How to check a Telegram channel before buying ads

Views matter more than subscribers

An advertiser pays for how many people see the post. So the first number is average views per post over recent weeks, not the subscriber count. Fresh posts are still gaining views, so the tool on this page only counts posts older than a day.

What ERR tells you

ERR = average views ÷ subscribers × 100%. There is no single norm: it depends on the niche and channel size, so compare the channel with similar channels in your niche. If there are many subscribers but ERR is clearly lower than its neighbours’, part of the audience may be fake or long gone.

Signs of fake subscribers and views

• Views are almost the same on every post, whatever the topic or time.
• The average is far above the median: reach rests on a few posts, while a typical post gets much less.
• Lots of subscribers but almost no reactions or comments.
• Sudden subscriber jumps with no ads or mentions.
• A huge audience with rare posts.

What else to check

• Topic and audience language — do they match your product.
• How many ads already run: with an ad every day, attention to each post gets diluted.
• How often posts go out and how long the channel has existed.
• After the placement — your post’s views a day later.

Numbers a screenshot can’t fake

There is no way to verify an admin’s screenshot. In the TGStudio catalog the platform counts a connected channel’s numbers itself: subscribers through the admin bot, views and ERR through the owner’s userbot account.
