At Daisycon Advertisers can choose to make there campaigns more attractive by adding an assist conversion. When they do they give a ‘smaller’ commission to the publisher that had a contribution in the sale or lead. When you look into the statistics and see that you have got a lower commission then you had expected, it could be that you didn’t had the last click but had an assist conversion in the sale or lead. The good news is that you can even get a commission when there is not a direct sale.
