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

SEM Rush & Duplicate content
Hi SEMRush is flagging these pages as having duplicate content, but we have rel = next etc implemented: https://www.key.co.uk/en/key/brand/bott https://www.key.co.uk/en/key/brand/bott?page=2 Or is it being flagged as they're just really similar pages?

Does content revealed by a 'show more' button get crawled by Google?
I have a div on my website with around 500 words of unique content in, automatically when the page is first visited the div has a fixed height of 100px, showing a couple of hundred words and fading out to white, with a show more button, which when clicked, increases the height to show the full content. My question is, does Google crawl the content in that div when it renders the page? Or disregard it? Its all in the source code. Or worse, do they consider this cloaking or hidden content? It is only there to make the site more useable for customers, so i don't want to get penalised for it. Cheers

Woocommerce SEO & Duplicate content?
Hi Moz fellows, I'm new to Woocommerce and couldn't find help on Google about certain SEO-related things. All my past projects were simple 5 pages websites + a blog, so I would just no-index categories, tags and archives to eliminate duplicate content errors. But with Woocommerce Product categories and tags, I've noticed that many e-Commerce websites with a high domain authority actually rank for certain keywords just by having their category/tags indexed. For example keyword 'hippie clothes' = etsy.com/category/hippie-clothes (fictional example) The problem is that if I have 100 products and 10 categories & tags on my site it creates THOUSANDS of duplicate content errors, but If I 'non index' categories and tags they will never rank well once my domain authority rises... Anyone has experience/comments about this? I use SEO by Yoast plugin. Your help is greatly appreciated! Thank you in advance. -Marc

Duplicate Content www vs. non-www and best practices
I have a customer who had prior help on his website and I noticed a 301 redirect in his .htaccess Rule for duplicate content removal : www.domain.com vs domain.com RewriteCond %{HTTP_HOST} ^MY-CUSTOMER-SITE.com [NC]
Intermediate & Advanced SEO | | EnvoyWeb
RewriteRule (.*) http://www.MY-CUSTOMER-SITE.com/$1 [R=301,L,NC] The result of this rule is that i type MY-CUSTOMER-SITE.com in the browser and it redirects to www.MY-CUSTOMER-SITE.com I wonder if this is causing issues in SERPS. If I have some inbound links pointing to www.MY-CUSTOMER-SITE.com and some pointing to MY-CUSTOMER-SITE.com, I would think that this rewrite isn't necessary as it would seem that Googlebot is smart enough to know that these aren't two sites. -----Can you comment on whether this is a best practice for all domains?
-----I've run a report for backlinks. If my thought is true that there are some pointing to www.www.MY-CUSTOMER-SITE.com and some to the www.MY-CUSTOMER-SITE.com, is there any value in addressing this?0 -
Duplicate content on sites from different countries
Hi, we have a client who currently has a lot of duplicate content with their UK and US website. Both websites are geographically targeted (via google webmaster tools) to their specific location and have the appropriate local domain extension. Is having duplicate content a major issue, since they are in two different countries and geographic regions of the world? Any statement from Google about this? Regards, Bill

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.

Duplicate content on ecommerce sites
I just want to confirm something about duplicate content. On an eCommerce site, if the meta-titles, meta-descriptions and product descriptions are all unique, yet a big chunk at the bottom (featuring "why buy with us" etc) is copied across all product pages, would each page be penalised, or not indexed, for duplicate content? Does the whole page need to be a duplicate to be worried about this, or would this large chunk of text, bigger than the product description, have an effect on the page. If this would be a problem, what are some ways around it? Because the content is quite powerful, and is relavent to all products... Cheers,
