Content Page: Sticky Call To Action on Content Page
Hypothesis
If we make the primary call-to-action sticky and always visible while scrolling, then conversion rates will improve because the CTA remains accessible at the exact moment users decide to act
Test Results
Key Learning
Context: Key actions on the content page disappear as users scroll, creating a gap between intent and the ability to act.
What was tested: Sticky CTAs capture conversions from users who reach purchase intent mid-scroll rather than requiring them to scroll back up; the lift depends heavily on page length and scroll depth
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 content page: sticky call to action on content page but produced no statistically significant change. The test was run on a content 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 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
In this simple experiment on an article page, the variation slid out a sticky call to action linking to the next article. The sliding interaction triggered after some scrolling threshold (around 1000px or so). Afterwards, the sticky call to action maintained its floating position. The experiment measured clicks on this "next article" button.
