Hi @copperrefections
Please understand that we provide support for the free version of the Yoast SEO plugin on these forums. So please do make sure you are utilizing the free version when running the SEO data optimization process.
Please try resetting our indexables in the database tables by following the steps below?
1. Install & activate the Yoast Test Helper plugin
2. Go to Tools > Yoast Test
3. Locate the Yoast SEO section and click on the ‘Reset indexables tables & migrations’, ‘Reset Prominent words calculation’, and ‘Reset Internal link counter’ buttons. After each click, the page will reload to confirm that each reset was successful. Note: this won’t actually erase your SEO data, which is also stored in WordPress’ default tables. It’ll just reset our index (custom tables) for that data.
4. Go to SEO > Tools, and under SEO data, click the “Start SEO data optimization” button to allow Yoast to rescan your content.
For your site’s health and safety, we recommend creating regular backups of your site and database. This is especially important before installing, updating or removing plugins. Learn more about the benefits of regular backups.
Please then do check if it completes. Otherwise, please refer to this article for more information if there are any JS errors that appear in your browser’s console – https://yoast.com/help/seo-data-optimization-not-complete-successfully/
We are going ahead and marking this issue as resolved due to inactivity. If you require any further assistance please create a new issue.
