      What would you recommend as best practice? Our ecommerce site has a lot of PDFs supporting the product page. Currently they are kept in a sub domain and so are all images.

      Would it be better to keep them all in a subfolder? I've read about blogs being hosted on a subfolder to be better than subdomain but what about pdfs and images?

      thoughts?

        Hi I personally would host them in a subfolder - especially the PDFs as they are likely to gain links and these links will help strengthen your domain.

        However if you have them in a sub-domain they won't have the same benefit from the links as Google essentially treats sub-domains as a separate domain. This will also limit the ranking ability of PDFs as they won't benefit from your domains authority on a sub-domain.

        Have a look at this article for a bit more insight into subfolder vs sub-domain

        - http://www.seomoz.org/blog/understanding-root-domains-subdomains-vs-subfolders-microsites

        I hope this helped..

          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.

          Combining images with text as anchor text

          Hello everyone, I am working to create sub-category pages on our website virtualsheetmusic.com, and I'd like to have your thoughts on using a combination of images and text as anchor text in order to maximize keyword relevancy. Here is an example (I'll keep it simple): Let's take our violin sheet music main category page located at /violin/, which includes the following sub-categories: Christmas Classical Traditional So, the idea is to list the above sub-categories as links on the main violin sheet music page, and if we had to use simple text links, that would be something like: Christmas
          Classical
          Traditional Now, since what we really would like to target are keywords like: "christmas violin sheet music" "classical violin sheet music" "traditional violin sheet music" I would be tempted to make the above links as follows: Christmas violin sheet music
          Classical violin sheet music
          Traditional violin sheet music But I am sure that would be too much overwhelming for the users, even if the best CSS design were applied to it. So, my idea would be to combine images with text, in a way to put those long-tail keywords inside the image ALT tag, so to have links like these: Christmas
          Classical
          Traditional That would allow a much easier way to work the UI , and at the same time keep relevancy for each link. I have seen some of our competitors doing that and they have top-notch results on the SEs. My questions are: 1. Do you see any negative effect of doing this kind of links from the SEO standpoint? 2. Would you suggest any better way to accomplish what I am trying to do? I am eager to know your thoughts about this. Thank you in advance to anyone!

          Href lang in image or video XML sitemaps

          Does anyone know if it is possible/recommended/not recommended to use href lang in image or video XML sitemaps? This had not crossed my mind until recently, but a client asked me this question and I couldn't find any information on this topic.

          Why does Moz recommend subdomains for language-specific websites?

          In Moz's domain recommendations, they recommend subdirectories instead of subdomains (which agrees with my experience), but make an exception for language-specific websites: Since search engines keep different metrics for domains than they do subdomains, it is recommended that webmasters place link-worthy content like blogs in subfolders rather than subdomains. (i.e. www.example.com/blog/ rather than blog.example.com) The notable exceptions to this are language-specific websites. (i.e., en.example.com for the English version of the website). Why are language-specific websites excepted from this advice? Why are subdomains preferable for language-specific websites? Google's advice says subdirectories are fine for language-specific websites, and GSC allows geographic settings at the subdirectory level (which may or may not even be needed, since language-specific sites may not be geographic-specific), so I'm unsure why Moz would suggest using subdirectories in this case.

          Moving blog to a subdomain, how can I help it rank?

          Hi all, We recently moved our blog to a sub-domain where it is hosted on Wordpress. It was very recent and we're actively working on the SEO, but any pointers on getting the subdomain to rank higher than the old blog posts would be terrific. Thanks!

          Turning off a subdomain

          Hi! I'm currently working with http://www.muchbetteradventures.com/. They have a previous version of the site, http://v1.muchbetteradventures.com, as sub domain on their site. I've noticed a whole bunch of indexing issues which I think are caused by this. The v1 site has several thousand pages and ranks organically for a number of terms, but the pages are not relevant for the business at this time. The main site has just over 100 pages. More than 28,400 urls are currently indexed. We are considering turning off the v1 site and noindexing it. There are no real backlinks to it. The only worry is that by removing it, it will be seen as a massive drop in content. Rankings for the main site are currently quite poor, despite good content, a decent link profile and high domain authority. Any thoughts would be much appreciated!

          Subdomain Blog Sitemap link - Add it to regular domain?

          Example of setup:
          www.fancydomain.com
          blog.fancydomain.com Because of certain limitations, I'm told we can't put our blogs at the subdirectory level, so we are hosting our blogs at the subdomain level (blog.fancydomain.com). I've been asked to incorporate the blog's sitemap link on the regular domain, or even in the regular domain's sitemap. 1. Putting the a link to blog.fancydomain.com/sitemap_index.xml in the www.fancydomain.com/sitemap.xml -- isn't this against sitemap.org protocol? 2. Is there even a reason to do this? We do have a link to the blog's home page from the www.fancydomain.com navigation, and the blog is set up with its sitemap and link to the sitemap in the footer. 3. What about just including a text link "Blog Sitemap" (linking to blog.fancydomain.com/sitemap_index.html) in the footer of the www.fancydomain.com (adjacent to the text link "Sitemap" which already exists for the www.fancydomain.com's sitemap. Just trying to make sense of this, and figure out why or if it should be done. Thanks!

          Use of subdomains, subdirectories or both?

          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
