Mind sharing some of that evidence? Having worked for a few online ad targeting companies previously with large advertisers and publishers, I gotta say, most of the data we saw coming from marketing campaigns were weak at best. Most of the conversations were around spending campaign budgets fully (which basically meant reducing the quality of targeting to a broad fishing net), and furthermore ROI tended to be measured against some insane advertiser goal not directly linked to conversions (sometimes this was charged via CPC or CPM, which advertisers supposedly obtained from their real conversion metrics). Also, if you're curious (though I can't find any links right now) you should look into the insane things that happen in brand advertising. I recall running a campaign with a very large brand that would pay us for showing users a YouTube video of their product. Their wasn't even a link to the product. They essentially were paying us for "influence".
