I found nice website, where is explained, how to Increase website Alexa Rank. Website name is Dosh Dosh, and here is some part of tips:

1. Encourage others to use the Alexa toolbar. This includes friends, fellow webmasters as well as site visitors/blog readers. Be sure to link to Alexa’s full explanation of their toolbar and tracking system so your readers know what installing the toolbar or extension entails.
2. Work in an Office or own a company? Get the Alexa toolbar or SS Firefox extension installed on all computers and set your website as the homepage for all browsers. Perhaps it will be useful to note that this may work only when dynamic or different IPs are used.
3. Get friends to review and rate your Alexa website profile. Not entirely sure of its impact on rankings but it might help in some way.
