I am looking to start IM using amazon affiliate. As a first step I was looking to do some keyword analysis. I did some using Google adword tool. Then tried a trial software PowerSuite however the moment I used my IP kind of got flagged by Google and now have to enter captcha for even a google search. Few Questions (I am very new so looking to keep Budget bare minimum.) 1) Should I be using proxy before using any seo tool. 2) If so, are public proxies good enough or should I be looking towards VPS. 3) Some tools I see automatically uses proxy for querying other sites. Any suggestion for such free or trial software (Better if its little cheaper to buy later. I looked at SEOMoz that has trial but too costly for me, Keyword Squire doesn't have any trial version). I am looking to find keyword suggestions and for each keyword search vol, cpc and competition.
