A marketing strategy is a map that gets your program where you want to go.
It gives you a plan to promote your program, target the right students and allocate your resources wisely. They say that trying to grow your program without having a plan is like going on a road trip without a map. You may get somewhere, but will it be where you wanted?
Marketing strategies are useful in any organization dedicated to generating revenue. In the case of language education, they're also useful for recruitment purposes and increasing enrollments, even if you're not expected to make money. Some people may tell you that you need a program degree or a marketing expert to prepare a strategy. While these things may help, you can outline a basic plan yourself, even if you don't have a program background or the resources to hire a consultant.
Common sense, a clear head and a vision of where you want your program to go can do wonders for helping you prepare a good, solid marketing strategy. In fact, the process of creating that vision can create marketing opportunities you would otherwise miss, simply because you are able to clearly describe your program anywhere, any time.
