If I advertised a bit on sites like CNN and Fox, and chose to put those logos on my website saying: "As seen on CNN and Fox News"...this would of course be legal. But would you get any trouble from Google's policy team? Would they want you to send in proof of where you have been mentioned on these sites and could you get a ban for doing something "unethical" like this?
Give it a try. Seems like a good 'trust-building' strategy. Whats the URL of your site?
