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

How can I avoid duplicate content for a new landing page which is the same as an old one?
Hello mozers! I have a question about duplicate content for you... One on my clients pages have been dropping in search volume for a while now, and I've discovered it's because the search term isn't as popular as it used to be. So... we need to create a new landing page using a more popular search term. The page which is losing traffic is based on the search query "Can I put a solid roof on my conservatory" this only gets 0-10 searches per month according to the keyword explorer tool. However, if we changed this to "replacing conservatory roof with solid roof" this gets up to 500 searches per month. Muuuuch better! The issue is, I don't want to close down and re-direct the old page because it's got a featured snippet and sits in position 1. So I'd like to create another page instead... however, as the two are effectively the same content, I would then land myself in a duplicate content issue. If I were to put a rel="canonical" tag in the original "can I put a solid roof...." page but say the master page is now the new one, would that get around the issue?

Does Google ignore content styled with 'display:none'?
Do you know if an H1 within a div that has a 'display: none' style applied will still be crawled and evaluated by Google? We have that situation on this page on line 136: view-source:https://www.junk-king.com/services/items-we-take/foreclosure-cleanouts Of course we also have an H1 up at the top of the page and are concerned that the second one will cause interference with our SEO efforts. I've seen conflicting and inconclusive information on line - not sure. Thanks for any help.

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,

Same product in different categories and duplicate content issues
Hi,I have some questions related to duplicate content on e-commerce websites. 1)If a single product goes to multiple categories (eg. A black elegant dress could be listed in two categories like "black dresses" and "elegant dresses") is it considered duplicate content even if the product url is unique? e.g www.website.com/black-dresses/black-elegant-dress duplicated> same content from two different paths www.website.com/elegant-dresses/black-elegant-dress duplicated> same content from two different paths www.website.com/black-elegant-dress unique url > this is the way my products urls look like Does google perceive this as duplicated content? The path to the content is only one, so it shouldn't be seen as duplicated content, though the product is repeated in different categories.This is the most important concern I actually have. It is a small thing but if I set this wrong all website would be affected and thus penalised, so I need to know how I can handle it. 2- I am using wordpress + woocommerce. The website is built with categories and subcategories. When I create a product in the product page backend is it advisable to select just the lowest subcategory or is it better to select both main category and subcategory in which the product belongs? I usually select the subcategory alone. Looking forward to your reply and suggestions. 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.

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

Is SEOmoz.org creating duplicate content with their CDN subdomain?
Example URL: http://cdn.seomoz.org/q/help-with-getting-no-conversions Canonical is a RELATIVE link, should be an absolute link pointing to main domain: http://www.seomoz.org/q/help-with-getting-no-conversions <link href='[/q/help-with-getting-no-conversions](view-source:http://cdn.seomoz.org/q/help-with-getting-no-conversions)' rel='<a class="attribute-value">canonical</a>' /> 13,400 pages indexed in Google under cdn subdomain go to google > site:http://cdn.seomoz.org https://www.google.com/#hl=en&output=search&sclient=psy-ab&q=site:http%3A%2F%2Fcdn.seomoz.org%2F&oq=site:http%3A%2F%2Fcdn.seomoz.org%2F&gs_l=hp.2...986.6227.0.6258.28.14.0.0.0.5.344.3526.2-10j2.12.0.les%3B..0.0...1c.Uprw7ko7jnU&pbx=1&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.&fp=97577626a0fb6a97&biw=1920&bih=936

Duplicate Content | eBay
My client is generating templates for his eBay template based on content he has on his eCommerce platform. I'm 100% sure this will cause duplicate content issues. My question is this.. and I'm not sure where eBay policy stands with this but adding the canonical tag to the template.. will this work if it's coming from a different page i.e. eBay? Update: I'm not finding any information regarding this on the eBay policy's: http://ocs.ebay.com/ws/eBayISAPI.dll?CustomerSupport&action=0&searchstring=canonical So it does look like I can have rel="canonical" tag in custom eBay templates but I'm concern this can be considered: "cheating" since rel="canonical is actually a 301 but as this says: http://googlewebmastercentral.blogspot.com/2009/12/handling-legitimate-cross-domain.html it's legitimately duplicate content. The question is now: should I add it or not? UPDATE seems eBay templates are embedded in a iframe but the snap shot on google actually shows the template. This makes me wonder how they are handling iframes now. looking at http://www.webmaster-toolkit.com/search-engine-simulator.shtml does shows the content inside the iframe. Interesting. Anyone else have feedback?
