Local Link Checker

This is a WordPress plugin from Plainwren. A site administrator runs a scan of links found in that site's own content. Checking links to other websites is off unless the administrator turns it on.

User agent

Each request uses this pattern, with the plugin version and the WordPress site's home URL:

LocalLinkChecker/<version> (+https://tools.plainwrenstudio.com/bots/local-link-checker/); <site URL>

The current plugin version is 0.1.1, so a typical string looks like LocalLinkChecker/0.1.1 (+https://tools.plainwrenstudio.com/bots/local-link-checker/); https://example.com/.

robots.txt

For links to other websites, the plugin fetches that host's /robots.txt once per scan and obeys the rules for the token LocalLinkChecker (or * if that group is not present). It does not request URLs that file disallows. If robots.txt cannot be read (for example a 4xx or 5xx response, or a timeout), the link is still checked. Internal links are not checked against robots.txt.

To opt out of these external checks, add rules like this to your robots.txt:

User-agent: LocalLinkChecker
Disallow: /

You can also block the user-agent token LocalLinkChecker at your server or firewall.

How often it requests

Requests to other websites are limited to at most one per second per host.
