Why am I not seeing any leads/sales generated on a campaign when I know leads/sales must have been generated?

There are some reasons why this could happen. These include, but are not limited to surfers visiting a campaign page through another member link, surfers entering invalid data, surfers not fully completing the signup, surfers data not matching campaign demographic requirements, and surfers having cookies disabled on their computer. Generally speaking, most cases of the untracked test or friend-generated leads are explained by a member simply unfamiliar with all the details an advertiser requires to validate a lead as real.
