WordPress plugin that adds the content of all ACF fields to the Yoast SEO score analysis.

== Description ==

This plugin ensures that Yoast SEO analyzes all ACF content including Flexible Content and Repeaters.

[Yoast SEO for WordPress](https://yoast.com/wordpress/plugins/) content and SEO analysis does not take in to account the content of a post's [Advanced Custom Fields](http://www.advancedcustomfields.com/). This plugin uses the plugin system of Yoast SEO for WordPress 3.1+ to hook into the analyser in order to add ACF content to the SEO analysis.

This had previously been done by the [WordPress SEO ACF Content Analysis](https://wordpress.org/plugins/wp-seo-acf-content-analysis/) plugin but that no longer works with Yoast 3.0. Kudos to [ryuheixys](https://profiles.wordpress.org/ryuheixys/), the author of that plugin, for the original idea.

This Plugin is compatible with the free ACF 4 Version as well as with the PRO Version 5. Please be aware that it ignores Pro Add-Ons for Version 4. In that case please upgrade to ACF PRO Version 5.

> If you have issues, please [submit them on GitHub](https://github.com/Yoast/yoast-acf-analysis/issues)

Previously called Yoast ACF Analysis.

`add_filter( 'Yoast\WP\ACF\blacklist_name', function ( $blacklist_name ) {
    $blacklist_name->add( 'my-field-name' );

});`

    return $blacklist_type;
});`

= Define custom field a specific heading value =
`add_filter( 'Yoast\WP\ACF\headlines', function ( $headlines ) {
    // value from 1-6, 1=h1, 6=h6
    $headlines['field_591eb45f2be86'] = 3;
    return $headlines;
});`

= Change refresh rate =
`add_filter( 'Yoast\WP\ACF\refresh_rate', function () {

});`
