Understand the difference between marketing/sales tactics and having a marketing/sales strategy. Less than 1% of buyers are considered now buyers. PPL require between 12 and 100+ touches before making a buying decision so it is vital that the business have a strategy that interrupts, educates, engages and subsequently offers.

Postcards, FB ads, Google Ads, Flyers, etc. are all tactics. They can all work really well. Just make sure that your message answers the question in your prospects mind and is not all about trying to get your "brand" out there. PPL are looking for answers/solutions so get in their heads and make sure your ads serve them and not you.
