Yahoo-FeedSeeker is a production-grade search engine crawler operated by Yahoo. It uses a distributed crawl infrastructure that respects crawl-delay directives, follows RFC 9309 (robots.txt) spec, and processes Sitemaps to prioritise fresh content. The user-agent string Yahoo-FeedSeeker must be whitelisted if your site uses rate-limiting or WAF rules. Blocking impact is Critical — Blocking removes you from search results.
<code>User-agent: Yahoo-FeedSeeker</code> — Matching is case-insensitive. Robots.txt is fetched from the root of each subdomain separately.
Yahoo-FeedSeeker is verifiable via reverse-DNS lookup on the crawling IP addresses. You can safely allow it unless you have a specific reason to block (e.g., AI training opt-out or SEO tool visibility).Understanding Yahoo-FeedSeeker's purpose helps you decide whether to allow or block it.
