The single pop-under ad that you speak of is not something new, it’s a cross-sell ad that has been in existence on the Titan site for years. Our affiliate links carry a 30-day cookie that will track your affiliate ID on any purchase on our site; there are no traffic leaks on any of our affiliate destinations. Nothing's changed on your end? I'm happy to work with you to see if we can get your numbers back up to where they used to be.
