Here are my estimates of the dollar values of PageRanks 0 to 9. I deliberately left out PageRank 10 because I only know of a single company that has it, and that is Google. No surprise there.

As you can see, the lower PageRanks are not of much value to an established company. Even a single-person company needs to be aiming for a PageRank of 4 or more. For us at SiteLeads.net, we are aiming to have a PageRank of 5, on April 2009. For reference, we created the SiteLeads.net website early April 2008, so at the time of writing this posting, the website has been up for about 4 weeks and we just yesterday went from "no PageRank" to "PageRank 0".

A high PageRank is ineffective if the page it refers to does not have the right keywords. The Right Keywords + Best PageRank = Success.

The relative value of a website, and the cost of increasing PageRank, increases exponentially.

A PageRank of 5 can be achieved through the diligent efforts of a single person.

A PageRank of 6 takes a small marketing team.

A PageRank of 7 can happen when the focused resources of a well-established company are applied.

A PageRank of 8 requires a large, well-established company dedicated to its web presence.

PageRanks are rounded down for display. For example, PageRank 5 is actually "five point something" -- It could be 5.12; it could be 5.98 -- reflecting a wide range of possible values.

PageRank 9 is where the truly big, high tech companies like Apple, Microsoft, IBM live.

PageRank is displayed as an integer value; a PageRank of 4 is actually "four point something". It can be 4.12 or 4.98; basically any number between 4 and 5. There is a difference between "no PageRank" and a PageRank of zero. PageRank 0 is "zero point something". "No PageRank" is zero.
