длина «description»

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.

You can use this filter to extend the limit of description so your meta description templates will capture all of those words with a limit of 300:

add_filter('rank_math/frontend/description',function($description){
        $description=mb_substr(strip_tags($description),0,300);
        return $description;
});

The filter should be added to your active theme’s functions.php file. Here’s another way to apply the filter using the rankmath.php file:

Please note that the filter may not be visible while editing the posts as it only works when your posts load in a browser. You can check the published/saved post’s meta description via its source code.

You can also check the meta description using this tool:

I hope that helps.

Thank you.

Hello,

Unfortunately, that variable cannot be changed, the only way to limit how the meta description is displayed is through the filter code my colleague presented. The filter will limit the output of the meta description you entered on the SEO meta description field but not the output of the %excerpt%.

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
