General advertising rules apply to social media advertisements. In addition, you must make sure it doesn't become a lottery. Also, each state has different requirements for lotteries and sweepstakes, so you need to check your state specific laws.
(2) The term "lottery" includes any arrangement, other than a savings promotion raffle, whereby three or more persons (the "participants") advance money or credit to another in exchange for the possibility or expectation that one or more but not all of the participants (the "winners") will receive by reason of their advances more than the amounts they have advanced, the identity of the winners being determined by any means which includes--
(A) a random selection;
(B) a game, race, or contest; or
(C) any record or tabulation of the result of one or more events in which any participant has no interest except for its bearing upon the possibility that he may become a winner.
(3) The term "lottery ticket" includes any right, privilege, or possibility (and any ticket, receipt, record, or other evidence of any such right, privilege, or possibility), of becoming a winner in a lottery.
(4) The term "savings promotion raffle" means a contest in which the sole consideration required for a chance of winning designated prizes is obtained by the deposit of a specified amount of money in a savings account or other savings program, where each ticket or entry has an equal chance of being drawn, such contest being subject to regulations that may from time to time be promulgated by the appropriate prudential regulator (as defined in section 5481 of this title).
