Upper and lower case spelling = dupe content?
-
Hi All,
I've looking at my Crawl Diagnostics Summary and working on getting my site errors down as low as possible.
One thing I'm noticing is that in the "Other URLs" column I'm seeing a lot of 1s. When I click on the number, it is showing me the exact URL with an upper case category title.
For example, it appears like it's telling me that these two URLs are considered duplicate content:
Is that right? Does google care about upper and lower case spelling?

Thanks guys! This a huge help. I'll get it taken care of.

URLs are case sensitive after the TLD, so these would appear to Google to be duplicate content. Theoretically, those could be two different pages. Ideally, you could 301 redirect all of one to the other. So if you're using lower case /category across your site, you would want to 301 all the /Category URLs to /category.
Some sites correct for capitalization in URLs, and some don't. Do you have internal links using both forms of "category"? If so, you should correct those to one form, as 301's don't pass all your link juice, so you'd create a bit of a leak.

Hi Shawn
URLs are case sensitive; so in the example in your question, yes you have duplicate pages there.
As Category is spelt with both an Upper case and a lower case C you will have two identical pages, which is not good for either Search or User Experience.
Some confirmation for you that it's an absolute must to stick with lower case URLs can be found under Point 10 of "11 Best Practices for URLs" which is a blog post here on SEOmoz from a long time ago by Rand Fishkin which is still extremely valid today.
So it's highly recommended that you 301 Redirect any URLs with Upper case letters in to the corresponding URL that's completely lower case.
Regards
Simon

Duplicate content issues with file download links (diff. versions of a downloadable application)
I'm a little unsure how canonicalisation works with this case. 🙂 We have very regular updates to the application which is available as a download on our site. Obviously, with every update the version number of the file being downloaded changes; and along with it, the URL parameter included when people click the 'Download' button on our site. e.g. mysite.com/download/download.php?f=myapp.1.0.1.exe mysite.com/download/download.php?f=myapp.1.0.2.exe mysite.com/download/download.php?f=myapp.1.0.3.exe, etc In the Moz Site Crawl report all of these links are registering as Duplicate Content. There's no content per se on these pages, all they do is trigger a download of the specified file from our servers. Two questions: Are these links actually hurting our ranking/authority/etc? Would adding a canonical tag to the head of mysite.com/download/download.php solve the crawl issues? Would this catch all of the download.php URLs? i.e. Thanks! Jon

Duplicate content nightmare
Hey Moz Community I ran a crawl test, and there is a lot of duplicate content but I cannot work out why. It seems that when I publish a post secondary urls are being created depending on some tags and categories. Or at least, that is what it looks like. I don't know why this is happening, nor do I know if I need to do anything about it. Help? Please.

URL Parameters causing duplicate content - Login/Registration page
All, I just recently acquired a new client and right away I noticed an abundance of duplicate content being recorded after the moz crawl diagnostics was completed. After a quick digest of the issue, it seems that the majority (90%) of the outlined duplicated content is stemming from the client's Login/Registration page. Upon clicking (without being logged-in) any asset or forum discussion board link within the site, the user is automatically redirected to the Login/Registration page, which seems to create this massive redirect loop associated with dynamic url parameters. Ex. After clicking on a select internal link (asset or discussion board) the user is redirected to the Login/Register page which presents the page and a URL that looks a lot this this: Ex. 1 https://www.clientsite.com/register-login?ReturnUr...xxxx%xxxx%xxxx%...... Ex. 2 https://www.clientsite.com**/register-login?returnurl=/register-login?returnurl=/register-login?returnurl=/page-titl**e/ These URLs seem to becoming larger and larger... The client wants to ensure users have to Login/Register within their site before they're allowed to view the content. This process doesn't allow for any type of preview page to be viewed by a user prior to clicking on the internal link, which in turn doesn't allow any preview pages to be indexed. Right now, Moz is picking up all of the redirect and labeling them as duplicate page content/duplicate page titles based on the Login/Registration page. Questions/Comments: Would it be wise to create preview pages for the asset pages and discussion board pages to allow for proper indexing? - Could this be a CMS issue? Current being used on this is, Kentico. There are thousands of pages being recorded in the crawl as duplicate, however only 14 seem to be indexing with duplicate title tags. 301 or canonical redirect strategy? Moz crawl data issue? Again, this is my first look at this issue, so more information is bound to come out soon! Please let me know if anyone has run into this issue and if you have a possible solution to get rid of this redirect loop process. Thanks! -T

Duplicate Content in Blog
Hi, SEOMoz on-page analysis is reporting that our blog has duplicate content when technically it doesn't. Is this something that we need to address as it will actually be hurting our ranking or is this just a SEOMoz software quirk? There is 100+ example like this but here is one example. SEOMoz is reporting http://www.invoicestudio.com/Blog/author/InvoiceStudio?page=1 and http://www.invoicestudio.com/Blog/author/InvoiceStudio?page=2 as a duplicate content and Title Tag. Thanks Andrew

Sorting Dupe Content Pages
Hi, I'm no excel pro, and I'm having a bit of a challenge interpreting the Crawl Diagnostics export .csv file. I'd like to see at a glance which of my pages (and I have many) are the worst offenders for dupe content – ie. which have the most "Other URLs" associated with them. Thanks, would appreciate any advice on how other people are using this data, and/or how 'Moz recommends to do it. 🙂

Why does my crawl diagnostics show duplicate content
My crawl diagnostics show duplicate content at mysite.com and mysite.com/index.html which are essentially the same file.
