Sorry guys but I strongly disagree with you. Most people fail when they start advertising with PPC. Not because it's hard, but because they probably jump without testing the water first. When I started with PPC, I started making good money from the very first weeks. But I worked a lot on it. I read books, ebooks, courses, participated in forums such as DP, and did a lot of testing on my campaigns. I am not saying PPC is gonna be easy from the beginning. But if you do the right things, $150 a month is not even gonna be pocket money. It might quickly become your minimum daily target.
well... as i said before.. ppc could be hella hard... as i've wasted like $150 bucks on adwords. i almost cried. i suggest you to do some bh methods... and invest that money on whitehat projects... that's what im doing..
