There are a number of things you need to consider when you’re trying to decide whether to market your book yourself or hire someone to do it for you. I often hear authors tell me they had no idea how much time, energy, and money it would take to market their books. It’s a full-time job. I’m sure most of us know how easy it is to think you’re going to do some basic research on the internet for half an hour and then look up at the clock and realize you’ve been at it all afternoon. If you have a lot of time for that sort of thing, then maybe marketing your own book is something you should consider. Or if you have experience as a marketing professional and understand how to get your own media contacts, what a good professional press release looks like, and so on, then doing your own marketing may be a good choice to you. But if you don’t have that time or experience and you can afford it, hiring a professional is almost certainly the best way to market your book and to see if it resonates with the target audience. So consider time, consider experience, and consider how much money you’re willing to devote to the project, and then make your decision.
