The problem is that you think about marketing from the end rather than from the beginning. Spending money with FB or Google is one possible end. Another one would be inbound / content marketing. Another one would be trade shows. Etc. However the beginning of marketing is researching how your product interacts with the market, which problem your product solves and for whom. A lot of times who you think your customers are isn't really who your customers are and why you think they buy your product isn't really why they buy it. And many times your product is capable of solving a problem for a much larger user group which however you just don't know about yet (but should definitely find out about). Getting all these variables right is how marketing starts and besides your own time it doesn't cost you a dime. Once you have better knowledge about the market (who you target, at which price point, with what message, etc..) you will have a much better feeling on how to target that market and spending actual dollars on a marketing end (ads etc.) at that point will feel much more satisfying and less "voodoo".
