      Hello, i would like your advice on a dilemma i am facing. I am working a new project that is going to release soon,  thats a network of users with personal profiles seperated in categories for example lets say the categories are colors. So let say i am a member and i belong in red color categorie and i got a page where i update my personal information/cv/resume as well as a personal blog thats on that page. So the main site is giving the option to user to search for members by the criteria of color. My first idea is that all users should own a subdomain (and this is how its developed so far) thats easy to use and since the domain name is really small (just 3 letters) i believe subdomain worth since personal site will be easy to remember. My dilemma is should all users own a subdomain, a subdirectory or both and if both witch one should be the canonical?

      Since it said that search engines treat subdomains as different stand-alone sites, whats best for the main site? to show multiple search results with profiles in subdomains or subdirectories?

      What if i use both? meaning in search results i use search directory url for each profile while same time each profile owns a subdomains as well? and if so which one should be the canonical?

      Thanks in advance,

      C

        This is one of the reasons I love this forum: it requires thinking because many who ask questions are thinking. (think about it;) While I understand what eyepaq is saying in one sense that search engines "could" treat them as stand alone; it appears search engines do/could because as the subdomain holder you are not seeing links going only to the main domain or other subs, you are the one who controls it, can move its hosting, etc.  But, according to Google, they do not in the sense of linking:

        If you own a site that’s on a subdomain (such as googlewebmastercentral.blogspot.com) or in a subfolder (www.google.com/support/webmasters/) and don’t own the root domain, you’ll still only see links from URLs starting with that subdomain or subfolder in your internal links, and all others will be categorized as external links. We’ve made a few backend changes so that these numbers should be even more accurate for you.

        Note that, if you own a root domain like example.com or www.example.com, your number of external links may appear to go down with this change; this is because, as described above, some of the URLs we were previously classifying as external links will have moved into the internal links report. Your total number of links (internal + external) should not be affected by this change.

        So, as for external linking, it is clear that if there ever was a question about domains and subdomains, there is none now. But, that does not mean you should not use subdomains. Eyepaqs point around user abuse is an excellent one, but you should also be monitoring this like a hawk.

        At the end of the day, I would think that using subdirectories is going to be easier if you are planning on a large site. But, the ease you mention for the user with the short domain name is intriguing. I agree with Muhammad on sub domains might get a little expensive and, if your choice is to use both (I wouldn't as it seems to me that you are creating more and more work for your dev team) the canonical should be the subdomain.

        Again, thanks for the thought provoking question.

        Robert

          Hi,

          Since it said that search engines treat subdomains as different stand-alone sites,

          ** Search engines could treat subdomains as different stand alone sites.  Usually they don't. A good example when they do that is the blogspot subdomains - and that is because those are in fact separate stand alone sites.

          In your case however, since it's about users, similar with blogspot somehow - google can treat them at som point as separate websites.

          whats best for the main site? to show multiple search results with profiles in subdomains or subdirectories?

          ** My personal opinion is that from a user point of view you should go with the subdomains as you do right now - it make sense, it's easy for them to use those urls, to link to them and so on.

          You could lose some link equity for the main domain if some or all subdomain will be at some point treated as separate domains but if you put everything on a scale, it will balance as advantages on the subdomain approach anyway.

          What if i use both? meaning in search results i use search directory url for each profile while same time each profile owns a subdomains as well? and if so which one should be the canonical?

          ** To be honest I do see the point / advantages in doing that.

          One other advantage is that if you go with subdomains and google will count them as separate websites, if one of your user is ding something stupid (trying to rank with it and start building gambling and porn links to that sub domain you will be safe with the root domain and the other users won't be affected.

          Hope it helps.

          Edited to underline the word could 🙂

            Hi HaCos,

            Well it depends on how many users are there? thousands of users with thousands of sub domains is an expensive option. Go for user subdirectories instead of sub domains. And as each user got a sub domain too, so make that sub domain canonical of user sub directory. Hope this answers your question.

              How many images should I use in structured data for a product?

              We have a basic printing website that offers business cards. Each type of business card has a few product images. Should we use structured data for all the images, or just the main image? What is your opinion about this? Thanks in advance.

              Should I run my Shopify store on a subdomain or buy a new domain for it?

              I'm planning to set up a subdomain for my Shopify store but I'm not sure if this is the right approach. Should I purchase a separate domain for it? I'm running Wordpress on my website and want to keep it that way. I want to use Shopify for the ecommerce side. I want to link the store from the top nav and of course I'll use CTA's in a variety of ways to point to merchandise and other things on the store side.   Thanks for any help you can offer.

              Should I be using meta robots tags on thank you pages with little content?

              I'm working on a website with hundreds of thank you pages, does it make sense to no follow, no index these pages since there's little content on them? I'm thinking this should save me some crawl budget overall but is there any risk in cutting out the internal links found on the thank you pages? (These are only standard site-wide footer and navigation links.) 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.

              How to handle a blog subdomain on the main sitemap and robots file?

              Hi, I have some confusion about how our blog subdomain is handled in our sitemap.  We have our main website, example.com, and our blog, blog.example.com. Should we list the blog subdomain URL in our main sitemap?  In other words, is listing a subdomain allowed in the root sitemap? What does the final structure look like in terms of the sitemap and robots file?  Specifically: **example.com/sitemap.xml ** would I include a link to our blog subdomain (blog.example.com)? example.com/robots.xml would I include a link to BOTH our main sitemap and blog sitemap? blog.example.com/sitemap.xml would I include a link to our main website URL (even though it's not a subdomain)? blog.example.com/robots.xml does a subdomain need its own robots file? I'm a technical SEO and understand the mechanics of much of on-page SEO.... but for some reason I never found an answer to this specific question and I am wondering how the pros do it.  I appreciate your help with this.

              Better to use specific cities or counties for SEO geographics?

              Hello SEO experts! We are encountering a difficult situation at our marketing firm with a client who wants to optimize her site for keyworks + counties, as she doesn't want to be restricted to one specific city. We have suggested alternate solutions like location pages, utilization of H2's, etc, however, she wants to know the effectiveness of using a specific city (ie: Winona, MN) vs a county (ie: Winona County, MN) for SEO purposes. The research I have conducted thus far hasn't gotten me very far, basically I'm seeing that it all comes back to what people search for (cleaning services in Winona, MN vs. cleaning services in Winona County, MN). Does anyone have any insight into this issue?

              Getting a Sitemap for a Subdomain into Webmaster Tools

              We have a subdomain that is a Wordpress blog, and it takes days, sometimes weeks for most posts to be indexed. We are using the Yoast plugin for SEO, which creates the sitemap.xml file. The problem is that the sitemap.xml file is located at blog.gallerydirect.com/sitemap.xml, and Webmaster Tools will only allow the insertion of the sitemap as a directory under the gallerydirect.com account. Right now, we have the sitemap listed in the robots.txt file, but I really don't know if Google is finding and parsing the sitemap. As far as I can tell, I have three options, and I'd like to get thoughts on which of the three options is the best choice (that is, unless there's an option I haven't thought of): 1. Create a separate Webmaster Tools account for the blog 2. Copy the blog's sitemap.xml file from blog.gallerydirect.com/sitemap.xml to the main web server and list it as something like gallerydirect.com/blogsitemap.xml, then notify Webmaster Tools of the new sitemap on the galllerydirect.com account 3. Do an .htaccess redirect on the blog server, such as RewriteRule ^sitemap.xml http://gallerydirect.com/blogsitemap_index.xml Then notify Webmaster Tools of the new blog sitemap in the gallerydirect.com account. Suggestions on what would be the best approach to be sure that Google is finding and indexing the blog ASAP?

              Will using a service such as Akamai impact on rankings?

              Howdy 🙂 My client has a .com site they are looking at hosting via Akamai - they have offices in various locations, e.g UK, US, AU, RU & in some Asian countries. If they used Akamai, would the best approach be to set up seperate sites per country: .co.uk .com .com.au .ru .sg etc Although my understanding is that Googlebot is located in the US so if it crawled any of those sites it would always get a US IP address? So is the answer perhaps to go with Akamai for the .com only which should target the US market and use different / seperate C class hosts for the others? Thanks! Woj
