First things first: If your offer isn’t right for someone or if it plain stinks, your opt-in rate isn’t going to be magically propped up with a few tricks. But if you have a good offer and qualified traffic, maybe these five tactics can help: 1) match the offer with the medium; 2) offer less than you think you should; 3) reduce form fields; 4) turn your call-to-action into a give-the-payoff; 5) use a squeeze page (but only if they’re trying to get to your home page).
