Google’s famed page rank is both well known and unknown. Everyone knows that a higher page rank is “good” because it means the Google robots think your page is “important”. On a 1-10 scale, the higher the better.
You can get the Google Toolbar which shows you Page Rank and start obsessing today!
Looking for sites that rank at the very top starts with Google – not surprisingly, but right on their heels is Adobe. Adobe is linked to by millions of pages for their products, this certainly helps their entire site.
Adobe Reader has a PR of 9, other Adobe pages rank 10. Certainly we have all seen the links to Adobe’s PDF reader, all those links tell Google, “Adobe is important and trusted”.
I think you can see that all of those sites are seen as “important and trusted”.
If you could get lots of links from some of sites like those listed, you would certainly see an increase in your site’s page rank.
The downside of constantly checking your site’s page rank is that there is really no way to do it. Google only “releases” page rank a few times a year, often unannounced. And when they do, the data is already “old”, usually at least a couple of months.
So while “real page rank” may still be an important part of how Google views your site, only the internal Google engineers know what it really is. The simple Google Toolbar number they display is just a rough estimate for you.
