Diagnosing duplicate content issues
-
We recently made some updates to our site, one of which involved launching a bunch of new pages. Shortly afterwards we saw a significant drop in organic traffic. Some of the new pages list similar content as previously existed on our site, but in different orders. So our question is, what's the best way to diagnose whether this was the cause of our ranking drop? My current thought is to block the new directories via robots.txt for a couple days and see if traffic improves. Is this a good approach? Any other suggestions?

I hate to advocate full-scale blocking, but if you really took a hit, and you know the timeline coincided with the new content, it is possible. It might be better to scale back and re-roll out new content in chunks.
One warning - if this is a regular filter (you added a bunch of duplicates), Google should start re-ranking content as soon as the blocking kicks in (this may take weeks, not days). If this was Panda-related or more severe, though, it could take a month or more to see an impact. Not to be the bearer of bad news, but don't Robots.txt block the pages for 2 days, decide it didn't work, and unblock them.
A slightly less extreme approach would be to META NOINDEX all of the pages. That way, you could start to selectively lift the NOINDEX on content piece by piece. If you Robots.txt block all the new directories, it's going to be hard to re-introduce the content. You'll end up releasing the block all at once and potentially just having the same problem again.

Could always give it a whirl...

yeah, unfortunately we've checked all the items you listed and there's nothing obvious. seems like blocking pages is the only option left..
-
Here's what I'd do.
First, check big stuff like:
- Did your URLs change? Is so, were redirects applied?
- Did your devs accidentally noindex or nofollow entire sections of the site? I've seen this happen a bunch.
If neither of the above, I'd next dig deep with analytics to try to figure out if there is a certain pages, type of pages (product page, articles, blog, etc), etc. that have taken the biggest hit.It may give you more direction. Could also:
- Review Webmaster tools
- Run a site scanner link ScreamingFrog and look for big errors
You could always try blocking new stuff but you never know how long it's gonna take google to come back and honor your changes.

Are feeds bad for duplicate content?
One of my clients has been invited to feature his blog posts here https://app.mindsettlers.com/. Here is an example of what his author page would look like: https://app.mindsettlers.com/author/6rs0WXbbqwqsgEO0sWuIQU. I like that he would get the exposure however I am concerned about duplicate content with the feed. If he has a canonical tag on each blog post to itself, would that be sufficient for the search engines? Is there something else that could be done? Or should he decline? Would love your thoughts! Thanks.

Fix Duplicate Content Before Migration?
My client has 2 Wordpress sites (A and B). Each site is 20 pages, with similar site structures, and 12 of the pages on A having nearly 100% duplicate content with their counterpart on B. I am not sure to what extent A and/or B is being penalized for this. In 2 weeks (July 1) the client will execute a rebrand, renaming the business, launching C, and taking down A and B. Individual pages on A and B will be 301 redirected to their counterpart on C. C will have a similar site structure to A and B. I expect the content will be freshened a bit, but may initially be very similar to the content on A and B. I have 3 questions: Given that only 2 weeks remain before the switchover - is there any purpose in resolving the duplicate content between A and B prior to taking them down? Will 301 redirects from penalized pages on A or B actually hurt the ranking of the destination page on C? If a page on C has the same content as its predecessor on A or B, could it be penalized for that, even though the page on A or B has since been taken down and replaced with a 301 redirect?

Duplicate content across different domains
Hi Guys, Looking for some advice regarding duplicate content across different domains. I have reviewed some previous Q&A on this topic e.g. https://moz.com/community/q/two-different-domains-exact-same-content but just want to confirm if I'm missing anything. Basically, we have a client which has 1 site (call this site A) which has solids rankings. They have decided to build a new site (site B), which contains 50% duplicate pages and content from site A. Our recommendation to them was to make the content on site B as unique as possible but they want to launch asap, so not enough time. They will eventually transfer over to unique content on the website but in the short-term, it will be duplicate content. John Mueller from Google has said several times that there is no duplicate content penalty. So assuming this is correct site A should be fine, no ranking losses. Any disagree with this? Assuming we don't want to leave this to chance or assume John Mueller is correct would the next best thing to do is setup rel canonical tags between site A and site B on the pages with duplicate content? Then once we have unique content ready, execute that content on the site and remove the canonical tags. Any suggestions or advice would be very much appreciated! Cheers, Chris

Duplicate Content Errors new website. How do you know which page to put the rel canonical tag on?
I am having problems with duplicate content. This is a new website and all the pages have the same page and domain rank, the following is an example of the homepage. How do you know which page to use the canonical tag on? http://medresourcesupply.com/index.php http://medresourcesupply.com/ Would this be the correct way to use this? Here is another example where Moz says these are duplicates. I can't figure out why because they have different url's and content. http://medresourcesupply.com/clutching_at_the_throat http://medresourcesupply.com/index.php?src=gendocs&ref=detailed_specfications &category=Main

Semi-duplicate content yet authoritative site
So I have 5 real estate sites. One of those sites is of course the original, and it has more/better content on most of the pages than the other sites. I used to be top ranked for all of the subdivsion names in my town. Then when I did the next 2-4 sites, I had some sites doing better than others for certain keywords, and then I have 3 of those sites that are basically the same URL structures (besides the actual domain) and they aren't getting fed very many visits. I have a couple of agents that work with me that I loaned my sites to to see if that would help since it would be a different name. My same youtube video is on each of the respective subdivision pages of my site and theirs. Also, their content is just rewritten content from mine about the same length of content. I have looked over and seen a few of my competitors who only have one site and their URL structures arent good at all, and their content isn't good at all and a good bit of their pages rank higher than my main site which is very frustrating to say the least since they are actually copy cats to my site. I sort of started the precedent of content, mapping the neighborhood, how far that subdivision is from certain landmarks, and then shot a video of each. They have pretty much done the same thing and are now ahead of me. What sort of advice could you give me? Right now, I have two sites that are almost duplicate in terms of a template and same subdivsions although I did change the content the best I could, and that site is still getting pretty good visits. I originally did it to try and dominate the first page of the SERPS and then Penguin and Panda came out and seemed to figure that game out. So now, I would still like to keep all the sites, but I'm assuming that would entail making them all unique, which seems to be tough seeing as though my town has the same subdivisions. Curious as to what the suggestions would be, as I have put a lot of time into these sites. If I post my site will it show up in the SERPS? Thanks in advance

Duplicate Page Content - Shopify
Moz reports that there are 1,600+ pages on my site (Sportiqe.com) that qualify as Duplicate Page Content. The website sells licensed apparel, causing shirts to go into multiple categories (ie - LA Lakers shirts would be categorized in three areas: Men's Shirts, LA Lakers Shirts and NBA Shirts)It looks like "tags" are the primary cause behind the duplicate content issues: // Collection Tags_Example: : http://www.sportiqe.com/collections/la-clippers-shirts (Preferred URL): http://www.sportiqe.com/collections/la-clippers-shirts/la-clippers (URL w/ tag): http://sportiqe.com/collections/la-clippers-shirts/la-clippers (URL w/ tag, w/o the www.): http://sportiqe.com/collections/all-products/clippers (Different collection, w/ tag and same content)// Blog Tags_Example: : http://www.sportiqe.com/blogs/sportiqe/7902801-dispatch-is-back: http://www.sportiqe.com/blogs/sportiqe/tagged/elias-fundWould it make sense to do 301 redirects for the collection tags and use the Parameter Tool in Webmaster Tools to exclude blog post tags from their crawl? Or, is there a possible solution with the rel=cannonical tag?Appreciate any insight from fellow Shopify users and the Moz community.

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.

Avoiding duplicate content on an ecommerce site
Hi all, I have an ecommerce site which has a standard block of text on 98% of the product pages. The site also has a blog. Because these cause duplicate content and duplicate title issues respectively, how can I ever get around this? Would having the standard text on the product pages displayed as an image help? And how can I stop the blog being listed as duplicate titles without a nofollow? We already have the canonical attribute applied to some areas where this is appropriate e.g. blog and product categories. Thanks for your help 🙂
