Moz Q&A is closed.
After more than 13 years, and tens of thousands of questions, Moz Q&A closed on 12th December 2024. Whilst we’re not completely removing the content - many posts will still be possible to view - we have locked both new posts and new replies. More details here.
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)

Directory with Duplicate content? what to do?
Moz keeps finding loads of pages with duplicate content on my website. The problem is its a directory page to different locations. E.g if we were a clothes shop we would be listing our locations: www.sitename.com/locations/london www.sitename.com/locations/rome www.sitename.com/locations/germany The content on these pages is all the same, except for an embedded google map that shows the location of the place. The problem is that google thinks all these pages are duplicated content. Should i set a canonical link on every single page saying that www.sitename.com/locations/london is the main page? I don't know if i can use canonical links because the page content isn't identical because of the embedded map. Help would be appreciated. Thanks.

Is it a problem to use a 301 redirect to a 404 error page, instead of serving directly a 404 page?
We are building URLs dynamically with apache rewrite.
Intermediate & Advanced SEO | | lcourse
When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page, So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404? Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).0 -
No-index pages with duplicate content?
Hello, I have an e-commerce website selling about 20 000 different products. For the most used of those products, I created unique high quality content. The content has been written by a professional player that describes how and why those are useful which is of huge interest to buyers. It would cost too much to write that high quality content for 20 000 different products, but we still have to sell them. Therefore, our idea was to no-index the products that only have the same copy-paste descriptions all other websites have. Do you think it's better to do that or to just let everything indexed normally since we might get search traffic from those pages? Thanks a lot for your help!

Do you add 404 page into robot file or just add no index tag?
Hi, got different opinion on this so i wanted to double check with your comment is. We've got /404.html page and I was wondering if you would add this page to robot text so it wouldn't be indexed or would you just add no index tag? What would be the best approach? Thanks!

Artist Bios on Multiple Pages: Duplicate Content or not?
I am currently working on an eComm site for a company that sells art prints. On each print's page, there is a bio about the artist followed by a couple of paragraphs about the print. My concern is that some artists have hundreds of prints on this site, and the bio is reprinted on every page,which makes sense from a usability standpoint, but I am concerned that it will trigger a duplicate content penalty from Google. Some people are trying to convince me that Google won't penalize for this content, since the intent is not to game the SERPs. However, I'm not confident that this isn't being penalized already, or that it won't be in the near future. Because it is just a section of text that is duplicated, but the rest of the text on each page is original, I can't use the rel=canonical tag. I've thought about putting each artist bio into a graphic, but that is a huge undertaking, and not the most elegant solution. Could I put the bio on a separate page with only the artist's info and then place that data on each print page using an <iframe>and then put a noindex,nofollow in the robots.txt file?</p> <p>Is there a better solution? Is this effort even necessary?</p> <p>Thoughts?</p></iframe>

Copying my Facebook content to website considered duplicate content?
I write career advice on Facebook on a daily basis. On my homepage users can see the most recent 4-5 feeds (using FB social media plugin). I am thinking to create a page on my website where visitors can see all my previous FB feeds. Would this be considered duplicate content if I copy paste the info, but if I use a Facebook social media plugin then it is not considered duplicate content? I am working on increasing content on my website and feel incorporating FB feeds would make sense. thank you

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 Press Release?
Hi, We recently held a charity night in store. And had a few local celebs turn up etc... We created a press release to send out to various media outlets, within the press release were hyperlinks to our site and links on certain keywords to specific brands on our site. My question is, should we be sending a different press release to each outlet to stop the duplicate content thing, or is sending the same release out to everyone ok? We will be sending approx 20 of these out, some going online and some not. So far had one local paper website, a massive football website and a local magazine site. All pretty much same content and a few pics. Any help, hints or tips on how to go about this if I am going to be sending out to a load of other sites/blogs? Cheers
