Split Testing & Conversion Optimization plugin for WordPress
Find the content that sells best.
Everyone has opinions, you discover proof.
The features that the team has built into this tool are fantastic. I've paid thousands more annually on different solutions that were much more complex to set up to do the same things that AB Split Test does.
If you do landing pages, lead conversion pages, anything related to ecommerce too, this is a must to scale and know what can effectively work or not and save not only money but time. If you're a beginner: buy it. If you're a pro: buy it.
