Should We Use Subdomains for SEO?
For better search engine rankings, we need to adopt different policies which can help us to get our sites listed on the SERP (search engine result pages).
SEO Theory contributor Michael Martinez has published an article highlighting the pros and cons of using subdomains for SEO.
He says, “Subdomains are older than the World Wide Web. RFC 1034, adopted in November 1987, defined subdomains this way: “A domain is a subdomain of another domain if it is contained within that domain.” Seems simple enough. And yet generations of Internet pontification have disagreed on whether “www.[whatever]” is a subdomain or something else.
To a search engine there is a URL – a Uniform Resource Locator as defined in RFC 1738 (adopted in December 1994): “A URL contains the name of the scheme being used () followed by a colon and then a string (the ) whose interpretation depends on the scheme.”
We’ve learned to think of URLs as addresses. You type a URL into the Web browser address bar. You bookmark a Web address. You might trace a path to a Website by its IP address. If you put a in front of a domain name or an IP address you have a URL. So it’s not quite what the colloquial uses make it out to be”.
