Hello,
Thank you for contacting Rank Math today.
Rank Math does not add the meta keyword tag to the page source which I believe this tool is using to detect focus keywords.
We do not do this because search engines stopped using this tag to detect keywords a few years back.
It is however still possible to enable this feature by adding the following snippet of code to your theme’s functions.php file:
/**
* Add <meta name="keywords" content="focus keywords">.
*/
add_filter( 'rank_math/frontend/show_keywords', '__return_true');
Looking forward to helping you. Thank you.
