How to customize default %%excerpt%% behavior by Yoast?

Hi @online0227

If you are using the %%excerpt%% variable, it should take the first 55 words from the content. There’s a specific excerpt field for posts, but for pages, it might just pull from the content itself and if you’re using a page builder, it’ll pull from the code.

In this case, we recommend either using a different snippet variable that would better suit the meta description template – https://yoast.com/help/list-available-snippet-variables-yoast-seo/

Hello, @mikes41720
This seems be not the answer I wanted to know.

I want Yoast to exclude html tag that has specific id I set (e.g. <div id=”yoast-exclude”>…</div>) from creating final meta description.

I checked up the page https://yoast.com/help/list-available-snippet-variables-yoast-seo/ but there seems to be no snippet variable doing such thing. Therefore I need to do regex thing to capture such html tag with specific id in yoast/wordpress backend and remove such tag with specific id before creating final meta desc to show, but I just don’t know which part of source code I should modify.

Thank you very much.

Hi,

It looks like you’re looking for the excerpt variable to ignore parts of code from the page content and just pull from the actual worded content. Are we understanding it correctly?

We’re not sure how to manipulate this particular variable to suit your needs, but you can review all of our available developer documentation here – https://developer.yoast.com/

You may want to try and use custom fields to generate some snippet variables so that it’ll fit your needs for the meta description output.

Hi,
I think this snippet can work to get an excerpt limited to 145 characters and create a yoast seo custom template variable.
It will work in: Yoast SEO -> Search Appearance -> Content Types -> “use at your own convenience”.

I hope it helps, and maybe is useful for this -> How to limit excerpt length?

/*
*
* Yoast SEO custom variable: excerpt
*/
// define the custom replacement callback
function get_myexcerpt() {
	// get the excerpt and limit to 145 characters
	$excerpt = get_the_excerpt();
	return substr($excerpt, 0, 145);
}

// define the action for register yoast_variable replacments
function pjlm_register_custom_yoast_variables() {
    wpseo_register_var_replacement( '%%myexcerpt%%', 'get_myexcerpt', 'advanced', 'get the excerpt' );
}

// Add action
add_action('wpseo_register_extra_replacements', 'pjlm_register_custom_yoast_variables');
