I think there's a bit of a gap in which assumptions are employed. It's not clear how much the average consumer knows about targeted ads, and without knowing that, we can't assume anything about what they want. Furthermore, if we ask questions that assume unknowns, the results are useless -- asking for approval of targeted ads means two different things if the respondent does or does not understand that the ad network has to profile them to accomplish this.
First of all, it's important to acknowledge that these ad networks are already accumulating a whole lot of information for a variety of purposes: click-through rates, ad placement effectiveness, ROI, etc. They just don't directly tell consumers about this. In fact, many networks have been tracking individuals from ad impression all the way through purchase (conversion tracking) as yet another metric of successful advertising -- and for those of you who buy ads, you understand how powerful this knowledge is. These already existing uses of data are incredibly helpful for advertisers (and the networks too, for ad placement), but it's not clear if consumers realize this is happening.
Online behavioral advertising is probably just a new use for already collected data. The data's already warehoused, and it would take an awful lot of arm-twisting to reduce what ad networks collect -- because it's used for more than just OBA.
So I think the set of questions we ask consumers should be changed from "do you want targeted ads?" to the more precise pair of queries: "is it acceptable for ad networks to build a profile on you?" and "may ad networks use this profile to customize ads you see?" We don't yet understand if people want this data collected, moreover want it used for OBA. This distinction is necessary, because I think there are three groups of people here:
- people who don't want a profile built or their browsing habits recorded at all.
- people who accept conversion tracking but want to see the same ads as everyone else.
- people who accept tracking and want the profile created to be used for displaying targeted ads.
Gallup has taken a step to gather preliminary information about consumer preference; unfortunately, it only seems to address the vague question "is it okay if ad networks show you custom ads?" I'd really like to see a series of questions that measure habit-tracking approval as well as approval for use of tracking in OBA. Once we know this, we can figure out if people need a tool to opt-out of data collection, or if a tool to control data use is enough.
My personal point of view (not that of my employer or anyone else) is that OBA is not an invasion of privacy -- the stealth collection of data about my preferences is the invasion. Perhaps it's worth the convenience like cell phones or ez-pass toll devices, or perhaps it's not. Whether or not this invasion of privacy is acceptable should be ultimately up to you. As with many things, you can trade bits of privacy for something new. Would you like to "buy" better ads with your browsing history?
