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:
On-Page Optimization | | Billywig
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 'meta title' issue (AMP & NON-AMP Pages)

On-Page Optimization | | 21centuryweb
example.com/amp We have set the 'meta title' in desktop version & we don't want to change the title for AMP page as we have more than 10K pages on the website. ----As per SEMRUSH Tool---- ABOUT THIS ISSUE It is a bad idea to duplicate your title tag content in your first-level header. If your page’s <title>and <h1> tags match, the latter may appear over-optimized to search engines. Also, using the same content in titles and headers means a lost opportunity to incorporate other relevant keywords for your page.</p> <p><strong>HOW TO FIX IT</strong></p> <p>Try to create different content for your <title> and <h1> tags.<br /><br />this is what they are recommending, for the above issue we have asked our team to create unique meta and post title for desktop version but what about AMP page?<br /><br />Please help!</p></title>0 -
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!

Should I use an acronym in my URL?
I know that Google understands various acronyms. Example: If I search for CRM System, it knows i'm searching for a customer relationship management system. However, will it recognize less known acronyms? I have a page geared specifically for SAP data archiving for human capital management systems. For those in the industry, they simply call it HCM. Here is how I view my options: Option #1: www.mywebsite.com/sap-data-archiving/human-capital-management Option #2: www.mywebsite.com/sap-data-archiving/hcm Option #3: www.mywebsite.com/sap-data-archiving/hcm-human-capital-management With option #3, i'm capturing the acronym AND the full phrase. This doesn't make my URL overly long either. Of course, in my content i'll reference both. What does everyone else think about the URL? -Alex

Duplicate page titles and Content in Woocommerce
Hi Guys, I'm new to Moz and really liking it so far!
On-Page Optimization | | jeeyer
I run a eCommerce site on Wordpress + WooCommerce and ofcourse use Yoast for SEO optimalisation I've got a question about my first Crawl report which showed over 600 issues! 😐 I've read that this is something that happens more often (http://moz.com/blog/setup-wordpress-for-seo-success). Most of them are categorized under:
1. Duplicate Page Titles or;
2. Duplicate Page Content. Duplicate Page Titles:
These are almost only: product category pages and product tags. Is this problem beeing solved by giving them the right SEO SERP? I see that a lot of categories don't have a proper SEO SERP set up in yoast! Do I need to add this to clear this issue, or do I need to change the actual Title? And how about the Product tags? Another point (bit more off-topic) I've read here: http://moz.com/community/q/yoast-seo-plugin-to-index-or-not-to-index-categories that it's advised to noindex/follow Categories and Tags but isn't that a wierd idea to do for a eCommerce site?! Duplicate Page Content:
Same goes here almost only Product Categories and product tags that are displayed as duplicate Page content! When I check the results I can click on a blue button for example "+ 17 duplicates" and that shows me (in this case 17 URLS) but they are not related to the fist in any way so not sure where to start here? Thanks for taking the time to help out!

Duplicate Content when Using "visibility classes" in responsive design layouts? - a SEO-Problem?
I have text in the right column of my responsive layout which will show up below the the principal content on small devices. To do this I use visibility classes for DIVs. So I have a DIV with with a unique style text that is visible only on large screen sizes. I copied the same text into another div which shows only up only on small devices while the other div will be hidden in this moment. Technically I have the same text twice on my page. So this might be duplicate content detected as SPAM? I'm concerned because hidden text on page via expand-collapsable textblocks will be read by bots and in my case they will detect it twice?Does anybody have experiences on this issue?bestHolger

How do i block an entire category/directory with robots.txt?
Anyone has any idea how to block an entire product category, including all the products in that category using the robots.txt file? I'm using woocommerce in wordpress and i'd like to prevent bots from crawling every single one of products urls for now. The confusing part right now is that i have several different url structures linking to every single one of my products for example www.mystore.com/all-products, www.mystore.com/product-category, etc etc. I'm not really sure how i'd type it into the robots.txt file, or where to place the file. any help would be appreciated thanks
