To get more people on the server this is what I did.
1.Find a popular website
2.Find a way to advertise on the website
2a.Talk to the owners to just do it as a favor.Advertise space.Or posting(if you can)
3.Make sure you include a link and if you can add a description of our server
If people go on the website alot its sure to catch a eye!
I'm doing it some popular websites I know already!
