Look guys. I know my thread has caused some confusion among some parked.com customers. Even though arbitrage might work for some people, it doesn't mean it suits you if you don't have that area of expertise. If you are lucky and do it right, you might be earning big bucks in the short term. If not, it will eat up a lot of initial capital. So that's always the risk there.
Let me quickly reiterate that, there are always pros and cons with the two approaches: arbitrage and natural traffic.
Arbitrage -
Pros:
Higher ROI in the short term if it's successful
You can sit and watch the revenue grow if you are lucky enough to identify a profitable campaign
Cons:
Time Consuming
Higher Risk
Very High Investment
SEO
Pros:
Lower Risk
More Stability
Cons:
Lower ROI
Requires consistent time and effort for SEO
You need a big portfolio to earn big dollars
I hope this information helps clear your mind.
