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

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

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

Duplicate content on URL trailing slash
Hello, Some time ago, we accidentally made changes to our site which modified the way urls in links are generated. At once, trailing slashes were added to many urls (only in links). Links that used to send to
Intermediate & Advanced SEO | | yacpro13
example.com/webpage.html Were now linking to
example.com/webpage.html/ Urls in the xml sitemap remained unchanged (no trailing slash). We started noticing duplicate content (because our site renders the same page with or without the trailing shash). We corrected the problematic php url function so that now, all links on the site link to a url without trailing slash. However, Google had time to index these pages. Is implementing 301 redirects required in this case?1 -
Duplicate content due to parked domains
I have a main ecommerce website with unique content and decent back links. I had few domains parked on the main website as well specific product pages. These domains had some type in traffic. Some where exact product names. So main main website www.maindomain.com had domain1.com , domain2.com parked on it. Also had domian3.com parked on www.maindomain.com/product1. This caused lot of duplicate content issues. 12 months back, all the parked domains were changed to 301 redirects. I also added all the domains to google webmaster tools. Then removed main directory from google index. Now realize few of the additional domains are indexed and causing duplicate content. My question is what other steps can I take to avoid the duplicate content for my my website 1. Provide change of address in Google search console. Is there any downside in providing change of address pointing to a website? Also domains pointing to a specific url , cannot provide change of address 2. Provide a remove page from google index request in Google search console. It is temporary and last 6 months. Even if the pages are removed from Google index, would google still see them duplicates? 3. Ask google to fetch each url under other domains and submit to google index. This would hopefully remove the urls under domain1.com and doamin2.com eventually due to 301 redirects. 4. Add canonical urls for all pages in the main site. so google will eventually remove content from doman1 and domain2.com due to canonical links. This wil take time for google to update their index 5. Point these domains elsewhere to remove duplicate contents eventually. But it will take time for google to update their index with new non duplicate content. Which of these options are best best to my issue and which ones are potentially dangerous? I would rather not to point these domains elsewhere. Any feedback would be greatly appreciated.

[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

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 -
Is an RSS feed considered duplicate content?
I have a large client with satellite sites. The large site produces many news articles and they want to put an RSS feed on the satellite sites that will display the articles from the large site. My question is, will the rss feeds on the satellite sites be considered duplicate content? If yes, do you have a suggestion to utilize the data from the large site without being penalized? If no, do you have suggestions on what tags should be used on the satellite pages? EX: wrapped in tags? THANKS for the help. Darlene

Duplicate Content on Wordpress b/c of Pagination
On my recent crawl, there were a great many duplicate content penalties. The site is http://dailyfantasybaseball.org. The issue is: There's only one post per page. Therefore, because of wordpress's (or genesis's) pagination, a page gets created for every post, thereby leaving basically every piece of content i write as a duplicate. I feel like the engines should be smart enough to figure out what's going on, but if not, I will get hammered. What should I do moving forward? Thanks!
