SEO Data Optimization Fails without Any Error Code or Message

Hello Deepak,

I’m sorry you couldn’t complete the SEO data optimization. We have seen unexpected issues where the previously optimized data is invalid or incomplete. We’ll start with a reset of the optimization to ensure we’ve removed any invalid data. We know that resetting the data may sound intimidating, but our How to reset the Yoast indexables guide will walk you through the process step by step. We’ve also summarized 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 the specific reset was successful.
4. Go to SEO > Tools, and under SEO data, click the “Start SEO data optimization” button to allow Yoast to rescan your content.

Please let us know if the reported issue remains after resetting the optimized data.

Please try the suggestions again. As soon as you get the error, while you’re on the SEO Data Optimization screen, please check if there are Javascript errors on your browser’s console? You may follow the steps here – https://yoast.com/help/how-to-find-javascript-errors-with-your-browsers-console/

Thanks for sharing the console errors; it’s helpful. The SEO data optimization feature uses the WordPress REST API to scan posts/pages for the right internal links to show. Your server returned a 500 error when accessing the REST API.

Please contact your web host to review your server setup to determine why the REST API returns the error. There may be a server setting or module that needs to be adjusted such as mod_security. If you are using security plugins they can block access to /wp-json/yoast/ file pathway. You may need to contact them or your host provider and whitelist that URL. Once the server no longer returns the error, we would expect the SEO Data feature to load and work correctly.

In addition, you may also need to adjust cache settings of your site to remove /wp-json/yoast from the caching. If you are not sure how to do that please contact your host provider and/or caching plugin authors.
