1. Think Long Term.
You need to develop a marketing strategy that focuses on long term goals. Becoming a "name" isn't going to happen overnight. Selling 10K books this month isn't just going to happen either unless you do something different. Be patient and begin by writing some achievable goals designed to help you increase your name recognition and public awareness of your brand.
2. Know your brand.
Yeah, you there. What is your brand? What kind of writing are you known for or want to be known for? You need to give a lot of thought to this because it's virtually impossible to market yourself and/or your work unless you know what your product is.
3. Increase your visibility.
You must be noticed. No one will want to find your books if you sit quietly in a corner. Investigate low cost ways that make a big impact. Write articles, book reviews, blog, comment, speak up, Tweet, Facebook, attend writers club meetings, network. There are thousands of ways to get noticed online. Figure out what you can do that's just a step out of your comfort zone. You see, you have to step out of your comfort zone to grow.
If you're not satisfied with your sales numbers or your career growth, you must do something different because if you keep doing the same old thing, you'll keep getting the same old results.
