Need Telegram Channel ranked

So I’ve created many telegram channels over the years and usually I buy large amount of followers 80k/100k and my channel is ranked on the global search so if someone searches a specific key word then they get my channel.

However my new channel is not ranking I’m getting 0 new joins and 0 messages with 80k followers. Something is wrong. Maybe the quality of followers who can help me with this and get my channel ranked?
