I have a blog on wordpress.com, does anyone know if I can run PPC ads there? I heard that they have some restrictions... My blog just turned 1 month old and it's getting around 1500 visits every day, so I would like to try pay per click and see if that works for me.
Why not? You just need your money for it. but seriously wordpress.com is not the best way to earn money. you might be banned soon if they recognized you make money with it.
