Questions
What counts as a conversion?
The action your page exists for: a signup, a demo request, a purchase, a trial. Its value can be the revenue of a sale, or for a signup the yearly revenue of a customer times the share of signups that become customers.
How is the lift calculated?
As a relative change on your conversion rate: a 20% lift takes 3% to 3.6%. The extra conversions are your current conversions times the lift, and the revenue is those conversions times the value of one.
What lift can I expect?
It depends on how much the page changes. Rewording a button tends to move little, while a new promise in the headline or a new order on the page can move a lot more. An A/B test is how you find out.
Is the lift the same for every visitor?
Rarely. Visitors from an ad, from search and from a newsletter read the same page with different questions in mind. That is why Polish picks the best version for each kind of visitor instead of one version for everyone.
