Can Someone Explain This

[mtgman]

I had a link request from this site and wanted someone with more knowledge to explain this.

He wants the linking URL to be home-mortgages-online without the www. which is a PR 4.
If you put the WWW in front its a PR 0.

Why and whats the purpose?

Not too long ago, many webmasters/owners used PageRank to decide who they would or would not exchange links with. I still come across sites that require a minimum PageRank to "Qualify" for a link exchange.

It sounds like you haven't redirected your non "WWW" to the "WWW" version. [You might consider doing this via a 301 Redirect.]

Hi,

at first I can see PR5 for homepage without www.

Domain name with and without www is not same documents on the server primarily. But usual setup of server redirects(only alias, not 301) version without www to version with www. The result is that visitor get same document when type domain name with or without www.

Guy from that server decided to link his site to version without www so it has PR5 and version with www isn't linked so that version is not even cached by G.

Regarding ResaleBrokers advice to redirect: this guy should redirect with 301 his "with www" version to "without www" version. But as I said, www is not even cached, so it is not necessary now.
