The Problem With Contextual Targeting
In principal it sounds like such a good idea. Read the words on a page and run ads that fit contextually with those words. In practice, it often doesn’t work or worse, the context backfires.
A good example is the post I did on Firefox popups. I was commenting/complaining about a popup ad for a Panasonic product. If you read that post in an RSS reader, you got an ad for a Panasonic product.
I doubt that’s a context Panasonic would be happy with. And I am not so happy with it either.
