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 content on URL trailing slash
Hello, Some time ago, we accidentally made changes to our site which modified the way urls in links are generated. At once, trailing slashes were added to many urls (only in links). Links that used to send to
Intermediate & Advanced SEO | | yacpro13
example.com/webpage.html Were now linking to
example.com/webpage.html/ Urls in the xml sitemap remained unchanged (no trailing slash). We started noticing duplicate content (because our site renders the same page with or without the trailing shash). We corrected the problematic php url function so that now, all links on the site link to a url without trailing slash. However, Google had time to index these pages. Is implementing 301 redirects required in this case?1 -
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!

Trailing Slashes for Magento CMS pages - 2 URLS - Duplicate content
Hello, Can anyone help me find a solution to Fixing and Creating Magento CMS pages to only use one URL and not two URLS? www.domain.com/testpage www.domain.com/testpage/ I found a previous article that applies to my issue, which is using htaccess to redirect request for pages in magento 301 redirect to slash URL from the non-slash URL. I dont understand the syntax fully in htaccess , but I used this code below. This code below fixed the CMS page redirection but caused issues on other pages, like all my categories and products with this error: "This webpage has a redirect loop ERR_TOO_MANY_REDIRECTS" Assuming you're running at domain root. Change to working directory if needed. RewriteBase / # www check If you're running in a subdirectory, then you'll need to add that in to the redirected url (http://www.mydomain.com/subdirectory/$1 RewriteCond %{HTTP_HOST} !^www. [NC]

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

Canonical link vs root domain
I have a wordpress website installed on http://domain.com/home/ instead of http://domain.com - Does it matter whether I leave it that way with a canonical link from the domain.com to the domain.com/home/ or should I move the wordpress files and database to the root domain?

PDF for link building - avoiding duplicate content
Hello, We've got an article that we're turning into a PDF. Both the article and the PDF will be on our site. This PDF is a good, thorough piece of content on how to choose a product. We're going to strip out all of the links to our in the article and create this PDF so that it will be good for people to reference and even print. Then we're going to do link building through outreach since people will find the article and PDF useful. My question is, how do I use rel="canonical" to make sure that the article and PDF aren't duplicate content? Thanks.
