The search crawler, education crawler, and user-initiated fetcher are not the same thing. The robots.txt content expresses usage preference; WAF, auth, and server security are separate layers. Purpose-based policies should be created for OAI-SearchBot, GPTBot, Google-Extended, Bingbot, and PerplexityBot.

Search crawler ≠ training crawler
robots.txt ≠ authentication
User-Agent ≠ verified bot
Allow rules need IP verification

Record brand, query, platform, source URL and measurement date in standard format.
Check robots, WAF, canonical, index, structured data and HTTP responses.
Do not interpret mention, citation, impression, referral and conversion values as the same metric.
Verify which hypothesis works with baseline, changelog, and remeasurement.
Do not use the robots.txt file as authentication or a firewall.
Meaning: Search visibility can be blocked by incorrect bot rule.
Possible cause: OAI-SearchBot/GPTBot or Googlebot/Google-Extended confusion.
Meaning: The attacker may attempt to access with the real bot name.
Possible cause: Trust only the header.
Meaning: Robots rules do not stop malicious clients.
Possible cause: The robots' voluntary protocol.
Meaning: Real crawler is blocked in the security layer.
Possible cause: Bot Fight Mode or custom rule.
Meaning: Crawler is hitting the rate-limit.
Possible cause: Excessive strict global limit.
Meaning: Google Search does not directly affect visibility.
Possible cause: Gemini education/grounding control token.
Meaning: These are the fetchers working with the user request.
Possible cause: Automatic crawler is not.
Meaning: Crawler IP ranges change, so access may be disrupted.
Possible cause: Static list has not been updated.

Googlebot Search for, control token for different Gemini uses for Google-Extended; Bingbot provides index access.
PerplexityBot and Perplexity-User have different purposes.
No. Technical feasibility, access, content quality, and measurement can be improved; citation and AI response depend on the dynamic systems of the platforms.
No. Crawl, index, canonical, content quality, and site reliability are the foundation of GEO work.
No. It is a community suggestion; Google Search explicitly states that it does not use it as a special visibility signal.
There is no special schema for Google AI features. Supported structured data must be used in a manner compatible with visible content.
No. Bot access only provides discovery and retrieval permission; source selection is not guaranteed.
AI impression, mention, citation, cited URL, referral, assisted conversion, and answer accuracy should be measured together.
There is no fixed duration. Crawl refresh, platform scope, content change, and user request vary accordingly.
We audit bot access, content, entity, citation and measurement processes for Google AI, ChatGPT Search, Bing Copilot and Perplexity. We do not guarantee exact citation or ranking.
