content publishers checked on 2026-09-25. 3 of 14 AI agents receive the full page: 1 of 8 training crawlers, 1 of 3 AI search indexes and 1 of 3 assistant fetchers. All 7 refusals are written in robots.txt, which is the transparent way to do it. The pattern is "cite me, don't train on me": 7 of 8 training crawlers are refused while 2 of 6 search and assistant fetchers get through. Googlebot itself is partial: Different content than humans receive. There is no llms.txt.

- infoTraining blocked, citation allowedTraining crawlers are refused while search and assistant fetches get through. This is the common "cite me, don't train on me" posture.

- lowNo llms.txtOptional, but a short curated index at /llms.txt is the cheapest way to tell assistants what matters on this site.
- infoGoogle-Extended not listedYou block other training crawlers but Gemini training via Google-Extended is still allowed. Add it to the same group if the policy is meant to be even-handed.
- infoCanonical points elsewhereCanonical is https://www.healthline.com/. Indexes will credit that URL, not this one.
