I'm open for ideas and this is the only forum I'm posting this stuff in. A lot of you guys are crazy, but I know many of you know your shit and I like crazy. I'm a fight promoter!
What can we do?
You know what you should do? You should start becoming friends with all the other MMA sites out there. Share content with each other. Share fans and users. Share whatever you can.
Since you're coming to us, I would say "just pay for some dumb banner ads on other MMA sites. (just remember to sell the click)". I'm sure some of the admins of those sites never expected to make any money off it, so offer them something they can't refuse (like your wifes tittays for a blog post featuring your site).
Use Google Adwords, Yahoo, and Bing. It may be hard to measure ROI, BUT you can always set a daily budget (of $1 if you need to). If you wanna grow the site cheaper and quicker, you should do what I mentioned earlier.
Good Luck Bro.
