About Viewershift

Viewershift measures how YouTube channels and videos grow over time. The public site shows market-level views: top lists, trending videos and reports on categories, countries and formats. Per-channel and per-video data is available to clients on request.

Where the data comes from

Everything comes from publicly visible YouTube pages: a channel's public page (name, subscriber and video counts, country and category where the channel states them) and public video pages (views, upload date, length, like counts where shown, and which caption and audio tracks exist). Our own crawler visits these pages repeatedly and stores what it sees each time. We do not use anyone's YouTube account, private or unlisted videos, or anything behind a sign-in.

Viewershift is independent and is not affiliated with, endorsed by or sponsored by YouTube or Google.

How the figures are made

Growth is the difference between two snapshots of the same public counter, so a figure is only as fresh as the latest visit to that page. YouTube rounds public subscriber counts, and so our subscriber growth carries that rounding. Where a figure is estimated rather than counted, such as earnings ranges or history filled in between visits, it is labelled as an estimate.

Coverage is broad but not complete: a channel we have not crawled is missing from every list. Each report states the snapshot it was built from and its known limits under “How this was made”, and the score methodology explains the Viewershift Score.

Corrections and removal

If you run a channel and something we show about it is wrong, or you want it left out of our public lists and reports, tell us through the contact form. Say which channel it is (a link is best) and what you would like changed. We reply within 5 working days.
