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

Duplicate content in Shopify - subsequent pages in collections
Hello everyone! I hope an expert in this community can help me verify the canonical codes I'll add to our store is correct. Currently, in our Shopify store, the subsequent pages in the collections are not indexed by Google, however the canonical URL on these pages aren't pointing to the main collection page (page 1), e.g. The canonical URL of page 2, page 3 etc are used as canonical URLs instead of the first page of the collections. I have the canonical codes attached below, it would be much appreciated if an expert can urgently verify these codes are good to use and will solve the above issues? Thanks so much for your kind help in advance!! -----------------CODES BELOW--------------- <title><br /> {{ page_title }}{% if current_tags %} – tagged "{{ current_tags | join: ', ' }}"{% endif %}{% if current_page != 1 %} – Page {{ current_page }}{% endif %}{% unless page_title contains shop.name %} – {{ shop.name }}{% endunless %}<br /></title>

Trailing Slashes for Magento CMS pages - 2 URLS - Duplicate content
Hello, Can anyone help me find a solution to Fixing and Creating Magento CMS pages to only use one URL and not two URLS? www.domain.com/testpage www.domain.com/testpage/ I found a previous article that applies to my issue, which is using htaccess to redirect request for pages in magento 301 redirect to slash URL from the non-slash URL. I dont understand the syntax fully in htaccess , but I used this code below. This code below fixed the CMS page redirection but caused issues on other pages, like all my categories and products with this error: "This webpage has a redirect loop ERR_TOO_MANY_REDIRECTS" Assuming you're running at domain root. Change to working directory if needed. RewriteBase / # www check If you're running in a subdirectory, then you'll need to add that in to the redirected url (http://www.mydomain.com/subdirectory/$1 RewriteCond %{HTTP_HOST} !^www. [NC]

[E-commerce] Duplicate content due to color variations (canonical/indexing)
Hello, We currently have a lot of color variations on multiple products with almost the same content. Even with our canonicals being set, Moz's crawling tool seems to flag them as duplicate content. What we have done so far: Choosing the best-selling color variation (our "master product") Adding a rel="canonical" to every variation (with our "master product" as the canonical URL) In my opinion, it should be enough to address this issue. However, being given the fact that it's flagged as duplicate by Moz, I was wondering if there is something else we should do? Should we add a "noindex,follow" to our child products and "index,follow" to our master product? (sounds to me like such a heavy change) Thank you in advance

PDF for link building - avoiding duplicate content
Hello, We've got an article that we're turning into a PDF. Both the article and the PDF will be on our site. This PDF is a good, thorough piece of content on how to choose a product. We're going to strip out all of the links to our in the article and create this PDF so that it will be good for people to reference and even print. Then we're going to do link building through outreach since people will find the article and PDF useful. My question is, how do I use rel="canonical" to make sure that the article and PDF aren't duplicate content? Thanks.
