Why it exists
Most testing tools do one of three things you don't want.
Lock you into a single page builder, cap your free visitors, or route your visitors through someone else's servers. AB Test WP does none of that.
Cookieless by design
No cookies, no IP address, no user agent, no account data. Assignment lives in the visitor's own browser and the only identifier is a random id.
Works with any builder or theme
Element tests target a simple CSS class, so they work in Elementor, Bricks, Divi, Gutenberg, or a classic theme alike. Or skip the class and point and click.
No traffic limits, ever
It's your server. Results live in your own database, so there are no pageview fees and no account to create.
How it works
Point, click, test, ship the winner.
Open "A/B Tests" in the admin bar, choose "Start a test on this page", then click the element.
A headline, a button, a paragraph. The panel warns if you pick something large or interactive.
Type the second version.
Preview it in place. Elements with inline formatting open as editable HTML so styling survives.
Pick a goal and start.
Page visit, click, form submission or add to cart. When a winner is clear, keep showing it with one click.
Prefer your builder? Paste the generated class into its CSS-class field instead. Same result.
Results
Results you can read.
Impressions, conversions, conversion rate, leader highlighted. Free tells you who is ahead. Pro adds statistical significance, Bayesian probability-to-beat and uplift confidence intervals.
Flicker-free
Survives page caching and CDNs. No cache exclusions required.
Bring your own AI key
Copy ideas use your OpenAI, Anthropic or Gemini key. Nothing is ever sent to us.
Keep showing the winner
One click serves it to 100% of visitors until you've edited the real page.
Uninstall and it's gone
No account, no external dashboard. Results stay unless you choose clean-delete.

WooCommerce guideWhat is AB Test WP?
A free WordPress plugin for A/B testing headlines, buttons, sections and whole pages on your own site. It sets no cookies, has no traffic limits, and works with every page builder and theme. Pro adds statistics, targeting and automation.
Does it slow down my site or cause flicker?
No. Variants are assigned in the browser and rendered without flicker, and the plugin is compatible with page caching and CDNs. Caches are purged when a test starts or stops.
Do I need Elementor, Divi or another builder?
No. Element tests work through a simple CSS class that every builder and classic theme can set, or you skip the class entirely and point and click on the live page.
Is it GDPR-friendly?
The plugin stores no IP address, user agent, referrer or account data. The only identifier is a random id in the visitor's browser. Whether that needs consent is a call for the site owner; the privacy page lists exactly what is stored.
What does Free include, and what is Pro for?
Free creates, runs and measures tests with two variants and up to three running at once, with no traffic limits. Pro adds significance and probability-to-beat, up to six variants, revenue goals, targeting, scheduling, automatic winners and alerts.
