I tried AdWords and ran out of $50 fast, and losing $40...... I also tried a couple other ppc engines and for me the best one is 7Search, I can get tons of related bids for 1 cent each, what other engine drives traffic for 1 cent for all clicks. With the other ppc engines, it eats your money right up, because it takes a lot of clicks to convert, and if your selling a cheap product or relying totaly on making a profit from clicks on your ypn or AdSense ads, then your PPC bids better be around a penny each, or you will soon be throwing ppc money away. Espicaly when AdSense oftens pays a cent or two per click now.
i mean, in adwords if a give money, then most probably my ads will displayed in some blogs etc....... 1-5 cents a click, possible on quality websites and not blogs...........
Avoid Brainfox.com...it's a SCAM..7search was nothing special...Google, Yahoo and MSN are all you need
