Hello,
Thank you for reaching out with your question about adding a custom meta field in the Rank Math plugin. 
Regarding the ‘keywords’ meta field, it’s important to note that search engines like Google no longer use the keywords meta tag as a ranking signal. However, if you still wish to include it for any reason, you can follow these steps:
- 
Install and activate the Rank Math plugin on your WordPress site. If you haven’t installed it yet, you can find detailed instructions in the Rank Math setup guide.
 
- 
Once Rank Math is activated, you can include the keywords meta tag by using a filter in your theme’s functions.php or rank-math.php file. You can create a rank-math.php file in the path /wp-content/themes/theme-name/rank-math.php using FTP or cPanel File Manager.
 
- 
Open your theme’s functions.php or rank-math.php file and add the following code snippet:
 
/**
 * Add .
 */
add_filter( 'rank_math/frontend/show_keywords', '__return_true');
- Save the changes to your file.
 
By adding this filter, Rank Math will display the keywords meta tag on your website.
If you have any further questions or need assistance, feel free to ask.
You can also refer to the Rank Math Keywords Meta Tag guide for more information.
If you need further assistance or have any other questions, please let us know.

		Hello, 
Thank you for contacting us and bringing your concern to our attention.
Please note that Google does not honor meta keywords for quite a long now so we never added them to the plugin.
You can read more about that here:
https://webmasters.googleblog.com/2009/09/google-does-not-use-keywords-meta-tag.html
​
​However, if you still want to use the focus keyword set within Rank Math as a meta keyword then you can add the following filter on your website:
add_filter( 'rank_math/frontend/show_keywords', '__return_true');
Here’s how you can add filter/hook to your WordPress site: https://rankmath.com/kb/wordpress-hooks-actions-filters/
Hope that helps and please don’t hesitate to let us know if you have any other questions.
Thank you.
