Link Checker Pro

How the crawl checks your WordPress site

Link Checker Pro sends your website URL and the fact that it uses WordPress to a server operated by the add-on developer. That server crawls the site like a regular user, checks internal and external URLs, then returns a list of broken links and redirects. The external service handles the crawl work, keeping the computation on your website low. The link checker works with WordPress extensions out of the box, works with Polylang, and may also work with WPML.

The crawler respects robots.txt, including the crawl-delay directive. A hosting provider may block it, preventing access to the site. The crawler also cannot reach a local development site on your private network.

Pro checks and recurring reviews

Link Checker Pro checks embedded internal and external images and tests whether embedded YouTube videos are available. You can schedule a check once a day and receive a summary by email. Export results as CSV for spreadsheet review or sharing. Form login support lets the crawler check protected pages, such as membership areas. Results are saved on the Link Checker server, so they can be fetched more than once, including by various customers or browsers, without running another check.

The free version checks up to 500 URLs. Image and video checks, CSV export, scheduling, and form login support are not included in that version.

Installation and crawl access

Install and activate the extension in WordPress, open Link Checker from the sidebar, and choose “Check your website” to start a crawl. For protected pages, provide the required form login details. You can enable the daily schedule and email summary for recurring checks, then review the results list or export it as a CSV file.

The stated requirements are WordPress 4.7 or newer and PHP 5.6 or newer. Check that your hosting provider allows the external crawler to access the site and that your robots.txt rules allow the pages you want it to crawl.
