As a professional Lookup Engine Optimizer, I am questioned a good deal of queries by men and women who will not know the first matter about computer systems enable alone lookup engines. I am also questioned queries of individuals fortunate number of who are new to the subject, and amongst these so-known as “rookies” a recurring issue generally pops up – Which of the subsequent means is ideal to construction internet site URLs?

  • www.internet OR
  • subdomain.internet

In this report I will try to respond to the issue, “which URL construction is ideal in conditions of SEO, subfolders or subdomains?”

Limited Reply: If the breadth of an situation or keyphrase will be included in these depth that a new website really should be made to ideal accommodate the content, or far more just, if the site’s graphical navigation will need to be altered, use subdomains. In all other situations, use subfolders.

Prolonged Reply: To respond to this issue in depth, we’ll need to go in excess of a number of important specifics about subdomains, subfolders and internet site themes.


  • Represented in the URL by the people immediately after “http://” and the kinds before “.internet”
  • Are seen by Lookup Engines as totally special websites impartial of the dad or mum area.
  • Internet site Authority (in other terms, the skill for the internet site and its subsequent pages to rank in the lookup engines) is not passed down from the dad or mum area.
  • Can be shown on the first web site of the SERPs alongside with primary area pages. Feasibly, all ten of the effects on the first web site of a lookup engine could be subdomains of a single dad or mum area.


  • Represented in the URL by the people immediately after “.internet” and before “filename.html”.
  • Are seen by Lookup Engines as a subdirectory inside a internet site.
  • Internet site Authority is passed down from the primary area.
  • At most, a person subfolder can show up on the first SERP from the same area or subdomain.

Internet site Concept:

  • As a general rule, the far more centered the concept of a internet site the much easier it is for that internet site to rank for search phrases directly linked to its concept.
  • Is described using all of the site’s pages, not just the homepage or major subpages.

So here is the extensive respond to:

Lookup engine optimization is all about driving the most traffic. The place the objective is to create an authority internet site with lots of excellent content that will be uncovered by lookup engine pushed site visitors using laser-focus on lookup conditions, as very well as special, “extensive-tail” lookup conditions that most would hardly ever feel to optimize for, but show up on pages in the subfolders of your internet site and push traffic just the same.

Working with subdomains may possibly show up sexy simply because they can guide to a perhaps much larger selection of back again-hyperlinks (nevertheless not if each individual subdomain is hosted on the same IP), or they can sway the SERPs in your favor by crowding out the major positions with your pages. But without correct marketing, a subdomain only stops probable laser-focused as very well as “extensive-tail” lookup site visitors from getting your internet site.

My tips is only to use subdomains when the sum of content on a provided topic is so burgeoning that it demands a different navigation and design and style (i.e. its own website), or is of excellent enough quality that it will purchase hyperlinks and stand on its own.

For illustration:

  • If you have a 15 web site internet site about your garden-treatment company, and ten of individuals pages revolve close to a exclusive fertilizer you’ve made, you may possibly contemplate creating “specialfertilizer.internet” so that you can marketplace your fertilizer independently.
  • Just take my firm’s area “”. A short while ago, we created a subdomain “”, simply because we had so significantly details about our wireless software improvement solutions that it only built perception to develop a different internet site for it.

In this illustration, the target is slim but there is however an extensive sum of content. So we’re sending site visitors to the subdomain using focused search phrases whilst site visitors are also getting us using “extensive-tail” lookups and landing on the pages of subfolders.

The overall lesson here is to develop subdomains ONLY when you have the quality and/or quantity of content to support them. Don’t forget that subdomains are impartial websites in the eyes of the lookup engines, meaning that in order for them to rank, they will require marketing and connection setting up attempts.
