I am trying to do something in keyword researching.For that i have read many articles about this.Have gathered many things on this but still now having some confusion about saying a keyword is low competition.However i have understood so far........... a low competition keyword must have 1. Under 10k intitle:"keyword" real competitor 2.Average PR under 3 of the first 10 sites 3.No presence 2/3 official big site on the first page like wikipedia, wiki 4.No presence of original product page on the first 2/3 position. 5.Backlink of each different sites of the first 10 need to be under 1k 6.No presence of google shopping result on the front position( still i am confusion about this) Am I correct(i have told i m still new here)? If No please share your idea as we can learn from you. OR if you know any more criteria to select a keyword as low competitor please share that with us here.We who will learn something form you will be grateful to you.
