    Hello everyone,

    I operate a website called Icy Veins (www.icy-veins.com), which gives gaming advice for World of Warcraft and Hearthstone, two titles from Blizzard Entertainment. Up until recently, we had articles for both games on the main subdomain (www.icy-veins.com), without a directory structure. The articles for World of Warcraft ended in -wow and those for Hearthstone ended in -hearthstone and that was it.

    We are planning to cover more games from Blizzard entertainment soon, so we hired a SEO consultant to figure out whether we should use directories (www.icy-veins.com/wow/, www.icy-veins.com/hearthstone/, etc.) or subdomains (www.icy-veins.com, wow.icy-veins.com, hearthstone.icy-veins.com). For a number of reason, the consultant was adamant that subdomains was the way to go.

    So, I implemented subdomains and I have 301-redirects from all the old URLs to the new ones, and after 2 weeks, the amount of search traffic we get has been slowly decreasing, as the new URLs were getting index. Now, we are getting about 20%-25% less search traffic. For example, the week before the subdomains went live we received 900,000 visits from search engines (11-17 May). This week, we only received 700,000 visits.

    All our new URLs are indexed, but they rank slightly lower than the old URLs used to, so I was wondering if this was something that was to be expected and that will improve in time or if I should just go for subdomains.

    Thank you in advance.

      Hi Damien,

      So if I'm reading this correctly, the consultant is saying that due to the size of the site (tens of thousands of pages), and the need to categorise its content, that subdomains are the best choice.

      I would say that there are far bigger websites using categories within subfolders, notably big retailers, e.g.

      http://www.marksandspencer.com/c/beauty, http://www.marksandspencer.com/c/food-and-wine, http://www.marksandspencer.com/c/mands-bank

      http://www.waitrose.com/home/inspiration.html, http://www.waitrose.com/home/wine.html, http://www.waitrose.com/content/waitrose/en/home/tv/highlights.html (<-- the last one being a crappy version, but a subdomain nonetheless)

      and so do websites that deal with providing content for very different audiences:

      http://www.ncaa.com/schools/tampa, http://www.ncaa.com/championships/lacrosse-men/d1/tickets, http://www.ncaa.com/news/swimming-men/article/2014-03-29/golden-bears-and-coach-david-durden-earn-third-national-title, http://www.ncaa.com/stats/football/fbs

      Has the consultant provided examples of other websites doing this that would take on the same structure?

      There are hundreds of examples of websites whose structure / categories are properly understood despite existing in subdirectories, so I'm still sceptical that this is a necessity.

      This is not to say that a subdomain approach wouldn't work and is definitively bad or anything, I'm just not really convinced that the reasoning is strong enough to move content away from the root domain.

      I disagree about user experience - from a user's perspective, the only difference between subfolders and subdomains is the URL they can see in the address bar. The rest is aesthetic. You can do or not do everything you'd do with the design of a website using subdirectories that you'd do with a website(s) employing subdomains. For example, just because content sits on www.icy-veins.com/wow/, its navigation wouldn't have to link to www.icy-veins.com/hearthstone/ or mention the other brand in any way if you don't want to. You can still have separate conversion funnels, newsletter sign-ups, advertising pages, etc.

        Thank you for shedding more light on the matter. Here are the reasons why our consultant thought that subdomains would be better:

        In the case of ICY VEINS the matter is clear, subdomains will be the best of course of action and I will quickly explain why

        -          The domain has over 10,000+ pages (my scan is still running looking at 66,000+ addresses already) which put it in a whole new category.  For smaller sites and even local business sites sub directories will always be the better choice

        -          Sub Domains will allow you to categorize the different categories of your website.  The sub domains in mind are all relating to the gaming industry so it still makes it relevant to the global theme of the website.

        -          Splitting up the different categories into subdomains will allow search engine to better differentiate the areas of your website (see attached image named icy-veins SERP – Sitelink.png).  At the moment Google do not properly categorize your areas of your website and uses your most popular visited areas as the given site links in the search engine results page)

        -          However noting that you already have the sub directory /heartstone  a .htaccess 301 redirect for that whole directory will have to be set in place for any current.  This will ensure that any inbound links from other sites will be automatically redirected to the correct sub domain and index page.  Failing to implement the redirect will cause that the correct Page Authority and Domain Authority not to carry over to the sub domain. Technically heartstone.icy-veins.com and icy-veins.com is to separate domains according to the DNS that is why it is important to ensure that the redirects is in place to carry over any “seo juice” that the old directory had.

        -          Sub domains enhances the user experience of your visitors by keeping to separate themes and topics.  This will have a positive impact on your bounce rate (which is currently sitting at 38% for the last 30 days) and better funnelling for goal conversions (i.e. donate | newsletter signup | advertise on our website

        -          Essentially you are focusing on different products for the same brand

        In the  end of the day it comes down to your personal preference although sub domains will be a better choice to ensure that your different products are split up and reflects better with the search engine results pages.

          Hi Damien,

          There are cases where subdomains are very necessary or inevitable, usually because of technical limitations (and even then, they can usually be worked around via practices like reverse proxy). When you see subdomains in the wild and aren't sure why they're being used, they will often just be legacies - old set-ups that no one wants to change because it would require redirecting old URLs, which is inadvisable if those URLs don't need to be redirected and if they rank well.

          In this case, I'd be really interested to know why the SEO was adamant that the new structure should use subdomains and not subdirectories. Google is much better at working with new subdomains now than it was in years past, but if there is no good reason to use them, subdirectories are still the safer option for SEO purposes, and the content housed on subdirectories should automatically inherit authority from the parent domain. New subdomains seem to be far less likely to inherit this authority, as other responders have said above.

          Find out exactly why the SEO wanted subdomains - if their reasoning isn't solid, you may want to place this content in subdirectories and place 301 redirects from the subdomains to the subdirectories. If you are going to do these redirects, doing them sooner rather than later is advisable as redirection usually comes with a short period of lower rankings / traffic.

          On that note, redirection does usually result with that short period of traffic loss, but that should happen quite quickly and be fixing itself in 2+ weeks, not getting worse.

            Unfortunately yes you will need to 301 the subdomains back to the folder structure.

              Thank you Dean and Caitlin! So, I guess the next step would be to revert the change and switch to directories (using 301-redirects from the subdomains), right?

                I agree with Dean above. Subdomains split your authority. Basically, this means that Google considers wow.icey-veins.com and hearthstone.iceyveins.com as two separate websites in their book. For this reason, folders would have been the far better solution - the site's authority would have remained the same and any additional folders added to the site and resulting links to that folder would have continued to build up the website's authority.

                Don't get me wrong, there are a number of websites that utilize subdomains (typically very large sites). In fact, it use to be very common in year's past. However, subdomains are no longer seen as SEO best practice. ^Caitlin

                  The advice to use sub domains is a wow in it self from an SEO point of view. Sub domains do not pass authority so it's basically like having a new domain for each sub domain.Folders would have been a far better solution in my opinion.

                    Top hierarchy pages vs footer links vs header links

                    Hi All, We want to change some of the linking structure on our website. I think we are repeating some non-important pages at footer menu. So I want to move them as second hierarchy level pages and bring some important pages at footer menu. But I have confusion which pages will get more influence: Top menu or bottom menu or normal pages? What is the best place to link non-important pages; so the link juice will not get diluted by passing through these. And what is the right place for "keyword-pages" which must influence our rankings for such keywords? Again one thing to notice here is we cannot highlight pages which are created in keyword perspective in top menu. Thanks

                    Blog On Subdomain - Do backlinks to the blog posts on Subdomain count as links for main site?

                    I want to put blog on my site.  The IT department is asking that I use a subdomain (myblog.mysite.com) instead of a subfolder (mysite.com/myblog).  I am worried b/c it was my understanding that any links I get to my blog posts (if on subdomain) will not count toward the main site (search engines would view almost as other website).   The main purpose of this blog is to attract backlinks.  That is why I prefer the subfolder location for the Blog. Can anyone tell me if I am thinking about this right? Another solution I am being offered is to use a reverse proxy. Thoughts? Thank you for your time.

                    Drop in traffic after redesign

                    Is it common for a site to see slight traffic drops after a site redesign (containing cleaner code, more usability and basically just being more helpful for the end user)?  A new site of ours went live last Wednesday and has experienced a drop in traffic. If you have seen this in your own site, how did you recover? And how long did the recovery take?

                    How to structure articles on a website.

                    Hi All, Key to a successful website is quality content - so the Gods of Google tell me. Embrace your audience with quality feature rich articles on your products or services, hints and tips, how to, etc. So you build your article page with all the correct criteria; Long Tail Keyword or phrases hitting the URL, heading, 1st sentance, etc. My question is this
                    Let's say you have 30 articles, where would you place the 30 articles for SEO purposes and user experiences. My thought are:
                    1] on the home page create a column with a clear heading "Useful articles" and populate the column with links to all 30 articles.
                    or
                    2] throughout your website create link references to the articles as part of natural information flow.
                    or
                    3] Create a banner or impact logo on the all pages to entice your audience to click and land on dedicated "articles page" Thanks Mark

                    Hi, I have this issue where my website does not appear in Google search results when i have the safe search settings on. If i turn the safe search settings off, my site appears no problem. I'm guessing Google is categorizing my website as adult, which it definitely is not. Has anyone had this issue before? Or does anyone know how to resolve this issue? Any help would be much appreciated. Thanks

                    301 vs 410 redirect: What to use when removing a URL from the website

                    We are in the process of detemining how to handle URLs that are completely removed from our website? Think of these as listings that have an expiration date (i.e. http://www.noodle.org/test-prep/tphU3/sat-group-course). What is the best practice for removing these listings (assuming not many people are linking to them externally). 301 to a general page (i.e. http://www.noodle.org/search/test-prep) Do nothing and leave them up but remove from the site map (as they are no longer useful from a user perspective) return a 404 or 410?

                    Hello everyone, it's me again 😉 I've just got a Pro membership on SeoMoz and I am full of questions. A few days ago I found very interesting tool called: Search Engine Pingler And description of it was like this: Your website or your page was published a long time, but you can not find it on google. Because google has not index your site. Tool Search engine pingler will assist for you. It will ping the URL of your Page up more than 80 servers of google and other search engines. Inform to the search engine come to index your site. So my question is that tool really helps to increase the indexation of the link by search engine like Google, if not, please explain what is a real purpose of it. Thank you to future guru who can give a right answer 🙂
