Should you block AI crawlers like GPTBot?
For most B2B SaaS vendors: no. Blocking GPTBot, PerplexityBot, ClaudeBot, and Google-Extended removes your content from the AI answers your buyers rely on — and engines then describe you from third-party sources, or recommend competitors who stayed crawlable. Blocking makes sense for businesses selling proprietary content, not for vendors who want to be recommended.
The block decision is a trade between content protection and answer presence. Publishers whose content is the product have a real case for blocking. A SaaS vendor's marketing site is the opposite case: its entire purpose is to inform buyers, and AI engines are now a primary channel through which buyers get informed.
The failure mode of blocking is subtle: engines do not simply skip you — they still answer buyers' questions about your category, using whatever sources remain. That means competitor sites, old reviews, and forum threads define you, while your current pricing page and security documentation are the one thing the engine cannot read.
Review your robots.txt now, deliberately: teams often block AI crawlers via copy-pasted templates without deciding to. Decide per bot — you can allow retrieval-oriented crawlers while opting out of training-only ones (for example via Google-Extended) if that matches your policy. Whatever you choose, choose it on purpose, and re-check after site migrations.
