Last–Click Attribution refers to a web analytics model in which the “last click” is given credit for a sale or conversion. In other words, if someone comes to your website and orders, you should have a web analytics system in place that tells you where that customer came from. DCMnetwork will only be attributed with the sale if the user had come from a DCMnetwork affiliate site and converts within cookie period.
Most advertisers think that they are paying twice for transactions because they attribute them to 2 tools. Using Google Analytics resolves this issue. It will attribute the conversion to the last click that led to the sale.
