YouTube videos that dominated the charts in Poland over the last 7 days.
The weekly ranking measures consistency over time - every hour spent in the top charts counts. A single-day viral spike carries far less weight than a video that dominates for several consecutive days.
How fast this chart renews itself
Over the last 7 days, the ranking in Poland replaced an average of 41% of its entries every day, moving between 30% and 54% depending on the day. That is a chart with real inertia, where a successful video is still there several days later. This figure comes from comparing our own daily snapshots: YouTube publishes the ranking of the moment, never how much of it survived since yesterday.
The chart carries about 50 entries a day, filled by 50 distinct channels, so almost every slot belongs to a different publisher. Concentration only appears when one channel places several videos at once, which is exactly what the ranking above lets you check.
The most resistant video of the week held on for 10 consecutive days: Zapach. Survival time is a far better measure of a video's strength than the position it opened at, because it is the only one a launch budget cannot buy.
The sharpest climb belonged to Beautiful (DJ A.N.G.E.L.O Remix), up 20 places in a single day. A jump of that size in twenty-four hours almost always signals an audience arriving from outside YouTube rather than gradual discovery.
