YouTube videos that dominated the charts in Italy 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 Italy replaced an average of 47% of its entries every day, moving between 33% and 60% 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 8 consecutive days: Ho trovato tutti i SEGRETI del trailer di HARRY POTTER! | Analisi & Teorie della Serie TV HBO. 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 ME CONTRO TE - MERAVIGLIOSA (Ti Amo Sofia) | Canzone Ufficiale, up 27 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.
