Can anyone explain to me how the wpseo_pre_analysis_post_content should be used?
I'm having a hard time finding documentation and it isn't quite clear what I should do.
Yoast's own blog posts says the following:
This filter is called wpseo_pre_analysis_post_content and takes 1 argument: a string containing the post’s content.
I want to use this filter to include my custom fields into the page analysis
