Two different webs
6 of 14 AI agents get the full page at https://springer.com/. Checked 2026-09-25 09:19 UTC.
springer.com scores 64 out of 100 for machine visibility, number 74 of the 100 most visited websites checked on 2026-09-25. 6 of 14 AI agents receive the full page: 2 of 8 training crawlers, 2 of 3 AI search indexes and 2 of 3 assistant fetchers. All 8 refusals happen at the HTTP level with no matching robots.txt rule, so a crawler cannot tell the block is deliberate. The pattern is "cite me, don't train on me": 6 of 8 training crawlers are refused while 4 of 6 search and assistant fetchers get through. There is no llms.txt.

- lowVery little text in the raw HTML37 words. Thin for both humans and machines.
- 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.
