Hello experts, I have 4 sites, each of them is under a subdoamin My main domain is forwarded to one of these sudomain as there is no page at www.mydomain.com Now, When Building links which is better for SEO and PR ? Build links to www.mydomain.com Only ! OR Build links to each subdomain individually ! Thank you
You really need to get rid of the sub-domains and just use a regular domain for each site. You'll want to build links to every page of your site. Most people make the mistake of just back linking their Homepage/Main URL. Diversify your Keywords in the Anchor text also.
