Needing tips for an open mic

Hey all! So, I’ve been in standup for a little over three years now and am doing alright for myself at the level I’m at. I just started my own open mic and am wondering what I can do to help it to succeed. The bar is in a great area, unfortunately it just isn’t popping off. I have some ideas for what could help bring in comics (giving out $1 scratch offs for the first ten sign ups was one), but I want to know what else I could do to entice both comics and patrons.
