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:

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 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?? Thanks for the help!

How to exclude URL filter searches in robots.txt
When I look through my MOZ reports I can see it's included 'pages' which it shouldn't have included i.e. adding filtering rules such as this one http://www.mydomain.com/brands?color=364&manufacturer=505 How can I exclude all of these filters in the robots.txt? I think it'll be: Disallow: /*?color=$ Is that the correct syntax with the $ sign in it? Thanks!

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.

What's the best practice for handling duplicate content of product descriptions with a drop-shipper?
We write our own product descriptions for merchandise we sell on our website. However, we also work with drop-shippers, and some of them simply take our content and post it on their site (same photos, exact ad copy, etc...). I'm concerned that we'll loose the value of our content because Google will consider it duplicated. We don't want the value of our content undermined... What's the best practice for avoiding any problems with Google? Thanks, Adam

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!

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
