AB Split Test - the self-hosted split testing plugin for WordPress freelancers & agencies.
Prove your work makes the phone ring
You drove the traffic. You rebuilt the pages. Then the client asks what they’re actually paying for - and “trust me, it converts better” is not an answer that renews a retainer.
AB Split Test runs real A/B tests inside the WordPress sites you build, then ties every winner to leads, bookings and revenue. Setup takes minutes, the data never leaves the site, and the report ends the awkward conversation.
Proof, not opinions
Winners tied to leads & revenue
Minutes, not days
Point-and-click, no code
Unlimited everything

Proof, not promises…
Every client’s wins, on one screen
The Agency Hub rolls up tests, winners and heatmaps across every site you manage - so the value of your work is a screenshot, not a debate.
The Agency Hub: every client’s tests, winners and heatmaps in one dashboard - included with the Teams plan.
“A great plugin that’s helped us align our messaging and convert more leads.” TEO, stealthagents.com
“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.”
The real problem…
Clients don’t cancel agencies. They cancel mysteries.
You know the new landing page outperforms the old one. You know the traffic you send is worth money. But until you can show the number, your work is a line item waiting to be cut.
Every change is a coin flip
New headline, new layout, new CTA? Without a test it’s your opinion against the client’s - and the client’s nephew has opinions too.
Unproven work doesn’t renew
When leads dip for a week, the retainer question follows. No numbers means it’s your word against the invoice.
Enterprise tools priced you out
Google Optimize is dead. VWO and Optimizely meter every visitor and move client data to their cloud. Hosted CRO was never built for a roofer’s lead-gen site.
Step one - look…
See where the leads leak
Before you change a single word, watch what real visitors actually do on the pages you built.
Heatmaps
Heatmaps show where attention goes - and where it dies. Filter by test, device, traffic source and anything else.
Session replays
Watch real visits: the hesitation, the confusion, the bounces. Friction you didn’t know existed, on video.
CROassist AI analysis
Our AI agent reads the site, the heatmap data and the competitors, then hands you a ranked list of what’s costing you leads.
Step two - fix…
Point, click, test - right where you built it
No code. No external dashboard. No new workflow to learn. If you can build the page, you can test it.
Magic point-and-click editor
Click any element on the live site - headline, button, form - and launch a test in seconds. The AI can even draft the variation for you.
Inside your builder
Test from inside Blocks, Elementor, Beaver Builder, Bricks, Oxygen, Breakdance or WPBakery - plus shortcodes, CSS selectors and custom themes.
Full-page tests
New landing page vs. old. Whole funnel redesigns. Radical changes, zero risk - real traffic picks the winner.
We call the winner
No spreadsheets, no stats degree. We tell you when a variation has won, and by how much - then autocomplete can serve it automatically.
Tied to money
Track quote requests, bookings and revenue with WooCommerce, Easy Digital Downloads and form goals - and forward it all to GA4, Meta Pixel, Matomo, Plausible, Mixpanel or Clarity.
AI drafts, traffic decides
CROassist audits the funnel and writes the test ideas. Real visitors vote with their wallets. Winners become the new baseline.

Fair questions…
What agencies ask before they install
“Will it slow my sites down?”
No. It’s built to be fast and lightweight, runs inside WordPress, and integrates with 10+ caching plugins. No third-party scripts holding up your pages.
“Will it fight my builder?”
It works inside the builder you already use - Gutenberg, Elementor, Beaver Builder, Bricks, Oxygen, Breakdance, WPBakery - and anything else WordPress renders.
“Is the free thing actually free?”
We email you the plugin and you’re testing in minutes. Lite is free forever - one active test, full analysis - with a 7-day Pro trial on top. No credit card, no time limits.
“What does it cost as we grow?”
Unlimited tests, visitors, goals and variations. Your bill doesn’t go up when your traffic does. Monthly, yearly, or pay-once lifetime - shipping since 2018, 20+ releases a year.
“The free version is better than most paid split testing plugins out there. Plus the included demo with AI analysis discovered some real problems. Thanks for that!” Kyle, Optics Marketing
★★★★★
“If you’ve been putting off A/B testing because it seemed too technical, too expensive, or too time-consuming - stop. This plugin makes it simple, fast, and surprisingly fun.”
Lawrence, WPBakery
