Can someone explain this Alexa Report?

[EWpro]

Hi,
Can someone explain me about the Alexa report?
We are working on a new site for few weeks by now. For which
1. The Alexa report says
Three month Ave: 2,733,139
Last Week ----: 1,027,777
Today: 256,581

Q: Is '256,581' is the todays rank standing for the site or something else?

2.
Where do people go on xxxxxxx.com?

* aaaaaa.xxxxxxx.com - 36%
* bbbbbbbbb.xxxxxxx.com - 36%
* ccccccc.xxxxxxx.com - 14%
* ddddddddd.xxxxxxx.com - 14%

Q: Above it shows only four of the existing subdomains. Whereas some other sub domains attract more visitors than the listed one. Why they are missing?

Thanks in advance for your expert advice and valuable time.

[PS: Mod excuse if it is a wrong section for this!]

EWpro,

Don't get too wound up about Alexa stats. They are pretty but they don't mean a lot and are easy to manipulate. If you want to soar through Alexa's rankings get 10 friends to set your homepage as the initial page when they open their browser. Then once you've broken the 100,000 tell them all to take your homepage off and you'll see what I mean.
