Hello @lucytech
Thankis for reaching out; I’ve addressed your concerns below:
wpseo_taxonomy_meta
The?wpseo_taxonomy_meta?field contains the SEO title, a meta description, a focus keyphrase, related keyphrases, and synonyms for?taxonomy items, like categories and tags. I understand that you would like to optimize the autoloading of the entry in your database. Deleting this field will remove all of the hard work you’ve done toward the SEO of your taxonomy items.
If you are familiar with editing serialized data, you can manually remove the taxonomy information for any taxonomy that is no longer in use on your site. You may want to use an editor to review and modify serialized data. Moreover, there’s an open issue where when you delete a taxonomy (for example, a category), the information stored in wpseo_taxonomy_meta isn’t removed. We’ve added you to the list to be contacted when we have a resolution.
wpseo_titles
The wpseo_titles record in your wp_options table is where we write some of the plugin’s configuration settings, such as the Search Appearance settings where you can configure post types, archives and more to be indexed or not.
