How the YouTube algorithm works
YouTube is won on thumbnail/title click-through-rate and average view duration. Hook retention in the first 30 seconds, keep titles to 40-70 front-loaded characters, and use Shorts as a discovery funnel into long-form.

Where these numbers come from. These are the numbers Content Drifter schedules and formats YouTube posts against. They are our editorial estimate from public reporting and our own publishing, not something YouTube announced.
How the feed is assembled
In our YouTube model, comments count for 2 likes, then shares and reposts at 1.5 and saves at 1. Bars show multiples of a like.
- Comments2x a like
- Shares and reposts1.5x a like
- Saves1x a like
- Likes1x a like
The first-hour cliff
YouTube is checked 120 minutes after a post goes out, 60 minutes after the first hour ends.

Our model treats a post below 50% of your own median engagement by then as stalled. Comments and shares count most in that window.
Best posting windows
Our YouTube curve has 4 posting windows across 4 days, led by Friday 13:00 to 15:00 UTC at 2.25x a median hour. Monday, Tuesday and Wednesday have none.

Posting cadence and cooldowns
The queue holds YouTube to 2 posts a day and 10 a week, at least 12 hours apart. Seven days at the daily ceiling would be 14, so the weekly cap of 10 is the one that binds.

How Content Drifter applies this to your YouTube posts
Each row pairs one of the YouTube numbers above with what the product does about it.
YouTube engagement peaks around 13:00 to 15:00 UTC on Friday, roughly 2.25x a median hour.
An unscheduled post takes the next open peak slot in your timezone. On Pro and up those slots are ranked against this curve and your own posting history.
Best time to post schedulingShort outperforms long-form video by about 50% on YouTube.
Generation writes for the formats that carry a lift on YouTube, not one body cross-posted everywhere.
Per-platform publishingOn YouTube, a post below 50% of your median engagement at minute 120 is read as stalled in our model.
On Business and Agency plans with the boost engine switched on, we run that check at minute 120 against your own median, so a stall surfaces while it can still be acted on.
The algorithm-aware enginePosting more than 2 times a day, or inside 12 hours of your last post, works against you on YouTube.
The queue honours that spacing when it assigns slots, counting posts you already published as well as ones you have queued.
The queueYouTube posts land best between 40 and 70 characters, against a platform limit of 5000.
The pre-publish check names the rule a post breaks instead of handing you a score.

YouTube algorithm questions
What is the best time to post on YouTube?
Our strongest YouTube window is 13:00 to 15:00 UTC on Friday, about 2.25x a median hour, then 11:00 UTC on Sunday. Times are UTC, and the queue converts them to your timezone.
What does the YouTube algorithm reward most?
Comments carry the most weight, about 2x a like in our model, then shares and reposts at 1.5x and saves at 1x. YouTube is won on thumbnail/title click-through-rate and average view duration. Hook retention in the first 30 seconds, keep titles to 40-70 front-loaded characters, and use Shorts as a discovery funnel into long-form.
Do links hurt reach on YouTube?
No. A link in the YouTube body carries no modelled reach cost, so yours stays in the post body.
How often should I post on YouTube?
The queue holds YouTube to 2 posts a day and 10 a week, at least 12 hours apart. Seven days at the daily ceiling would be 14, so the weekly cap of 10 is the one that binds. The queue applies those caps on your own calendar day, not UTC.
Which post format performs best on YouTube?
Short carries the largest lift on YouTube in our model, roughly 50% above long-form video, ahead of thumbnail-optimised upload at 20%.
How long should a YouTube post be?
Between 40 and 70 characters; YouTube allows 5000, which is where we stop you. Hashtags work best at 3 and start costing reach above 5; the publisher accepts up to 15.
How soon can I tell if a post is working on YouTube?
Minute 120. Our model reads a post below 50% of your own median engagement at that point as stalled, and comments and shares count most.
