Homepage: Cart Resume for Returning Drop-Off Users
Hypothesis
Showing returning visitors who abandoned checkout a summary of their progress and a 'resume' option will increase completed purchases.
Test Results
Key Learning
Problem: Visual elements on the homepage aren't doing enough to communicate value, build trust, or guide users toward the next step.
What worked: Re-engagement of near-converters (users who started but didn't finish) through personalized re-entry experiences is a high-ROI tactic. Reducing re-start friction is especially important for multi-step purchase flows where momentum matters. (+10.0% lift)
Takeaway: A meaningful improvement that compounds with other optimizations. Use this win as a foundation for further iteration on adjacent elements.
How to Apply This to Your Site
This experiment demonstrated that homepage: cart resume for returning drop-off users can produce a +10.0% improvement in conversions. The test was run on a homepage page in the e-commerce industry.
Before you test: Consider that personalization tests typically require adequate traffic to reach statistical significance. Run your test for at least 2 full business cycles to account for weekly traffic patterns.
What Was Tested
Test #510 on Formelskin.de: non-purchasers returning to homepage were shown a 'Welcome Back' summary with completed steps (vs control where they restarted the flow). +9.7% sales. Test #521 : users who completed checkout step 1 and returned after 7+ minutes were shown a filled shopping cart icon with resume functionality. +6.1% sales.
