Frequently Asked Questions

Common questions about Link Checker

A reason if the Link Checker could not access your site could be that the crawler of the Link Checker is blocked by your hosting provider. I have observed this issue especially with free and really cheap hosting providers. Some block crawlers (and regular visitors) already after five fast sequential requests. The issue could be fixed by whitelisting the IP of the crawler. However, I think this option is not available for the affected hosting services. Alternatively it is possible to use the crawl-delay directive in your robots.txt to set the delay between two requests.

The Link Checker uses a custom user-agent group named MB-SiteCrawler. This allows you a fine grained control of which pages are checked. If you do not define a group for the custom user-agent in your robots.txt file, the default set in the * group apply.

No, the Link Checker needs to crawl your website and the generator has no access to you local network.

In the most cases this is due to the fact that you have set a large value for the crawl-delay directive in your robots.txt file. Some hosters also add the crawl-delay directive automatically to your robots.txt file. The crawl-delay defines the time in seconds between to requests of the crawler.
