Do you mean how do you raise your traffic rank from Alexa or how to get traffic from them? Alexa does have a search but its slower and crawls less so I wouldnt really look to them as a source of significant traffic. If you were refering to your traffic rank...well this is a whole other story. Alexa gathers your traffic rank from people that use its toolbar. It can be argued that the majority of people that use their toolbar also use their services...i.e. look up traffic rank. This is not your average internet user but other webmasters and developers that would need that information. Now I am not saying that ALL Alexa toolbar users are webmasters, but a very good chunk of them are. As a result, and depending on the theme of your site, you will notice that certain themed sites will have a pretty good Alexa ranks...like directories for instance. Another way to boost your Alexa rank is to purchase traffic. Alexa doesnt monitor who comes to your site or where they are referred from, but rather, the overall number of visitors based on a sample of 1,000,000. If you look at the Alexa traffic graph, some sites will have a huge spike which no activity before and none after.
yes, but it is really hard to get. Notice on the upper right corner? if you can get on the "Movers and Shakers" you will get lotz of traffic
