Rule geo.ai_bots_blocked · Geo · 1 occurrence(s)

  • https://www.heiniger-ag.ch/ — robots.txt disallows AI search crawler(s): oai-searchbot (ChatGPT search). These fetch pages to cite in AI answers, so blocking them removes you from that citation pool. Allowing them is required for AI citations (though not a guarantee of them); blocking training bots like GPTBot/ClaudeBot is a separate, valid choice.
