subdomain and se
Does search engines treat subdomain as a completely different site? For example, www.keyword1-keyword2.xyz.com is a different site from www.xyz.com?
BTW, for www.keyword1-keyword2.xyz.com, they will understand keyword1 and keyword2 as key words, is this right?
Yes, it will see those keywords.
And search engines usually dont' care if they're on a different site from before or not.
