What you are probably seeing

You notice your site is blocked to GPTBot in your robots.txt file but you see no correlation between this and your citation loss in Google Search Console or analytics.

Your audit shows you block GPTBot while leaving OAI-SearchBot open, yet your citation counts from ChatGPT remain low or disappear after your block is active.

Why it happens

ChatGPT uses two separate bots for different purposes: GPTBot is for training data, while OAI-SearchBot is for live retrieval and citations.

Many operators block GPTBot to prevent training on their content but forget that OAI-SearchBot is the crawler responsible for fetching current information to answer user queries with citations.

What changed recently

Step by step

1. Review your robots.txt file to confirm which user-agents are currently blocked or allowed.

2. Check the documentation for OAI-SearchBot to understand its specific role in retrieval-augmented generation.

3. Decide your strategy: allow OAI-SearchBot if you want citations, or block both if you want to exclude your site from ChatGPT entirely.

4. Update your robots.txt file to reflect your decision for both GPTBot and OAI-SearchBot.

5. Monitor your citation metrics in ChatGPT and search logs over the next few days to see if visibility changes.
