Duplicate Content www vs. non-www and best practices
-
I have a customer who had prior help on his website and I noticed a 301 redirect in his .htaccess
Rule for duplicate content removal : www.domain.com vs domain.com
RewriteCond %{HTTP_HOST} ^MY-CUSTOMER-SITE.com [NC]
RewriteRule (.*) http://www.MY-CUSTOMER-SITE.com/$1 [R=301,L,NC]The result of this rule is that i type MY-CUSTOMER-SITE.com in the browser and it redirects to www.MY-CUSTOMER-SITE.com
I wonder if this is causing issues in SERPS. If I have some inbound links pointing to www.MY-CUSTOMER-SITE.com and some pointing to MY-CUSTOMER-SITE.com, I would think that this rewrite isn't necessary as it would seem that Googlebot is smart enough to know that these aren't two sites.
-----Can you comment on whether this is a best practice for all domains?
-----I've run a report for backlinks. If my thought is true that there are some pointing to www.www.MY-CUSTOMER-SITE.com and some to the www.MY-CUSTOMER-SITE.com, is there any value in addressing this? -

Absolutely NOT, unfortunately. Search engines specifically consider these two versions of the URLS to be two totally different sites. The redirect rule you currently have is specifically in place to correct this problem so the two versions of your site (in the eyes of the engines) aren't competing with each other.
The previous developer knew what he was doing. Leave the redirect as-is. Just be careful that all links you create use the primary version of the URL - you'll retain a bit more "link juice" that way than having them go through the redirect. (i.e. always write links as www.my-customer-site.com/whatever for links in content, menus, incoming links where possible)
Paul
P.S. For proof that search engines consider those URLs different sites, Google's own Webmaster Tools has a setting where you can tell Google which version of the site URL you want to be primary. Much better to do this with a proper 301-redirect though so that you can tell ALL search engines, not just Google.

Yes, it is.
-----I've run a report for backlinks. If my thought is true that there are some pointing to www.www.MY-CUSTOMER-SITE.com and some to the www.MY-CUSTOMER-SITE.com, is there any value in addressing this?
You shouldn't worry about that at all. 301's are just fine. They don't only redirect visitors, search engines like Google also follow them to pass authority signals to the redirected page.

You want to commit to one and put a 301 on the other. Googlebot should be smart enough, but it isn't really. Some things aren't best to be left to chance.
Here's the Moz 301 redirect article: http://moz.com/learn/seo/redirection
Edit: Here's another article about www.mysite.com vs mysite.com http://www.stepforth.com/resources/web-marketing-knowledgebase/non-www-redirect/#.UlbGl1Cko2s
-
Ideally one version of the site should redirect to the other version using a 301 to transfer any link juice from one version of the domain to the other. In an issue where both versions have links pointing to them, the best solution is to see which version has the highest domain authority and the most links and use that as your preferred domain.

Will I be flagged for duplicate content by Google?
Hi Moz community, Had a question regarding duplicate content that I can't seem to find the answer to on Google. My agency is working on a large number of franchisee websites (over 40) for one client, a print franchise, that wants a refresh of new copy and SEO. Each print shop has their own 'microsite', though all services and products are the same, the only difference being the location. Each microsite has its own unique domain. To avoid writing the same content over and over in 40+ variations, would all the websites be flagged by Google for duplicate content if we were to use the same base copy, with the only changes being to the store locations (i.e. where we mention Toronto print shop on one site may change to Kelowna print shop on another)? Since the print franchise owns all the domains, I'm wondering if that would be a problem since the sites aren't really competing with one another. Any input would be greatly appreciated. Thanks again!

301 redirect hops from non-https and www
It's best practice to minimize the amount of 301 redirect hops. Ideally only one redirect hop. It's also best practice to 301 redirect (or at least canonical) your non-https and/or your non-www (or www) to the canonical protocol/subdomain. The simplest (and possibly the most common) way to implement canonical protocol/subdomain redirects is through a load balancer or before your app processes the request. Both of which will just blanket 301 to the canonical domain/protocol regardless if the path exists or not In which case, you could have: Two hops. i.e. hop #1 http://example.com/foo to https://example.com/foo, hop #2 https://example.com/foo to https://example.com/bar 301 to a 404. Let's say https://example.com/dog never existed, but somebody for whatever reason linked to it (maybe a typo). If I request https://www.example.com/dog, the load balancer would 301 to a 404 page. Either scenario above should be fairly rare. However, you can't control how people link to you. Should I care about either above scenario? I could have my app attempt to check if the page exists before forwarding, but that code could be complicated.

Best Practices for Converting PDFs to HTML
We're working with a client who gets about 80% of their organic, inbound search traffic from links to PDF files on their site. Obviously, this isn't ideal, because someone who just downloads a PDF file directly from a Google query is unlikely to interact with the site in any other way. I'm looking to develop a plan to convert those PDF files to HTML content, and try to get at least some of those visitors to convert into subscribers. What's the best way to go about this? My plan so far is: Develop HTML landing pages for each of the popular PDFs, with the content from the PDF, as well as the option to download the PDF with an email signup. Gradually implement 301 redirects for the existing PDFs, and see what that does to our inbound SEO traffic. I don't want to create a dip in traffic, although our current "direct to inbound" traffic is largely useless. Are their things I should watch out for? Will I get penalized by Google for redirecting a PDF to HTML content? Other things I should be aware of?

Artist Bios on Multiple Pages: Duplicate Content or not?
I am currently working on an eComm site for a company that sells art prints. On each print's page, there is a bio about the artist followed by a couple of paragraphs about the print. My concern is that some artists have hundreds of prints on this site, and the bio is reprinted on every page,which makes sense from a usability standpoint, but I am concerned that it will trigger a duplicate content penalty from Google. Some people are trying to convince me that Google won't penalize for this content, since the intent is not to game the SERPs. However, I'm not confident that this isn't being penalized already, or that it won't be in the near future. Because it is just a section of text that is duplicated, but the rest of the text on each page is original, I can't use the rel=canonical tag. I've thought about putting each artist bio into a graphic, but that is a huge undertaking, and not the most elegant solution. Could I put the bio on a separate page with only the artist's info and then place that data on each print page using an <iframe>and then put a noindex,nofollow in the robots.txt file?</p> <p>Is there a better solution? Is this effort even necessary?</p> <p>Thoughts?</p></iframe>

Copying my Facebook content to website considered duplicate content?
I write career advice on Facebook on a daily basis. On my homepage users can see the most recent 4-5 feeds (using FB social media plugin). I am thinking to create a page on my website where visitors can see all my previous FB feeds. Would this be considered duplicate content if I copy paste the info, but if I use a Facebook social media plugin then it is not considered duplicate content? I am working on increasing content on my website and feel incorporating FB feeds would make sense. thank you

How to Remove Joomla Canonical and Duplicate Page Content
I've attempted to follow advice from the Q&A section. Currently on the site www.cherrycreekspine.com, I've edited the .htaccess file to help with 301s - all pages redirect to www.cherrycreekspine.com. Secondly, I'd added the canonical statement in the header of the web pages. I have cut the Duplicate Page Content in half ... now I have a remaining 40 pages to fix up. This is my practice site to try and understand what SEOmoz can do for me. I've looked at some of your videos on Youtube ... I feel like I'm scrambling around to the Q&A and the internet to understand this product. I'm reading the beginners guide.... any other resources would be helpful.

Duplicate Content | eBay
My client is generating templates for his eBay template based on content he has on his eCommerce platform. I'm 100% sure this will cause duplicate content issues. My question is this.. and I'm not sure where eBay policy stands with this but adding the canonical tag to the template.. will this work if it's coming from a different page i.e. eBay? Update: I'm not finding any information regarding this on the eBay policy's: http://ocs.ebay.com/ws/eBayISAPI.dll?CustomerSupport&action=0&searchstring=canonical So it does look like I can have rel="canonical" tag in custom eBay templates but I'm concern this can be considered: "cheating" since rel="canonical is actually a 301 but as this says: http://googlewebmastercentral.blogspot.com/2009/12/handling-legitimate-cross-domain.html it's legitimately duplicate content. The question is now: should I add it or not? UPDATE seems eBay templates are embedded in a iframe but the snap shot on google actually shows the template. This makes me wonder how they are handling iframes now. looking at http://www.webmaster-toolkit.com/search-engine-simulator.shtml does shows the content inside the iframe. Interesting. Anyone else have feedback?
