How to deal with category browsing and duplicate content
-
On an ecommerce site there are typically a lot of pages that may appear to be duplications due to category browse results where the only difference may be the sorting by price or number of products per page.
How best to deal with this? Add nofollow to the sorting links? Set canonical values that ignore these variables? Set cononical values that match the category home page?
Is this even a possible problem with Panda or spiders in general?
-
Can Google deal with "search engine safe" parameters? I added our sort stuff to Webmaster tools but I'm not sure Google knows what to do and can't find any info on this.
-
That makes sense but should I be doing anything with rel canonical to make sure that each sort option doesn't display a different canonical url?

For Google, you can go into your Webmaster Tools, and go to the Site configuration > URL parameters page. You can set the parameters in your URLs to things like "Sorts", "Paginates", or "Narrows", so that Google will know how the parameter changes the info on the page. Once Google knows how the parameter effects the page, presumably they'll give the right links and display URLs in their search results.

Duplicate content across domains?
Does anyone have suggestions for managing duplicate product/solution website content across domains? (specifically parent/child company domains) Is it advisable to do this? Will it hurt either domain? Any best practices when going down this path?

Duplicate Content Question With New Domain
Hey Everyone, I hope your day is going well. I have a question regarding duplicate content. Let's say that we have Website A and Website B. Website A is a directory for multiple stores & brands. Website B is a new domain that will satisfy the delivery niche for these multiple stores & brands (where they can click on a "Delivery" anchor on Website A and it'll redirect them to Website B). We want Website B to rank organically when someone types in " <brand>delivery" in Google. Website B has NOT been created yet. The Issue Website B has to be a separate domain than Website A (no getting around this). Website B will also pull all of the content from Website A (menus, reviews, about, etc). Will we face any duplicate content issues on either Website A or Website B in the future? Should we rel=canonical to the main website even though we want Website B to rank organically?</brand>

Do I need to add the actual language for meta tags and description for different languages? cited for duplicate content for different language
Hi, I am fairly new to SEO and this community so pardon my questions. We recently launched on our drupal site mandarin language version for the entire site. And when i do the crawl site, i get duplicate content for the pages that are in mandarin. Is this a problem or can i ignore this? Should i make different page titles for the different languages? Also, for the metatag and descriptions, would it better in the native language for google to search for? thanks in advance.

How do I best handle Duplicate Content on an IIS site using 301 redirects?
The crawl report for a site indicates the existence of both www and non-www content, which I am aware is duplicate. However, only the www pages are indexed**, which is throwing me off. There are not any 'no-index' tags on the non-www pages and nothing in robots.txt and I can't find a sitemap. I believe a 301 redirect from the non-www pages is what is in order. Is this accurate? I believe the site is built using asp.net on IIS as the pages end in .asp. (not very familiar to me) There are multiple versions of the homepage, including 'index.html' and 'default.asp.' Meta refresh tags are being used to point to 'default.asp'. What has been done: 1. I set the preferred domain to 'www' in Google's Webmaster Tools, as most links already point to www. 2. The Wordpress blog which sits in a /blog subdirectory has been set with rel="canonical" to point to the www version. What I have asked the programmer to do: 1. Add 301 redirects from the non-www pages to the www pages. 2. Set all versions of the homepage to redirect to www.site.org using 301 redirects as opposed to meta refresh tags. Have all bases been covered correctly? One more concern: I notice the canonical tags in the source code of the blog use a trailing slash - will this create a problem of inconsistency? (And why is rel="canonical" the standard for Wordpress SEO plugins while 301 redirects are preferred for SEO?) Thanks a million! **To clarify regarding the indexation of non-www pages: A search for 'site:site.org -inurl:www' returns only 7 pages without www which are all blog pages without content (Code 200, not 404 - maybe deleted or moved - which is perhaps another 301 redirect issue).

Virtual Domains and Duplicate Content
So I work for an organization that uses virtual domains. Basically, we have all our sites on one domain and then these sites can also be shown at a different URL. Example: sub.agencysite.com/store sub.brandsite.com/store Now the problem comes up often when we move the site to a brand's URL versus hosting the site on our URL, we end up with duplicate content. Now for god knows what damn reason, I currently cannot get my dev team to implement 301's but they will implement 302's. (Dont ask) I also am left with not being able to change the robots.txt file for our site. They say if we allowed people to go in a change this stuff it would be too messy and somebody would accidentally block a site that was not supposed to be blocked on our domain. (We are apparently incapable toddlers) Now I have an old site, sub.agencysite.com/store ranking for my terms while the new site is not showing up. So I am left with this question: If I want to get the new site ranking what is the best methodology? I am thinking of doing a 1:1 mapping of all pages and set up 302 redirects from the old to the new and then making the canonical tags on the old to reflect the new. My only thing here is how will Google actually view this setup? I mean on one hand I am saying

"Hey, Googs, this is just a temp thing." and on the other I am saying "Hey, Googs, give all the weight to this page, got it? Graci!" So with my limited abilities, can anybody provide me a best case scenario?0 -
ECommerce syndication & duplicate content
We have an eCommerce website with original software products. We want to syndicate our content to partner and affiliate websites, but are worried about the effect of duplicate content all over the web. Note that this is a relatively high profile project, where thousands of sites will be listing hundreds of our products, with the exact same name, description, tags, etc. We read the wonderful and relevant post by Kate Morris on this topic (here: http://mz.cm/nXho02) and we realize the duplicate content is never the best option. Some concrete questions we're trying to figure out: 1. Are we risking penalties of any sort? 2. We can potentially get tens of thousands of links from this concept, all with duplicate content around them, but from PR3-6 sites, some with lots of authority. What will affect our site more - the quantity of mediocre links (good) or the duplicate content around them (bad)? 3. Should we sacrifice SEO for a good business idea?

Duplicate Content on Blog
I have a blog I'm setting up. I would like to have a mini-about block set up on every page that gives very brief information about me and my blog, as well as a few links to the rest of the site and some social sharing options. I worry that this will get flagged as duplicate content because a significant amount of my pages will contain the same information at the top of the page, front and center. Is there anything I can do to address this? Is it as much of a concern as I am making it? Should I work on finding some javascript/ajax method for loading that content into the page dynamically only for normal browser pageviews? Any thoughts or help would be great.
