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:

Solve Redirect Chains
I've gotten a few Redirect Issues that involve Redirect Chains, with the https:// version redirecting to the www. version and then redirecting to the right URL. Here is an example:

Schermafbeelding 2021-12-07 om 11.04.32.png I've tried setting a direct redirect between the first and the last URL, but WordPress doesn't seem to allow that (it's overwritten). I've also tried checking the internal links to make sure that none of the links are the first one. They don't seem to be there. Does anyone have any tips on solving these Redirect Chains?0 -
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 do I fix my portfolio causing duplicate content issues?
Hi, Im new to this whole duplicate content issue. I have a website, fatcatpaperie.com that I use the portofolio feature in Wordpress as my gallery for all my wedding invitations. I have a ton of duplicate content issues from this. I don't understand at all how to fix this. I'd appreciate any help! Below is an example of one duplicate content issue. They have slightly different names, different urls, different images and all have no text. But are coming up as duplicates. Would it be as easy as putting a different metadescription for each??

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

Would it be bad to change the canonical URL to the most recent page that has duplicate content, or should we just 301 redirect to the new page?
Is it bad to change the canonical URL in the tag, meaning does it lose it's stats? If we add a new page that may have duplicate content, but we want that page to be indexed over the older pages, should we just change the canonical page or redirect from the original canonical page? Thanks so much! -Amy
