Could you use a robots.txt file to disalow a duplicate content page from being crawled?

 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

 Peter, Thanks for the clarification.

 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).

 Next time I'll read the reference links better  Thank you!

 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)

		How can I avoid duplicate content for a new landing page which is the same as an old one?
 Hello mozers! I have a question about duplicate content for you... One on my clients pages have been dropping in search volume for a while now, and I've discovered it's because the search term isn't as popular as it used to be. So... we need to create a new landing page using a more popular search term. The page which is losing traffic is based on the search query "Can I put a solid roof on my conservatory" this only gets 0-10 searches per month according to the keyword explorer tool. However, if we changed this to "replacing conservatory roof with solid roof" this gets up to 500 searches per month. Muuuuch better! The issue is, I don't want to close down and re-direct the old page because it's got a featured snippet and sits in position 1. So I'd like to create another page instead... however, as the two are effectively the same content, I would then land myself in a duplicate content issue. If I were to put a rel="canonical" tag in the original "can I put a solid roof...." page but say the master page is now the new one, would that get around the issue?

		Should I use the on classified listing pages that have expired?
 We have went back and forth on this and wanted to get some outside input. I work for an online listing website that has classified ads on it. These ads are generated by companies on our site advertising weekend events around the country. We have about 10,000 companies that use our service to generate their online ads. This means that we have thousands of pages being created each week. The ads have lots of content: pictures, sale descriptions, and company information. After the ads have expired, and the sale is no longer happening, we are currently placing the in the heads of each page. The content is not relative anymore since the ad has ended. The only value the content offers a searcher is the images (there are millions on expired ads) and the descriptions of the items for sale. We currently are the leader in our industry and control most of the top spots on Google for our keywords. We have been worried about cluttering up the search results with pages of ads that are expired. In our Moz account right now we currently have over 28k crawler warnings alerting us to the being in the page heads of the expired ads. Seeing those warnings have made us nervous and second guessing what we are doing. Does anybody have any thoughts on this? Should we continue with placing the in the heads of the expired ads, or should we be allowing search engines to index the old pages. I have seen websites with discontinued products keeping the products around so that individuals can look up past information. This is the closest thing have seen to our situation. Any help or insight would be greatly appreciated! -Matt Intermediate & Advanced SEO | | mellison0

		Can I use duplicate content in different US cities without hurting SEO?
 So, I have major concerns with this plan. My company has hundreds of facilities located all over the country. Each facility has it's own website. We have a third party company working to build a content strategy for us. What they came up with is to create a bank of content specific to each service line. If/when any facility offers that service, they then upload the content for that service line to that facility website. So in theory, you might have 10-12 websites all in different cities, with the same content for a service. They claim "Google is smart, it knows its content all from the same company, and because it's in different local markets, it will still rank." My contention is that duplicate content is duplicate content, and unless it is "localize" it, Google is going to prioritize one page of it and the rest will get very little exposure in the rankings no matter where you are. I could be wrong, but I want to be sure we aren't shooting ourselves in the foot with this strategy, because it is a major major undertaking and too important to go off in the wrong direction. SEO Experts, your help is genuinely appreciated! Intermediate & Advanced SEO | | MJTrevens1

		Using hreflang for international pages - is this how you do it?
 My client is trying to achieve a global presence in select countries, and then track traffic from their international pages in Google Analytics. The content for the international pages is pretty much the same as for USA pages, but the form and a few other details are different due to how product licensing has to be set up. I don’t want to risk losing ranking for existing USA pages due to issues like duplicate content etc. What is the best way to approach this? This is my first foray into this and I’ve been scanning the MOZ topics but a number of the conversations are going over my head,so suggestions will need to be pretty simple 🙂 Is it a case of adding hreflang code to each page and creating different URLs for tracking. For example: Intermediate & Advanced SEO | | Caro-O
 URL for USA: https://company.com/en-US/products/product-name/
 URL for Canada: https://company.com/en-ca/products/product-name /
 URL for German Language Content: https://company.com/de/products/product-name /
 URL for rest of the world: https://company.com/en/products/product-name /1

		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.

		Duplicate content on ecommerce sites
 I just want to confirm something about duplicate content. On an eCommerce site, if the meta-titles, meta-descriptions and product descriptions are all unique, yet a big chunk at the bottom (featuring "why buy with us" etc) is copied across all product pages, would each page be penalised, or not indexed, for duplicate content? Does the whole page need to be a duplicate to be worried about this, or would this large chunk of text, bigger than the product description, have an effect on the page. If this would be a problem, what are some ways around it? Because the content is quite powerful, and is relavent to all products...
