Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
The og:
or Open Graph meta tags are the standard metadata format across all social media. This is different from Google’s meta tags which show in search results.
I’ve also checked your site and it seems that you have already set up your meta title and description, but Google still shows different results. You can also check your site here that your meta title and description are already set: https://www.heymeta.com/
In this case, ensure that this is the setting in the Schema tab if the Schema Markup module is enabled on your website:

To reiterate, the Schema title must show %seo_title%
and the description should show %seo_description%
– this will ensure your SEO title and SEO Description that you set up via Rank Math can also be used for your Schema details.
You must check if Google has seen the changes already or not.
For that, please check when the Google cache was updated for that page:
a. 
b. 
If the cache date is from before adding the new meta description, then you just have to wait for Google to re-crawl and re-index the page with the new info. If the date is after you made the changes, then you just have to wait it out and there is no further input needed from your end.
To remove all the OpenGraph and Twitter tags on the head section of your pages, add this filter on your theme’s functions.php file:
/**
* Hook to remove og:tags
*/
add_action( 'rank_math/head', function() {
remove_all_actions( 'rank_math/opengraph/facebook' );
remove_all_actions( 'rank_math/opengraph/twitter' );
});
I hope that helps. Thank you, and please don’t hesitate to contact us if you need further assistance.
