I’ve heard alot of hype about Alexa ratings and also Google PR.

Google PR is quite international based, as it is calculated with inbound and outbound links etc.etc.
Google PR is not the amount of traffic but you Page Rank with google. Paul from blogmad gave me quite an extensive quick tutorial over MSN a few weeks back.

Alexa again is more US based(people that have an Alexa bar loaded in their browser), as it is based on real traffic, I went through their FAQ and it looks like is is a calculation about the number of unique visitors and amount of pages etc. …

I went and checked the domain I handle to see where they rate one Alexa and Google.
