Hi, thanks for that ryndre and fashionsappeal. It can be worthwhile using different video syndication channels. I find that YouTube has a much greater effect on traffic and views to videos than Vimeo and Dailymotion do (even combined). And what with Vimeo becoming more of an art video forum it makes it difficult to upload other types of content. Sharing channels have become increasingly less fertile for video marketing because of the consolidated strength of YouTube. It's the third biggest social network and second biggest search engine, Google retreives video from YouTube in search as rich snippets above other players (if the videos are the same) and its the first place to go for video. Most of the traditional video syndication channels have turned away from hosting brand content and lean towards curated content instead for the reasons above. In my opinion it depends on the type of video content that you're posting as to where to put it, but if it's a brand awareness video YouTube wins all the time.
As for sharing on social media, I was more interested in how framing your video (in terms of copy or by A/B testing different images) or using techniques like PPC might be best used to make your simple instructional video reach the most people it can. Also I was interested in the differences between say, Google+ and Twitter. Both can share video, but the audiences are different. I like to use a combination of hashtags and @mentions to target users and audiences on Twitter, but often find Google+ to be devoid of audiences when it comes to certain sectors. It's especially difficult for brand awareness videos where the focal point is the video content (rather than informational content). Conversely, Facebook is great for video content and can dramatically increase shares.
How do you both 'frame' content when you're posting on social sites?
