I'm not sure if this information is something I should pay for (maybe it's an industry secret? or something in a WSO?) so just direct me to one if that's the case.
I'm using Market Samurai (trial) and I'm done looking at 5 keywords and their ranking competition. Being new to IM, I'd like to start with low competition first and gradually penetrate the high competition keywords. This is for the Amazon affiliate site I'm starting.
Let's say I enter this keyword and MS comes up with sites with low PR for its top results. Does that already mean that it's low competition? On the other hand, I have this keyword that has high PR sites as competition but the on-page SEO is mostly "N's"/ green. Do you think I should look at Backlinks stats instead?
