Alexa gives statistics on websites but I don't know how they are getting their data since I put no code on my site for Alexa - anybody know how they get their numbers?
Wrong, they have changed their algo significantly! They have a new algo which doesnt use (or only use) the toolbar to calculate the data. I think they take help from other toolbars nowadays.... Dont know which ones though... O_O
Not true any more........ As of 4-17-08, Alexa toolbar data only makes up a SMALL PORTION of the information compiled. Nobody knows exactly what the other data is comprised of (yet), but its a known fact that sites that are patronized by non-geeks (people who don't have Alexa toolbars on their browsers), are getting higher scores than before.
I never trust Alexa for anything ranked passed 10,000. I wish there were more transparency in the industry.
It is very strange but i have also observed strange facts that one of my sites without any promotion and new domain is ranking better than other one which is older, with PR and SEO techniques...I am at a fix
