Excerpt Length Set

Hello,

Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.

I see that you want to display Product Short Description in Meta Description and limit it to 155 characters.

Regarding the length of Meta Description, the ideal length for a meta description is 160 characters. Google generally truncates them to ~ 155–160 characters. It’s a good practice to keep meta descriptions long enough so that they’re descriptive and hence we recommend writing meta descriptions between 50-160 characters.

Check out this knowledge article for further details on this – https://rankmath.com/kb/ideal-meta-description-length/

In case you want to set a fixed limit of 155 characters, please add this code in your theme’s functions.php file – https://controlc.com/b7380088

Please note that the meta description length of 155 characters will not be visible in the editor. However, it will be applied and you can verify that in your page’s source code.

Hope this helps.

Looking forward to helping you. Thank you.

Hello,

Could you please add the below mentioned code to your theme’s functions.php file in order to set a fixed limit of 155 characters for the products?

add_filter( 'rank_math/frontend/description', function( $description ) {
	if(is_single() || is_product()){
		return wp_html_excerpt($description, 155);
	}
	return $description;
});

You can further modify this condition for pages and posts as well.

Hope this helps.

Looking forward to helping you.

Thank you.
