What do the bots actually get?

Questions

Does bizjournals.com block GPTBot?

Yes. bizjournals.com’s robots.txt disallows GPTBot from the whole site (line 57: Disallow: /). GPTBot is OpenAI’s crawler for training data; blocking it doesn’t affect ChatGPT search, which uses OAI-SearchBot. Checked 9 November 2026.

Does bizjournals.com block Google-Extended?

Yes. bizjournals.com’s robots.txt disallows Google-Extended from the whole site (line 54: Disallow: /). Google-Extended is the token that controls whether Google may use pages for Gemini training and grounding; it doesn’t affect Google Search. Checked 9 November 2026.

Does bizjournals.com block PerplexityBot?

No. bizjournals.com’s robots.txt lets PerplexityBot crawl the site. PerplexityBot is the crawler that indexes pages for Perplexity’s answers. Checked 9 November 2026.

Can ChatGPT search find bizjournals.com?

Yes. bizjournals.com’s robots.txt lets OAI-SearchBot crawl the site. OAI-SearchBot is the crawler behind ChatGPT search; blocking it keeps the site out of ChatGPT’s search answers. Checked 9 November 2026.
