AdSense Behavioral Targeting Fail

Why Behavioral Targeting Doesn't Work

[jetteroheller]

I started searching for a printing company August 2013

I started printing in December.

They delivered the books printed in China middle February to me.

Now are 2500 from 3000 printed books in my basement.
But what ever side with AdSense I visit,
I always see only ads from printing companies offering to print my book.

I think you found a bug in the Behavioral Targeting system. They're not adequately taking into account that the sale has happened and that another sale is not likely. It's the last part that Google needs to better understand, to work out which sales are not likely to repeat.

God that happens to me all the time. Has been that way for quite a long time now, and I'm sure I've mentioned it here often.

Every so often I'll search for "Blue Widgets+ebay.au" which works for me. I'll likely buy that day.

For weeks thereafter, no matter the topic of sites I visit - I'll see ads for "Blue Widgets".

Two years ago, I searched some College Courses for a grand-daughter. Yep on certain types of sites I still see ads for all manner of College Courses [remotely unrelated to the site content].

I sometimes wonder if the owners of those sites have disappointing CTR?
