Broken Links Repair Plugin automatically disables the 404 links detected by the Hexometer crawler in your WordPress content, until you will fix or change them. In other words the links become "not clickable", so your visitors and search engine crawlers will not get the 404 error message by clicking on them.
Currently, free accounts are limited up to 10,000 URLs, if your website has more URLs then you have to upgrade to the appropriate package, otherwise, the system will scan only the mentioned amount of links.
Yes! Your content is absolutely secure. We do not edit your content, the plugin disables the broken link's "a href" tag from the content before the page loads. And you can switch ON/OFF anytime from your plugin page.
