So you've got some efficient, effective, informative videos uploaded to YouTube but no-one is watching them. Here's a helpful article on how to boost some subscribers to your online video campaign.
"When someone subscribes to your YouTube channel, they will see all updates to your channel on a personalised feed. Subscribers represent a stable audience base with an active interest in your videos. This type of engagement enables viewers to feel part of a community in which they can interact with like-minded people and the makers of the videos themselves.
Subscribers are likely to be genuinely interested in your content. They are more likely to recommend you to others as a result."
