Help With Preferred Domain Settings, 301 and Duplicate Content
-
I've seen some good threads developed on this topic in the Q&A archives, but feel this topic deserves a fresh perspective as many of the discussion were almost 4 years old.
My webmaster tools preferred domain setting is currently non www. I didn't set the preferred domain this way, it was like this when I first started using WM tools.
However, I have built the majority of my links with the www, which I've always viewed as part of the web address.
When I put my site into an SEO Moz campaign it recognized the www version as a subdomain which I thought was strange, but now I realize it's due to the www vs. non www preferred domain distinction.
A look at site:mysite.com shows that Google is indexing both the www and non www version of the site. My site appears healthy in terms of traffic, but my sense is that a few technical SEO items are holding me back from a breakthrough.
QUESTION to the SEOmoz community:
What the hell should I do? Change the preferred domain settings? 301 redirect from non www domain to the www domain?
Google suggests this: "Once you've set your preferred domain, you may want to use a 301 redirect to redirect traffic from your non-preferred domain, so that other search engines and visitors know which version you prefer."
Any insight would be greatly appreciated.

The worst thing you can do is nothing.
Above is 5 examples of URLs which COULD all lead to the same page. There are numerous other possibilities as well. If you don't let Google know which version of the page is correct, then you will suffer the consequences of duplicate content.
What happens is Google doesn't know which page is correct. They will pick one of the non-www versions because that is what your Google WMT is set up to do. Meanwhile other versions of the pages are being used.
You are sending your link juice to a page, but it is a complete waste as it is not being considered by Google for SERP. You MUST resolve this issue if you care about SEO at all.

Thanks Ryan. So, if most of the links (including all internal links) are built with the www format then it is wise to change preferred domain settings to www and redirect the non www to the www domain?
Am I likely to damage rankings/traffic by doing this? What happens if I just leave it as is?
-
You are welcome to do so. Go to Google WMT, change your current option to the www, then adjust your .htaccess file as Steven suggested.
Also, canonicalize your pages to help ensure this issue can't happen again. Your .htaccess changes will work as long as the file is there, but things happen so it's better to be covered.

Guys,
Thanks for the input. I just want to do what is best for traffic and the site. I don't want to do anything that is going to tank my rankings and visitors.
I don't get alot of type in traffic.
www is the main way the links have been built, why not just redirect those to the non www version?
-
As Ryan said, make a decision. The easiest way to make sure either of your decisions sticks is to use an htaccess file and rewrite to your preferred.
If using the www version:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^[0-9]+(.[0-9]+){3} [OR]
RewriteCond %{HTTP_HOST} ^mydomain.com [NC]
RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301]if using the non www version:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.mydomain.com [NC]
RewriteRule ^(.*)$ http://mydomain.com/$1 [L,R=301]A few other questions to keep in mind:
Do you get a lot of type-in traffic?
Do they tend to type the www?
In the SERP it is easier to read the domain name with out the www if looking for a specific domain name. Do you have a brand built where people just say your domain name?
-
You need to make a decision. Do you want your site address to be seen with or without the www?
Try to assess which version of your URL would require the least number of re-directs. You mentioned the links you built mostly include the www. Take a look at all of your links. You may have a higher number of organic links without the www. Evaluate all the links, then make a decision.
Once you make a decision, stick with it. Canonicalize all your pages with the correct version of the URL. Search your site for all internal links and standardize them.
While you are on this project standardize whether you use a "/" on the end of your url as well. www.mysite.com is not the same as www.mysite.com/. I make this suggestion because if you will go through the painful process of standardizing your site for the www issue, you should resolve all issues at once.

301 Redirect Only Home Page/Root Domain via Domain Registrar Only
Hi All, I am really concerned about doing a 301 redirect. This is my situation: Both Current and New Domain is registered with a local domain registrar (similar to GoDaddy but a local version) Current Domain: Servers are pointing to Wix servers and the website is built and hosted with Wix I would like to do a 301 redirect but would like to do it in the following way with a couple of factors to keep in mind: 99% of my link are only pointed to the home page/root domain only. Not to subdirectories. New Domain: I will register this with wix with a new plan but keep the exact sitemap and composition of current website and launch with new domain. Current Domain: I want to change server pointing to wix to point to local domain registrar servers. Then do a 301 redirect for only the home page/root domain to point to the new domain listed with wix. So 301 is done via local registrar and not via Wix. Another point to mention is it will also change from Http to Https as well as a name change. Your comments on the above will be greatly appreciated and as to whether there is risk in trying to do a 301 redirect as above. Doing it as above it also cheaper if I do the 301 via the wix platform I will need to register a full new premium plan and run it concurrently to the old plan whereas if I do it as mentioned above will only have the additional domain annual fee. Look forward to your comments. Mike

How bad is duplicate content for ecommerce sites?
We have multiple eCommerce sites which not only share products across domains but also across categories within a single domain. Examples: http://www.artisancraftedhome.com/sinks-tubs/kitchen-sinks/two-tone-sinks/medium-rounded-front-farmhouse-sink-two-tone-scroll http://www.coppersinksonline.com/copper-kitchen-and-farmhouse-sinks/two-tone-kitchen-farmhouse-sinks/medium-rounded-front-farmhouse-sink-two-tone-scroll http://www.coppersinksonline.com/copper-sinks-on-sale/medium-rounded-front-farmhouse-sink-two-tone-scroll We have selected canonical links for each domain but I need to know if this practice is having a negative impact on my SEO.

Duplicate content on product pages
Hi, We are considering the impact when you want to deliver content directly on the product pages. If the products were manufactured in a specific way and its the same process across 100 other products you might want to tell your readers about it. If you were to believe the product page was the best place to deliver this information for your readers then you could potentially be creating mass content duplication. Especially as the storytelling of the product could equate to 60% of the page content this could really flag as duplication. Our options would appear to be:1. Instead add the content as a link on each product page to one centralised URL and risk taking users away from the product page (not going to help with conversion rate or designers plans)2. Put the content behind some javascript which requires interaction hopefully deterring the search engine from crawling the content (doesn't fit the designers plans & users have to interact which is a big ask)3. Assign one product as a canonical and risk the other products not appearing in search for relevant searches4. Leave the copy as crawlable and risk being marked down or de-indexed for duplicated contentIts seems the search engines do not offer a way for us to serve this great content to our readers with out being at risk of going against guidelines or the search engines not being able to crawl it.How would you suggest a site should go about this for optimal results?

Implications of posting duplicate blog content on external domains?
I've had a few questions around the blog content on our site. Some of our vendors and partners have expressed interest in posting some of that content on their domains. What are the implications if we were to post copies of our blog posts on other domains? Should this be avoided or are there circumstances that this type of program would make sense?

Multiply domains and duplicate content confusion
I've just found out that a client has multiple domains which are being indexed by google and so leading me to worry that they will be penalised for duplicate content. Wondered if anyone could confirm a) are we likely to be penalised? and b) what should we do about it? (i'm thinking just 301 redirect each domain to the main www.clientdomain.com...?). Actual domain = www.clientdomain.com But these also exist: www.hostmastr.clientdomain.com www.pop.clientdomain.com www.subscribers.clientdomain.com www.www2.clientdomain.com www.wwwww.clientdomain.com ps I have NO idea how/why all these domains exist I really appreciate any expertise on this issue, many thanks!

Duplicate content in Webmaster tools, is this bad?
We launched a new site, and we did a 301 redirect to every page. I have over 5k duplicate meta tags and title tags. It shows the old page and the new page as having the same title tag and meta description. This isn't true, we changed the titles and meta description, but it still shows up like that. What would cause that?

How to resolve Duplicate Page Content issue for root domain & index.html?
SEOMoz returns a Duplicate Page Content error for a website's index page, with both domain.com and domain.com/index.html isted seperately. We had a rewrite in the htacess file, but for some reason this has not had an impact and we have since removed it. What's the best way (in an HTML website) to ensure all index.html links are automatically redirected to the root domain and these aren't seen as two separate pages?
