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)

Large robots.txt file
We're looking at potentially creating a robots.txt with 1450 lines in it. This will remove 100k+ pages from the crawl that are all old pages (I know, the ideal would be to delete/noindex but not viable unfortunately) Now the issue i'm thinking is that a large robots.txt will either stop the robots.txt from being followed or will slow our crawl rate down. Does anybody have any experience with a robots.txt of that size?

Trailing Slashes for Magento CMS pages - 2 URLS - Duplicate content
Hello, Can anyone help me find a solution to Fixing and Creating Magento CMS pages to only use one URL and not two URLS? www.domain.com/testpage www.domain.com/testpage/ I found a previous article that applies to my issue, which is using htaccess to redirect request for pages in magento 301 redirect to slash URL from the non-slash URL. I dont understand the syntax fully in htaccess , but I used this code below. This code below fixed the CMS page redirection but caused issues on other pages, like all my categories and products with this error: "This webpage has a redirect loop ERR_TOO_MANY_REDIRECTS" Assuming you're running at domain root. Change to working directory if needed. RewriteBase / # www check If you're running in a subdirectory, then you'll need to add that in to the redirected url (http://www.mydomain.com/subdirectory/$1 RewriteCond %{HTTP_HOST} !^www. [NC]

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?

Soft 404's from pages blocked by robots.txt -- cause for concern?
We're seeing soft 404 errors appear in our google webmaster tools section on pages that are blocked by robots.txt (our search result pages). Should we be concerned? Is there anything we can do about this?

Are duplicate links on same page alright?
If I have a homepage with category links, is it alright for those category links to appear in the footer as well, or should you never have duplicate links on one page? Can you please give a reason why as well? Thanks!

How to resolve Duplicate Page Content issue for root domain & index.html?
SEOMoz returns a Duplicate Page Content error for a website's index page, with both domain.com and domain.com/index.html isted seperately. We had a rewrite in the htacess file, but for some reason this has not had an impact and we have since removed it. What's the best way (in an HTML website) to ensure all index.html links are automatically redirected to the root domain and these aren't seen as two separate pages?
