How can i get more users ?

Try advertising make really good updates etc and the players might come if you gonna be nice to them etc they will come back 100% just try to make good updates etc

use adsense or other plataforms for ads! and you have users.

have an active staff team that like to engage with new players. also making sure there's a lot of ways to make money is a good idea lol

Just try and advertise ur server on alot of discord servers and etc

Get a good server, the users will come to you! Trust me on this it always works

You definitely need something that other servers don't do. Or, find stuff that works on a couple other servers, and keep out the garbage that doesn't!

I agree with the above suggestions
Get a new server and see users flooding you

try to stream or make youtube videos, so players can see your server

I got more users to my server by promoting it on the official Garry's Mod Discord server. Here's the link [disallowed website]

As a previous server owner and developer, I recommend a few things.

Firstly, there are hundreds of other servers around who use default plugins/addons so I recommend investing in a developer to make you new content to make your server unique.

Secondly, make friends in other servers under the same game mode so they can come and try out your server. That should boost your player count to ten or maybe twenty.

Thirdly, have a good staff team to moderate the server even while you are not around. It makes the server more enjoyable to those who care.

Fourthly, do NOT advertise on other servers as people will begin to dislike you.

If you get enough of a player base, people will begin to try your server, and that custom content and genuine "community" vibe will keep you going. If you have a bad server with bad content, people will not stay because there are better servers around.

But in all reality, it is purely chance. You may be competing with an absolute titan of a server so it might be hard to compete or maybe that titan server shutdown and you have tonnes of isolated players looking for a new server. Really luck of the draw most of the time.
