There is a debate in the web video production community right now on where creators should upload their content to, and if more video sharing sites equals more views and overall success.
Here are some key questions that creators must first ask themselves:
1. Do I want my content to be as widespread as possible?
2. How many video sharing sites should I upload to?
3. Do I want my content to be viewed by as many viewers as possible?
4. What is my main goal as a web video creator?
5. What are my core values and objectives?
6. Should I aim to make lots of money right away?
7. Where should I spend most of my time on the distribution side?
8. Which communities should I engage and interact with?
9. What video sharing sites are right for me and my content?
Some industry thought leaders say that creators should get onto TubeMogul and upload their videos all over the place to maximize their views. While others say that the best strategy is to upload to just a small handful of targeted sites, and engage deeply in those selected communities.
While I don't have a clear cut answer, my opinion is that early in the game creators should syndicate their content to as many places as possible, build a brand and get known, and then see which communities best respond to their content. As time goes on a natural fit should occur, and a clearer strategy will eventually reveal itself.
Whatever direction is chosen, it's vitally important that the creator has a core group of at least 5-10 viewers who absolutely love their content, and that they are willing to share, bookmark, and promote those videos to help the creator succeed.
As Seth Godin and others (myself included) believe, it's not always how many but who your audience is that really matters. If you can build trust and permission within a small audience it then doesn't become where to upload to, but rather, how can you get these people to talk about you and best spread your story.
