I've wanted to test Telegram as a traffic source for a long time, but I kept putting it off — it was unclear how much it would cost and where to start. Some said it was cheap, others said it was expensive and ineffective. When I started to figure it out on my own, I studied the issue of Telegram ads pricing . It's very clearly described: what formats there are, what budgets are needed, what affects the price. Now at least I have an understanding of how to plan tests and not waste money.
