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:

Correct robots.txt for WordPress
Hi. So I recently launched a website on WordPress (1 main page and 5 internal pages). The main page got indexed right off the bat, while other pages seem to be blocked by robots.txt. Would you please look at my robots file and tell me what‘s wrong? I wanted to block the contact page, plugin elements, users’ comments (I got a discussion space on every page of my website) and website search section (to prevent duplicate pages from appearing in google search results). Looks like one of the lines is blocking every page after ”/“ from indexing, even though everything seems right. Thank you so much. FzSQkqB.jpg

Duplicate content in sidebar
Hi guys. So I have a few sentences (about 50 words) of duplicate content across all pages of my website (this is a repeatable text in sidebar). Each page of my website contains about 1300 words (unique content) in total, and 50 words of duplicate content in sidebar. Does having a duplicate content of this length in sidebar affect the rankings of my website in any way? Thank you so much for your replies.

How to fix duplicate content for homepage and index.html
Hello, I know this probably gets asked quite a lot but I haven't found a recent post about this in 2018 on Moz Q&A, so I thought I would check in and see what the best route/solution for this issue might be. I'm always really worried about making any (potentially bad/wrong) changes to the site, as it's my livelihood, so I'm hoping someone can point me in the right direction. Moz, SEMRush and several other SEO tools are all reporting that I have duplicate content for my homepage and index.html (same identical page). According to Moz, my homepage (without index.html) has PA 29 and index.html has PA 15. They are both showing Status 200. I read that you can either do a 301 redirect or add rel=canonical I currently have a 301 setup for my http to https page and don't have any rel=canonical added to the site/page. What is the best and safest way to get rid of duplicate content and merge the my non index and index.html homepages together these days? I read that both 301 and canonical pass on link juice but I don't know what the best route for me is given what I said above. Thank you for reading, any input is greatly appreciated!

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 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

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
