URL paramters and duplicate content
-
Hello,
I have a 2-fold question:
- Crawl Diagnostics is picking up a lot of Duplicate Page Title errors, and as far as I can tell, all of them are cause by URL parameters trailing the URL.
We use a Magento store, and all filtering attributes, categories, product pages etc are tagged on as URL parameters.
example:
Main URL:
/accessories.htmlDuplicated Title Page URLs:
/accessories.html?dir=asc&order=position
/accessories.html?mode=list
/accessories.html?mode=grid
...and many othersHow can I make the Crawl Diagnostics not identify these as errors?
- Now from an SEO point of view, all these URL parameters are been picked up by google, and are listed in WedMaster Tools -> URL parameters.
All URL parameters are set to "let google decide".
I remember having read that Google was smart enough here to make the right decision, and we shouldn't have to worry about it.
Is this true, or is there a larger issue at hand here?
Thankas!

I'm going to look into our canonical tags first - I think this is the best place to start.
Once this is done, I'll wait a week and see if the next scan yields fewer errors.
I'll keep you posted. Thanks.

Hi yacpro13. We had a similar problem. We aren't on Magento, but definitely we had the same issue. For us it was a combination of several things. Make sure that your canonical tags are squared away In our case, we had a program running that was automatically writing canonical tags that matched these URLs with the URL parameters attached. Eventually we stopped using the parameters completely, but by then many of these pages had already been indexed (even though they weren't technically separate pages, Google saw them as such). No, Google definitely wasn't smart enough to decide. In our case, Google had sometimes indexed 4-5 versions of the same identical page, and of course we were getting dinged for having duplicate content.
Because we aren't using the parameters any more our solution was to ask Google to remove those URLs from the index. This is a painfully long process for a big site. We've already submitted over 500 remove requests and only about 1/2 have been completed. In your case, since it appears you are currently using parameters, this may not be the best solution. I would start with the canonical tags and investigate those and make sure they aren't part of the problem.
Good luck. Hope this helps a tiny bit.

Moz crawl duplicate pages issues
Hi According to the moz crawl on my website I have in the region of 800 pages which are considered internal duplicates. I'm a little puzzled by this, even more so as some of the pages it lists as being duplicate of another are not. For example, the moz crawler considers page B to be a duplicate of page A in the urls below: Not sure on the live link policy so ive put a space in the urls to 'unlive' them. Page A http:// nuchic.co.uk/index.php/jeans/straight-jeans.html?manufacturer=3751 Page B http:// nuchic.co.uk/index.php/catalog/category/view/s/accessories/id/92/?cat=97&manufacturer=3603 One is a filter page for Curvety Jeans and the other a filter page for Charles Clinkard Accessories. The page titles are different, the page content is different so Ive no idea why these would be considered duplicate. Thin maybe, but not duplicate. Like wise, pages B and C are considered a duplicate of page A in the following Page A http:// nuchic.co.uk/index.php/bags.html?dir=desc&manufacturer=4050&order=price Page B http:// nuchic.co.uk/index.php/catalog/category/view/s/purses/id/98/?manufacturer=4001 Page C http:// nuchic.co.uk/index.php/coats/waistcoats.html?manufacturer=4053 Again, these are product filter pages which the crawler would have found using the site filtering system, but, again, I cannot find what makes pages B and C a duplicate of A. Page A is a filtered result for Great Plains Bags (filtered from the general bags collection). Page B is the filtered results for Chic Look Purses from the Purses section and Page C is the filtered results for Apricot Waistcoats from the Waistcoat section. I'm keen to fix the duplicate content errors on the site before it goes properly live at the end of this month - that's why anyone kind enough to check the links will see a few design issues with the site - however in order to fix the problem I first need to work out what it is and I can't in this case. Can anyone else see how these pages could be considered a duplicate of each other please? Checking ive not gone mad!! Thanks, Carl

Joomla Opencart Duplicate Link Issue
With a few recent catalog changes my client is having tons of duplicate content issues. The most peculiar is one that I cannot see visibly on the site pages. This page: http://www.CLIENTDOMAIN.com/catalog/lights.html shows to have several duplicate content issues with URLs such as: http://www.CLIENTDOMAIN.com/catalog/lights/Lamp-DRW.htmlhttp:/www.CLIENTDOMAIN.com - where the domain is basically added to the end of the first URL. Has anyone seen this? Any fixes, plugins or thoughts? Thanks,

Advice for 4000+ duplicate errors on 1st check
Hi, 1st time use of the SEOMOZ scan has thrown up a lot of duplicate errors. Seems to look like my site has a .com.au/ & .com.au/default for the same pages. We had the domain on a hosted cms solution & have now migrated to magento. We duplicated the pages, but had to redirect all of the old url's to he new magento structure. This was done via a developer adding a 301 wildcard code to the .htaccess. Would that many errors be normal for a 1st scan? Where should I look for someone to fix them? Thanks

Crawl Diagnostics Warnings - Duplicate Content
Hi All, I am getting a lot of warnings about duplicate page content. The pages are normally 'tag' pages. I have some news stories or blog posts tagged with multiple 'tags'. Should I ask google not to index the tag pages? Does it really affect my site? Thanks

Duplicate pages with canonical links still show as errors
On our CMS, there are duplicate pages such as /news, /news/, /news?page=1, /news/?page=1. From an SEO perspective, I'm not too worried, because I guess Google is pretty capable of sorting this out, but to be on the safe side, I've added canonical links. /news itself has no link, but all the other variants have links to "/news". (And if you go wild and add a bunch of random meaningless parameters, creating /news/?page=1&jim=jam&foo=bar&this=that, we will laugh at you and generate a canonical link back to "/news". We're clever like that.) So far so good. And everything appears to work fine. But SEOMoz is still flagging up errors about duplicate titles and duplicate content. If you click in, you'll see a "Note" on each error, showing that SEOMoz has found the canonical link. So SEOMoz knows the duplication isn't a problem, as we're using canonical links exactly the way they're supposed to be used, and yet is still flagging it as an error. Is this something I should be concerned about, or is it just a bug in SEOMoz?

How to get past PA and DA value for a specific URL ?
Hi everyone, I was wondering if there is a way to get the past PA and DA value for a specific URL ? I did run a small SEO campaign targeting a couple of deep pages over a month on my site and I would like to measure the efficiency of this campaign but I forgot to write down what was the PA (I know more aloess the DA) of those pages before the starting the campaign. Is their a way to retrieve the historical data of PA/DA ? thanks

Duplicate page titles are the same URL listed twice
The system says I have two duplicate page titles. The page titles are exactly the same because the two URLs are exactly the same. These same two identical URLs show up in the Duplicate Page Content also - because they are the same. We also have a blog and there are two tag pags showing identical content - I have blocked the blog in robots.txt now, because the blog is only for writers. I suppose I could have just blocked the tags pages.
