There are several ways to increase your social media video subscribers. Use video SEO to make it easier for target audiences to find your videos. Include attractive custom thumbnails to make your videos more enticing. Use end cards and annotations to include calls to action asking viewers to subscribe. You can also promote your videos on your website, landing pages or blog posts. And you can use influencer marketing to spread the word about your video content and gain new subscribers that way.
Viral marketing is any marketing technique that induces websites or users to pass on a marketing message to other sites or users, creating a potentially exponential growth in the message's visibility and effect. A popular example of successful viral marketing is Hotmail, a company now owned by Microsoft, that promoted its services and its own advertisers' messages in every user's email notes.
According to a paper by Duncan Watts and colleagues entitled: "Everyone's an influencer", the most common risk in viral marketing is that of the influencer not passing on the message, which can lead to the failure of the viral marketing campaign. A second risk is that the influencer modifies the content of the message. A third risk is that influencers pass on the wrong message. This can result from a misunderstanding or as a deliberate move.
