"It is worth stating that using the AdWord Keyword Tool to help you choose keywords for your blog will have different impacts upon different blogs - depending upon how well they already rank on Google," Rowse says. "If your blog is new you might not notice much difference in the traffic no matter what keywords you use (simply because your blog is yet to build a ranking in Google yet) - however in time, as your blog accumulates links from other blogs and sites, it will certainly pay off."
