How is PageRank determined?
The Google theory goes that if Page A links to Page B, then Page A is saying that Page B is an important page. PageRank also factors in the importance of the links pointing to a page. If a page has important links pointing to it, then its links to other pages also become important. The actual text of the link is irrelevant when discussing PageRank.

How can you tell what a page’s PageRank is?
To learn what a page’s PageRank is, you can download a toolbar for Internet Explorer from http://toolbar.google.com. Once installed, there will be a bar graph at the top of the browser showing a version of PageRank for the page you’re browsing. When you hold the mouse over the bar, you see a number from zero to ten. (If you don’t see the number, you may have an older version of the toolbar installed. You will need to completely uninstall it, reboot your computer and reinstall the latest version. Once this is done, you should be able to see the PageRank number.)

How accurate is the Google toolbar?
The Google toolbar is not very accurate in showing you the actual PageRank of a site, but it’s the only thing right now that can give you any idea. As long as you know the toolbar’s limitations, then at least you know what you are viewing. There are two limitations to the Google toolbar: 1. The toolbar sometimes guesses. If you enter a page, which is not in its index, but where there is a page that is very close to it in Google’s index, then it will provide a guesstimate of the PageRank. This

guesstimate is worthless for our purposes because it isn’t featured in any of the PageRank calculations. The only way to tell if the toolbar is a guesstimate is to type the URL into the Google search box and see if the page shows up in the SERPS. If it doesn’t, then the toolbar is guessing!
