Real Time Bidding: Auctioning off Your CookiesHave you ever paid much attention to the ads that pop up on your computer while you are browsing, and thought WOW! That’s crazy, I was just looking at that car, watch, website…. etc and now there’s an ad!? What a coincidence! However, in the case of online advertising there is no such thing as a coincidence. Its real time bidding: a sneaky and brilliant technology. Nearly 97% of American internet users are subjected to Real Time Bidding (RTB) every single day . For many people it is considered an invasion of privacy and but for most its not considered at all, as they are unaware of it's existence and the powerful role it plays in our online clicking and buying.
What is it?
The goal of RTB is to ensure that a company's ads are seen by the consumers that are most likely to respond; Hence increasing their sales . But how do they know? Information such as topics you Google, sites you visit often, ads you click on, and the cookies from websites you've visited that are stored on your computer are collected by companies, such as BlueKai, and then the fastest auction ever occurs. It is a relatively simple concept with not-so-simple algorithms that enables advertisers to bid on the advertising space on the web page your are looking at within 100 milliseconds!
Check out this video from Google for a pretty simple explanation. 
This is how CrowdScience.com explains it:
Here’s a simplistic example of how real-time bidding (RTB) would work in the real world: A user spends a lot of time on financial websites, checking stocks and looking up Morningstar ratings. They arrive on a webpage that uses Real-Time Bidding to serve ads. On the back end, a major financial services provider has specified that they are interested in users that like stocks. A luxury carmaker has also indicated interest in this audience. The RTB system matches these advertisers with the user profile and they bid on the ad. Whoever has the highest bid wins, and their ad gets served. 
Advertisers love it, by 2017 revenues generated from RTB will be more than $7 Billion! ; but lets also consider the people whose cookies are being auctioned off, and how to control what information about you is out there.
Controlling your Online Identity
Controlling your Online Identity
Jeffery Rosen from the New York Times wanted to test his online presence and he did so with a very simple experiment. First he cleared the cookies from his two internet browsers. Secondly, he started creating two very different Jeffs; 1) Republican Jeff and 2) Democrat Jeff. He did this by spending time on such sites as Mitt Romney's campaign site on one browser, as well as Obama's re-election site on another browser. He then ventured off to his favorite websites within days the ads on the site had changed to reflect the browsing history of that specific browser! See the Full Article
The work of Real Time Bidding!
Some may find this a little creepy and intrusive to your privacy. For those that feel this way there are a few things you can do. One being as easy as clearing your cookies in your browser often, and another would be by either to Register or Opt Out with BlueKai (an online big data marketing service that provides 1st and 3rd party information) This is not the only company out there that does this but it’s a great place to start. Registering allows consumers to see what information is being logged by 3rd party sources.
Real Time Bidding is a tremendously powerful tool that is here to stay. So, you can either take the time to manage it, as mentioned above, or accept the fact that your browsing history and cookies are out there at the disposal of the highest bidder.
