I got the news that alexa is changing it's algorithm.. but I got shocked when I saw my site details... I don't want to say the site name but I will index them as SITE A and SITE B... My SITE A is a forum which gets around 10-20 hits from search engines and bookmarking websites daily....And it's alexa rank is 5,787,288. But my second website is webmaster related website which was just released 2 days ago after I bought domain from someone else and it had nothing in homepage.And today I got one visitors to my website from the DP sig. and when I checked it's rank it showed 1,610,513... I am truly amazed and thought that alexa change it's algorithm and it's getting confused in long digit no.s like mine..
Alexa rank is pointless and very inaccurate, you should go by traffic only, google analytics or whatnot
