I want to test the cover of an ebook on my landing page to see which gets more conversions. However, how do you avoid giving the user a bad experience if all your promo materials show one cover, and when they click through to the landing page, they get the B version of the cover? Then it won't look the same as it did in the promo material they clicked on. For example, if I send out an email that shows one cover and the landing page is being A/B tested between two covers, half of the people that click through the email are going to get a different cover on the landing page than they got in the email. Same if they click on a social post that advertises one cover in the image or if I promote the ebook on my website with a thumbnail image that is one of the covers. How do other people manage this when A/B testing visual elements like this? Thanks!
