I am planning to start a promo campaign to gain more visitors to my site (currently about 50.000 visitors a month) and if possible more members for my paid membership section (nothing adult, just martial arts ;-)
I was wondering which was the best buy :
- keyword ad on Yahoo
- a text links with Sprinks (about.com)
- a positioning with Goto.com
- Ad campaign with banners like "bPath" (formerly hyperbanner.com)
- buying ad space in printed related Mag

Any help welcomed.
