ZEFR’s 20 Under 21: The Top Digital Video Influencers

What is social media “influence”?

There is, in fact, a metric by which to measure it with accuracy, but not enough media experts know how to do it. In the old model, viewers drove television ratings, so the show with the most viewers would reap the windfall of the most advertising dollars. The math was simple. Now, media is social. That is obvious enough to most people, so why do analysts continue to lean on the old model and simply add up followers or subscribers when talking about social media celebrity and influence?

At ZEFR, we value engagement over the simple math. We tracked and ranked the trending engagement of some of the top digital creators under the age of 21 across thousands of data points to find out just who wields the most influence on the web.

ZEFR’s trending engagement data is a proprietary projection of how much fan interaction an influencer will drive on future posts, which is derived from a recency-weighted average engagement on each channel, corrected for outlier posts and adjusted for the upward or downward trend of engagement on the channel.

As we’ve said before, engagement is everything. Viewers and followers might lead you to the next celebrity, but if no one is engaging with that creator’s content, well, then all you have is fame without influence. With all of this (and more) in mind, ZEFR Insights presents 20 Under 21, the top social media influencers ranked the right way with the right data.
