The best ppc i found is http://wordeva.com its new and will put you at the top of searches for .01 with $20 sign on bonus to get your advertising started. Awesome affiliate program / publisher program top paying. Goto: http://wordeva.com and check it out for your self. This one is just like the big dogs when they first started. I believe http://wordeva.com will be at the top of pay per click websites generating unlimited amount of traffic for its advertisers. I would suggest to get in early before you end up paying more per click.
PTC are the silliest way to make money. Don't waste your time with those. I'd rather write a 500 words article than click on some useless adds and get bored after a month or so.
