This is a fork of the original Google SEO plugin by frostschutz. It provides support for PHP 8, mostly by fixing warnings that occur under PHP 8. We forked it with frostschutz's permission: he doesn't have time to work on it. We currently have no plans to extend it in any other way than by fixing bugs, especially those related to PHP 8. For details, see the original Extend page for the plugin at the supplied link.
