Quote:Suggestion #1 - Take a look at Gary's PPC marketing and Long Tail Analysis. Here you will learn how to implement Long Tail analysis on your website for the purpose of tracking keywords nobody else has. Long Tail analysis is offered for free by Hitwise.com and essentially gives you a real time result of all keywords people use to reach your web site. You get all the obscure keywords that may not have very many searches, however, multiply that by 10 000 and you have a good keyword set.
