I have 2 websites of ecommerce in France and for these websites I have a strange behaviour of the alexa results. Here are some statistics about the websites :
Unique Visits January 2012
Website A : 158,828
Website B : 58,867
Number of Search Results google
Website A : 5,100
Website B : 56,000
Links to my site
Website A : 3,120
Website B : 2,180
ALEXA Score
Website A : 405,804
Website B : 278,944
How does it come that website B with 1/3 of the visitors of website A have a much better Alexa Score ( x2 ) then website A?
