I purchased 2 domains (domainA.com & domainB.com) through Namecheap and will be hosting them on Hostgator, because it allows me to host unlimited domains. When I was going through the Hostgator ordering process, it asked me for my (main) domain name. I used domainA.com. I have added domainB.com as an addon domain but have noticed that it adds it as a subdomain. I can still access it as http://domainB.com but it shows up as a subdirectory in my FTP program. My question is, does this affect SEO in any way? Having it show up as a "subdomain" even though I can still access it directly (http://domainB.com). I guess I can always pay the $5 to have domainB.com be my "main" domain, but I just thought I'd check here first before doing any of that. I already contacted Hostgator but they could not help with my SEO question. They just said that my addon domain is also considered a subdomain. Please let me know if anyone needs any clarification...it's late Thank you.
