What is Yahoo! Slurp?
Yahoo! Slurp crawls and indexes web page information for Yahoo Search. Yahoo identifies it by the Slurp product token, while access logs usually show that token inside a longer browser-style user agent.
Yahoo notes that some of its search results come from partners. Its own Slurp help page still tells site owners to allow Slurp if they want pages considered for Yahoo Mobile Search. Blocking the bot therefore has a specific Yahoo search consequence, but it should not be described as removing a site from every result Yahoo serves.
The documented full user agent is Mozilla/5.0 (compatible; Yahoo! Slurp; http://help.yahoo.com/help/us/ysearch/slurp). Cloudflare's bot directory records a variant with an extra sieve-gq1 suffix. Rules and log filters should match Slurp rather than depend on that trailing build text.
Slurp follows the Robots Exclusion Standard. Yahoo says it uses the first robots record whose user-agent value contains Slurp; if none exists, it falls back to the first wildcard record. The crawler also supports a crawl-delay directive for sites that need fewer requests.
This is a conventional search indexing crawler. Neither the supplied record nor Yahoo's crawler documentation assigns Slurp a role in generative answers or model training. A Slurp visit shows that Yahoo Search is fetching a page, not that the page has entered an AI training corpus.
Cloudflare's directory describes Slurp in the past tense and links to an older Yahoo help URL, while Yahoo's live help center continues to document the crawler and its mobile search use. The Cloudflare record supplies no signature key directory, and this entry has no verified IP range. A matching user agent is useful for classification but cannot prove that Yahoo sent the request.
