Frequently Asked Questions
What Traffic Patterns Should I Expect From Yahoo! Slurp?
Yahoo! Slurp follows an algorithmic schedule shaped by your site's popularity, update cadence, and domain authority. It generally spreads requests across recurring crawl passes, throttles itself to limit server load, and respects crawl rules more reliably than most other bots.
Does Yahoo! Slurp Follow Robots.txt Rules?
Yahoo! Slurp is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Yahoo! Slurp respects it.
Is Yahoo! Slurp Used for AI Model Training?
Not ordinarily. Yahoo! Slurp is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Yahoo! Slurp Affect AI Search or Citations?
Blocking Yahoo! Slurp can remove your pages from the search engine it supplies. That may also affect AI products that rely on the same index, but it does not directly control unrelated AI search services.
Does Yahoo! Slurp Access Private Content?
No special access. Yahoo! Slurp can reach only content available to anonymous visitors and does not sign in. Make sure sensitive content is not public by mistake.
How Can I Verify a Request From Yahoo! Slurp?
Agent Analytics tracks Yahoo! Slurp visits in real time. You can also check your server logs for requests whose user-agent string contains "Yahoo! Slurp". Look for recurring passes that revisit changed pages and discover new ones. Because Yahoo! Slurp does not publish a verification method, any client can claim its identity and a log match is only a clue.
