From one nOOb to another...
I haven't been around here long but I lurked long enough to know that this type of question will not get you anywhere with this crowd. Lazy people are not rewarded on this site. Put in some effort and look beyond one thread and you will find golden information on this subject. I mean that in the most helpful way possible...
To get you started Arbitrage or arbi, by a general definition is taking advantage of market imbalances in order to realize a profit. More generally it can be summarized as "buy low and sell high". In this realm it means driving cheap traffic to a page that results in higher returns. How you do this is up to you and with some determination you will find ways that many very successful and brilliant people on this board have done (and continue to do).
Don't look for a handout here, do your homework (even beyond the scope of WickedFire) and you will find that the people here don't suffer fools, but they are damn sure generous with some ridiculously good info. I don't mean to be dickish, but thems the breaks!
