What do the bots actually get?

This page reads robots.txt, which states what houzz.com asks of crawlers. A firewall or CDN can still refuse a bot that robots.txt allows. The live check requests the page as each bot and shows the status it gets.

History

Questions

Does houzz.com block GPTBot?

Partly. houzz.com’s robots.txt keeps GPTBot out of some paths, such as /ad/*, and lets it crawl the rest. GPTBot is OpenAI’s crawler for training data; blocking it doesn’t affect ChatGPT search, which uses OAI-SearchBot. Checked 9 November 2026.

Does houzz.com block ClaudeBot?

Partly. houzz.com’s robots.txt keeps ClaudeBot out of some paths, such as /ad/*, and lets it crawl the rest. ClaudeBot is Anthropic’s crawler for training data. Checked 9 November 2026.

Does houzz.com block Google-Extended?

Partly. houzz.com’s robots.txt keeps Google-Extended out of some paths, such as /ad/*, and lets it crawl the rest. 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 houzz.com block PerplexityBot?

Partly. houzz.com’s robots.txt keeps PerplexityBot out of some paths, such as /ad/*, and lets it crawl the rest. PerplexityBot is the crawler that indexes pages for Perplexity’s answers. Checked 9 November 2026.

Can ChatGPT search find houzz.com?

Partly. houzz.com’s robots.txt keeps OAI-SearchBot out of some paths, such as /ad/*, and lets it crawl the rest. OAI-SearchBot is the crawler behind ChatGPT search; blocking it keeps the site out of ChatGPT’s search answers. Checked 9 November 2026.
