A/B testing for Astra
Run cookieless, flicker-free split tests on your Astra pages - free, with no traffic limits and no third-party tracking. Astra works with the block editor and most page builders, so you can test however you build - the class field is always there.
Why it fits Astra
No lock-in
AB Test WP matches variants by a CSS class, so it works inside Astra without replacing your editor or markup.
Fast & flicker-free
The original never flashes - the tested element stays hidden until the assigned variant is applied - and assignment runs in the browser, so Astra pages stay fast and cache-friendly.
Private by default
No cookies and no third-party calls in the page your visitors load. Their data stays in your own WordPress database.
Setup
Adding a test class in Astra
Each variant gets a class from the plugin. Add it to the matching element in Astra - that's the only builder-specific step.
Create the test
In the AB Test WP dashboard, create a test. It generates a class for each variant, for example:
.abtest-hero-cta-v1Add the class in Astra
Select the block or element → Advanced → Additional CSS class(es) (or your builder's CSS class field). Use the class that matches the version you are editing: the one ending in -default on the original, the one ending in -v1 on the new version.
Pick a goal & launch
Choose a conversion goal - a page visit, an element click, a link click, a form submission or a WooCommerce add-to-cart - then start the test and watch results come in.
Verified against Astra with the WordPress block editor in September 2026. Builders change their panels between major versions, so this page names the version it was checked against. Source: WordPress documentation: the WordPress editor.
What you can test on an Astra site
Anything you can give a CSS class: headlines, calls to action, hero images, pricing tables, section order, or whole landing pages via a URL/redirect test. Free covers two-variant tests with up to three running at once; Pro adds up to six variants, advanced goals, WooCommerce revenue, and statistical significance.
Using a different tool as well? AB Test WP works the same way in every major builder - one plugin across every site you build.
How it works
One Astra page, two variants
No second page to maintain, no redirect, and the same cached HTML for every visitor. Here is the whole mechanism.
Both versions ship in one page
You build both versions in Astra and give each one the class the plugin generated: the original gets the class ending in -default, the new version the one ending in -v1. Both sit in the same page.
abtest-hero-cta-default abtest-hero-cta-v1
The browser picks a side
A visitor arrives on the cached page. Both versions start hidden, then the plugin's script assigns the visitor a variant in the browser and reveals only that one, so the original never flashes and no cookie is set.

The count lands in your database
Impressions and conversions are written to your own WordPress tables. Nothing leaves the site, and the CDN keeps serving the same cached HTML to everyone.

FAQ
Astra questions
The things people ask before their first Astra test.
Where is the CSS class field in Astra?
Select the block or element -> Advanced -> Additional CSS class(es) (or your builder's CSS class field). Use the class that matches the version you are editing: the one ending in -default on the original, the one ending in -v1 on the new version.
Can I test a whole Astra page or template?
Yes. Build the second version as its own page and run a URL split test: the redirect happens in the page head before anything paints, each visitor stays on the version they first saw, and the variant's canonical points at the original by default.
Do I have to use the class field, or does point-and-click work on Astra pages?
Both work. Point-and-click runs on the front end of any page while you are logged in with the admin bar showing, so you can click a headline, button or paragraph that Astra rendered and type the alternative without opening the editor. The class field is there when you would rather build the variant in Astra.
