What changes

Sticky mobile CTAs are often reported to lift primary CTA clicks by roughly 10–22% relative on long-scroll pages.

When this tends to work

  • Conditions similar to: Mobile landing pages, lead gen and app install, 2023–2025
  • You can measure Primary CTA click-through rate reliably
  • The intervention is implemented consistently, not half-measured

When to be careful

  • Your audience or product differs materially from the cited context
  • Compliance costs or second-order effects outweigh the lift
  • Evidence label is ab_test—treat wide ranges as planning bands, not promises

Practical takeaway

Use the cited range for prioritization and test design. Verify against your own data before scaling.
