I just read Eric post on Techcrunch calling Google behavioral targeting system a bust.
For everyone who are not aware of this solution, about six months ago Google started to deploy a new version of Ad Sense which will use behavioral targeting instead of contextual targeting. This was one of these moments that tens of ad networks out there feared. In theory, if Google will start to use their vast amount of data gathered on users they should be able to win also this emerging market and take everyone else out of business.
After reading this post that claims that not many publishers opt in to use Google’ solution, I decided to use Google Ads Preference tools to actually see what profile Google built on me.
To my great surprise the answer I got is: none (see image).
Now – I’m using Google Reader on a daily basis. I’m using 3 different gmail accounts. Google is the default and almost search engine I use. I browse many sites on which Google display ads, I even updated my Google profile with my Twitter, Facebook and LinkedIn profiles.
How can it be that Google can’t understand my interests (or at least have a calculated guess)???
(And no. I did not clear all my cookies and I use just one browser).
