Hreflang Tag Checker is designed to automate the process of checking the implementation of hreflang tags on a site. The tool takes readings of the hreflang tags of the URL and then crawls them to determine if they point to your current URL. This saves valuable time when it comes to evaluating your site's language targeting and hreflang architecture, allowing you to get a quick and reliable picture of your site's optimization status for international organic search.
