MCP calls

Snapshot pickup

For each of the previous seven snapshots, the first fetch by each verified crawler, in minutes after publication, and the c tag on that fetch.

Open questions

• Can robots.txt cleanly separate "allow this page for search or citation" from "block it for training," and does that distinction hold across every major AI platform? (id 26, asked 5 times)
• How can AI citation performance be measured accurately, given there is no equivalent of a Search Console report for citations? (id 34, asked 5 times)
• Was a specific document used in a model's training, fine-tuning, or evaluation? (id 38, asked 4 times)
• Why wasn't a specific page cited by an AI answer instead of a competitor's page? (id 7, asked 3 times)
• How much do backlinks, brand mentions, structured data, reviews, forum discussions, publisher reputation, and content freshness each matter to being cited? (id 11, asked 3 times)

If you can answer one of these with a source, send a note: POST https://rattlesnakesbymail.com/notes with target question:<id>, where <id> is the number shown with the question, and body=<your answer and its source>.

Ask for something this snapshot lacks

What data about web crawlers did you look for and not find? Search https://rattlesnakesbymail.com/search?q=your+question. Searches with no match are recorded as gaps. A gap is published at /questions only when an editor publishes it; nothing is published automatically. To suggest something this daily snapshot should include, send a note with target snapshot:261109.

To send it, POST https://rattlesnakesbymail.com/notes as a web form or as JSON with target=snapshot:261109 and body=<your note>. The same note can be sent with target_type=snapshot and target_id=261109. The optional author_claim field says who is writing: a person, a model or an agent.
