AI2Bot-DeepResearchEval
AI2Bot-DeepResearchEval is a live-fetch agent operated by AI2. It does not crawl the web on a schedule. It hits your site only when an end-user asks the underlying AI a question that requires fresh information from a specific page.
Traffic is bursty and unpredictable. A single trending topic can send hundreds of AI2Bot-DeepResearchEval requests in an hour, then nothing for days. Each request typically reads one or two pages, not your whole site.
Allowing AI2Bot-DeepResearchEval is how your content becomes part of AI2's answers. Blocking it means users asking that AI about your topic will be answered using someone else's content instead.

Should I let AI2Bot-DeepResearchEval through?
In most cases, yes. Live-fetch agents drive citations inside AI answers. Allowing keeps your content in the conversation. If volume gets noisy, rate-limit it before you block it outright.
Does blocking AI2Bot-DeepResearchEval affect my Google rankings?
No. AI2Bot-DeepResearchEval fetches a page only when a user is actively asking AI2 a question. It has nothing to do with how Google or Bing rank you. The cost of blocking is that AI2 can't quote your content in its answer.
How do I confirm a request is really from AI2Bot-DeepResearchEval?
Look at the User-Agent header in your access logs and match it against the strings listed above. Worth knowing that the User-Agent is easy to fake, so this check tells you "the traffic claims to be AI2Bot-DeepResearchEval", not "the traffic is genuinely AI2Bot-DeepResearchEval". If you need stronger guarantees, look for a reverse-DNS check or wait for AI2 to publish IP ranges.
Does a AI2Bot-DeepResearchEval visit count as a real user visit?
Sort of. There is a human asking AI2 a question on the other end, but they never load your page in their own browser. They see whatever AI2 quotes back, usually a snippet plus a citation link. Count it as upstream attention rather than as a session.
How is AI2Bot-DeepResearchEval different from AI2's other bots?
AI2 splits work across multiple user-agents so site owners can decide on each one independently. Training crawlers, live-fetch agents, search indexers, and agentic browsers each get their own name. Worth scanning the rest of the AI2 family above to see which ones actually matter for your site.
What's the cleanest way to control AI2Bot-DeepResearchEval?
Two layers. Robots.txt for the polite crawlers that read it, and rules at your CDN or edge for the ones that don't. Rankly's Agent Experience handles both from a single config, so you can allow, block, rate-limit, or serve a stripped-down version per bot. Agent Analytics handles the observation half so you know which bots are actually worth a rule.
