I've been using Traffic Travis for a little while, in part because I can get by with the free version. One thing that's always baffled me though is how it decides whether a KW is hard or easy to rank for. I take a look at the report for a keyword that is easy vs. medium, and sometimes it doesn't look like there's much difference. In some cases, the one with medium difficulty seems to have pages with less authority, fewer backlinks, and less optimization. Is there more that Traffic Travis is doing behind the scenes? Am I looking at the wrong stats? Or should I just trust my gut?
