Database driven content producing false duplicate content errors
-
How do I stop the Moz crawler from creating false duplicate content errors. I have yet to submit my website to google crawler because I am waiting to fix all my site optimization issues.
Example: contactus.aspx?propid=200, contactus.aspx?propid=201.... these are the same pages but with some old url parameters stuck on them. How do I get Moz and Google not to consider these duplicates. I have looked at http://moz.com/learn/seo/duplicate-content with respect to
Rel="canonical"
and I think I am just confused.

All of you guys rock! I have never been involved in a community that has had the right answers every time... I used the on all my static pages such as directions, policies, contact, etc... and it removed all the parameters thereby eliminating them from standing out in the MOZ crawl.. I feel like and idiot not knowing about this HTML tag and its importance. My moz crawl now looks so so much better.
When I mean old url parameters, I just meant a few seconds old, meaning the user is on property.aspx?property=1 then when they moved to a static page such as contact, directions, policy we now have another page called contact.aspx?property=1 which if I have 150 properties times 10 static pages I basically just created 150 duplicate content errors just for the contact page alone. Because contact.aspx?property=1 or contact.aspx?property=150 and in between are all the same page... I am sure this has killed my SEO. SO THAT PROBLEM IS NOW FIXED!!
NOW to revisit what zenstorageunits says about URL rewriting which has many different ways to do it using .net, but Miketek I would not have to create subdirectories because it is done in the code... they are more like virtual directories...
zenstorageunits or anyone else for that matter, Is it worth it for me to hire somebody to create a URL rewrite app that can change the following;
http:/www.destinationbigbear.com/property_detail.aspx?propid=202 to
http://www.destinationbigbear.com/big-bear-cabin-rentals/a-true-cabin/details
and
http:/www.destinationbigbear.com/property_photos.aspx?propid=202 to
http://www.destinationbigbear.com/big-bear-cabin-rentals/a-true-cabin/photos
See everyone of my 150 cabins has these pages; info, photos, calendar, video, reviews, rates...and they all have unique cabin names... so it is basically 150 cabins x 6 pages = 900 unique pages with unique content but really only 6 pages dynamically being changed by 150 cabins.
I have been able to dynamically change all the page titles for everyone of these 900 database driven pages such as
Big-Bear-Cabin | A True Cabin Photos or Big-Bear-Cabin | A True Cabin Calendar and so on.

Hi Nick,
I think you've gotten some good tips here - I'd agree with Prestashop that the preferred solution would be to find where these parameters are being included in links to this page and remove them.
Failing that, zenstorageunits's advice to use rel="canonical" would be my recommendation - or a 301 redirect from the URLs that include parameters back to the core URL would work.
I wouldn't convert these parameters to subdirectories unless they are integral to the way your site works and pull up unique content - you called them "old parameters" so it sounds like they're not supposed to be there, so probably not a case where you'd want to convert these parameters to subdirectories.
Failing the above, you could utilize the Google Webmaster Tools "URL Parameters" interface to tell Googlebot to ignore these parameters.
Overall, your best course of action is to find and remove the links that include the parameters.
I'd also add that the Moz crawl report is highly sensitive to "duplicate content," and I often find it flags up issues has high/medium priority that are not actually going to have a significant impact on the site. You have to take the crawl report with a grain of salt - while duplicate content can be a serious issue for some sites (ecommerce retailers for example with duplication issues across a wide catalog of products), in most cases it has minimal impact and isn't something I'd hold up your site launch for.
Best of Luck,

I agree zenstorageunits about using rel=canonical but one thing I would like to point out is that Moz does not create false errors. It is a simple crawler, not like google. Google will actually try to follow links that people have used before and that show up in your analytics files. moz uses no logic like that, it just jumps from page to page. If it is picking up a page with a query string like that then it is a link on your site. I would find the links and take them off.

You have a few options you could do. One thing I would look into is maybe doing some url rewriting to change
contactus.aspx?propid=200
to
contactus/propid/200
look at http://msdn.microsoft.com/en-us/library/ms972974.aspx on how to do that for IIS.
A better option I think if you need to keep the parameters the way they are is to use the rel canocial tag look at moz article
http://moz.com/blog/rel-confused-answers-to-your-rel-canonical-questions
but basicly you would need to add something like this to your contact.aspx page(replace example.com with your website url)
This suggest to the website crawler, like google or moz crawler, that those pages should be assoicated with the contact.aspx page.

Canonical Tags for Legacy Duplicate Content
I've got a lot of duplicate pages, especially products, and some are new but most have been like this for a long time; up to several years. Does it makes sense to use a canonical tag pointing to one master page for each product. Each page is slightly different with a different feature and includes maybe a sentence or two that is unique but everything else is the same.

Duplicate Page Content and Titles from Weebly Blog
Anyone familiar with Weebly that can offer some suggestions? I ran a crawl diagnostics on my site and have some high priority issues that appear to stem from Weebly Blog posts. There are several of them and it appears that the post is being counted as "page content" on the main blog feed and then again when it is tagged to a category. I hope this makes sense, I am new to SEO and this is really confusing. Thanks!

Fullsite=true coming up as duplicate content?
Hello, I am new to the fullsite=true method of mobile site to desktop site, and have recently found that about 50 of the instances in which I added fullsite=true to links from our blog show as a duplicate to the page that it is pointing to? Could someone tell me why this would be? Do I need to add some sort of rel=canonical to the main page (non-fullsite=true) or how should I approach this? Thanks in advance for your help! L

Hreflang and possible duplicate content SEO issue
| 0 <a class="vote-down-off" title="This question does not show any research effort; it is unclear or not useful">down vote</a> favorite | Hey community, my first question here 🙂 Imagine there is a page with video, it has hreflang tags setup, to lead let's say German visitors to /de/ folder... So, on that German version of page, everything like menus, navigation and such are in German, but the video is the same, the title of the video (H1 tag) is the same, <title></code></strong> and <strong><code>meta description</code></strong> is the same as on the original English page. It means that general (English) page and German version of it has the same key content in English.</p> <p>To me it seems to be a SEO duplicate content issue. As I know, Google doesn't think that content is duplicate, if it is properly translated to other language.</p> <p>Does my explained case mean that the content will be detected by Google as duplicate?</p> </div> </div> </td> </tr> </tbody> </table></title> |

Duplicate content due to credit card testing
I recently launched a site - http://www.footballtriviaquestions.co.uk and the site uses Paypal. In order to test the PayPal functionality I set up a zapto.org domain via a permanent IP service that points directly to the computer I've written the website on. It appears that Google has now indexed the zapto.org website. Will this cause problems to my main website, as the zapto.org website will pretty much contain content that is an exact duplicate of what is held on the main website. I've looked in Google webmaster tools for the main website and it doesn't mention any duplicate content, but I'm currently not in the top 50 ranking for "football trivia questions' on Google despite SEOMoz ranking my home page with an A rating. The page does rank at position 16 in Yahoo and Bing. This seems odd to me, although I do have very few back links pointing to my site. If the duplicate content is likely to be causing me problems what would be the best way to knock the zapto.org results out of Google

Error msg 'Duplicate Page Content', how to fix?
Hey guys, I'm new to SEO and have the following error msg 'Duplicate Page Content'. Of course I know what it means, but my question is how do you delete the old pages that has duplicate content? I use to run my website through Joomla! but have since moved to Shopify. I see that the duplicated site content is still from the old Joomla! site and I would like to learn how to delete this content (or best practice in this situation). Any advice would be very helpful! Cheers, Peter

Getting rid of duplicate content with rel=canonical
This may sound like a stupid question, however it's important that I get this 100% straight. A new client has nearly 6k duplicate page titles / descriptions. To cut a long story short, this is mostly the same page (or rather a set of pages), however every time Google visits these pages they get a different URL. Hence the astronomical number of duplicate page titles and descriptions. Now the easiest way to fix this looks like canonical linking. However, I want to be absolutely 100% sure that Google will then recognise that there is no duplicate content on the site. Ideally I'd like to 301 but the developers say this isn't possible, so I'm really hoping the canonical will do the job. Thanks.
