The best Split Testing & Conversion Optimization plugin for WordPress.

Improving your WordPress site doesn't have to suck

There are plenty of tools that promise to help you optimize your website. Most platforms are overwhelming, overpriced, or crappy.

Not us, we're refreshingly simple-yet-powerful. An all‑in‑one optimization and split testing system with an eight‑year track record to back it up.

I love AB Split Test. Simple interface. It does exactly what it says. Reporting is clear and the support is unbelievably excellent. I highly recommend this plug-in.

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.
