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.

We want to launch in New Zealand which is ends with .co.nz If i duplicate the Australian based site completely on the new .co.nz domain name, would i face duplicate content issues from a SEO standpoint?

Switching from HTTP to HTTPS: 301 redirect or keep both & rel canonical?
Hey Mozzers, I'll be moving several sites from HTTP to HTTPS in the coming weeks (same brand, multiple ccTLDs). We'll start on a low traffic site and test it for 2-4 weeks to see the impact before rolling out across all 8 sites. Ideally, I'd like to simply 301 redirect the HTTP version page to the HTTPS version of the page (to get that potential SEO rankings boost). However, I'm concerned about the potential drop in rankings, links and traffic. I'm thinking of alternative ways and so instead of the 301 redirect approach, I would keep both sites live and accessible, and then add rel canonical on the HTTPS pages to point towards HTTP so that Google keeps the current pages/ links/ indexed as they are today (in this case, HTTPS is more UX than for SEO). Has anyone tried the rel canonical approach, and if so, what were the results? Do you recommend it? Also, for those who have implemented HTTPS, how long did it take for Google to index those pages over the older HTTP pages?

Why is rel="canonical" pointing at a URL with parameters bad?
Context Our website has a large number of crawl issues stemming from duplicate page content (source: Moz). According to an SEO firm which recently audited our website, some amount of these crawl issues are due to URL parameter usage. They have recommended that we "make sure every page has a Rel Canonical tag that points to the non-parameter version of that URL…parameters should never appear in Canonical tags." Here's an example URL where we have parameters in our canonical tag... http://www.chasing-fireflies.com/costumes-dress-up/womens-costumes/ rel="canonical" href="http://www.chasing-fireflies.com/costumes-dress-up/womens-costumes/?pageSize=0&pageSizeBottom=0" /> Our website runs on IBM WebSphere v 7. Questions Why it is important that the rel canonical tag points to a non-parameter URL? What is the extent of the negative impact from having rel canonicals pointing to URLs including parameters? Any advice for correcting this? Thanks for any help!

Duplicate content due to parked domains
I have a main ecommerce website with unique content and decent back links. I had few domains parked on the main website as well specific product pages. These domains had some type in traffic. Some where exact product names. So main main website www.maindomain.com had domain1.com , domain2.com parked on it. Also had domian3.com parked on www.maindomain.com/product1. This caused lot of duplicate content issues. 12 months back, all the parked domains were changed to 301 redirects. I also added all the domains to google webmaster tools. Then removed main directory from google index. Now realize few of the additional domains are indexed and causing duplicate content. My question is what other steps can I take to avoid the duplicate content for my my website 1. Provide change of address in Google search console. Is there any downside in providing change of address pointing to a website? Also domains pointing to a specific url , cannot provide change of address 2. Provide a remove page from google index request in Google search console. It is temporary and last 6 months. Even if the pages are removed from Google index, would google still see them duplicates? 3. Ask google to fetch each url under other domains and submit to google index. This would hopefully remove the urls under domain1.com and doamin2.com eventually due to 301 redirects. 4. Add canonical urls for all pages in the main site. so google will eventually remove content from doman1 and domain2.com due to canonical links. This wil take time for google to update their index 5. Point these domains elsewhere to remove duplicate contents eventually. But it will take time for google to update their index with new non duplicate content. Which of these options are best best to my issue and which ones are potentially dangerous? I would rather not to point these domains elsewhere. Any feedback would be greatly appreciated.

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.

Is their value in linking to PPC landing pages and using rel="canonical"
I have ppc landing pages that are similar to my seo page. The pages are shorter with less text with a focus on converting visitors further along in the purchase cycle. My questions are: 1. Is there a benefit for having the orphan ppc pages indexed or should I no index them? 2. If indexing does provide benefits, should I create links from my site to the ppc pages or should I just submit them in a sitemap? 3. If indexed, should I use rel="canonical" and point the ppc versions to the appropriate organic page? Thanks,

Duplicate content on sites from different countries
Hi, we have a client who currently has a lot of duplicate content with their UK and US website. Both websites are geographically targeted (via google webmaster tools) to their specific location and have the appropriate local domain extension. Is having duplicate content a major issue, since they are in two different countries and geographic regions of the world? Any statement from Google about this? Regards, Bill
