Comment on Google AdSense Ad Channels by Andy.

Google AdSense Ad Channels Hi David

I have a question about targeted adsense ads on the homepage. If you go over to my website you will see that the adsense ads served are related to ‘Reading’ rather than general hobbies which I was expecting. I have just one article (a static page) as my front page entitled ‘Hobby Ideas .. everyone needs a hobby’ and my article is targeted to the Hobby Ideas keyword.

I have done some experimenting and found that if I use the exact same content/article on an inner page and/or post then targeted ads show up. Therefore targeting is working fine on inner pages but not on the homepage even though the article is the same. Any ideas why this night be?
