AdSense not serving contextual ads

[Giano]

Hi there.
I'm experimenting since a week a strange issue: in some parts of my site AdSense is serving non-contextual ads referring to "blog" keyword mainly).

Till today I never had this problem and immediately contacted Google to have support.
After 2 days of work they said this is a known issue engineers are working on.
Actually a whole week passed without any news from them.

Anybody is suffering this also?

Thank you

I had same issues. Currently I am testing one of my chanels with section targeting. It seems to be working so far. It takes a long time before you'll see effects (couple of days in my case) If things stay fixed, I will go ahead and fix couple of other areas on my site.

Till today I didn't had the need of section targeting.
Everything worked perfectly.

I don't understand what's goin'on but is something big since I continue serving "blog ads" and many times even blank ad blocks (not even the public service Google ad).

I'm very upset...The problem isn't not earning money but serving a wrong, non-contextual ad to my readers. Which is absolutely what I don't want to do.

Thanks for your answer.
