Why are my pages getting duplicate content errors?
-
Studying the Duplicate Page Content report reveals that all (or many) of my pages are getting flagged as having duplicate content because the crawler thinks there are two versions of the same page:
http://www.mapsalive.com/Features/audio.aspx
http://www.mapsalive.com/Features/Audio.aspx
The only difference is the capitalization. We don't have two versions of the page so I don't understand what I'm missing or how to correct this. Anyone have any thoughts for what to look for?

Dr. Pete doesn't cover case (though it's mentioned in the comments), but just about everything else you might want to know about duplicate content is talked about at http://www.seomoz.org/blog/duplicate-content-in-a-post-panda-world, including ways to remedy it. It sounds like you've got a plan here, but I'm also adding it for the benefit of others looking at this thread.

I think this is one of the most overlooked duplicate content issues. Not sure why it's not talked about as much as it is. I quite often have been using upper and lowercase intermittently. E.g., mysite.com/Las-Vegas/ and mysite.com/las-vegas/, not knowing it made any difference.
I guess a .htaccess rewrite to all lowercase is in order. Thanks SEOMoz. You guys rock.

Glad to be of help Janice.
From a readability perspective, in which case I'd suggest to have all lower case.
-
Well, it is a Windows server and my understanding is that it is case-insensitive, but I'll verify this with our hosting provider. Nevertheless, would it be preferable to set up the rewrite from the mixed case names to all lowercase names or vice versa? Or perhaps it doesn't matter.
Thanks for your help with this - lots to learn and work through with these tools.
-
If the server allows upper case and lower case then from a technical perspective they could both be different files. Like having www.domain.com and domain.com point to the same home page - they may be the same, but technically they could be two different places.
The solution should be set up to not require having to do a rewrite every time a new page is created. It should be automatic.
-
I understand your answer and about setting up rewrites, but what I really want to know is why there are two pages listed (one uppercase, one lowercase) when there is only one physical page on the site. All links within the site point to the page using the uppercase name.
I don't want to have to add a rewrite for the lowercase name every time I add a page to the site - this doesn't seem right which is why I'm wondering if there is something else wrong.
-
Janice,
The proper solution would be to have the site set up at the server level to automatically rewrite URLs so they have one consistent pattern (typically all lower case). And to make sure all links within the site pointing to other pages on the site use that preferred capitalization method. While having Canonical tags can help alleviate the problem, they're not a best practices "only" solution. So speak with the site administrator or programmer to get the rewrite functionality implemented.

Duplicate Content from Wordpress Template
Hi Wondering if anyone can help, my site has flagged up with duplicate content on almost every page, i think this is because the person who set up the site created a lot of template pages which are using the same code but have slightly different features on. How would I go about resolving this? Would I need to recode every template page they have created?

Duplicate Page Title Crawl Error Issue
In the last crawl for on of our client websites the duplicate page title and page content numbers were very high. They are reading every page twice. http://www.barefootparadisevacations.com and http://barefootparadisevacations.com are being read as two different pages with the same page title. After the last crawl I used our built in redirect tool to redirect the urls, but the most recent crawl showed the same issue. Is this issue really hurting our rankings and if so, any suggestions on a fix for the problem? Thank you!

Duplicate Page Content and Titles
A few weeks ago my error count went up for Duplicate Page Content and Titles. 4 errors in all. A week later the errors were gone... But now they are back. I made changes to the Webconfig over a month ago but nothing since. SEOmoz is telling me the duplicate content is this http://www.antiquebanknotes.com/ and http://www.antiquebanknotes.com Thanks for any advise! This is the relevant web.config. <rewrite><rules><rule name="CanonicalHostNameRule1"><match url="(.*)"><conditions><add input="{HTTP_HOST}" pattern="^www.antiquebanknotes.com$" negate="true"></add></conditions>
