Scrolling CTA in Homepage Hero
For whatever reason, the v.1 of our homepage had the main 'Try' CTA scroll with each hero display. Light research shows that you want your main CTA always present, and not moving. People often make it a part of a sticky nav.
We thought we'd test this, and as it turns out.... drum roll..... a sticky CTA did have slightly higher conversions, but it wasn't that statisticaly significant in our case. We updated our site anyways to have the sticky CTA, but this test goes to showt that your gut and what works for others isn't always what's best.
The best thing to do is test everything and let the data lead the way. What works for others, will not always be what's best for you.
P.S. I love the phrase you used: "let data lead the way."
