Blog Duplicate Content
-
Hi, I have a blog, and like most blogs I have various search options (subject matter, author, archive, etc) which produce the same content via different URLs.
Should I implement the rel-canonical tag AND the meta robots tag (noindex, follow) on every page of duplicate blog content, or simply choose one or the other? What's best practice?
Thanks Mozzers! Luke

When you say "duplicate blog content", do you mean that the paths are creating duplicate URLs for the post themselves, or for that the tags, categories, etc. have overlapping search results?
If it's the latter (more common), I'd generally NOINDEX those. They aren't really duplicates, and canonical isn't appropriate in most of those cases. Agreed with @Boomajoom, though, it does depend on how integral those paths are for search. Some people use tags as major category navigation and build links to them. For others, the tags are just secondary navigation.
If your paths are all creating different URLs for the individual blog post, definitely use rel-canonical on those. That's a problem, and they are true duplicates. I'd even advise seeing if you can not do that - it's just messy long-term, and the perceived usability benefits are very, very small in my experience. It's almost never worth having multiple URLs for the same final page.

It depends. If you're getting traffic and links to your tag pages, then it wouldn't be worth it to de-index them. The general rule of thumb that I've followed is if I'm attracting traffic to tags or categories, I leave them in the index while adding canonical tags to individual post pages. But other people have other views and a lot of it is personal preference to how important those other pages are for you.

Consolidating two different domains to point at same site, duplicate content penalty?
I have two websites that are extremely similar and want to consolidate them into one website by pointing both domain names at one website. is this going to cause any duplicate content penalties by having two different domain names pointing at the same site? Both domains get traffic so i don't want to just discontinue one of the domains.

Duplicate Content / Canonical Conundrum on E-Commerce Website
Hi all, I’m looking for some expert advice on use of canonicals to resolve duplicate content for an e-Commerce site. I’ve used a generic example to explain the problem (I do not really run a candy shop). SCENARIO I run a candy shop website that sells candy dispensers and the candy that goes in them. I sell about 5,000 different models of candy dispensers and 10,000 different types of candy. Much of the candy fits in more than one candy dispenser, and some candy dispensers fit exactly the same types of candy as others. To make things easy for customers who need to fill up their candy dispensers, I provide a “candy finder” tool on my website which takes them through three steps: 1. Pick your candy dispenser brand (e.g. Haribo) 2. Pick your candy dispenser type (e.g. soft candy or hard candy) 3. Pick your candy dispenser model (e.g. S4000-A) RESULT: The customer is then presented with a list of candy products that they can buy. on a URL like this: Candy-shop.com/haribo/soft-candy/S4000-A All of these steps are presented as HTML pages with followable/indexable links. PROBLEM: There is a duplicate content issue with the results pages. This is because a lot of the candy dispensers fit exactly the same candy (e.g. S4000-A, S4000-B and S4000-C). This means that the content on these pages are the basically same because the same candy products are listed. I’ll call these the “duplicate dispensers” E.g. Candy-shop.com/haribo/soft-candy/S4000-A Candy-shop.com/haribo/soft-candy/S4000-B Candy-shop.com/haribo/soft-candy/S4000-C The page titles/headings change based on the dispenser model, but that’s not enough for the pages to be deemed unique by Moz. I want to drive organic traffic searches for the dispenser model candy keywords, but with duplicate content like this I’m guessing this is holding me back from any of these dispenser pages ranking. SOLUTIONS 1. Write unique content for each of the duplicate dispenser pages: Manufacturers add or discontinue about 500 dispenser models each quarter and I don’t have the resources to keep on top of this content. I would also question the real value of this content to a user when it’s pretty obvious what the products on the page are. 2. Pick one duplicate dispenser to act as a rel=canonical and point all its duplicates at it. This doesn’t work as dispensers get discontinued so I run the risk of randomly losing my canonicals or them changing as models become unavailable. 3. Create a single page with all of the duplicate dispensers on, and canonical all of the individual duplicate pages to that page. e.g. Canonical: candy-shop.com/haribo/soft-candy/S4000-Series Duplicates (which all point to canonical): candy-shop.com/haribo/soft-candy/S4000-Series?model=A candy-shop.com/haribo/soft-candy/S4000-Series?model=B candy-shop.com/haribo/soft-candy/S4000-Series?model=C PROPOSED SOLUTION Option 3. Anyone agree/disagree or have any other thoughts on how to solve this problem? Thanks for reading.

Implications of posting duplicate blog content on external domains?
I've had a few questions around the blog content on our site. Some of our vendors and partners have expressed interest in posting some of that content on their domains. What are the implications if we were to post copies of our blog posts on other domains? Should this be avoided or are there circumstances that this type of program would make sense?

Can pop-ups cause duplicate content issues in product pages?
Normally for ecommerce clients that have 100's of products we advise for size guides, installation guides etc to be placed as downloadable PDF resources to avoid huge blocks of content on multiple product pages. If content was placed in a popup e.g. fancybox, across multiple product pages would this be read by Google as duplicate content? Examples for this could be: An affiliate site with mutiple prices for a product and pop-up store reviews A clothing site with care and size guides What would be the best practice or setup?

Duplicate content - canonical vs link to original and Flash duplication
Here's the situation for the website in question: The company produces printed publications which go online as a page turning Flash version, and as a separate HTML version. To complicate matters, some of the articles from the publications get added to a separate news section of the website. We want to promote the news section of the site over the publications section. If we were to forget the Flash version completely, would you: a) add a canonical in the publication version pointing to the version in the news section? b) add a link in the footer of the publication version pointing to the version in the news section? c) both of the above? d) something else? What if we add the Flash version into the mix? As Flash still isn't as crawlable as HTML should we noindex them? Is HTML content duplicated in Flash as big an issue as HTML to HTML duplication?

Removing Duplicate Content Issues in an Ecommerce Store
Hi All OK i have an ecommerce store and there is a load of duplicate content which is pretty much the norm with ecommerce store setups e.g. this is my problem http://www.mystoreexample.com/product1.html
Intermediate & Advanced SEO | | ChriSEOcouk
http://www.mystoreexample.com/brandname/product1.html
http://www.mystoreexample.com/appliancetype/product1.html
http://www.mystoreexample.com/brandname/appliancetype/product1.html
http://www.mystoreexample.com/appliancetype/brandname/product1.html so all the above lead to the same product
I also want to keep the breadcrumb path to the product Here's my plan Add a canonical URL to the product page
e.g. http://www.mystoreexample.com/product1.html
This way i have a short product URL Noindex all duplicate pages but do follow the internal links so the pages are spidered What are the other options available and recommended? Does that make sense?
Is this what most people are doing to remove duplicate content pages? thanks 🙂0 -
Duplicate Content Through Sorting
I have a website that sells images. When you search you're given a page like this: http://www.andertoons.com/search-cartoons/santa/ I also give users the option to resort results by date, views and rating like this: http://www.andertoons.com/search-cartoons/santa/byrating/ I've seen in SEOmoz that Google might see these as duplicate content, but it's a feature I think is useful. How should I address this?
