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,

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.

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.

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.

Will using CDN Affect SEO?
I'm got a website with a slider and each of the 6 slides has a 5-second video background. The website is B2B and the user profile for the website is employees at Fortune 1000 companies in the United States using desktop computers to browse. The videos are highly optimized and we did testing using various browsers and bandwidth connections to determine the videos loaded fast enough on down to a 15mbit/s connection (which is pretty low by today's average U.S. business bandwidths.) We tried hosting the videos on Vimeo and YouTube but it caused issues in the timing of the slide show display. (I've not seen any other website do what we do the way we do it. Most sites have a single video background with a single text overlay on top.) The downside to this is that loading all those videos produces a lot of bandwidth usage for our server. The website is serving a niche service industry though so we're not exceeding our current limits. I'm wondering though might there be some benefit to hosting just the video files on a CDN? Obviously that would mean lest bandwidth usage for our server, and possibly quicker load times where the CDN server is closer to the user than our server. But are there benefits or downsides from an SEO perspective noting that I'm proposing only putting the videos on the CDN, not the entire web page.

Using H3 before or instead of an H2...
My designer and I have been having an argument: we have a blog with short, 400 words posts. They have an H1 with nice keywords and a catchy title, and then a few subheadings. I don't like making the subheadings H2, because the font looks way too large in Wordpress, so my designer wants to make them all H4s, so the font looks to be a nicer size. Here's my problem with that and why I usually just bold the subheadings: Is it really bad to put a bunch of H4s right under an H1, with not H2's or 3's to separate? I'm reading different arguments on the internet about this and gladly welcome more debate and/or case studies. Thank you!

Duplicating content from manufacturer for client site and using canonical reference.
We manage content for many clients in the same industry, and many of them wish to keep their customers on their individualized websites (understandably). In order to do this, we have duplicated content in part from the manufacturers' pages for several "models" on the client's sites. We have put in a Canonical reference at the start of the content directing back to the manufacturer's page where we duplicated some of the content. We have only done a handful of pages while we figure out the canonical reference potential issue. So, my questions are: Is this necessary? Does this hurt, help or not do anything SEO-wise for our ranking of the site? Thanks!

Should we host our magazine on a subdomain of E-com site or its own domain?
We host a online fashion magazine on a subdomain of our e-commerce site. Currently we host the blog which is word press based on a subdomain ex: stylemag.xxxxxxx.com First question is are all the links from our blog considered internal links? They do not show in the back links profile. Also would it be better to host this on its own domain? Second question Is my main URL getting credit for the unique content published to the blog on the subdomain and if so is it helping the overall SEO of my website more then if it and the links were hosted on its own wordpress.com

Meta-description not used at all times
Hi all We are marketing an e-commerce site and seem to have a weird issue. For some reason the clearly specified meta description is not being used in the SERPs. Had a look in the source but all tags seems to be there. The site can be found here:

Shall I use a 301 or 302 redirect when people leave the company?
Hello, At my company, we have instances where client-facing people leave the company and so we need to remove their profile page from the website. As opposed to people receiving a 404 when they search for them, I thought it would be best to divert visitors to a generic landing page to explain that the person they are looking for has left the company with details on how to get in touch. I'm tempted to use a 302 redirect so the person they are searching for stays in the search results longer. But longer-term, will this cause any harm? Should it be eventually be turned into a 301 redirect? Or should I just use a 301 in the first instance. Thanks in advance, Stu

Using Canonical Attribute
Hi All, I am hoping you can help me? We have recently migrated to the Umbraco CMS and now have duplicate versions of the same page showing on different URLs. My understanding is that this is one of the major reasons for the rel=canonical tag. So am I right in saying that if I add the following to the page that I want to rank then this will work? I'm just a little worried as I have read some horror stories of people implementing this attribute incorrectly and getting into trouble. Thank you in advance

Pros and Cons of new subdomain and redirecting old subdomain?
Hi guys, I am thinking about redirecting the ranking subdoman to a new subdomain which has my main keyword within it. I am trying to outrank an exact match competitor and don't seem to be able to do so. For example: page.example.com would be my existing ranking URL which is very powerful, and I am thinking about redirecting this to a new URL being keywordpage.example.com What are your thoughts on do this? Thanks B
