Every finished test learns something, even a losing one.
While a test runs, AB Split Test breaks its results down by audience, device size and secondary goal. When it completes, our agent finds the lesson in those results: the likely reason the test won or lost, the principle behind it, and the main things to try next, which go into your Test Ideas list. A test that lost is recorded too, so the next suggestion won't try the same change again. Every AI request after that reads these results first.
Why use continuous learning?
Know why it won
Each lesson gives the likely reason for the result and the principle behind it, in plain English.
Stop repeating losers
Lost tests stay on the record, so the AI stops suggesting the same change again.
Always a next test
Lessons file follow-up tests for you: one on the same page, one that takes the result somewhere else.
How it works
Recorded when a test completes
A minute after a test completes, it is recorded as won, lost, inconclusive or adaptive (a bandit test with no declared winner). Change the winner and the record updates.
Finds the lesson in your results
Once a test has at least 100 visitors, our agent finds what happened, the likely reason, the principle behind it and what to try next. Your five most recent lessons each add up to two follow-up tests to Test Ideas. Paid plans.
Read before every suggestion
Magic Bar, ChatCRO, test ideas and AI rewrites read your past results first, ranked with the same page on top. Auto-optimize uses them when it writes each next round.
You can correct what it learns
Add your own takeaway
Know why a test won? Write it in one sentence. Future suggestions use your words.
Leave a test out
Had a broken variation or a Black Friday week? Mark the test so its result never shapes future suggestions.
Already on
Nothing to set up. Tests you finished before updating are added too, newest first.
Where to find it
In WordPress, go to AB Split Test > Optimization Hub > Learnings. Filter by outcome and open any test to read its lesson.

Follow-up tests show up in Test Ideas marked "From a past test", with a link back to the test that suggested them.

Test anything in WordPress.
Blocks, pages, posts, page-builder elements, custom post types, templates, shortcodes, HTML, JavaScript, or CSS.
All of it works without workarounds.
The most conversion options
Page visits, clicks, form submits, purchases, active time, scroll depth, JavaScript events, conversion pixels, block or module triggers, and server-side PHP or AJAX actions. We currently support 11 conversion (goal) types.
Point-and-click testing
Click the element you want to improve, review the AI variations, make your edits, and start the test, all without a developer.
Blocks, Bricks, Beaver Builder,
Elementor, Breakdance and more
Deep integration with your page builder means you can test blocks, elements, sections, templates and layout parts without leaving your workflow.
Autocomplete
Calculates when enough data has been collected, then automatically shows the best variation to all. We do the Bayesian statistics calculations, so you don't have to.
Auto-optimize
A winning magic test builds its own next round. The winner becomes the control and AI writes new variations to beat it.
Privacy (GDPR) friendly
We do not store any user identifying data or utilize remote servers for customer data.
Cookie consent tools are respected, so no data transmitted or saved until accepted.
Unlimited Tests, Variations & Goals
Create as many tests as you like with as many test variations as you want.
Unlimited Page Views
Collect as much data as you need to make an informed decision without worrying about credits or usage limits.
Test inside templates, parts and block layouts
Whether you use Block Templates, Beaver Themer, Elementor Templates, Bricks, Breakdance or another theme builder, you can test headers, footers, sections and layout parts directly.
A.I assistant
Our Conversion Rate Optimization Agent scans your site to understand your business & tone, then creates tests for you.
Cache friendly
We prerender your test variations hidden, then use JavaScript to show the appropriate test variation.
You can use full page caches, object caches, pre-rendered cloudflare caches or whatever you like.
External conversions with fingerprint pixels.
Remote cookies no longer work reliably, so we use fingerprinting instead.
Paste our conversion script on your conversion pages, on any domain. The script connects test visitors to conversions, no matter where they end up.
Multiple conversions - subgoals
See how your tests affect other metrics, and analyze your funnel before you decide.
Order Value Optimization
WooCommerce, SureCart, Easy Digital Downloads, Memberpress and more. Optimize for revenue, not only clicks and views.
Analytics integrations
Tag users when they see a test and when they convert. Then you can view your funnel inside your analytics apps.
Dynamic Traffic Allocation: optimize traffic to the winning variation on the fly. Reduce visits to losing variations whilst maintaining significance.
Test Time Remaining
Estimates based on incoming data how long it will take for your test to reach statistical significance.
Webhooks
Send an HTTP POST whenever a test is created or completed, so your external systems stay in sync.
Link To Variation
Create your test, then generate direct links to each variation. You can also force specific visitors to view a particular variation.
Test Ideas
Plan and prioritize your split tests. Score each idea by Impact, Reach, Confidence and Effort and the highest scores rise to the top.
Continuous learning
Every finished test is recorded. AB Split Test finds why it won or lost and what to try next.
Session recordings
Watch real user sessions to see where visitors hit friction or get confused, which you'd never spot in the data alone.
API/MCP/CLI
Control your A/B tests from AI assistants, CI/CD pipelines, or custom applications, so testing fits into the workflow you already have.
Cross-Domain Split Testing
Register an external domain, generate a lightweight tracking script, and serve the correct test variation to visitors on Shopify, HubSpot, or any external platform. Conversion events sync back to your WordPress dashboard automatically.
Cloudflare Workers Integration
Run full-page split tests at the network edge. Variations are served under your original URL with no redirect, flicker, or URL change, so your ads and SEO are unaffected.
Split Test Server
Run split tests on any platform and still control the data. Full-page, code and point-and-click tests, heatmaps and session replays, all from one snippet. Your own visual website optimizer.
