We need a metric to compare our specific level of authority (and likelihood of ranking) to other websites. Google’s own metric is called PageRank, named after Google founder Larry Page. Way back in the day, you could look up the PageRank for any website. It was shown on a scale of one-to-ten right there in a Google toolbar that many of us added to our browsers.
Yes solid keyword data dramatically changes the game as far as rankings go. I have seen many tools that provide Cost per click stats and meaningless charts that confuse most users. the data Jaaxy provides helps drive “organic” traffic to your site on a consistent basis which will out perform PPC sites every time. I like how you say thinking like the end user, as I feel that way when I search. I dive into what people are looking for and it really helps drive content idea’s. I have seen great results from that.
