Hi, This may be an old trick, I am trying this in new way.But I am afraid, if it against adsense TOS. I have a movie related website, where I was getting nearly 300 to 500 impressions and nearly 20 to 50 clicks per day, but I had just earned 0.30 to 1.00 $. Now I have displayed Finance, Medicare, Loans and other similar google top payed words related articles using Google News RSS. Now I am getting low number of clicks and high revenue. Is this trick against adsense TOS?
Are the ads providing any value to your visitors? Are they relevant? It does not matter weather it is against the TOS or not. Always think about your visitors first.
I am not sure if it violates the TOS but I see you turning off your visitors because of the articles do not relate to the niche. It is better to put up more related content and build traffic. JMO
