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.

Upper and lower case URLS coming up as duplicate content
Hey guys and gals, I'm having a frustrating time with an issue. Our site has around 10 pages that are coming up as duplicate content/ duplicate title. I'm not sure what I can do to fix this. I was going to attempt to 301 direct the upper case to lower but I'm worried how this will affect our SEO. can anyone offer some insight on what I should be doing? Update: What I'm trying to figure out is what I should do for our URL's. For example, when I run an audit I'm getting two different pages: aaa.com/BusinessAgreement.com and also aaa.com/businessagreement.com. We don't have two pages but for some reason, Google thinks we do.

Woocommerce SEO & Duplicate content?
Hi Moz fellows, I'm new to Woocommerce and couldn't find help on Google about certain SEO-related things. All my past projects were simple 5 pages websites + a blog, so I would just no-index categories, tags and archives to eliminate duplicate content errors. But with Woocommerce Product categories and tags, I've noticed that many e-Commerce websites with a high domain authority actually rank for certain keywords just by having their category/tags indexed. For example keyword 'hippie clothes' = etsy.com/category/hippie-clothes (fictional example) The problem is that if I have 100 products and 10 categories & tags on my site it creates THOUSANDS of duplicate content errors, but If I 'non index' categories and tags they will never rank well once my domain authority rises... Anyone has experience/comments about this? I use SEO by Yoast plugin. Your help is greatly appreciated! Thank you in advance. -Marc

No-index pages with duplicate content?
Hello, I have an e-commerce website selling about 20 000 different products. For the most used of those products, I created unique high quality content. The content has been written by a professional player that describes how and why those are useful which is of huge interest to buyers. It would cost too much to write that high quality content for 20 000 different products, but we still have to sell them. Therefore, our idea was to no-index the products that only have the same copy-paste descriptions all other websites have. Do you think it's better to do that or to just let everything indexed normally since we might get search traffic from those pages? Thanks a lot for your help!

URL Value: Menu Links vs Body Content Links
Hi All, I'm a little confused. I have read a number of articles from authority sites that give mixed signals over the importance of menu links vs body content links. It is suggested that whilst all menu links spread link juice equally, Google does not see them as favourably. Inserting a link within the body will add more link juice value to the desired page. Any thoughts would be appreciated. Thanks Mark

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.

Yoast & rel canonical for paginated Wordpress URLs
Hello, our Wordpress blog at http://www.jobs.ca/career-resources has a rel canonical issue since we added pagination to the front page and category-pages. We're using Yoast and it's incorrectly applying a rel-canonical meta tag referencing page 1 on page 2, 3, etc. This is a known misuse of the rel-canonical tag (per Google's Webmaster Blog - http://googlewebmastercentral.blogspot.ca/2013/04/5-common-mistakes-with-relcanonical.html, which says rel-canonical should be replaced with rel-prev and rel-next for page 2, 3, etc.). We don't see a way to specify anywhere in Yoast's options to correct this behaviour for page 2, 3, etc. Yoast allows you to override a page's canonical URL, otherwise it automatically uses the Wordpress permalink. My question is, does anyone know how to configure Yoast to properly replace rel-canonical tags with rel-prev and rel-next for paginated URLs, or do I need to look at another plugin or customize the behavior directly in my child theme code? This issue was brought up here as well: http://moz.com/community/q/canonical-help, but the only response did not relate to Yoast. (We're using Wordpress 3.6.1 and Yoast "Wordpress SEO" 1.4.18)

Do I need to use rel="canonical" on pages with no external links?
I know having rel="canonical" for each page on my website is not a bad practice... but how necessary is it for pages that don't have any external links pointing to them? I have my own opinions on this, to be fair - but I'd love to get a consensus before I start trying to customize which URLs have/don't have it included. Thank you.

How Rel=Prev & Rel=Next work for me?
I have implemented Rel=Prev & Rel=Next tag on my website. I would like to give example URL to know more about it. http://www.vistapatioumbrellas.com/market-umbrellas?limit=40&p=3 http://www.vistapatioumbrellas.com/market-umbrellas?limit=40&p=4 http://www.vistapatioumbrellas.com/market-umbrellas?limit=40&p=5 Right now, I have blocked paginated pages by Robots.txt by following query. Disallow: /*?p= I have removed disallow syntax from Robots.txt for paginated pages. But, I have confusion with duplicate page title. If you will check all 3 pages so you will find out duplicate page title across all pages. I know that, duplicate page title is harmful for SEO. Will Google crawl + index all paginated pages? If yes so which page will get maximum benefits in organic ranking? Is there any specific way which may help me to solve this issue?
