Duplicate Content through 'Gclid'
-
Hello,
We've had the known problem of duplicate content through the gclid parameter caused by Google Adwords. As per Google's recommendation - we added the canonical tag to every page on our site so when the bot came to each page they would go 'Ah-ha, this is the original page'. We also added the paramter to the URL parameters in Google Wemaster Tools.
However, now it seems as though a canonical is automatically been given to these newly created gclid pages; below
Therefore these new pages are now being indexed, causing duplicate content. Does anyone have any idea about what to do in this situation?
Thanks,
Stephen.

Gentlemen, thank you for taking the time to contribute.
If Google doesn't crawl and index, can you guys explain this?
I have found the solution elsewhere. The canonical tag is auto-generated, so it is creating it's own canonical tag for the pages. So we need to create a rule in the back end that exlcudes parameters after the end of our URL's

I completely agree with the above answer, the links with GCLID are generated through Google Adwords and so on they won't be available to Googlebot when crawling the site. Also if it even would happen you could let Google ignore that parameter, but as it's one of Googles own parameters I doubt it would ever get you in trouble.

Hi Stephen,
GoogleBot can't crawl links with a gclid, so they won't end up in the index and won't be flagged as duplicate pages.
AdWords does not work this way. The script that produces the ads contains no links--there's nothing for GoogleBot to discover without running the script. which it does not do. I am not certain that Google search produces the ads the same way, but what would be the point of GoogleBot crawling Google SERPs? It doesn't do that.
I do include canonical tag in the header of all our pages, which is one of Google's suggestions for dealing with this. I suppose that could be why I don't have an issue with this.
*If you don't believe this to be true, look through your logs and try to find one record of GoogleBot crawling an AdWords link with a valid gclid.
Hope this helps.
Thanks

Upper and lower case URLS coming up as duplicate content
Hey guys and gals, I'm having a frustrating time with an issue. Our site has around 10 pages that are coming up as duplicate content/ duplicate title. I'm not sure what I can do to fix this. I was going to attempt to 301 direct the upper case to lower but I'm worried how this will affect our SEO. can anyone offer some insight on what I should be doing? Update: What I'm trying to figure out is what I should do for our URL's. For example, when I run an audit I'm getting two different pages: aaa.com/BusinessAgreement.com and also aaa.com/businessagreement.com. We don't have two pages but for some reason, Google thinks we do.

Same site serving multiple countries and duplicated content
Hello! Though I browse MoZ resources every day, I've decided to directly ask you a question despite the numerous questions (and answers!) about this topic as there are few specific variants each time: I've a site serving content (and products) to different countries built using subfolders (1 subfolder per country). Basically, it looks like this:
Intermediate & Advanced SEO | | GhillC
site.com/us/
site.com/gb/
site.com/fr/
site.com/it/
etc. The first problem was fairly easy to solve:
Avoid duplicated content issues across the board considering that both the ecommerce part of the site and the blog bit are being replicated for each subfolders in their own language. Correct me if I'm wrong but using our copywriters to translate the content and adding the right hreflang tags should do. But then comes the second problem: how to deal with duplicated content when it's written in the same language? E.g. /us/, /gb/, /au/ and so on.
Given the following requirements/constraints, I can't see any positive resolution to this issue:
1. Need for such structure to be maintained (it's not possible to consolidate same language within one single subfolders for example),
2. Articles from one subfolder to another can't be canonicalized as it would mess up with our internal tracking tools,
3. The amount of content being published prevents us to get bespoke content for each region of the world with the same spoken language. Given those constraints, I can't see a way to solve that out and it seems that I'm cursed to live with those duplicated content red flags right up my nose.
Am I right or can you think about anything to sort that out? Many thanks,

How will changing my website's page content affect SEO?
Our company is looking to update the content on our existing web pages and I am curious what the best way to roll out these changes are in order to maintain good SEO rankings for certain pages. The infrastructure of the site will not be modified except for maybe adding a couple new pages, but existing domains will stay the same. If the domains are staying the same does it really matter if I just updated 1 page every week or so, versus updating them all at once? Just looking for some insight into how freshening up the content on the back end pages could potentially hurt SEO rankings initially. Thanks!

Duplicate content on recruitment website
Hi everyone, It seems that Panda 4.2 has hit some industries more than others. I just started working on a website, that has no manual action, but the organic traffic has dropped massively in the last few months. Their external linking profile seems to be fine, but I suspect usability issues, especially the duplication may be the reason. The website is a recruitment website in a specific industry only. However, they posts jobs for their clients, that can be very similar, and in the same time they can have 20 jobs with the same title and very similar job descriptions. The website currently have over 200 pages with potential duplicate content. Additionally, these jobs get posted on job portals, with the same content (Happens automatically through a feed). The questions here are: How bad would this be for the website usability, and would it be the reason the traffic went down? Is this the affect of Panda 4.2 that is still rolling What can be done to resolve these issues? Thank you in advance.

Removing duplicate content
Due to URL changes and parameters on our ecommerce sites, we have a massive amount of duplicate pages indexed by google, sometimes up to 5 duplicate pages with different URLs. 1. We've instituted canonical tags site wide. 2. We are using the parameters function in Webmaster Tools. 3. We are using 301 redirects on all of the obsolete URLs 4. I have had many of the pages fetched so that Google can see and index the 301s and canonicals. 5. I created HTML sitemaps with the duplicate URLs, and had Google fetch and index the sitemap so that the dupes would get crawled and deindexed. None of these seems to be terribly effective. Google is indexing pages with parameters in spite of the parameter (clicksource) being called out in GWT. Pages with obsolete URLs are indexed in spite of them having 301 redirects. Google also appears to be ignoring many of our canonical tags as well, despite the pages being identical. Any ideas on how to clean up the mess?

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! Dave

Concerns about duplicate content issues with australian and us version of website
My company has an ecommerce website that's been online for about 5 years. The url is www.betterbraces.com. We're getting ready to launch an australian version of the website and the url will be www.betterbraces.com.au. The australian website will have the same look as the US website and will contain about 200 of the same products that are featured on the US website. The only major difference between the two websites is the price that is charged for the products. The australian website will be hosted on the same server as the US website. To ensure Australians don't purchase from the US site we are going to have a geo redirect in place that sends anyone with a AU ip address to the australian website. I am concerned that the australian website is going to have duplicate content issues. However, I'm not sure if the fact that the domains are so similar coupled with the redirect will help the search engines understand that these sites are related. I would appreciate any recommendations on how to handle this situation to ensure oue rankings in the search engines aren't penalized. Thanks in advance for your help. Alison French
