Frequently Asked Questions

Common questions about ImproveAB: A/B Testing

Yes. The plugin is GPL-licensed and free forever, with no pageview or traffic limits. It runs complete A/B and A/B/n tests on its own, as many at once as you like, with every goal type and page targeting. Nothing in it is locked.

ImproveAB Pro, coming soon, is a complete version of this plugin that adds statistical significance, probability to beat and the likely range of the uplift, automation and alerts, audience targeting, uneven traffic splits, custom CSS, AI Copy and Style with your own key, webhooks and role controls. You install it in this plugin's place, and it keeps every test, result and setting. The free plugin stays complete without it. See Pro and get an email when it launches.

Yes. Element tests use a CSS class, and every major builder has a field for one: Elementor, Bricks, Divi, the block editor (Gutenberg), Beaver Builder, Oxygen, Breakdance, WPBakery, Avada, Etch, and block themes such as GeneratePress, Astra and Kadence. Build both versions of the element and paste the class the plugin gives you onto each; the plugin shows where that field is in each builder, with a Copy button. Point-and-click tests and URL tests need no class at all.

No. While logged in as an administrator, open any page of your site, click "A/B Tests" in the admin toolbar and choose "Start a test on this page". Click the element you want to improve, write the new version, choose a goal and start the test. Your page, theme and builder are never modified.

It's built to be lightweight. Visitors load one small script (about 18 KB compressed), deferred on WordPress 6.3 and later, plus a few lines in the page head that keep the wrong version from flashing; nothing is fetched from third-party servers, no cookies are set, and pages stay fully cacheable. Results are read from your own database only in wp-admin.

No. The plugin hides untested variants until the assigned one is ready, so the page reveals flicker-free.

Yes. Variant assignment happens in the visitor's browser, so the same cached HTML can be served to everyone, with no cache exclusions needed. When a test starts or stops, the plugin clears the page cache of WP Rocket, W3 Total Cache, WP Super Cache, LiteSpeed Cache, WP Fastest Cache, Cache Enabler, Hummingbird, Breeze, Autoptimize, SiteGround Optimizer, Nginx Helper, WP Engine, Kinsta, Pantheon and the Cloudflare plugin. With any other cache or CDN, clear it yourself right after starting or stopping a test. Script optimizers are covered in the built-in Guide, under "Caching plugins and optimisers".

It sets no cookies, loads nothing from third parties, and sends nothing to us or to anyone else. A random identifier saved in the visitor's own browser keeps their assigned version, and your own database records which version that identifier saw and whether it converted, with the device type and the time. No names, emails or IP addresses are stored with your results. Whether you need visitors' consent for this depends on the laws that apply to your site, so review it with your own privacy policy or counsel. If you ask for consent first, a consent tool can hold the plugin's script back (developers can use the improveab_enabled filter); visitors without consent see the original version and are not counted.

No. Element tests change content client-side and don't create duplicate URLs. For URL/redirect tests, each variant page is given a canonical tag pointing to the original (works alongside Yoast and Rank Math), so search engines understand they're variants of one page.

You can test any element or page, including WooCommerce product and shop pages. A purchase can be the conversion goal, with revenue and revenue per visitor shown per variant. It counts paid WooCommerce orders. An order waiting for payment counts when it is paid; refunds and cancellations are taken off its revenue. So a stopped test's purchase figures can still move a little: an order placed while it ran counts once it is paid, a deleted refund goes back on, and a cancelled order (cash on delivery that never arrived, say) gives its revenue back until it is paid after all.
