The money will go away, but the CTR will be at 0.1%.
Instead of a live audience, there are bots and fake views.
The ad won't fit into the content and will cause rejection and a wave of hate.
The problem is that it's impossible to visually distinguish a "dead" community from a living one. This is why a systematic check of Telegram channels for fraud is necessary before launch.
How to Check a Telegram Channel: Key Metrics
Engagement Rate (ER) is the engagement rate of morocco telemarketing database subscribers. It reflects audience activity and is calculated as the ratio of interactions (reactions, comments, reposts) to the total number of subscribers. If the ER falls below a minimum threshold, this indicates low subscriber engagement.
Post views. This metric serves as a primary indicator of actual reach. A good channel attracts views of 20% or more of its subscriber base. If all posts have the same number of views, this is likely the result of bots or manipulation, which should also raise concerns.
Subscriber growth. It's important that subscriber growth is steady, without any sudden spikes. The graph should resemble a "ladder," not a "sawtooth." If a channel gains, for example, 5,000 followers one day and then loses 3,000 the next, this is cause for concern.
Advertising frequency. Channels overloaded with advertising lose audience trust. The optimal frequency is one advertising post for every 5-10 regular posts. Any more than that and the community becomes a bulletin board and raises suspicion.
If you want to properly evaluate your Telegram channel, start with these basic metrics. They will help you get an objective picture of your audience's activity.

How to identify fakes and scams
The biggest threat is fake subscribers and views. They eat up your budget without providing anything in return.
Here are the signs by which you can identify a fake channel.
A sudden increase in audience without advertising or a viral post.
Non-unique content, copied from one source to another.
Subscribers don't like or comment (low ER).
The comments are monotonous, meaningless, or in incomprehensible languages.
Most mentions are in channels with 10-20 members.
That's why it's important to understand how to check for fake subscribers on a Telegram channel in advance —this will allow you to weed out fakes even before the first post.
