SEO is a Google invention anyway, so it's not unethical to manipulate the rules at will (if you're able to) to gain an advantage. It's their rules anyway, so if a method works, it's acceptable by default. That said, if the work requires actually hiding useful news or unconvenient events, that's more of a grey area. Dark-grey, actually. "Mama's got bills", as they say, so keep doing it until you'll hopefully find a better job. I'm assuming refusing to do it, while keeping your position, is not an option.
