So, here's the story... I'm promoting a certain affiliate program right now. The site that I'm sending surfers to, has an email collection box on the index page to get into the rest of the site. So surfers need to enter their details to see the whole site. So if they go to the site, enter their email and don't buy immediately, they go onto the site's email list for weekly emails. These emails include newsletters and discounts. It just came to my attention that if they buy through a link in one of these emails a week (or month) later, the system is made so that I don't get credit. How should I feel about this?
Sites have different cookie lengths. The program I run is 30 days but some sites are just hours. Nothing you can do really.
