My server is a Kitpvp server, everything is made and i just need people. I posted it on planet minecraft but no one is joining and i don't want to go on big servers advertising it. can someone give me some advice?

What do you mean by update? what should I update?

You can check this post, there is a section on methods to advertise your server.

Patience is going to be your biggest factor.

or money.

If you have a good idea for a server and you treat your players well, it will grow if not by just word of mouth.

Or you can throw money at advertising and get your name everywhere whether you do well or not.

As someone said, a banner does help. MSG me if you want a gif banner, I'm fairly good at them and they are fun to make.
