Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
We use focus keywords to measure the internal SEO score, we do not add them to the page source.
You can read more about it here:
https://rankmath.com/kb/what-is-a-focus-keyword/
​However, you can use the focus keyword set within Rank Math as a meta keyword for your posts/pages/products using this filter in your theme’s functions.php
file:
/**
* Add <meta name="keywords" content="focus keywords">.
*/
add_filter( 'rank_math/frontend/show_keywords', '__return_true');
Here is a guide you can follow to add the filter:

Hope that helps. If you have any further questions, please let us know.
​
​Thank you.
Oh that’s good to know, this will be very helpful. Thank you!
