Ask Google. This is not a WP issue.
Even better yet, Google is a competitor of WP! Shame on you! Haha, just kidding.
Draconic: not entirely untrue.
mharris: it’s very very hard to force ads to NOT target “blog”. There’s a post a while back about more specific targeting: try a site:http://wordpress.org/support/ plus keyword “targeted ads” and see if you can turn it up.
Thanks everyone for the reply’s. Even you Draconic 😉
mharris: I left out of my post that you need to use that in a google search, sorry!
I’m having this EXACT same problem on one of my blogs, but only on the index page. Once I open an article, the Google Ads are targeted.
I have another blog which returns targeted ads on all pages.
The ‘blog’ ads are getting on my nerves, so I’m hoping someone has a solution to this… 🙁
