    A website has duplicate content pages to make it easier for users to find the information from a couple spots in the site navigation. Site owner would like to keep it this way without hurting SEO.

    I've thought of using the robots.txt file to disallow search engines from crawling one of the pages. Would you think this is a workable/acceptable solution?

      Yeah, sorry for the confusion. I put the tag on all the pages (Original and Duplicate). I sent you a PM with another good article on Rel canonical tag

          Generally agree, although I'd just add that Robots.txt also isn't so great at removing content that's already been indexed (it's better at prevention). So, I find that it's not just not ideal - it sometimes doesn't even work in these cases.

          Rel-canonical is generally a good bet, and it should go on the duplicate (you can actually put it on both, although it's not necessary).

              per google webmaster tools:

              If Google knows that these pages have the same content, we may index only one version for our search results. Our algorithms select the page we think best answers the user's query. Now, however, users can specify a canonical page to search engines by adding a element with the attribute rel="canonical" to the section of the non-canonical version of the page. Adding this link and attribute lets site owners identify sets of identical content and suggest to Google: "Of all these pages with identical content, this page is the most useful. Please prioritize it in search results."

                Thanks Kyle. Anthony had a similar view on using the rel canonical tag. I'm just curious about adding it to both the original page or duplicate page? Or both?

                Thanks,

                Greg

                  Anthony, Thanks for your response. See Kyle, he also felt using the rel canonical tag was the best thing to do. However he seemed to think you'd put it on the original page - the one you want to rank for. And you're suggesting putting on the duplicate page. Should it be added to both while specifying which page is the 'original'?

                  Thanks!

                  Greg

                    I'm not sure I understand why the site owner seems to think that the duplicate content is necessary?

                    If I was in your situation I would be trying to convince the client to remove the duplicate content from their site, rather than trying to find a way around it.

                    If the information is difficult to find then this may be due to a problem with the site architecture. If the site does not flow well enough for visitors to find the information they need, then perhaps a site redesign is necessary.

                      Well, the answer would be yes and no. A robots.txt file would stop the bots from indexing the page, but links from other pages in site to that non indexed page could therefor make it crawlable and then indexed. AS posted in google webmaster tools here:

                      "You need a robots.txt file only if your site includes content that you don't want search engines to index. If you want search engines to index everything in your site, you don't need a robots.txt file (not even an empty one).

                      While Google won't crawl or index the content of pages blocked by robots.txt, we may still index the URLs if we find them on other pages on the web. As a result, the URL of the page and, potentially, other publicly available information such as anchor text in links to the site, or the title from the Open Directory Project (www.dmoz.org), can appear in Google search results."

                      I think the best way to avoid any conflict is applying the rel="canonical"  tag to each duplicate page that you don't want indexed.

                      You can find more info on rel canonical here

                      Hope this helps out some.

                        The best way would be to use the Rel canonical tag

                        On the page you would like to rank for put the Rel canonical tag in

                        This lets google know that this is the original page.

                        Check out this link posted by Rand about the Rel canonical tag [http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps](http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps)

                          Crawl Stats Decline After Site Launch (Pages Crawled Per Day, KB Downloaded Per Day)

                          Hi all, I have been looking into this for about a month and haven't been able to figure out what is going on with this situation. We recently did a website re-design and moved from a separate mobile site to responsive. After the launch, I immediately noticed a decline in pages crawled per day and KB downloaded per day in the crawl stats. I expected the opposite to happen as I figured Google would be crawling more pages for a while to figure out the new site. There was also an increase in time spent downloading a page. This has went back down but the pages crawled has never went back up. Some notes about the re-design: URLs did not change Mobile URLs were redirected Images were moved from a subdomain (images.sitename.com) to Amazon S3 Had an immediate decline in both organic and paid traffic (roughly 20-30% for each channel) I have not been able to find any glaring issues in search console as indexation looks good, no spike in 404s, or mobile usability issues. Just wondering if anyone has an idea or insight into what caused the drop in pages crawled? Here is the robots.txt and attaching a photo of the crawl stats. User-agent: ShopWiki Disallow: / User-agent: deepcrawl Disallow: / User-agent: Speedy Disallow: / User-agent: SLI_Systems_Indexer Disallow: / User-agent: Yandex Disallow: / User-agent: MJ12bot Disallow: / User-agent: BrightEdge Crawler/1.0 (crawler@brightedge.com) Disallow: / User-agent: * Crawl-delay: 5 Disallow: /cart/ Disallow: /compare/ ```[fSAOL0](https://ibb.co/fSAOL0)

                          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 https://www.google.com.au/search?espv=2&q=site%3Awww.mypetwarehouse.com.au+inurl%3Agclid&oq=site%3A&gs_l=serp.3.0.35i39l2j0i67l4j0i10j0i67j0j0i131.58677.61871.0.63823.11.8.3.0.0.0.208.930.0j3j2.5.0....0...1c.1.64.serp..8.3.419.nUJod6dYZmI 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.

                          Duplicate content on recruitment website

                          Hi everyone, It seems that Panda 4.2 has hit some industries more than others. I just started working on a website, that has no manual action, but the organic traffic has dropped massively in the last few months. Their external linking profile seems to be fine, but I suspect usability issues, especially the duplication may be the reason. The website is a recruitment website in a specific industry only. However, they posts jobs for their clients, that can be very similar, and in the same time they can have 20 jobs with the same title and very similar job descriptions. The website currently have over 200 pages with potential duplicate content. Additionally, these jobs get posted on job portals, with the same content (Happens automatically through a feed). The questions here are: How bad would this be for the website usability, and would it be the reason the traffic went down? Is this the affect of Panda 4.2 that is still rolling What can be done to resolve these issues? Thank you in advance.

                          A client of mine is about to launch into the USA market (currently only operating in Canada) and they are trying to find the best way to geo-target.  We recommended they go with the geo-targeted subfolder approach (___.com and ___.com/ca). I'm looking for any ways to assist in not getting these pages flagged for duplicate content. Your help is greatly appreciated. Thanks!

                          How to Remove Joomla Canonical and Duplicate Page Content

                          I've  attempted to follow advice from the Q&A section. Currently on the site www.cherrycreekspine.com, I've edited the .htaccess file to help with 301s - all pages redirect to www.cherrycreekspine.com. Secondly, I'd added the canonical statement in the header of the web pages. I have cut the Duplicate Page Content in half ... now  I have a remaining 40 pages to fix up. This is my practice site to try and understand what SEOmoz can do for me. I've looked at some of your videos on Youtube ... I feel like I'm scrambling around to the Q&A and the internet to understand this product. I'm reading the beginners guide.... any other resources would be helpful.
