The <a href="https://wordpress.org/plugins/semrush-seo-writing-assistant/" rel="ugc">SEMrush SEO Writing Assistant</a> plugin read only from post <code>title</code> and post <code>content</code> elements for the real time check.
This lightweight plugin allows you to use an arbitrary value for that check in addition to those values.
So, if you are using some kind of a page builders, field managers and so on, you have only to define a constant in your wp_config.php file and eventually to write a little bit of JavaScript code in order to specify which fields.
Note that the plugin don’t replace SEMrush SEO Writing Assistant but is intended to be used together.
<h3>Usage</h3>
Once the plugin is activated you can configure it by defining following constants in your wp-config.php:
<ul>
<li><code>SWA_SEMRUSH_CUSTOM_FIELDS_PLUGIN_AUTOENABLE</code></li>
</ul>
Automatically enable use of additional text value for SEMrush check. The default value is <code>false</code>. 
This is the only configuration you have to do in order to have the plugin feature working. 
For example:
<pre><code>define( 'SWA_SEMRUSH_CUSTOM_FIELDS_PLUGIN_AUTOENABLE', true );
</code></pre>
<ul>
<li><code>SWA_SEMRUSH_CUSTOM_FIELDS_PLUGIN_INTERVAL</code></li>
</ul>
Allows to change the interval between automatic updates of the text used by SEMrush checks. 
The default value is <code>5</code> seconds.For example:
<pre><code>define( 'SWA_SEMRUSH_CUSTOM_FIELDS_PLUGIN_INTERVAL', 10 );
</code></pre>
You can alernatavely control the plugins programmatically, by using 
 semrush_seo_writing_assistant_post_types (optional) filter and <code>SeoWritingAssistantSEMrushCustomFields</code> JavaScript object (see below).
<h3>API</h3>
<h4>WordPress Hooks</h4>
**<code>swa_semrush_custom_fields_settings</code> **
Filters plugin settings values.
<pre><code>apply_filters( 'swa_semrush_custom_fields_settings', array $settings )
</code></pre>
<code>semrush_seo_writing_assistant_post_types</code>
Filters post types where to enable plugin. Default to <code>array( 'post', 'page', 'product' )</code>.
<pre><code>apply_filters( 'semrush_seo_writing_assistant_post_types', array $post_types )
</code></pre>
The filter has the same name as the one used by SEMrush SEO Writing Assistant plugin (since version 1.0.4) used for the same purpose.
<h4>JavaScript Event</h4>
<code>seo-writing-assistant-semrush</code>
This event allows you to update the text for SEMrush analysis. 
The following example will update text for SEMrush check every 5 seconds, using <code>excerpt</code> and <code>my_custom_fields</code> custom field values (working both with block and classic editors):
<pre><code>jQuery( document ).ready( function() {
 var swa = new SeoWritingAssistantSEMrushCustomFields( { interval: 5 } );
 jQuery( document ).on( 'seo-writing-assistant-semrush', function( event, data ) {
 data.html += jQuery( '#excerpt' ).val() + "\n"
 + jQuery( '.editor-post-excerpt__textarea textarea').val() + "\n"
 + jQuery( '#my_custom_fields' ).val();
 } )
} );
</code></pre>
Note that if you have previously defined constant <code>SWA_SEMRUSH_CUSTOM_FIELDS_PLUGIN_AUTOENABLE</code> to <code>true</code>, 
you don’t have to create new <code>SeoWritingAssistantSEMrushCustomFields</code> object.
<h4>JavaScript API</h4>
<code>setHtml()</code>
The following example will update programmatically the text used by SEMrush check with an arbitrary value:
<pre><code>jQuery( document ).ready( function() {
 var swa = new SeoWritingAssistantSEMrushCustomFields( { interval: 0 } );
 swa.setHtml( 'foo baz bar' );
} );
</code></pre>
<h4>Advanced Custom Fields</h4>
The plugin checks if Advanced Custom Fields is active in your WordPress instance and adds a custom setting to each field 
(only for <code>input</code> within text, radio and checkbox type, <code>textarea</code> and <code>select</code> elements) allowing you to add his value 
to SEMrush check without having to write any additional JavaScript code.
<h4>Autodiscovery</h4>
The plugin also automatically add to text used by SEMrush checks, the values of all HTML elements 
with <code>swa-scf</code> class or <code>data-swa-scf</code> attribute. 
This will applied only for <code>input</code> (within text, radio and checkbox type), <code>textarea</code>, and <code>select</code> elements.

Ahrefs SEO WordPress Plugin is being deprecated
We’re retiring the Ahrefs SEO WordPress plugin on October 31, 2025. 
Before that date, please export any content audits you want to keep, as the plugin will no longer be available afterward. 
You can continue checking your traffic, ranking keywords, backlinks, and running Site Audits — all inside Ahrefs Webmaster Tools, completely free for domains you own. 
<a href="https://ahrefs.com/webmaster-tools" rel="nofollow ugc">Learn more at ahrefs.com/webmaster-tools</a> 
We’re also bringing the same functionality as this plugin directly into the Ahrefs Toolkit, so stay tuned for announcements.

Automate content audits and grow organic traffic to your WordPress website with Ahrefs SEO plugin.
The Ahrefs WP plugin shows you how each article on your blog performs for a chosen target keyword based on Ahrefs, GA and GSC data. Then, it suggests what you can do to improve their performance.
Content audits
Most of us are so focused on publishing new content that we neglect the content we already have.
This is a mistake because not everything you publish will be a home run. Sometimes, it’ll fail to rank on Google, or convert, or contribute to your business goals in any meaningful way.
When this happens, you shouldn’t just leave the page to die a slow, painful death. You should revisit it, figure out what went wrong, and take action to improve its performance.
The Ahrefs WP plugin automates the entire content audit process and kicks back recommendations.

Unique to Ahrefs SEO plugin
There are a lot of other SEO plugins in the market. So you must be thinking, why another one? Since the Ahrefs WordPress plugin focuses on content audits, it complements other SEO plugins rather than replaces them.
<ul>
<li>
Content audit 
The plugin regularly conducts content audits of your website and gives actionable suggestions on improving article performance for a target keyword based on Ahrefs, GA and GSC data.
</li>
<li>
Performance score 
The plugin puts audited pages in 1 of 3 buckets based on their performance (well-performing, under-performing, non-performing). Besides evaluating individual pages, it also calculates the performance score that reflects the overall performance of the website’s content
</li>
<li>
Integration with GA and GSC 
We don’t just pull data into your WordPress Admin and show you the same information that you can see on your GA and GSC dashboards. Your GSC and GA connection helps us to provide you with better target keyword recommendations and ideas of what to do next, so you can take actionable steps towards getting more search traffic. All GA and GSC data is stored in your website’s database and is never sent to Ahrefs.
</li>
<li>
Integration with other SEO plugins 
If you have preconfigured target keywords in Yoast, RankMath or AIOSEO, you don’t need to enter them in our plugin. Ahrefs SEO will pull and update them automatically with every content audit.
</li>
</ul>
And the usual best-practices
Other than the unique features, we make sure that we adhere to the best-practices for WordPress plugin development.
<ul>
<li>
Lightning fast 
The plugin puts a minimal load on your WordPress servers.
</li>
<li>
Easy to setup and configure 
The setup wizard is a three step configuration that gets you started in less than 5 minutes.
</li>
