The vocabulary creators run into when they start comparing videos: what an outlier multiplier actually divides, why a baseline is a median, which numbers are public and which stay inside a channel's own analytics. Every definition stands on its own, and each one links to the guide that goes deeper.
Audience retention is the share of a video still being watched at each moment, reported in a channel's own YouTube Studio analytics. It is private to the channel owner, so outside research can observe a video's views and packaging but never its retention curve.
Read retention dips and spikesA breakout video is an upload that reaches far beyond its channel's normal audience, usually because the idea or the packaging pulled in viewers the channel had not reached before. In Vidfora it is simply a video with a high outlier multiplier against its own channel's median.
How to find YouTube outliersThe channel median baseline is the median view count of a channel's other mature videos in one format, and it is the denominator of Vidfora's outlier multiplier. A median is used rather than an average so that one past breakout cannot drag the baseline above the channel's real normal.
The outlier score formulaClick-through rate is the share of impressions that became views: how often people who saw a thumbnail chose to watch. YouTube reports it privately in Studio. There is no universal good number, because it depends on where the impressions came from and who saw them.
What is a good YouTube CTR?A content gap is a viewer question that existing videos answer poorly, partially or not at all: a missing constraint, a weak demonstration, outdated instructions or an overlooked experience level. A gap is only useful when it changes what you would actually film, not just which keyword you target.
Find the unanswered questionThe hook is a video's opening, often discussed as its first 30 seconds, where a viewer decides whether the promise made by the title and thumbnail is about to be kept. A strong opening confirms the promise and begins the work rather than restating it.
Write an opening that starts the workAn impression is one time YouTube showed a video's thumbnail to someone on the platform, in the home feed, search results, suggested videos or elsewhere. Impressions are private channel analytics, and a low count has many possible causes rather than a single diagnosis.
Diagnose low impressionsAn institutional channel is one whose reach comes from being an institution rather than from craft: a corporate newsroom, a television brand, a studio, a record label or a megastar artist. Vidfora suppresses a curated list of them from default rankings, since their spikes teach a creator nothing.
Inside the outlier databaseIn Vidfora's scoring, a mature video is one at least 30 days old, by which point most uploads have collected the bulk of their first-month views. Only mature videos are trusted as baseline peers, and younger videos are scored against a baseline scaled down for their age.
Why 30 days mattersThe niche opening score is Vidfora's 0-100 read on how much room a topic has, built live from the top YouTube results for it. It weighs median views against channel size, the share of small channels winning, and how fresh the uploads are. Verdicts run from Wide open to Saturated.
How Niche Explorer scores a topicA YouTube outlier is a video whose views far exceed the median views of its own channel's other mature videos in the same format. Vidfora treats two times that channel baseline as the threshold, with Shorts and long-form pooled separately.
How to find YouTube outliersThe outlier multiplier, also called the outlier score, is a video's views divided by its channel median baseline for the same format, with the video itself left out of that baseline. A 7x multiplier means seven times the channel's typical result for that format.
Definition, formula and rangesPackaging is everything a viewer sees before pressing play: the thumbnail, the title, the duration and the channel name. It is what an outlier study can observe directly, since the promise is public even when the retention and click-through numbers behind it are not.
Design a thumbnail that readsCPM is what advertisers pay per thousand ad impressions before YouTube's share; RPM is what the channel actually earns per thousand video views, across every revenue source, after that share. RPM is the number that describes your income; CPM describes the ad market around it.
A worked revenue scenarioA saved board is a named collection of videos you have kept for one project or question, so that packaging research sits together instead of scattered across a feed. Vidfora boards can be viewed as thumbnails only and shared as a link with an editor or designer.
How saved boards workSearch intent is the task a viewer hopes to complete with a query, not the words themselves. They may want to learn, fix, compare, decide or explore. Similar keywords can hide very different expectations, so a useful video answers one task specifically.
Choose the question before the keywordThe Shorts pool is the separate baseline Vidfora builds from a channel's Shorts, videos of 60 seconds or less, kept apart from its long-form videos. Because the two formats are distributed differently, pooling them would measure which surface served a video rather than how the idea performed.
Shorts and long-form audiencesA tracked channel is one you have added to a watchlist so its new uploads come to you already scored against that channel's own median. Tracking replaces rebuilding a competitor spreadsheet each week and keeps a research rhythm going between projects.
How tracked channels workViews per hour divides a video's total views by the hours since it was published. That is a lifetime average, not current speed: it flatters very new uploads and fades as a video ages. Recent velocity needs two observations over a defined interval instead.
Lifetime averages versus recent growthScoring definitions describe how Vidfora calculates its own outlier metric. They are not YouTube metrics, and none of them predicts how a video will perform.
