How often site owners write rules for Poseidon Research's tokens, from our own robots.txt study of the Tranco top 10,000:
| Token | Files naming it | Files blocking it |
|---|---|---|
Poseidon Research Crawler | 46 (0.8%) | Not measured |
A Poseidon Research token can be blocked without being named, through a User-agent: * group with Disallow: /, so its blocking share can be higher than its naming share.
All counts come from 5,583 valid files fetched October 20, 2026.
A robots.txt file cannot say "Poseidon Research"; it can only name Poseidon Research's tokens, one group at a time. With a single token, one group is the whole policy.
# One token controls everything Poseidon Research fetches through it

User-agent: *.* group, so copy any Disallow lines you still want it to obey.User-agent: Poseidon Research block all of Poseidon Research's crawlers?No. robots.txt matches crawler tokens, not company names. Use the token Poseidon Research Crawler.
No. Each token is read separately. Blocking one leaves the rest following whatever group applies to them.
A one-paragraph brief for every Poseidon Research token in our database, covering what it does, how it treats robots.txt and how often large sites write rules for it:
Poseidon Research Crawler, Tier 6): a utility crawler that harvests pages for a dataset or data product. Rated safe. Poseidon Research Crawler's operator does not clearly document how it treats robots.txt. Write the Poseidon Research Crawler rule anyway, then confirm in your logs that its requests stop. 0.8% of top-site robots.txt files name it.The errors we see most often with Poseidon Research's crawlers in the files and firewalls we test:
All three hide inside a file that looks correct, so check Poseidon Research's crawlers from outside after every change.
Everything below comes from the AI Crawler Check bot database and our two most recent robots.txt scans of the Tranco top 10,000, not from Poseidon Research's marketing. Poseidon Research has one token in our database, so the whole picture fits in one place.
Poseidon Research Crawler in our recordsWe first recorded Poseidon Research Crawler on March 17, 2026. We could not find a page where Poseidon Research names it, so treat the token as reported rather than documented. Poseidon Research Crawler is outside our tracked token set, but 46 of 5,583 top-site files already name it, which is enough to show owners treat it as a real crawler.
Among the 39 data scrapers in our database, Poseidon Research Crawler sits 31th by priority (Tier 6), level with Amazon Kendra, ApifyBot, Barkrowler, BLEXBot. 29 of the 39 share its safe rating. Other operators with a crawler that harvests pages for a dataset or data product: FirecrawlAgent (Firecrawl, Tier 2), iaskspider (iAsk, Tier 2), NovaAct (Amazon, Tier 2), CloudflareBrowserRenderingCrawler (Cloudflare, Tier 3), Amazon Kendra (Amazon, Tier 6). A policy for Poseidon Research Crawler is usually a policy for these too.
Poseidon Research CrawlerTeams that review crawlers once a quarter keep one short entry per token, so anyone can see why a rule exists and when it was last checked. Filled in from our data, the Poseidon Research Crawler entry reads:
User-agent: Poseidon Research Crawler
Allow: /
Paste the line into the validator with one of your own URLs before it goes live. Revisit the Poseidon Research Crawler entry once a quarter, or when Poseidon Research publishes a new token next to it.
Poseidon Research Crawler on your own siteBecause Poseidon Research runs only Poseidon Research Crawler in our records, one check covers the whole operator. Search your access logs for the string Poseidon Research Crawler over the last 30 days, note how many requests it made and which paths it asked for, then compare that with what your robots.txt allows. Poseidon Research publishes no page about the crawler that we could find, so judge it by the requests you actually see rather than by its name. A Tier 6 crawler rated safe rarely needs more than a quarterly look, and our log checker does the counting for you.
From our robots.txt study of the Tranco top 10,000 (5,583 valid files, fetched October 20, 2026):
None of the tokens for Poseidon Research's crawlers is tracked by name in our study. For scale, 20.1% of top-site files block at least one AI training crawler and 4.3% refuse every unnamed crawler with User-agent: * and Disallow: /, which would catch Poseidon Research's crawlers too.
Poseidon Research Crawler, add Disallow lines for the paths to keep private and Allow lines for exceptions. The longest matching rule wins.User-agent group per decision and repeat any shared rules inside it.This rule covers the single crawler Poseidon Research operates. Add it to the robots.txt file at the root of your domain.
These Poseidon Research rules ask; they do not enforce. If a Poseidon Research token ignores them, block it at the server or CDN. Paths are case-sensitive, and each rule matches the token, not the full user-agent string.
