Why did LinkCheckerBot visit my page?

A LinkChecker.Pro user may be monitoring a backlink expected on that page. The crawler fetches the page so the service can check the link.

Does LinkCheckerBot respect robots.txt?

Yes. LinkChecker.Pro says it strictly follows robots.txt, and both the local record and Cloudflare mark it as compliant.

Can I slow LinkCheckerBot down without blocking it?

Yes. The operator says LinkCheckerBot honors a `Crawl-delay` directive in its robots.txt group. Set the delay to the minimum interval your server can accept.

What user agent does LinkCheckerBot send?

The documented value is `Mozilla/5.0 (compatible; LinkCheckerBot/2.0; +https://linkchecker.pro/robot/)`. The stable token for robots rules is `LinkCheckerBot`.

Does LinkCheckerBot affect AI answers or training?

No such role is documented. It checks backlinks for LinkChecker.Pro users and is not identified as an AI index or training collector.

LinkCheckerBot & AI Search: What to Know

What is LinkCheckerBot?

LinkCheckerBot is the crawler used by LinkChecker.Pro to monitor backlinks for its users. It visits a page where a customer expects a link so the service can check that backlink over time. The visit concerns the monitored page, even when the owner of that page is not the LinkChecker.Pro customer.

The crawler identifies itself as LinkCheckerBot/2.0 in a user agent that links to LinkChecker.Pro's robot page. That page describes it as a backlink checker rather than a general site-audit crawler. A user-agent match is useful for traffic classification but does not authenticate the sender.

LinkChecker.Pro says the crawler strictly follows robots.txt and also honors Crawl-delay. The bot record and Cloudflare agree that robots rules are respected. A webmaster can therefore set access and request frequency without blocking unrelated SEO tools.

Nothing in the operator's documentation connects LinkCheckerBot to AI search or model training. Allowing it helps a LinkChecker.Pro user verify a backlink; it does not submit the page to an AI assistant or a training dataset.

Indirectly relevant

Is LinkCheckerBot relevant for AI search?

Indirectly. LinkCheckerBot has no AI product of its own, but its output can end up in the systems that AI answers draw on.

LinkCheckerBot is an SEO auditing crawler. It has no direct effect on search rankings or AI answers, but the reports it feeds are used to fix crawlability and content issues that do affect how search and AI systems see your site.

How to handle LinkCheckerBot

Leave LinkCheckerBot available if you are comfortable with backlink checks on public pages. To stop the crawler across the site, use the exact token documented by the operator:

User-agent: LinkCheckerBot
Disallow: /

A path can be placed after Disallow: when only part of the site should be excluded. LinkChecker.Pro also documents this rate-control form:

User-agent: LinkCheckerBot
Crawl-delay: 10

Crawl-delay is not supported by every crawler, but LinkChecker.Pro specifically says LinkCheckerBot obeys it. Check access logs after changing the file, especially if a CDN caches robots.txt.

Examples

An agency monitors a client's backlink, causing LinkCheckerBot to revisit the publisher page where that link appears.
A documentation site permits backlink checks but adds a crawl delay after seeing several LinkCheckerBot requests close together.
A private community disallows LinkCheckerBot because backlink monitoring has no useful role on its public login pages.
