I have a domain that I have set up several health niche sub domains on. Does this hurt or help the domain and is there any special way to promote the sub domains other that the normal fresh content and SEO? I actually set up the subs first and have just now started working on the domain itself. The sites all have the same Alexa rank of 2,354,546 and no page rank. I posted the first article to the main site yesterday and will add more today. Does anyone have any suggestions on how to promote the "network" to get the most bang for my buck or time. I am hesitant to list the domain because I am new to the forum and I do not want to break any rules. Thanks for any help. Ferrellmac
your subdomains need backlinks as much as your main domain does (or even more) alexa does not track subdomains separately from the main domain
