“If we even improve conversion on our page by 1% or 2%, it would pay for the Spiralyze contract. Most of the tests we've run have improved conversion rates by 20-50% and they have tests mapped out for the rest of the year. It is not even close to what we could've done on our own and is significantly better.”

Bill Carney
