Hi - I have the paid version of Yoast SEO, and the feature called links suggestion that is supposed to suggest internal blog posts to which you can link while you are composing a new blog post for better SEO.
This does not work in Cornerstone (that I can see). I submitted a question to Yoast about it and they said:
If you are adding your content through other plugins or theme content boxes, Yoast SEO for WordPress Premium won’t be able to detect it by default or detect it with complete accuracy. In the past, we have tried to parse shortcodes and other content boxes with horrible results so we opted to provide plugin and theme developers with an API that they can use to pass their content to our page analysis. It’s possible that the Yoast SEO plugin isn’t working as expected with your custom page builder. You can read more about it here – https://kb.yoast.com/kb/is-the-plugin-compatible-with-xyz-visual-page-builder/
If you are using a plugin or theme that doesn’t send their content to our page analysis, please reach out to the developer and ask them about adding the functionality to their code. This KB article will help them with the implementation – https://kb.yoast.com/kb/can-i-add-data-to-the-page-analysis/
So I am writing to you in hopes that you are working on this, or at least have plans to. Since Yoast is a widely used plugin, I’m hoping that is the case. It would certainly be a useful feature to have (especially when one is already paying for it). Do you have any information about this?
Thank you!
