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. 
Have questions? Our support team is here to help: <a href="mailto:support@ahrefs.com" rel="nofollow ugc">support@ahrefs.com</a>
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>
</ul>
