# Crawl-delay is honoured by AhrefsBot and SemrushBot (Semrush caps it at 10s). # GPTBot does not document or honour Crawl-delay - OpenAI's bot docs list no # rate-limit directive - so slowing it needs Disallow or an edge rule instead. # Note: a bot matching its own User-agent group ignores the * group entirely, # so each block below repeats the rules it still needs.
