As far as I know, Adsense is more about contextual targeting than about behavioral targeting. So it’s both targeting, but each a different type.
I don’t understand.

In Brazil it seems that all websites show basically the same ads, this must be due to the fact there are not a lot of companies advertising using adwords on the content network.

I never click on any Adsense for the simple reason, Google will spend an enormous amount of effort make sure search results are relative to the page but the Adsense is not looked at this way. I have in the past clicked on an Adsense ad that was on a page I was browsing for Web Development. 3 out of the set of ads had nothing to do with the subject. They were just placed there because there was a link at the bottom saying web development by ”******”.

They may have changed the way they do things but I wouldn’t trust that every click you pay for is going to account for anything.

This automatically makes me think that behavioural targeting is just a fancy way of Google trying to say they know the behaviour of the person behind the mouse when this is absolutely impossible. And after witnessing first hand how inprecise they are with targeting ads I would have to say absolute BS.

However, I do think contextual targeting is powerful as well. I just think Google is a long ways of getting it right.

But what if the advertiser is selling Coca-Cola? They might like their ads to show if I’m a teenager, or if I’ve ever visited a Pepsi page.

Come to think of it, even someone who is selling Simpsons merchandise might pitch their ads differently if I’m a person who regularly buys clothing online, as opposed to a person who buys geek gadgets.

So, I think there’s room for content targeting and behavioral targeting, even sometimes at the same time.

PS: Maybe you posted this when you heard rumors that a competitor was about to launch behaviorally targeted ads

Well I did some reading on this one,… and I hope I learned at least something from it. Here´s my take at it:

As far as I know, Adsense is more about contextual targeting than about behavioral targeting. So it’s both targeting, but each a different type.

Hydrogen bonds are a form of intermolecular forces and so are van der Waal’s forces. So they´re both intermolecular forces, but each a different type.

I have to say your comment is outstanding. I personally see a connection between science and google algorithms. Not only math wise, but chemistry also. Amazing!

I do not know if there was anyone above that mentioned that H-bonds are only on some selected molecules. Usually those with Hydrogen and in many cases with Oxygen and Nitrogen. Not every molecule can H-bond with each other.

Van Der Waals is on every molecule.

Aside from having Adsense being a strong bond with website content as behavioral targeting is taking note of what a person is doing, where this can simply be interacting with everyone, relevant or irrelevant, irregardless of the content.

And since h-bonds and vdw are both IMF and are not really real bonds like Covalent and Ionic bonds, these can easily break off physically if needed. The same way Adsense can easily kick you out if needed. Covalent and Ionic bonds usually need separation by a chemical means since this is already a compound. h-bonds and vdw are just formed in mixtures you can separate in many cases even with a porous filter. Adsense can do that too, with their semi-permeable membrane spam-MFA filter
