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 - 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.

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

Does schema.org assist with duplicate content concerns
The issue of duplicate content has been well documented and there are lots of articles suggesting to noindex archive pages in WordPress powered sites. Schema.org allows us to mark-up our content, including marking a components URL. So my question simply, is no-indexing archive (category/tag) pages still relevant when considering duplicate content? These pages are in essence a list of articles, which can be marked as an article or blog posting, with the url of the main article and all the other cool stuff the scheme gives us. Surely Google et al are smart enough to recognise these article listings as gateways to the main content, therefore removing duplicate content concerns. Of course, whether or not doing this is a good idea will be subjective and based on individual circumstances - I'm just interested in whether or not the search engines can handle this appropriately.

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?

Percentage of duplicate content allowable
Can you have ANY duplicate content on a page or will the page get penalized by Google? For example if you used a paragraph of Wikipedia content for a definition/description of a medical term, but wrapped it in unique content is that OK or will that land you in the Google / Panda doghouse? If some level of duplicate content is allowable, is there a general rule of thumb ratio unique-to-duplicate content? thanks!

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
