After an in-depth study (a joint effort of TubeBuddy and HEY.com), authors Dane Golden and Phil Starkovich have found that saying the word “you” just once in the first 5 seconds of a YouTube video can increase overall views by 66%. And views can increase by 97% – essentially doubling the viewcount – if “you” is said twice in the first 5 seconds (see table on page 22 of the study).
And “you” affects more than YouTube views. They also learned that simply saying “you” just once in the first 5 seconds of a video is likely to increase likes per view by approximately 66%, and overall engagements per view by about 68%. Get the study.
