I came across a recent Forrester post on Attribution and felt the need to comment… I’ll be short and to the point!
I agree the concept of attribution is not new but unfortunately there are still many issues that need to be addressed, such as…
1. Ad servers reliance on their tag to be served on the last visit preceding an action. Unless I’m mistaken, ad servers above can only attribute credit for prior engagements if the last click preceding the conversion is goes through their server. Unfortunately most conversions are preceded by visits from direct navigation and/or natural search. So unless the ad server integrates with site analytics data, they can’t attribute credit for a majority of online conversions.
2. Lack of an agreed upon methodology for recasting the cost per action across the touch-points that played a supporting role. How far back do you go? How many impressions are worth one click? How do you split the credit across different types of media? We have our views and am sure others have theirs. And most are probably based on sound logic.
3. Acknowledgment that our ability to measure impact is severely limited by increasing use of multiple devices (work, home, mobile) and cookie deletion. We’ve seen for years that users often browse at work and buy at home. Now they are relying more and more on their mobile devices for browsing, making it pretty tough to figure out how and where they are becoming engaged and interested in our offer. For every action we can measure via cookies, there must be 3-4 that we can’t measure.
To sum it up, engagement mapping and attributing credit across touch-points is an important and useful approach. But it alone will not tell the whole story. Market testing and surveys should also be included in your toolkit for determining what works in online media.
