Adds all ACF fields into the content being analyzed by Yoast’s WordPress SEO Plugin
This plugin gets every string out of ACF (Advanced Custom Fields) and puts it into the SEO analysis for Yoast’s WordPress SEO plugin using the <code>wpseo_pre_analysis_post_content</code> filter hook.
This plugin is specifically made for ACF and its field types so you’ll need to be using ACF. This should work with Flexible Content and Repeaters too.
Requirements: 
1. <a href="https://wordpress.org/plugins/wordpress-seo/">Yoast’s WordPress SEO</a> 
1. <a href="https://wordpress.org/plugins/advanced-custom-fields/">Elliot Condon’s Advanced Custom Fields</a>
TL;DR for below note: Ignore keyword count on Yoast’s first tab (General), click onto the second tab (Page Analysis).
NOTE: The plugin may appear to not work on first look. The data is affected, but since the first tab of Yoast’s SEO plugin uses front-end Javascript to count the number of times the word is used in the Content field, it won’t count the true keyword density of your page.
Another note: If you don’t display whatever string that this plugin adds to analysis, it won’t count either.

WordPress SEO ACF Content Analysis

I was going to complain that it was picking up fields that shouldn't be picked up, but that's what the filter is for. Very easy to use. It started working instantly without any configuration.



Works well

There are situations when we create custom fields to store real content for the posts. They are actually displayed in the frontend. Search engines such as Google or Bing see them and analyze them. But by default, Yoast SEO plugin takes only post content to analyze for SEO score and gives us feedback based on the post content. The plugin doesn’t analyze the all the content that appears to the search engine, which is a big missing part and that sometimes confuses us in SEO term.
So, the plugin MB Yoast SEO Integration fixes that problem by allowing us to add custom fields to the content analyzed by Yoast SEO plugin. This way, the Yoast SEO plugin and search engine will see the same content and we will have a correct advice for SEO content as well as correct SEO score.
