what are some examples of custom template variables in Yoast SEO

1. %%myname%%: This is a custom variable that can be used to output the sentence "My name is Moses" in the front-end. The code to register this custom variable is:

php
add_action('wpseo_register_extra_replacements', 'register_custom_yoast_variables');

function get_myname() {
    return 'My name is Moses';
}

function register_custom_yoast_variables() {
    wpseo_register_var_replacement('%%myname%%', 'get_myname', 'advanced', 'some help text');
}

2. %%pt_plural%%: This variable can be used to output the plural form of the post type in the SEO title template for post type archive pages.

3. %%POSTLINK%%: This variable can be used in the RSS feed template to link back to the original post.

4. %%BLOGLINK%%: This variable can also be used in the RSS feed template to link back to the blog.

5. %%searchphrase%%: This variable can be used in the SEO title template for the search results page.

6. %%name%%, %%date%%: These variables can be used in the SEO title template for author archive pages and date archive pages respectively.

7. %%term_title%%: This variable can be used in the SEO title template for taxonomy archive pages.

The search results also mention that developers can create their own custom template variables using the `wpseo_register_extra_replacements` filter in WordPress. This allows for a high degree of flexibility and customization in how Yoast SEO generates SEO titles and meta descriptions.
