I have a multsite WP with subdirectories, and I know it is possible to redirect one domain to one site using WPMU Domain Mapping.
All other sites will remain as http://www.blogmultisite.com/siteX.
But I have a doubt about SEO. The blog http://www.domainX.com will be stored inside my network, but the domain will be different. How does it affect to SEO? Search engines will consider this blog belongs to my network? Or will be considered as a single blog?
Thanks a lot!
