One of the most important filmmaking strategies you must adopt in this era of modern moviemaking is a long term perspective. In years past, filmmakers focused on making one movie, selling it and then moving on to the next movie.
One secret I utilize is frequent press release submissions. Years ago, it was advised that you only wrote and submitted press releases when you had something newsworthy to say. But these days, in addition to targeting traditional news outlets, most press releases are included in search engine results. Without getting overly technical, this means for a very small amount of money, submitting one press release complete with links to your website can increase your web footprint.
