dynamic meta tags in Yoast

Yoast SEO includes powerful features to automate the generation of SEO titles and meta descriptions for WordPress and Shopify sites, using dynamic snippet variables. These snippet variables help you create consistent, well-optimized metadata for your homepage, posts, pages, taxonomies, products, and more—improving your site's SEO with minimal manual effort. What Are Snippet Variables? Snippet variables are placeholders that Yoast SEO automatically replaces with relevant site or content data when generating titles and meta descriptions. For example, the variable %%title%% shows the current post’s title, while %%sitename%% inserts your site’s main name, minimizing maintenance and ensuring accuracy and consistency. Yoast SEO Meta Snippet Variables Types of Snippet Variables in Yoast SEO Yoast SEO supports several variable types, making it suitable for basic blogging, advanced custom post types, WooCommerce stores, and more.

Yoast Custom Variables The final three advanced variables let you pull data from non-standard WordPress elements, such as WooCommerce products. But how do you know which field or taxonomy name to use with these variables? Custom Fields To locate a custom field name, follow the steps provided . Once you identify the field name, replace with it. Example 1: If the custom field is named myfield, the variable will be: %%cf_myfield%% Example 2: If the custom field starts with an underscore (e.g., _anotherfield), keep the underscore in the variable: %%cf__anotherfield%% Note: Custom fields that store arrays (lists of related values) cannot be used directly with the %%cf_%% variable. In such cases, you or your developer will need to create custom template variables. Custom Taxonomies You can find the name of a custom taxonomy in the URL of your WordPress backend while editing it. Example URL: edit-tags.php?taxonomymycategory&post_typemyposttype In this example: The custom taxonomy is mycategory The custom post type is myposttype To display all categories assigned to a myposttype page, you would use: %%ct_mycategory%% To output the description of a specific taxonomy (e.g., mycategory) on its archive page, you would use: %%ct_desc_mycategory%% Yoast WooCommerce variables The variables listed below are examples you can use with WooCommerce.
