Landing Page: Mobile Plan Page Zip Modal Relevance
Test Results
Key Learning
Problem: Mobile users experience the landing page differently — smaller screens, touch targets, and limited attention require purpose-built design.
What worked: The variant addressed this conversion friction directly. (+9.3% lift)
Takeaway: A meaningful improvement that compounds with other optimizations. Copy is the cheapest element to iterate on — test different headline frameworks and value propositions to push this further.
How to Apply This to Your Site
This experiment demonstrated that landing page: mobile plan page zip modal relevance can produce a +9.3% improvement in conversions. The test was run on a landing page page in the energy & utilities industry. With 19,034 visitors in the sample, this is a robust result.
Before you test: Consider that copy & messaging tests typically require large sample sizes to detect small effects. This test ran for 30 days — plan for at least that long.
This result reached 95% statistical confidence, meaning there is a very low probability the observed effect was due to chance. Results at this confidence level are generally considered reliable for making business decisions.

Does a 90-Day Plan-Change Guarantee Badge Increase Click-Throughs?
Ambiguity > absence. A vague benefit callout can create more friction than no callout at all: visitor diagnostics showed users were drawn in by the badge (time-on-page up, bounce rate down) but exit rate rose and FAQ-section attractiveness spiked — a signature of users searching for answers and not finding them. The same concept won at a sister brand whose variant used descriptive benefit-framed copy ("we'll help you find the right plan if this isn't a fit"); the variant in this test used short labelled-badge copy that raised more questions than it answered. The lesson is not that benefit guarantees fail — it's that surfacing one with insufficient context can backfire by introducing uncertainty the page doesn't resolve.
