ACF Content Analysis for Yoast SEO


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

Yoast SEO for WordPress content and SEO analysis does not take in to account the content of a post’s Advanced Custom Fields. 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 plugin but that no longer works with Yoast 3.0. Kudos to 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.

Previously called Yoast ACF Analysis.



After long hours of research, I have come to understand that ACF Content Analysis for Yoast SEO is the source of my problem. Indeed I am creator of wordpress themes and on a site site for photographers, the site always fell as soon as the client uploaded images in batch of 30 or 80 and even by filling only a title or just meta description of the plugin YOAST.
After uninstalling ACF Content Analysis for SEO Yoast all came back in order so this plugin is not stable at all especially when a client must often uploaded images by ACF image or ACF gallery.
Hoping for future updates
Have a good day

Great plugin, but an issue you need to be aware of

This plugin works really well but please be aware of this issue before installing on a live website:

Basically if you are using ACF image fields you can end up with a very high load on your web server when editing posts. On low-budget hosting platforms this could take your website offline.

As far as I know the team are aware of the issue and are working on a fix. Support is good and otherwise, the plugin is great.

Works right out of the box

Just works – straight out of the box. Install & Activate – if you just want basic functionality, then that’s all you need to do. Perfect for handing your site off to clients if you use ACF / Yoast – without them saying ‘but I’ve written loads, why does it say I don’t have 300 words on the page … ‘! Perfect. Thanks all.
