Multisite Subdomain want like subdomain wordpress.com

sorry in advance if my bad english, because it is not my main language

I’ve made a WordPress multisite until worked, who want to ask how to order each subdomain has alexa rank + google page (blog.com or wordpress.com) becomes zero and so does not follow the main domain .. because I was looking at these forums and google does not know who should be in the search keywords …

thanks
