See which AI crawlers
can access your site
A visual grid checks your robots.txt against 20 major crawlers — search engines, AI trainers, live browsing agents — and shows ✓ or ✗ for the current page URL.
20 bots. One grid.
Current page URL.
SEO Pulse reads your robots.txt and checks it against 20 known crawler user-agents — for the specific URL you're currently viewing, not just the root domain. A ✓ means the current URL is accessible to that bot. A ✗ means it's blocked.
Each bot card has a ⓘ tooltip showing the bot's owner, its type (search crawler, AI trainer, live browsing agent, AI training opt-out), and a plain-English explanation of what blocking it actually means for your site.
This matters because the distinctions are often misunderstood. Blocking Google-Extended doesn't affect Google Search. Blocking GPTBot doesn't stop ChatGPT from browsing your site. Blocking PerplexityBot doesn't protect your content from AI training. SEO Pulse explains each one so you can make informed decisions.
Every crawler, explained
SEO Pulse checks all of these against your robots.txt for the current page URL.
| User-agent | Owner | Type | What blocking means |
|---|---|---|---|
| Googlebot | Search crawler | Prevents Google from crawling your pages. Doesn't remove already-indexed pages but prevents updates. | |
| Google-Extended | AI training opt-out | Opts your content out of Gemini AI training. Does NOT affect Google Search indexing — Googlebot handles that separately. | |
| AdsBot-Google | Ad quality | Checks pages linked from Google Ads. Blocking may affect ad quality scores. | |
| Bingbot | Microsoft | Search crawler | Prevents Bing from crawling your pages. Also powers Microsoft Copilot answers. |
| GPTBot | OpenAI | AI training | Stops OpenAI collecting your content for model training. Does NOT affect ChatGPT live browsing. |
| ChatGPT-User | OpenAI | Live browsing | Fetches pages when a ChatGPT user asks it to browse the web. Not used for training. |
| OAI-SearchBot | OpenAI | AI search | Indexes pages for ChatGPT's search feature. Blocking removes your content from ChatGPT search. |
| ClaudeBot | Anthropic | AI training | Crawls for Claude AI training data. Blocking signals exclusion from future Claude training datasets. |
| Claude-User | Anthropic | Live browsing | Fetches pages for live Claude user queries. Not used for training. |
| Claude-SearchBot | Anthropic | AI search | Indexes pages for Claude search answers. Blocking may reduce your site's visibility in Claude. |
| PerplexityBot | Perplexity | AI search | Crawls for Perplexity search. Not a training crawler — Perplexity uses OpenAI/Meta models. |
| Applebot | Apple | Search crawler | Crawls for Siri, Spotlight, and Safari suggestions. |
| Applebot-Extended | Apple | AI training opt-out | Opts your content out of Apple Intelligence training. Does NOT affect Applebot search crawling. |
| meta-externalagent | Meta | AI training | Meta's primary crawler for AI model training and search across Meta's products. |
| FacebookBot | Meta | Fetches metadata for Facebook and Instagram link previews. Primarily for previews, not AI training. | |
| CCBot | Common Crawl | AI training | Non-profit web archive widely used to train language models — including many smaller AI labs. |
| Bytespider | ByteDance | AI training | ByteDance crawler for TikTok's AI systems. No official documentation. Widely reported to not consistently respect robots.txt. |
| Amazonbot | Amazon | AI crawler | Used to improve Alexa and Amazon AI features. Respects robots.txt. |
| DuckDuckBot | DuckDuckGo | Search crawler | Crawls pages for DuckDuckGo's search index. |
| YandexBot | Yandex | Search crawler | Crawls pages for Yandex Search. Relevant if you have Russian-language traffic. |
Distinctions that matter
Most robots.txt guides treat all AI bots the same. The reality is more nuanced — and the differences affect what you're actually protecting.
