In our previous case study about explainer video length, we researched the correlation between an explainer video’s length and audience retention rate on our YouTube channel. We found that:
Explainer videos of 1 minute or less in length have an average audience retention rate of 77%
Explainer videos between 1 and 2 minutes long have a 57% audience retention rate.
Explainer videos that are between 2 and 3 minutes, and more than 3 minutes long, have 47% and 40% audience retention rate, respectively.
