There are a lot of posts here that discuss the importance of producing good quality videos, and a great deal of posts that address the importance of SEO. Since I started on youtube I have been trying to understand SEO and "tweaking" my channel, and was recently in a position to measure it's importance in a tangible way: The company I work for has a sizeable marketing budget and is a major player in the yachting industry. They have a youtube channel, but they have really never done anything to build it or optimise it in any way. They published my last two videos on their channel at roughly the same time as me, and the difference in results is astounding: VIDEO 1 (posted 1 week ago) - Their channel 40 views - My channel 2,102 views. VIDEO 2 (posted two months ago) - Their channel 133 views - My channel 99,275 views In my opinion many businesses don't use youtube videos as a primary marketing tool because they have not seen instant results in terms of a high view count and enquiries. This is in spite of the fact that a) they know that youtube is the second biggest search engine in the world, and b) everybody is telling them that video is the most important online medium. The above is a very clear indicator that it is not enough just to produce quality material and cross your fingers in the hope it will go viral. You have to also care for your channel, tweak it, and constantly improve it in order to get the best distribution possible. It seems like a terrible waste of time and money to produce promotional videos if you do not put the effort into the channel that is used to distribute them. I know that most YTT members produce videos that are for entertainment rather than to promote a product or service...but the principle still holds true: Look after your channel!
