I agree google analytics ROCKS!!

How is alexa be better than google anaytics ?

Google is far more accurate than alexa , i think its googles best webmaster product

Ask traffic report from the seller.

Google Analytics is the best ever!

Data from Alexa are not accurate and not updated often.

Assuming that you do not have access to google analytics - you can simply ask seller to sent you a report from it. This way is simpliest and more accurate.

Other service like alexa can give you only a faint idea about a traffic.
