I don't know if this is related, and I haven't been able to find any information on it anywhere. I just accepted a $100 Adwords credit offer from Google. Shortly after I did that, roughly 80% of the ads I have placed on my site are ads for Google Adwords. Completely irrelevant to my site and its content.
Is it possible the two are related? My sites have been displaying relevant content for years now, why the change? Any feedback on this would be appreciated... Thanks
