What is lyonl-crawler?

lyonl-crawler 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.

lyonl-crawler 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 lyonl-crawler respects it.

Not ordinarily. lyonl-crawler is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.

Blocking lyonl-crawler 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.

No special access. lyonl-crawler can reach only content available to anonymous visitors and does not sign in. Make sure sensitive content is not public by mistake.

Agent Analytics tracks lyonl-crawler visits in real time. You can also check your server logs for requests whose user-agent string contains "lyonl-crawler". Look for recurring passes that revisit changed pages and discover new ones. Because lyonl-crawler does not publish a verification method, any client can claim its identity and a log match is only a clue.

Lyonl operates separate agents for different purposes, so each agent should be evaluated and controlled independently.
