fnp.de: AI crawler policy in robots.txt
robots.txt as fetched on 2026-10-10: fnp.de disallows 14 of 22 AI and search crawlers from the site root: GPTBot, ClaudeBot, Google-Extended, CCBot, meta-externalagent, Bytespider, Applebot-Extended, Amazonbot, cohere-ai, Diffbot, omgili, Timpibot, DuckAssistBot, meta-externalfetcher. That includes crawlers behind AI answers (DuckAssistBot, meta-externalfetcher).
The file refuses training crawlers and also some crawlers that power AI answers, so the site is likely to be missing from AI citations and the referral traffic that follows.
This reports what the file asks. It does not show whether a crawler can actually reach the site: many sites also block crawlers at their CDN or firewall, and some crawlers ignore robots.txt.
Training crawlers
Disallowing these keeps a site's content out of future model training. It does not remove what was already collected.
| Crawler | Operator | Status | How the file treats it |
|---|---|---|---|
| GPTBot | OpenAI | disallowed | covered by the default rule |
| ClaudeBot | Anthropic | disallowed | covered by the default rule |
| Google-Extended | disallowed | covered by the default rule | |
| CCBot | Common Crawl | disallowed | covered by the default rule |
| meta-externalagent | Meta | disallowed | covered by the default rule |
| Bytespider | ByteDance | disallowed | covered by the default rule |
| Applebot-Extended | Apple | disallowed | covered by the default rule |
| Amazonbot | Amazon | disallowed | covered by the default rule |
| cohere-ai | Cohere | disallowed | covered by the default rule |
| Diffbot | Diffbot | disallowed | covered by the default rule |
| omgili | Webz.io | disallowed | covered by the default rule |
| Timpibot | Timpi | disallowed | covered by the default rule |
Search and citation crawlers
These feed AI answer engines that cite and link their sources. Disallowing them can take a site out of AI answers and out of the referral traffic that comes with them.
| Crawler | Operator | Status | How the file treats it |
|---|---|---|---|
| OAI-SearchBot | OpenAI | not disallowed | named in the file |
| PerplexityBot | Perplexity | not disallowed | named in the file |
| Claude-SearchBot | Anthropic | not disallowed | named in the file |
| DuckAssistBot | DuckDuckGo | disallowed | covered by the default rule |
User-action fetchers
These fetch a page live when a person asks an assistant about it. Disallowing them stops the assistant reading the page for that person.
| Crawler | Operator | Status | How the file treats it |
|---|---|---|---|
| ChatGPT-User | OpenAI | not disallowed | named in the file |
| Perplexity-User | Perplexity | not disallowed | named in the file |
| Claude-User | Anthropic | not disallowed | named in the file |
| meta-externalfetcher | Meta | disallowed | covered by the default rule |
