Feature
Cross-Domain Split Testing
Split test across multiple domains. Send variation A to a page on your WordPress site and variation B to a page on any external platform. Results land in one dashboard.
Test Beyond Your WordPress Site
Until now, every variation in your test had to live on your WordPress site. If you wanted to test a completely different page on Shopify, a landing page built in Lovable or Astro, or any external URL, you were stuck. Cross-domain testing removes that limitation. Your variations can live anywhere.
One Script, Any External Platform
Go to Tracking and Privacy in your AB Split Test settings, add your external domain, and copy the generated script. Paste it into the header of your external site and you are done. AB Split Test handles the rest.
All Your Usual Conversion Goals Still Work
Page visits, element clicks, link clicks, time active, scroll depth, URL conversions, and more all work exactly as normal across external domains. The only exceptions are WordPress-specific integrations like WooCommerce or Easy Digital Downloads, which require WordPress to function.
Optional CDN Integration
If your external platform uses Cloudflare or Bunny CDN, you can connect it inside the settings by adding your hostname and API key. This keeps your test running at full speed with cache clearing handled automatically on variation updates.

A.I assistant

Order Value Optimization
WooCommerce, SureCart, Easy Digital Downloads, Memberpress and more. Dont just optimize clicks and views, but revenue.
Analytics integrations
Tag users when they see a test and when they convert. Then you can view your funnel inside your analytics apps.

Test Time Remaining
Estimates based on incoming data how long it will take for your test to reach statistical significance.
Webhooks

Test Ideas
Plan and prioritize your split tests. Score each idea by Impact, Reach, Confidence and Effort and the highest scores rise to the top.
Session recordings
Watch real user sessions to discover friction points, confusion, and conversion opportunities you'd never find in the data alone.
