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:

Duplicate Content with ?Page ID's in WordPress
Hi there, I'm trying to figure out the best way to solve a duplicate content problem that I have due to Page ID's that WordPress automatically assigns to pages. I know that in order for me to resolve this I have to use canonical urls but the problem for me is I can't figure out the URL structure. Moz is showing me thousands of duplicate content errors that are mostly related to Page IDs For example, this is how a page's url should look like on my site Moz is telling me there are 50 duplicate content errors for this page. The page ID for this page is 82 so the duplicate content errors appear as follows and so on. For 47 more pages. The problem repeats itself with other pages as well. My permalinks are set to "Post Name" so I know that's not an issue. What can I do to resolve this? How can I use canonical URLs to solve this problem. Any help will be greatly appreciated.

Duplicate Content - Blog Rewriting
I have a client who has requested a rewrite of 250 blog articles for his IT company. The blogs are dispersed on a variety of platforms: his own website's blog, a business innovation website, and an IT website. He wants to have each article optimised with keyword phrases and then posted onto his new website thrice weekly. All of this is in an effort to attract some potential customers to his new site and also to establish his company as a leader in its field. To what extent would I need to rewrite each article so as to avoid duplicating the content? Would there even be an issue if I did not rewrite the articles and merely optimised them with keywords? Would the articles need to be completely taken by all current publishers? Any advice would be greatly appreciated.

What's the best practice for handling duplicate content of product descriptions with a drop-shipper?
We write our own product descriptions for merchandise we sell on our website. However, we also work with drop-shippers, and some of them simply take our content and post it on their site (same photos, exact ad copy, etc...). I'm concerned that we'll loose the value of our content because Google will consider it duplicated. We don't want the value of our content undermined... What's the best practice for avoiding any problems with Google? Thanks, Adam

Sliders and Content Above the Fold
I was just inspecting a wire frame that is going out to a client and realized that the slider may interfere with the "content above the fold." Can't believe this had not struck me on others. If the Header has basic business info, etc. in it and you place a slider to display images in the area just beneath the Header or slightly down from it, does that decrease the amount of content seen a being above the fold? Or, is content above the fold established by virtue of H1,2, 3, etc.?

Can I use the first sentence of my page content as a meta description tag as well?
I just want to copy my content on the page and use the first or as well the second sentence of the content self for my meta description tag. Is that OK? Or should the Meta description tag be different?

Best practice for franchise sites with duplicated content
I know that duplicated content is a touchy subject but I work with multiple franchise groups and each franchisee wants their own site, however, almost all of the sites use the same content. I want to make sure that Google sees each one of these sites as unique sites and does not penalize them for the following issues. All sites are hosted on the same server therefor the same IP address All sites use generally the same content across their product pages (which are very very important pages) *templated content approved by corporate Almost all sites have the same design (A few of the groups we work with have multiple design options) Any suggestions would be greatly appreciated. Thanks Again Aaron

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.
