facebook.com and google.com
Measured takeaway
facebook.com's robots.txt disallows every crawler; google.com's does not.
Measured in Botfy's 2026-09-07 publication.At a glance
A difference appears only when both sites have comparable evidence. Unavailable or unresolved observations remain incomplete.
| Evidence | facebook.com | google.com |
|---|---|---|
| robots.txt | Served and parsed | Served and parsed |
| Google crawl posture | Blocked | Open |
| Unnamed crawler fallback | Blocked the wildcard (*) group disallows everything, so they are blocked without being named | Partly Restricted they inherit the wildcard (*) group's rules |
| Base /llms.txt | Related file observed at /ai.txt; /llms.txt not established | Not found when probed |
Treatment by purpose
Only resolved blocked, allowed, or mixed states count as a policy agreement or difference. Unnamed agents still inherit each site's wildcard rules.
| Declared purpose | facebook.com | google.com |
|---|---|---|
| Model training | Mixed | Not explicitly addressed |
| AI search | Mixed | Not explicitly addressed |
| Live assistant fetch | Mixed | Not explicitly addressed |
| Opt-out directives | Mixed | Not explicitly addressed |
| Ambiguous / undocumented | Blocked | Not explicitly addressed |
Named agents
Measured differences appear first. “Not explicitly addressed” is not the same as allowed; the site's wildcard fallback governs that crawler.
| Agent | facebook.com | google.com |
|---|---|---|
| GPTBot OpenAI | Partly blocked | Not explicitly addressed |
| ClaudeBot Anthropic | Partly blocked | Not explicitly addressed |
| Applebot Apple | Partly blocked | Not explicitly addressed |
| PerplexityBot Perplexity | Partly blocked | Not explicitly addressed |
| PetalBot Huawei | Blocked | Not explicitly addressed |
| Amazonbot Amazon | Partly blocked | Not explicitly addressed |
| Google-Extended Google | Partly blocked | Not explicitly addressed |
| Applebot-Extended Apple | Partly blocked | Not explicitly addressed |

How each site compares with its own rank peers
The sites may belong to different rank bands. Each percentage keeps its own population and denominator; Botfy does not subtract rates from unlike cohorts.

How this comparison is measured
Both sites use Botfy's latest published observations. A missing fetch, unresolved agent verdict, and measured absence are different states. Peer percentages use each site's exclusive Tranco rank band and print their own denominator. Populations, sources, and limits →
