It feels good to be in a good Alexa rank. I want to make one of my websites in the top 10k websites in the worldThe more number of hits you get from different ip's, the more your alexa rank you get. It doesn't matter if it's dedicated or dynamic ip. If the user is visiting your site again and again from the same dedicated IP, it won't improve your alexa rank. Why bother about Alexa in 2014?
