Listing: Sticky Call To Action
Hypothesis
If we implement 'Sticky Call To Action' on listing pages (In this experiment, a floating top navigation was shown with a "Join" button), then key conversion metrics will improve.
Test Results
Key Learning
Context: Key actions on the listing disappear as users scroll, creating a gap between intent and the ability to act.
What was tested: REAL-WORLD TEST: 'Sticky Call To Action' was tested on a live listing page. The test involved 1,057,325 real visitors. Full statistical results require paid access. Test methodology: In this experiment, a floating top navigation was shown with a "Join" button. In the control, the navigation was only visible at the top of the page. ...
Result: No statistically significant difference was detected. CTA changes that don't move the needle often mean the bottleneck is elsewhere — consider testing the surrounding context or the value proposition instead.
How to Apply This to Your Site
This experiment tested listing: sticky call to action but produced no statistically significant change. The test was run on a category page page in the cross-industry industry. Inconclusive results suggest this particular change may not be a priority — focus testing effort on higher-impact areas.
Before you test: Consider that cta tests typically require large sample sizes to detect small effects. Run your test for at least 2 full business cycles to account for weekly traffic patterns.
What Was Tested
In this experiment, a floating top navigation was shown with a "Join" button. In the control, the navigation was only visible at the top of the page. Also keep in mind that signup starts were also triggered throughout multiple CTAs throughout the page and from particular job detail pages. The a/b test ran on a listing page of - a casting call job site. Impact on signups and checkouts was measured.
