How YoTrend measures YouTube trends

Current video lists originate from the YouTube Data API ranking for a specific country and category. YoTrend currently tracks Morocco, France and the United States across music, gaming and entertainment categories.

A stored ranking is linked to its country, category and UTC capture time. Video titles, channel names, thumbnails and public engagement totals may also come from YouTube.

The scheduled production capture runs once per day. Each successful run stores a dated snapshot; the interface displays its age and warns when it is older than expected.

If stored data cannot be read, YoTrend may display a live YouTube API fallback. That fallback is labelled Live YouTube data and does not receive invented historical signals.

Movement is the previous stored rank minus the current rank. A positive number means the video climbed; a negative number means it dropped. Stable means its rank did not change.

New entry

The first stored observation for that video in the selected ranking.

New peak

The best numerical rank reached across stored observations.

Days trending

The number of UTC calendar days represented by stored observations, not continuous watch time.

Trend score

A deterministic summary of ranking position, movement and available history. It is not a forecast.

YouTube rankings can change between captures. A missing observation does not prove that a video stopped being popular, and country rankings do not represent every viewer in that country.

YoTrend does not claim that ranking position is equivalent to total popularity or virality. When data is unavailable, the site shows an unavailable state rather than generating substitute rankings.
