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.

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

International SEO - cannibalisation and duplicate content
Hello all, I look after (in house) 3 domains for one niche travel business across three TLDs: .com .com.au and co.uk and a fourth domain on a co.nz TLD which was recently removed from Googles index. Symptoms: For the past 12 months we have been experiencing canibalisation in the SERPs (namely .com.au being rendered in .com) and Panda related ranking devaluations between our .com site and com.au site. Around 12 months ago the .com TLD was hit hard (80% drop in target KWs) by Panda (probably) and we began to action the below changes. Around 6 weeks ago our .com TLD saw big overnight increases in rankings (to date a 70% averaged increase). However, almost to the same percentage we saw in the .com TLD we suffered significant drops in our .com.au rankings. Basically Google seemed to switch its attention from .com TLD to the .com.au TLD. Note: Each TLD is over 6 years old, we've never proactively gone after links (Penguin) and have always aimed for quality in an often spammy industry. **Have done: ** Adding HREF LANG markup to all pages on all domain Each TLD uses local vernacular e.g for the .com site is American Each TLD has pricing in the regional currency Each TLD has details of the respective local offices, the copy references the lacation, we have significant press coverage in each country like The Guardian for our .co.uk site and Sydney Morning Herlad for our Australia site Targeting each site to its respective market in WMT Each TLDs core-pages (within 3 clicks of the primary nav) are 100% unique We're continuing to re-write and publish unique content to each TLD on a weekly basis As the .co.nz site drove such little traffic re-wrting we added no-idex and the TLD has almost compelte dissapread (16% of pages remain) from the SERPs. XML sitemaps Google + profile for each TLD **Have not done: ** Hosted each TLD on a local server Around 600 pages per TLD are duplicated across all TLDs (roughly 50% of all content). These are way down the IA but still duplicated. Images/video sources from local servers Added address and contact details using SCHEMA markup Any help, advice or just validation on this subject would be appreciated! Kian

How do I geo-target continents & avoid duplicate content?
Hi everyone, We have a website which will have content tailored for a few locations: USA: www.site.com
Intermediate & Advanced SEO | | AxialDev
Europe EN: www.site.com/eu
Canada FR: www.site.com/fr-ca Link hreflang and the GWT option are designed for countries. I expect a fair amount of duplicate content; the only differences will be in product selection and prices. What are my options to tell Google that it should serve www.site.com/eu in Europe instead of www.site.com? We are not targeting a particular country on that continent. Thanks!0 -
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.

Capitals in url creates duplicate content?
Hey Guys, I had a quick look around however I couldn't find a specific answer to this. Currently, the SEOmoz tools come back and show a heap of duplicate content on my site. And there's a fair bit of it. However, a heap of those errors are relating to random capitals in the urls. for example. "www.website.com.au/Home/information/Stuff" is being treated as duplicate content of "www.website.com.au/home/information/stuff" (Note the difference in capitals). Anyone have any recommendations as to how to fix this server side(keeping in mind it's not practical or possible to fix all of these links) or to tell Google to ignore the capitalisation? Any help is greatly appreciated. LM.

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?
