The set-up

No new videos needed. For every upload the channel already has, log its views at day 2, day 7 and day 28, then rank the uploads at each point.

What is measured

How long: Runs alongside everything else

How to read this

Every result on these pages comes from one channel, published by the person who owns it, from their own YouTube Studio. Results are never combined across channels. A handful of videos on one channel is an experiment, not proof.

Test it on your own channel

Nothing to tag. VideoCore lines up every upload you have at day 2 and day 28.

VideoCore reads only your channel’s own YouTube Analytics, and only you see it. Comparisons with your typical video are calculated by VideoCore from your YouTube Analytics; they are not YouTube figures.

Do this: run M3 on your channel (you’ll need to be signed in with your channel connected).
