13 of 14 AI agents get the full page at https://vungle.com/. Checked 2026-09-25 09:18 UTC.
vungle.com scores 87 out of 100 for machine visibility, number 42 of the 100 most visited websites checked on 2026-09-25. 13 of 14 AI agents receive the full page: 7 of 8 training crawlers, 3 of 3 AI search indexes and 3 of 3 assistant fetchers. The one refusal happens 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": 1 of 8 training crawlers are refused while 6 of 6 search and assistant fetchers get through. Bytespider received a bot-management challenge instead of the page. There is no llms.txt.

Gaps
- medium1 of 14 AI agents are blockedBytespider: Bot challenge served (HTTP 403)
- 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.
- mediumBot-management challenge served to crawlersBytespider received an interstitial instead of the page. A robots.txt rule is an honest block. A challenge hides the page without saying so.
- 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://liftoff.ai/. Indexes will credit that URL, not this one.
