Hi, I have to admit I have been asleep at the wheel. I have a page on my site with PR 6 but I only place 5th in the search results for a certain 2 word search phrase. 4 other sites have pages with PR 5 but they place in the top 4 slots. How can that be? I used to think PR was the definitive measure for result placement. Thanks for your feedback.
Keep in mind that PR depends only on linking structure. It has nothing to do with page content or the keywords being searched for. That's why the Google Toolbar can show you a page's PR when you're simply visiting it.
Look at it this way: Apple Computer's home page has a PR10, but you wouldn't expect it to turn up in a search for "fresh oranges", would you?
Never thought I would say this, but forget about it. The PR of your site, although important, and more is always better than less, just doesn’t have a whole lot to do with where you rank anymore. It's a result, not a cause.
