Content delivered from a sub domain,the website watercolor painting.com is running on WordPress.The website is loading from a sub domain where WordPress is actually installed.Is that a problem?
JOHN MEULLER (Webmaster Analyst from Google):
No. In general, that’s absolutely not a problem because we probably don’t even see that when we crawl the website. We see your main domain. We don’t actually see where physically that content is coming from. We just see that this content is being served through your preferred URLs, and that’s what we’ll focus on. The one thing to kind of watch out for there is sometimes you might find a link to your staging site or the original source server where this content is currently hosted. And if you don’t take any measures to prevent crawling or indexing of that content there, then maybe we’ll index that version as well. And in an extreme case, maybe we’ll say, oh, this is probably the original version, and start showing that in search instead of your preferred version. So that’s something to watch out for. On the one hand, maybe you can block crawling and indexing of that staging site or that original content source. Alternately, what you could also do is– or not alternately, or maybe additionally– you could make sure that you’re using rel=canonical on these pages so that we really know that this is actually the URL that you do want to have it indexed.
