One of the things I like about the folks who run Voices.com is that they are always working to raise the entire voiceover industry to a higher level. In particular, they prepare tools for folks who are relatively new to the world of voiceover (both those who wish to be voice talent as well as those looking for a voice) to offer guidance about how to move forward.
Their latest offering is called the Internet Marketing Plan for Voice Actors and is available as a PDF file on their site. While it’s not perfect (there were a few typos, for example), this ebook will help you think more clearly about how to move forward with your own online marketing.
