So back to the nfl teams.. I could have articles and promote the article or do you mean a tangible product?
Greetings everybody, adwords and adsense are both conceived by the same Google. The idea is to provide the best experience to the user by helping them reach the right audience. For adwords the rule of thumb "If you were the user, what experience would you have on that particular page from that ad?" So; 1) Adsense is allowed on landing pages. 2) They should contain something relevant to a topic. Not just some page clogged with adsense ads because Google hates that and eventually you would be penalized for it.
