Stupid RTB Tricks

At BLOOM we’ve been integrating real-time bidding functionality and have been running campaigns through AdGear since November 20o9. We’re plugged in to the DoubleClick AdX 2.0 and although our volume there is relatively small compared to the “traditional” third party delivery, it’s been a lot of fun.

To anyone dealing with the sheer scale enabled by RTB, it ends up being a boundless source of ideas for very questionable practices. This, in turn, raises the issues of privacy and data ownership. There has been a lot of coverage of RTB, and of course AdExchanger has done an amazing job in covering the new generation of ad companies (including us!). But let’s talk about the dark side of RTB.  The Stupid RTB Tricks. Media hacking.

1) Browser history retargeting.  Imagine that you have a two-sided display campaign. On one end, you run on sites or networks bought direct, with huge reach. Everytime you serve an impression, you check user’s browser history (see a demo of the CSS trick here). What you check for are your advertisers’ competitors’ sites.  In the second part of the campaign, you retarget those who have visisted your competitors’ site with a sweet call to action.

2) Über-browser history retargeting. Adding on top of the first trick — create a segment for those who have visited more than one of your competitors’ sites. This might indicate that the person is in a serious shopping mode. Since browser history CSS trick works based on actual URLs and not just top-level domains, you could go really deep inspecting which products on your competitors’ sites were looked at. Targeting this segment through RTB is a no-brainer — bid like you’ve never bid before.

3) Using premium media as audience qualifiers. Buy a direct campaign with a premium publisher that reaches a very valuable audience. Say, WSJ. Run the campaign with frequency cap of 1. Reuse this data to serve to the same exact audience across the RTB universe. Do so for more than one advertiser, compensating the original advertiser whose budget went to WSJ.

Of course, there are many more opportunities of this sort.  And although there is nothing really new here, having the possibility of doing it “on tap” without necessarily having a huge scale in the retargeting segments is definitely new. You don’t need to setup anything special with ad networks and run 10 witnessing tags from 10 of them, don’t need to commit ad budgets for retargeting without knowing what the final reach will be, etc.

I’d love to see other people post more examples of media hacking (both in the good and bad sense of it).
