What is Crawlson?
Crawlson is a web crawler bot that indexes content for the Crawlson search engine by systematically browsing and analyzing web pages. Agent Analytics can track when it visits your website.

Expected Behavior
Crawlson crawls on a schedule set by algorithms, not a calendar. Expect visit frequency to track your site's popularity, how often your content changes, and your domain authority. It throttles itself to avoid loading your server and honors crawl rules better than almost any other category of bot.

Disallow: /Frequently Asked Questions
Should I Block Crawlson?
No, unless you want your pages out of search results. Crawlson feeds a search engine index, and blocking it erases your visibility and organic traffic from that engine. This is the one category almost every website should allow. Almost none of the top websites we track have robots.txt rules for Crawlson right now.
Does Crawlson Respect Robots.txt?
Yes. Crawlson is expected to honor robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms Crawlson actually honors it.
Does Crawlson Access Private Content?
No. Crawlson indexes public pages only and does not sign in anywhere. Watch for accidentally public content though, because anything reachable without a login can end up in search results.
Why Is Crawlson Visiting My Website?
Crawlson is keeping its search index current. Links, sitemaps, or direct submission brought it to your site, and it comes back at a rate tuned to how often your content changes and how popular your site is.
How Can I Tell if Crawlson Is Visiting My Website?
Agent Analytics tracks Crawlson visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "Crawlson". Look for steady recurring visits spread across your site. Keep in mind that Crawlson doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
