People have being looking for a toolbar for Chrome browser to display the famous Google PageRank bar of the web page currently visited web page.
Well there isn’t one, unless somebody can tell me otherwise.

Thanks to the open-source community, you can instead use  a browser extension published by “kalehrish”. Here is a link to that PageRank Extension for Google Chrome. I just downloaded and installed it. As far as I know, it integrates well with Google Chrome 4.0.249.78 (36714) for PC.  I did not get a chance to check how it would behave on a Mac.
It works like a charm for me and it’s very lightweight.

A while back, Google  removed PageRank from the Webmaster Tools section of its website. The big G also informed us that little green bar is not as important as we might think. Indeed the PageRank is not all there to SEO but that green bar is an indicator of the quantity & quality of inbound links to a given web page.

We know that search engines put more emphasis on relevance of the page content to the search query for ranking. But all things being equal, the higher the Pagerank, the better the page placement in search engines results.

Another option is the Kuber PageRank Checker. It not only display the Pagerank  beside the address box but it also show the Alexa rank and a whois link when clicked: talk about killing three birds with one stone.
