Rule site.llms-txt.optional-section-missing
Add an Optional section to /llms.txt
site.llms-txt.optional-section-missing is a check in Crawlmind's site audit that grades low-impact issues of this kind. This page explains why the rule matters and the exact fix.
Why it matters
The llmstxt.org spec defines `## Optional` as the section for supplementary URLs the engine should consider but not treat as canonical. Without it, AI engines have no signal for "this is supporting content vs. core content" and may either weight off-host links incorrectly or skip them entirely.
The fix
```markdown
## Core
- [Pricing](https://example.com/pricing)
- [Docs](https://example.com/docs)
## Optional
- [Engineering blog](https://blog.example.com)
- [Status page](https://status.example.com)
- [GitHub organisation](https://github.com/example)
```
Reasonable Optional candidates: blogs, changelogs, status pages, GitHub orgs, podcast feeds, community forums, off-host documentation.
