What is the difference between real Page Rank and the Page Rank green bar shown in Google Toolbar and what are other online and offline Page Rank tools?
@raveenasenJun 27.2013 — #PageRank, also known as link juice, is a metric of the weight of a page's back links or inbound linkage.
Tool Bar Page Rank reflects what a page's PR was at a certain unknown point within the past 90 days or so - rounded to an integer. It's value is vague and often irrelevant. It varies across data centers. It's far from "real time". Pages that are dripping wet with PR can display low TBPR values, or a value of 0 - until Google decides to update the green bar. Focusing too much on the TBPR is a bad habit.

Well, there is no difference in toolbar page rank or rank of a web page.
@rtretheweyJun 28.2013 — #Google maintains an internal database of PageRank values that is continuously updated as they crawl the web. If you want to call something "real PageRank", it would have to be this database. Periodically (typically every three months), Google exports this data to another database that the Toolbar uses to display PageRank values. This process can take a day or so to propagate to the various datacenters around the world. This is the only publically-available PageRank data, and every independent PageRank tool relies on this same data. The data is reasonably up-to-date at the time of the update, which is demonstrated by the fact that (with rare exceptions) new websites receive a PageRank score on the first update following their creation - even if it's shown as "0".
