Add Custom Fields’ Content to Rank Math SEO Analysis

Before we start, I would like to remind you that MB Rank Math supports just the Text, Textarea, and Wysiwyg fields from Meta Box. Besides, it also supports cloneable fields (or repeated fields).

Method 1: Configure Custom Fields Using Meta Box Builder

If you use Meta Box Builder - a premium extension of Meta Box - to create custom fields, the configuration is extremely quick and simple.

Visit Meta Box > Custom Fields and go to the field group you want.

Go to Custom Fields submenu to find the field you want Rank Math to analyze its content for SEO

Now, open the field that you want Rank Math to analyze its SEO content. Then, move to the Advanced tab and add new Custom settings like this:

Add Custom Settings to custom fields

Type rank_math_analysis and true as I did.

Finally, click Update or Save.

Method 2: Configure in the setting file of the field

In case that you don’t use Meta Box Builder and just create fields manually with code, add this to the settings of the field you want:

'rank_math_analysis' => true

See the Results in Rank Math SEO Analysis

After following all the instructions, you can see the content of the field displayed in the Rank Math SEO Analysis. For example, Rank Math analyzes my content in the description field and displays the information about length, focus keyword, …

Rank Math analyzes my content in the description field

The rest of your work now is writing SEO-optimized content.

Final Words

By default, the custom fields’ value is often not added to the content analysis section of an SEO plugin. Meanwhile, this kind of content is also evaluated and ranked by Google. Therefore, it’s important for webmasters, SEOers, and writers to make these content SEO-optimized.

With MB Rank Math integration, users of both plugins will now save a lot of time and effort to optimize website content for SEO. If you use Yoast SEO, Meta Box already has a similar integration named Meta Box for Yoast SEO. It also helps you to add custom field content to Yoast SEO analysis.
