Solve duplicate content issues by using robots.txt
-
Hi,
I have a primary website and beside that I also have some secondary websites with have same contents with primary website. This lead to duplicate content errors. Because of having many URL duplicate contents, so I want to use the robots.txt file to prevent google index the secondary websites to fix the duplicate content issue. Is it ok?
Thank for any help!
-
yes, robots.txt is the bad way, I will try to use canonical tag. Thanks for your help!

Using robots.txt is perhaps not the best way of doing it. Using the canonical or a noindex meta tag would likely be best. I think the reasons for this are best summed up in this article which explains, probably better than I could, why robots.txt is not the best way of dealing with duplicate content. Hope this helps.

I have tried to use cross-domain canonical, but this is too difficult for me. So, I want to confirm if I use the robots.txt file is ok or not?
Thanks

Why not use a cross-domain canonical whereby you reference the pages on your primary website as the canonical version on your secondary websites, thereby eliminating the duplication.
For example on each page that is duplicate on your secondary website you would add the following to the head to reference the primary pages:

How do I fix duplicate page issue on Shopify with duplicate products because of collections.
I'm working with a new client with a site built on Shopify. Most of their products appear in four collections. This is creating a duplicate content challenge for us. Can anyone suggest specific code to add to resolve this problem. I'm also interested in other ideas solutions, such as "don't use collections" if that's the best approach. I appreciate your insights. Thank you!

Duplicate content on partner site
I have a trade partner who will be using some of our content on their site. What's the best way to prevent any duplicate content issues? Their plan is to attribute the content to us using rel=author tagging. Would this be sufficient or should I request that they do something else too? Thanks

Duplicate Content from on Competitor's site?
I've recently discovered large blocks of content on a competitors site that has been copy and pasted from a client's site. From what I know, this will only hurt the competitor and not my client since my guy was the original. Is this true? Is there any risk to my client? Should we take action? Dino

Does schema.org assist with duplicate content concerns
The issue of duplicate content has been well documented and there are lots of articles suggesting to noindex archive pages in WordPress powered sites. Schema.org allows us to mark-up our content, including marking a components URL. So my question simply, is no-indexing archive (category/tag) pages still relevant when considering duplicate content? These pages are in essence a list of articles, which can be marked as an article or blog posting, with the url of the main article and all the other cool stuff the scheme gives us. Surely Google et al are smart enough to recognise these article listings as gateways to the main content, therefore removing duplicate content concerns. Of course, whether or not doing this is a good idea will be subjective and based on individual circumstances - I'm just interested in whether or not the search engines can handle this appropriately.

How do you block development servers with robots.txt?
When we create client websites the urls are client.oursite.com. Google is indexing theses sites and attaching to our domain. How can we stop it with robots.txt? I've heard you need to have the robots file on both the main site and the dev sites... A code sample would be groovy. Thanks, TR

Avoiding "Duplicate Page Title" and "Duplicate Page Content" - Best Practices?
We have a website with a searchable database of recipes. You can search the database using an online form with dropdown options for: Course (starter, main, salad, etc)

Cooking Method (fry, bake, boil, steam, etc)
Preparation Time (Under 30 min, 30min to 1 hour, Over 1 hour) Here are some examples of how URLs may look when searching for a recipe: find-a-recipe.php?course=starter
find-a-recipe.php?course=main&preperation-time=30min+to+1+hour
find-a-recipe.php?cooking-method=fry&preperation-time=over+1+hour There is also pagination of search results, so the URL could also have the variable "start", e.g. find-a-recipe.php?course=salad&start=30 There can be any combination of these variables, meaning there are hundreds of possible search results URL variations. This all works well on the site, however it gives multiple "Duplicate Page Title" and "Duplicate Page Content" errors when crawled by SEOmoz. I've seached online and found several possible solutions for this, such as: Setting canonical tag Adding these URL variables to Google Webmasters to tell Google to ignore them Change the Title tag in the head dynamically based on what URL variables are present However I am not sure which of these would be best. As far as I can tell the canonical tag should be used when you have the same page available at two seperate URLs, but this isn't the case here as the search results are always different. Adding these URL variables to Google webmasters won't fix the problem in other search engines, and will presumably continue to get these errors in our SEOmoz crawl reports. Changing the title tag each time can lead to very long title tags, and it doesn't address the problem of duplicate page content. I had hoped there would be a standard solution for problems like this, as I imagine others will have come across this before, but I cannot find the ideal solution. Any help would be much appreciated. Kind Regards5
