Firstly this is quite complex (to me anyway), but I'll try to explain it best I can;
I have a website (WEBSITE-A) which is hosted by siteground. All working nicely for 2 years. My package with siteground includes unlimited storage space, which is great.
I've recently bought a domain name using www.123reg.co.uk, its a .co.uk name. This is a small website I'm setting up, WEBSITE-B.
Since I already have unlimited space with Siteground, I decided to create a subfolder on WEBSITE-A called WEBSITE-B, and uploaded my phpfiles. Now when I go to www.Website-A.co.uk/websiteB my new website appears, great. I then logged into 123reg.co.uk and told it to forward all requests for www.WEBSITE-B.co.uk to www.Website-A.co.uk/websiteB. So now, when I goto WEBSITE-B.co.uk it appears correctly.
However, I've just found out that using this method of forwarded is frowned upon by search engines, and that I can fix it by altering the DNS settings of WEBSITE-B via 123.reg.co.uk
My questions is, what exactly should I change, and will I need to buy a new hosting package or can I continue to keep wesite-b as a sub-folder of website-a?
I hope someone out there can understand this, and explain how I should be setting things up.
Thanks guys.
