Stop leaving conversions to guesswork.
When testing lives in a separate tool, it is easy to stop testing altogether. Then a page converting at 2% stays at 2%.
That’s money left behind on every campaign you run.
Leadpages puts A/B testing inside the same platform where you build and publish your pages.
No separate toolNo developer workflowNo additional testing stack

Why your data is better
Zero flicker. Clean data.
Real statistical rigor.
Most client-side tools rewrite the page after it loads, so visitors can see the original before the variant appears. Leadpages assigns variants on the server, before the page renders.

Before first paint
The variant is chosen on the server, so the page renders correct the first time. No flicker, no layout shift, no original version flashing past.

FAQ
Common questions about A/B testing
No. Create a variant, pick a goal, set your traffic split, and publish. Everything happens inside the editor. No code, no JavaScript snippets, no tag manager configuration.
Google shut it down in September 2023. Leadpages includes A/B testing from the Grow plan ($99/mo), with no traffic cap on any plan.
The statistical engine will tell you when you have enough data to declare a winner with confidence. More traffic means faster results, but there's no minimum to start a test.
A/B testing (Grow $99/mo) splits traffic evenly and measures which variant converts better. Smart Traffic (Optimize $199/mo) uses AI to route each visitor to the variant most likely to convert them. They work together: A/B testing finds winners, Smart Traffic routes intelligently.
Yes. You can run several variants at once — A, B, C, D — and split traffic across all of them. The exact number depends on your plan.
Full Optimization (Scale $399/mo) runs a continuous testing loop: test, declare winner, generate next variant, test again. It's designed to run without manual intervention after initial setup.
