Yoast SEO doesn’t count words and SEO for Layout Builder Pages
Unfortunately Yoast plugin cannot read the data from our builder as it is not added into the “Text Editor” are which they only scan, but this does not mean it does not appear on page or that it will not be scanned by search engines.
Data from the drag and drop layout builder is not written inside the text editor into shortcodes like most layout builders on the market in order not to write tons of data of irrelevant content to your database and make it move super slowly.
If you feel that you have some relevant content which you might want to test using this specific feature of this plugin, you can easily do that by adding the text you want into the Text editor directly. This can be done by clicking the “Toggle Layout Builder” button again to switch back to text editor mode, insert the content you want into the Text editor area and then switch the page content back to Layout Build Mode when you want to go back.
Note: You must use the Publish/Update button if you add content in the text editor area, the “Save Layout Settings” button will only save the layout builder settings.
