Yes, you can A/B test on Webflow using third-party tools. Webflow doesn't have built-in A/B testing (Webflow Optimize is limited). Use ExperimentHQ: add one snippet to Project Settings → Custom Code, then use the visual editor to create tests. Setup takes 10-15 minutes.
Who this is for
- Webflow designers who want to optimize conversions
- Agencies managing client Webflow sites
- Startups using Webflow for marketing sites
Who this is NOT for
- Sites with under 1,000 monthly visitors (need more traffic)
- Webflow e-commerce checkout testing (limited support)
What About Webflow Optimize?
Webflow announced "Webflow Optimize" for native A/B testing, but it has limited availability and is still in early access. For most Webflow users, third-party tools like ExperimentHQ remain the best option. We'll update this guide when Webflow Optimize becomes widely available.

Webflow-Specific Tips
Use Webflow's class structure
Webflow's consistent class naming makes it easy for visual editors to target elements reliably across pages.
Test CMS-powered pages
You can test template changes that apply to all CMS items (like blog post layouts or product pages).
Track Webflow form submissions
Set form submission as your conversion goal to track lead generation effectiveness.
Test interactions and animations
Webflow's interactions are powerful, but do they help conversions? Test pages with vs without animations.
Common Mistakes
❌ Forgetting to publish after adding the snippet
Changes to Custom Code only take effect after you publish. Always publish after adding or updating the snippet.
❌ Adding snippet to Footer Code
Adding to Footer Code causes flicker. Always use Head Code for A/B testing snippets.
❌ Not testing mobile breakpoints
Webflow sites are responsive. Preview your variations at all breakpoints before launching.
