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.

Questions about Event Calendar Format and Duplicate Content
Hi there: We maintain a calendar of digital events and conferences on our website here: https://splatworld.tv/events/ . We're trying to add as many events as we can and I'm wondering about the descriptions of each. We're pulling them from the conference websites, mostly, but I'm worried about the scraped content creating duplicate content issues. I've also noticed that most calendars of this type which rank well are not including actual event descriptions, but rather just names, locations and a link out to the conference website. See https://www.semrush.com/blog/the-ultimate-calendar-of-digital-marketing-events-2017/ and http://www.marketingterms.com/conferences/ . Anyone have any thoughts on this? Thanks, in ..advance..

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 -
Removing duplicate content
Due to URL changes and parameters on our ecommerce sites, we have a massive amount of duplicate pages indexed by google, sometimes up to 5 duplicate pages with different URLs. 1. We've instituted canonical tags site wide. 2. We are using the parameters function in Webmaster Tools. 3. We are using 301 redirects on all of the obsolete URLs 4. I have had many of the pages fetched so that Google can see and index the 301s and canonicals. 5. I created HTML sitemaps with the duplicate URLs, and had Google fetch and index the sitemap so that the dupes would get crawled and deindexed. None of these seems to be terribly effective. Google is indexing pages with parameters in spite of the parameter (clicksource) being called out in GWT. Pages with obsolete URLs are indexed in spite of them having 301 redirects. Google also appears to be ignoring many of our canonical tags as well, despite the pages being identical. Any ideas on how to clean up the mess?

Last Panda: removed a lot of duplicated content but no still luck!
Hello here, my website virtualsheetmusic.com has been hit several times by Panda since its inception back in February 2011, and so we decided 5 weeks ago to get rid of about 60,000 thin, almost duplicate pages via noindex metatags and canonical (we have no removed physically those pages from our site giving back a 404 because our users may search for those items on our own website), so we expected this last Panda update (#25) to give us some traffic back... instead we lost an additional 10-12% traffic from Google and now it looks even really badly targeted. Let me say how disappointing is this after so much work! I must admit that we still have many pages that may look thin and duplicate content and we are considering to remove those too (but those are actually giving us sales from Google!), but I expected from this last Panda to recover a little bit and improve our positions on the index. Instead nothing, we have been hit again, and badly. I am pretty desperate, and I am afraid to have lost the compass here. I am particularly afraid that the removal of over 60,000 pages via noindex metatags from the index, for some unknown reason, has been more damaging than beneficial. What do you think? Is it just a matter of time? Am I on the right path? Do we need to wait just a little bit more and keep removing (via noindex metatags) duplicate content and improve all the rest as usual? Thank you in advance for any thoughts.

K3 duplicate page content and title tags
I'm running a Joomla site, have just installed k2 as our blogging platform. Our Crawl Report with SEOMOZ shows a good bit of duplicate content and duplicate title tags with our K2 blog. We've installed sh404SEF. Will I need to go into sh404SEF each time we generate a blog entry to point the titles to one URL? If there is something simpler please advise. Thank you, Don

Duplicate content resulting from js redirect?
I recently created a cname (e.g. m.client-site .com) and added some js (supplied by mobile site vendor to the head which is designed to detect if the user agent is a mobi device or not. This is part of the js: var CurrentUrl = location.href var noredirect = document.location.search; if (noredirect.indexOf("no_redirect=true") < 0){ if ((navigator.userAgent.match(/(iPhone|iPod|BlackBerry|Android.*Mobile|webOS|Window Now... Webmaster Tools is indicating 2 url versions for each page on the site - for example: 1.) /content-page.html 2.) /content-page.html?no_redirect=true and resulting in duplicate page titles and meta descriptions. I am not quite adept enough at either js or htaccess to really grasp what's going on here... so an explanation of why this is occurring and how to deal with it would be appreciated!

Can PDF be seen as duplicate content? If so, how to prevent it?
I see no reason why PDF couldn't be considered duplicate content but I haven't seen any threads about it. We publish loads of product documentation provided by manufacturers as well as White Papers and Case Studies. These give our customers and prospects a better idea off our solutions and help them along their buying process. However, I'm not sure if it would be better to make them non-indexable to prevent duplicate content issues. Clearly we would prefer a solutions where we benefit from to keywords in the documents. Any one has insight on how to deal with PDF provided by third parties? Thanks in advance.

ECommerce products duplicate content issues - is rel="canonical" the answer?
Howdy, I work on a fairly large eCommerce site, shop.confetti.co.uk. Our CMS doesn't allow us to have 1 product with multiple colour and size options so we created individual product pages for each product variation. This of course means that we have duplicate content issues. The layout of the shop works like this; there is a product group page (here is our disposable camera group) and individual product pages are below. We also use a Google shopping feed. I'm sure we're being penalised as so many of the products on our site are duplicated so, my question is this - is rel="canonical" the best way to stop being penalised and how can I implement it? If not, are there any better suggestions? Also, we have targeted some long-tail keywords in some of the product descriptions so will using rel-canonical effect this or the Google shopping feed? I'd love to hear experiences from people who have been through similar things and what the outcome was in terms of ranking/ROI. Thanks in advance.
