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 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.

Does using Yoast variables for meta content overwrite any pages that already have custom meta content?
The question is about the Yoast plugin for WP sites. Let's say I have a site with 200 pages and custom meta descriptions / title tags already in place for the top 30 pages. If I use the Yoast variable tool to complete meta content for the remaining pages (and make my Moz issue tracker look happier), will that only affect the pages without custom meta descriptions or will it overwrite even the pages with the custom meta content that I want? In this situation, I do want to keep the meta content that is already in place on select pages. Thanks! Zack

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 penalty
when moz crawls my site they say I have 2x the pages that I really have & they say I am being penalized for duplicate content. I know years ago I had my old domain resolve over to my new domain. Its the only thing that makes sense as to the duplicate content but would search engines really penalize me for that? It is technically only on 1 site. My business took a significant sales hit starting early July 2013, I know google did and algorithm update that did have SEO aspects. I need to resolve the problem so I can stay in business

Duplicate Content for Men's and Women's Version of Site
So, we're a service where you can book different hairdressing services from a number of different salons (site being worked on). We're doing both a male and female version of the site on the same domain which users are can select between on the homepage. The differences are largely cosmetic (allowing the designers to be more creative and have a bit of fun and to also have dedicated male grooming landing pages), but I was wondering about duplicate pages. While most of the pages on each version of the site will be unique (i.e. [male service] in [location] vs [female service] in [location] with the female taking precedent when there are duplicates), what should we do about the likes of the "About" page? Pages like this would both be unique in wording but essentially offer the same information and does it make sense to to index two different "About" pages, even if the titles vary? My question is whether, for these duplicate pages, you would set the more popular one as the preferred version canonically, leave them both to be indexed or noindex the lesser version entirely? Hope this makes sense, thanks!

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 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
