You need 4,000 valid public watch hours in the previous 12 months to qualify for YouTube ad revenue through the YouTube Partner Program, along with 1,000 subscribers. Shorts views do not count toward watch hours; they have a separate 10-million-views path.
Valid watch hours come from public long-form videos. Deleted, private or unlisted videos and Shorts views do not count; live streams that are kept public do. The 12-month window is rolling, so older hours fall off over time. To reach 4,000 hours efficiently, create longer videos people stay with, such as tutorials, deep dives or storytelling, and build playlists that keep viewers watching multiple videos. Live streams kept public are a strong source of watch time.
Step-by-step plan
Create long-form content between eight and 20 minutes.
Organise videos into playlists to increase session time.
Keep live streams public afterwards to count their watch time.
Improve retention by tightening intros and pacing.
Track your rolling 12-month total in Studio.
Why this works
YouTube monetization runs through the YouTube Partner Program. The full ad-revenue tier has required 1,000 subscribers plus either 4,000 public watch hours in the last 12 months or 10 million public Shorts views in the last 90 days, with a lower fan-funding tier at 500 subscribers. Thresholds and eligible countries change, so confirm the live numbers in YouTube Studio's Earn tab. Reviewers also check that the channel is original, advertiser-friendly and policy-compliant.
Common mistake to avoid
Counting Shorts views toward watch hours. Shorts follow a separate threshold.
Pro tip
Bundle related videos into a playlist and link it from every end screen. Viewers who binge three videos in one session contribute far more watch time than three separate visitors, and YouTube notices those longer sessions.
