Build and run A/B tests inside the Webflow Designer

Split is a native A/B testing platform that lets you create experiments directly in the Webflow Designer, track conversions, and view results in a real-time dashboard - no code, no external scripts, no developer required.

1. Create tests in the Designer Extension - Open Split inside the Webflow Designer, select elements on the canvas, and assign them to Variant A or Variant B. No custom code, no copy-pasting scripts.
2. Zero-flicker delivery - split.js is 4.2KB and resolves variants in under 12ms. Your visitors never see a flash of the wrong content.
3. Sticky, deterministic assignment - Each visitor is hashed to the same variant every time they return. Consistent experience across sessions with no server-side state required.

Three test types. One platform.

1. Element A/B tests - Show or hide different elements on the same page. Test headlines, CTAs, images, forms, pricing layouts, and social proof sections.
2. URL redirect tests - Split traffic between entirely different page designs. Perfect for testing a full landing page redesign against your current page.
3. Multivariate testing (MVT) - Test multiple elements at once (e.g. headline + CTA + hero image) without needing the massive traffic a full grid would require. Split uses a smart sampling technique that covers every combination with a fraction of the variants.

Statistics you can actually trust

Most A/B testing tools punish you for peeking. Every time you check results before the test is "done," you make false positives more likely - so you either wait weeks for an answer or act on results that aren't really there. Split solves this.

1. Check results anytime without breaking the math - Split uses a modern statistical method (published in 2021) that stays valid no matter how often you look. Watch your test as it runs, call it early when you're confident, and trust the result.
2. Smarter starting point for faster answers - Split's engine comes pre-tuned with what typical lifts look like for different element types (headlines, CTAs, social proof, layouts, forms, images). That means you reach a clear answer sooner, even on sites with only a few thousand visitors a month.
3. Clear answers, not just a yes/no verdict - See the probability that each variant is best, the likely range of improvement, and a simple 3-tier confidence indicator (collecting / likely signal / confident). Make decisions with full context.

Track the conversions that matter

1. Click goals - Track clicks on any element: CTA buttons, links, form submits, navigation items.
2. Pageview goals - Track visits to specific URLs like thank-you pages, checkout confirmation, or signup completion.
3. Scroll depth goals - Track when visitors scroll past a threshold (25%, 50%, 75%, 100%).
4. Time on page goals - Track engagement duration (10s, 30s, 60s+).
5. Cross-page goals - Set up a test on your homepage and track conversions on /pricing or /signup. The visitor is assigned a variant on the test page and tracked wherever they convert.
6. Multiple goals per test - Add as many conversion goals as needed. Mark one as "primary" to drive the significance calculation and winner banner.

GDPR compliant out of the box

Split works with the consent management platforms Webflow teams actually use:

1. Finsweet Cookie Consent (v1, v2, and Consent Pro)
2. Cookiebot
3. OneTrust
4. Cookie Yes
5. Osano

When a consent manager is detected, Split automatically waits for analytics consent before tracking any events. No tracking fires until the visitor grants consent - fully compliant with GDPR, ePrivacy, and CCPA.

No consent manager on your site? Split tracks immediately, which is appropriate for sites outside GDPR/CCPA jurisdictions.

The Split assignment cookie is minimal and strictly necessary - it only stores which variant the visitor was shown.

Built for teams

1. Three roles - Owner (full control), Admin (billing + team management), and Member (view and edit tests).
2. Team switcher - Users on multiple teams can switch between them from the sidebar.
3. Shared access - All team members see the same sites, tests, and results.
4. Site transfer - Move sites between teams you manage.

How it works

1. Connect your Webflow site - Authorize via OAuth. Split connects securely to your site in one click.
2. Open the Designer Extension - Inside the Webflow Designer, open Split from the extensions panel.
3. Create a test - Pick a test type (A/B, URL split, or multivariate), name it, and set your traffic percentage.
4. Assign variants - Select elements on the canvas and connect them as Variant A or Variant B. Add conversion goals.
5. Publish and wait - Publish your Webflow site. split.js handles variant delivery and event tracking automatically.
6. View results - Open the Split dashboard to see conversion rates, Bayesian probabilities, time-series charts, and audience breakdowns. Check anytime - results are always valid.
