YouTube у цифрах: звіти з даними

Ми щохвилини оцінюємо відео YouTube за тим, скільки вони навчають, і розповідаємо, що показують цифри по бібліотеці навчальних відео. У кожному звіті вказано дату й методику, а його цифри зафіксовано на цю дату.

    57%of a typical explanatory video's runtime is the part worth playing.

    How much of a YouTube video is actually worth watching? We measured, minute by minute

    We scored every minute of a library of learning videos. The median video earns 57% of its runtime, the first and last tenth earn least, and the title predicts a skip.

    The best YouTube channels for learning, by subject: measured video by video (2026)

    The top three educational YouTube channels in each of 16 subjects, ranked by the median score of their measured videos, and why even the best channels are not gold every time.

    A chapter list tells you where things are, not which one is worth watching

    Section by section across the library. The parts a chapter list would call content vary by 34 points inside a single video, and length barely predicts which is which.

    Does a longer video teach you more? We checked, and the answer is yes

    Measured depth rises by 31 points from the shortest videos to the longest, holds inside every subject we can test, and buys less usefulness than you would expect.

    Shelf life: how long the material in a video stays true, by subject

    Measured shelf life runs from 84.8 in science to 37.9 in tech news — a 47-point gap. Runtime does not predict it and neither does difficulty. Subject does.

    The eight-minute pile-up: where runtimes cluster, and what it costs

    Runtimes pile up the moment a video passes eight minutes. The pile is real and easy to see. The penalty everyone assumes comes with it is not.

    Do YouTube titles tell the truth? Honesty measured across twenty subjects

    Average title honesty is 81 out of 100, from 87 in science down to 73 in travel. The same subjects that oversell titles also carry the most padding.

    How long is a lesson, really: runtime measured across twenty subjects

    Median runtime runs from 18:16 in history to 9:30 in productivity, nearly two to one. It has almost no relationship to which subjects score highest on value.

    We measured twenty subjects. Three percent of the videos were advanced.

    Three percent of the videos we measured were pitched above intermediate. Here is which subjects have none at all, and the one signal that finds the rest.

Ці звіти використовували старішу версію нашої шкали. Їхні цифри лишаються такими, як були; актуальні дані — у звіті How much of a YouTube video is actually worth watching? We measured, minute by minute.

    Sponsor reads take 1.6% of the runtime. Padding takes 40%.

    One in five measured videos carries a sponsor read, and it runs about sixty-seven seconds. The thing that actually spends your time is somewhere else entirely.

    Which subjects are worth your time: measured value across twenty subjects

    Science scores highest of twenty measured subjects at 66.9; travel lowest at 38.4. The same subjects also carry the least padding and the most honest titles.

    Runtime is a useless filter: longer videos carry less padding, not more

    Padding falls from 45% under ten minutes to 28% over an hour, and measured value rises the same way. Picking the shorter video is, on average, backwards.

    The shape of a YouTube video: every value curve overlaid

    Average measured value climbs fast, holds through the middle two-thirds of a video, then falls sharply near the end. Here is the curve, averaged across the library.

    One in five measured videos was not worth the time it asked for

    One in five measured videos was not worth its runtime. The share runs from 5% in science to 64% in travel, and the title predicts it before you click.

    We measured the padding again, on a larger library. The number has not moved.

    A second padding census, on a larger set of measured videos. The median is still 40%, the set has grown by three quarters, and the distribution barely moved.

    The useful part of the median measured video starts at 1:02

    Across the videos we have measured the useful part starts at 1:02, and one in ten makes you wait past 3:47. Here is how that splits across twenty subjects.

    We measured YouTube across fifteen categories. This is how much of it was filler.

    A padding census across fifteen categories: the median video is 40% structure, and the long ones are the least padded, not the most.
