One reason is that you received low-quality subscribers from Telegram ads.
- This is when less than 10-30% of subscribers read your channel
OR/AND
- Engagement is very low
OR/AND
- You got subscribers from very poor regions of the world.
You might feel good about the number and brag to your friends, but knowledgeable people and advertisers won't be impressed. For them, it will be like you just bought bots. So, after reaching a large number, you will be disappointed because you won't be able to monetize such a channel.
You need to thoroughly check the channel before advertising on it. Here are a few points:
1. Make sure the channel's theme and audience match your goals and your channel's theme. First, advertise on Telegram channels with similar themes.
2. Use services like TG Stat or others to:
- Get detailed channel analytics, including the number of subscribers, engagement level, post reach, and growth dynamics.
- Check how the channel's audience was attracted.
2. Visit the channel and study it:
- Look at the comments and discussions, if any. This will help you understand the channel's audience better.
- Evaluate the quality of posts: how informative, relevant, and interesting they are.
3. Watch your subscribers from the ads:
- Look at the comments.
- See who subscribes.
If you suspect low-quality traffic, immediately stop advertising on ineffective channels.
Also, even after checking everything, there can still be many unpredictable factors that affect the quality of subscribers.
Once again: the number of subscribers doesn't matter; what matters is the quality of these subscribers. You can't monetize a channel with a low-quality audience.
