I am interested to get peoples opinion on the pros and cons of the effect of a subdomain and normal directory extension in relation to search engine optimisation? if any difference at all?
By subdomain, I mean "test.domain.com" and directory extension being "domain.com/test"
Are their any benefits in using either method to improve the overall search engine optimisation process?
By subdomain, I mean "test.domain.com" and directory extension being "domain.com/test".
My understanding is that a sub-domain will outperform a sub-directory based on certain circumstances. For one, do you have enough unique content to start breaking out the site into sub-domains? If not, then it may not be worth the effort.
But, if you do have a medium to large site, a sub-domain structure may be a viable solution for both usability and indexing purposes. Remember, a sub-domain is one level above the root. A sub-directory is one level below the root. Sub-domains are treated as separate entities as evidenced by the indexing of www. and non-www.
I also remember reading somewhere that because of how spammers have taken advantage of subdomains in the past that their usefullness has been deprecated with search engines.
Any comments?
