Ahrefs Web Analytics Explained

Ahrefs Web Analytics is a free, lightweight, privacy-friendly analytics tool from Ahrefs, traffic, top pages and referrers without heavy cookies.

What the data-key means

Your site is identified by a data-key in the script’s data-key attribute, loaded from analytics.ahrefs.com/analytics.js.

Why use it

• Free and privacy-conscious (no consent banner needed in many regions)
• Very lightweight script
• Simple, clear traffic reporting

It’s often run alongside GA4 as a simpler, privacy-first second opinion. Watch for it being installed twice (hard-coded and via GTM), Tag Explorer flags duplicates.

How to check yours is working

Run your site through our free Tag Explorer tool, it shows every tag on the page, nested under its GTM container, with the tracking IDs. To confirm a tag actually fires, use GTM’s Preview mode or your browser’s DevTools Network tab.
