    That last word, judgment, needs some adjectives.  :-)

    Terrific post, as usual, Sid.  We’ve made the same case, though we’re quite proud of our algorithmic approach to a better answer.  Also worth pointing out that all of this ignores offline marketing impacts which can be driving much of the initial interest.  Directional guidance is exactly right, but don’t yank the rudder!

    It’s a great topic to discuss but hard to talk about attribution in general… It depends on the industry..the type of business, the price level or even whether it’s an ecommerce website or not. I think the most important to understand each channel’s role in your business.

     Hi George,
    Yes the online-offline impact is what a lot of marketers want to measure and that requires econometric analysis – that is another topic/debate altogether !
