Views that do not match the subscriber count
A large subscriber base whose videos barely get views is the clearest warning sign. Real audiences watch; purchased ones do not.

Check a YouTube channel for fake subscribers. This tool looks for signs that a YouTube channel's subscriber count has been inflated. Subscribers are the easiest YouTube number to buy and the hardest to see through: a channel keeps its subscriber count on screen forever, while the views that would expose it move on after a week.
Type any public YouTube channel name and select check.

A large subscriber base whose videos barely get views is the clearest warning sign. Real audiences watch; purchased ones do not.
Sudden subscriber spikes with no video that explains them often point to bought subscribers. Steady growth off the back of published videos is healthier.
Waves of vague, emoji-only, or copy-paste comments signal bot activity rather than a community that actually watches.
A subscriber count is the first thing anyone looks at on a YouTube channel and the last thing that tells you whether a collaboration will work. Subscribers cost a few dollars per thousand from any number of services, they never disappear from the header, and unlike views they are not tied to a video that has to perform.
Paying for a channel's subscriber count instead of its audience costs you more than the sponsorship fee.
Checking takes seconds and it costs nothing. It is the cheapest step in any YouTube campaign, and it is the one most often skipped.
No single number proves a subscriber count was bought. What gives it away is the relationship between the numbers โ subscribers against views, views against comments, and growth against the channel's output. These are the four checks worth doing before you talk to anyone.
This is the check that matters most on YouTube, and it is the one bought subscribers cannot survive. Subscribers can be purchased; the views on the next upload cannot. When a channel's videos consistently reach a tiny share of its subscriber count, the count is either inflated or long dead.
Across the active YouTube channels in Heepsy's database, the typical channel's recent videos reach roughly 5% of its subscriber count between 10,000 and 100,000 subscribers, around 2% between 100,000 and a million, and closer to 1% above a million. Judge a channel against its own size:
Beware the honest version of a low ratio: an older channel that has stopped growing will show the same pattern with a completely real audience that has simply moved on. That is a reason not to pay for the subscriber count, but it is not fraud.
Comments are the most expensive engagement to fake convincingly, which is why they are the best place to look once the view count has raised a question.
Open three or four recent videos and read the top comments rather than counting them:
The reverse is the strongest positive signal you can get for free: specific comments that reference something that actually happened in the video are very hard to manufacture at scale.
Engagement rate on YouTube measures likes and comments against the audience the channel claims to have. Bought subscribers inflate the denominator and contribute nothing to the numerator, so the rate falls as the fake share rises.
Read it against channels of the same size rather than against a fixed threshold, because engagement rate falls naturally as channels grow:
Our free YouTube engagement rate calculator gives you this number for any public channel, and it pairs naturally with this check.
Real channels grow in steps that line up with something: an upload that took off, a collaboration, a mention somewhere else. Purchased growth has no such cause.
What to look for in a channel's history:
Every check above works, and every one of them takes ten minutes per channel. That is fine for a shortlist of three and impossible for the fifty channels you started with.
Doing it by hand also has limits that no amount of patience fixes:
Heepsy analyses the audience behind a channel rather than the numbers on its front page. The estimate this tool shows comes from that analysis, applied to the same database our customers use to vet creators before they spend.
What that means in practice:
The free check returns the estimated share of a channel's subscribers that our audience analysis considers inauthentic, next to the channel's subscriber count and engagement.
The full report in Heepsy goes considerably further:
Treat the free number as a screening step. It tells you which channels deserve the ten minutes of manual checks described above, and which ones you can drop from the list now.
This tool flags the signs. Heepsy gives you the complete picture: the share of genuine versus suspicious subscribers, suspicious-growth detection, and who the real audience is by age, location, and interests. Vet any channel before you spend, across a database of 20M+ creators.

Compare the views on recent videos against the subscriber count. Subscribers can be bought, but the views on the next upload cannot, so a channel with a large subscriber count and very few views per video is the classic profile. Across the active channels in Heepsy's database, a typical channel between 10,000 and 100,000 subscribers reaches around 5% of that count per video, and above a million subscribers it is closer to 1%. Then read the comments on a few recent uploads: generic praise from accounts with no avatar or uploads is the second-strongest signal.
Yes. YouTube's terms prohibit artificially inflating metrics, and the platform removes subscribers it identifies as fake โ which is why bought counts often fall back over time. Channels caught doing it risk losing monetisation or the channel itself. For a brand, the practical risk is different and more immediate: you pay for an audience that will not watch the video you sponsored.
They do, beyond the risk of enforcement. YouTube decides how widely to recommend a video partly on how the people it is first shown to respond, and subscribers who never watch are shown the video and do nothing. That weak early signal suppresses the channel's own reach, so bought subscribers make a channel perform worse than it would have without them.
It depends heavily on channel size, and it falls as channels grow. In our data the typical channel between 10,000 and 100,000 subscribers sees recent videos reach roughly 5% of its subscriber count, around 2% between 100,000 and a million, and closer to 1% above a million. Judge a channel against others of its own size rather than against a fixed number, and remember that Shorts can push views far above the subscriber count legitimately.
Yes, and it is common. An older channel that has stopped publishing, or one whose audience has moved on, will show a low view-to-subscriber ratio with an entirely real audience. The distinction matters for how you read it: fake subscribers mean the count was never real, while a dormant audience means it was real and is no longer active. Either way the subscriber count is not what you should be paying for โ but only one of them is fraud.
Yes. Checking any public YouTube channel is free and needs no account. The free check shows the estimated share of inauthentic subscribers with the channel's subscriber count and engagement.
