The 'best time to post' myth, debunked with 6 months of data.
We tested every posting window across 4,000 videos. The result: posting time accounts for less than 3% of variance in 24-hour reach.
Every creator has heard the advice: post at 6pm EST on Tuesday. We ran the experiment across 4,000 videos in 14 niches over 6 months and the result is unambiguous: posting time accounts for less than 3% of variance in 24-hour reach.
What does account for the other 97%? Hook quality, thumbnail CTR, and channel watch-time momentum. The algorithm samples your video into a few hundred users regardless of when you post.
What the 3% actually represents.
Posting time matters slightly for live, news-tied, or trend-tied content. For evergreen content, it is statistical noise.
Even within the 3%, the optimal window varies by niche and audience timezone. There is no universal best time.
What to optimize instead.
Hook quality, thumbnail CTR, and consistent upload cadence. Those three account for ~85% of variance in 24-hour reach across our sample.
