Case Sensitive URLs, Duplicate Content & Link Rel Canonical
-
I have a site where URLs are case sensitive. In some cases the lowercase URL is being indexed and in others the mixed case URL is being indexed. This is leading to duplicate content issues on the site.
The site is using link rel canonical to specify a preferred URL in some cases however there is no consistency whether the URLs are lowercase or mixed case. On some pages the link rel canonical tag points to the lowercase URL, on others it points to the mixed case URL.
Ideally I'd like to update all link rel canonical tags and internal links throughout the site to use the lowercase URL however I'm apprehensive!
My question is as follows:
If I where to specify the lowercase URL across the site in addition to updating internal links to use lowercase URLs, could this have a negative impact where the mixed case URL is the one currently indexed?
Hope this makes sense!

Thanks Hutch and Ryan, great answers and exactly what I need. Appreciate it!

In addition to using rel=canonical for the lowercase version of your URLs you should also consider implementing redirection from uppercase to lowercase. A regex expert should be able to write the redirect script you'll need to add to your .htaccess file in order to change upper to lowercase. Cheers!

While you might see a small down tick in the beginning as Google indexes and updates, overall you should not suffer any long term negative effects from standardizing your URI structure.

Duplicate URLs ending with #!
Hi guys, Does anyone know why a site can contain duplicate URLs ending with hastag & exclamation mark e.g. https://site.com.au/#! We are finding a lot of these URLs (as duplicates) and i was wondering what they are from developer standpoint? And do you think it's worth the time and effort adding a rel canonical tag or 301 to these URLs eventhough they're not getting indexed by Google? Cheers, Chris

Duplicate content on recruitment website
Hi everyone, It seems that Panda 4.2 has hit some industries more than others. I just started working on a website, that has no manual action, but the organic traffic has dropped massively in the last few months. Their external linking profile seems to be fine, but I suspect usability issues, especially the duplication may be the reason. The website is a recruitment website in a specific industry only. However, they posts jobs for their clients, that can be very similar, and in the same time they can have 20 jobs with the same title and very similar job descriptions. The website currently have over 200 pages with potential duplicate content. Additionally, these jobs get posted on job portals, with the same content (Happens automatically through a feed). The questions here are: How bad would this be for the website usability, and would it be the reason the traffic went down? Is this the affect of Panda 4.2 that is still rolling What can be done to resolve these issues? Thank you in advance.

Removing duplicate content
Due to URL changes and parameters on our ecommerce sites, we have a massive amount of duplicate pages indexed by google, sometimes up to 5 duplicate pages with different URLs. 1. We've instituted canonical tags site wide. 2. We are using the parameters function in Webmaster Tools. 3. We are using 301 redirects on all of the obsolete URLs 4. I have had many of the pages fetched so that Google can see and index the 301s and canonicals. 5. I created HTML sitemaps with the duplicate URLs, and had Google fetch and index the sitemap so that the dupes would get crawled and deindexed. None of these seems to be terribly effective. Google is indexing pages with parameters in spite of the parameter (clicksource) being called out in GWT. Pages with obsolete URLs are indexed in spite of them having 301 redirects. Google also appears to be ignoring many of our canonical tags as well, despite the pages being identical. Any ideas on how to clean up the mess?

Internal links and URL shortners
Hi guys, what are your thoughts using bit.ly links as internal links on blog posts of a website? Some posts have 4/5 bit.ly links going to other pages of our website (noindexed pages). I have nofollowed them so no seo value is lost, also the links are going to noindexed pages so no need to pass seo value directly. However what are your thoughts on how Google will see internal links which have essential become re-direct links? They are bit.ly links going to result pages basically. Am I also to assume the tracking for internal links would also be better using google analytics functionality? is bit.ly accurate for tracking clicks? Any advice much appreciated, I just wanted to double check this.

Partial duplicate content and canonical tags
Hi - I am rebuilding a consumer website, and each product page will contain a unique product image, and a sentence or two about the product (and we tend to use a lot of the same words in different ways across products). I'd like to have a tabbed area below the product info that talks about the overall product line, and this content would be duplicate across all the product pages (a "Why use our products" type of thing). I'd have this duplicate content also living on its own URL's so they can be found alone in the SERP's. Question is, do I need to add the canonical tag to this page, since there's partial duplicate content on the product pages? And if I did that, would my product pages go un-indexed?? I understand how to handle completely duplicated content, it's the partial duplicate that I'm having difficulty figuring out.

International SEO - cannibalisation and duplicate content
Hello all, I look after (in house) 3 domains for one niche travel business across three TLDs: .com .com.au and co.uk and a fourth domain on a co.nz TLD which was recently removed from Googles index. Symptoms: For the past 12 months we have been experiencing canibalisation in the SERPs (namely .com.au being rendered in .com) and Panda related ranking devaluations between our .com site and com.au site. Around 12 months ago the .com TLD was hit hard (80% drop in target KWs) by Panda (probably) and we began to action the below changes. Around 6 weeks ago our .com TLD saw big overnight increases in rankings (to date a 70% averaged increase). However, almost to the same percentage we saw in the .com TLD we suffered significant drops in our .com.au rankings. Basically Google seemed to switch its attention from .com TLD to the .com.au TLD. Note: Each TLD is over 6 years old, we've never proactively gone after links (Penguin) and have always aimed for quality in an often spammy industry. **Have done: ** Adding HREF LANG markup to all pages on all domain Each TLD uses local vernacular e.g for the .com site is American Each TLD has pricing in the regional currency Each TLD has details of the respective local offices, the copy references the lacation, we have significant press coverage in each country like The Guardian for our .co.uk site and Sydney Morning Herlad for our Australia site Targeting each site to its respective market in WMT Each TLDs core-pages (within 3 clicks of the primary nav) are 100% unique We're continuing to re-write and publish unique content to each TLD on a weekly basis As the .co.nz site drove such little traffic re-wrting we added no-idex and the TLD has almost compelte dissapread (16% of pages remain) from the SERPs. XML sitemaps Google + profile for each TLD **Have not done: ** Hosted each TLD on a local server Around 600 pages per TLD are duplicated across all TLDs (roughly 50% of all content). These are way down the IA but still duplicated. Images/video sources from local servers Added address and contact details using SCHEMA markup Any help, advice or just validation on this subject would be appreciated! Kian

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

Are duplicate links on same page alright?
If I have a homepage with category links, is it alright for those category links to appear in the footer as well, or should you never have duplicate links on one page? Can you please give a reason why as well? Thanks!
