Question about duplicate listings on site for product listings.
-
We list products on our site and suspect that we have been hit by Panda as we are duplicating listings across our own site. Not intentionally, we just have multiple pages listings the same content as they fall into multiple categories.
Has anyone else had the same issue and if so how did you deal with it?.. Have you seen a change in results/rankings due to the changes you made?

Hello Nick,
It sounds like you're talking about category pages that link to product pages. I do recommend putting unique content on category pages, as they target different phases of a buying cycle (and keywords). For example...
"Blue Widgets" is a top-level category search.
"Blue Widgets for Men" is a category search."Men's V9 Blue Widget" (not the singular use of widget) is most likely a product search.
All three pages types should have their own unique content using keywords specific to that stage of the buying cycle, and displaying content that is useful to that stage of the buying cycle. For example...
"Blue Widgets" ---> Explain how to choose a blue widget. Which sub-category should they check out? Help them decide where to go next. Help them narrow their search.
"Men's Blue Widgets" ---> Explain the difference between brands and perhaps leading models. What are their needs and budget? Which are the high-end, top-of-the-line men's blue widgets, and which are affordable and reliable options, or entry-level widgets? Educate them.
"Men's V9 Blue Widget" ---> Explain the product. What are the features that either set it apart or make it a good value for the money?
The linking strategy can work this way as well. Naturally you're going to be passing pagerank from category pages into sub-categories and into products. This happens naturally on most sites because that is the natural flow of a purchasing path and a logical taxonomy. However you should also be passing pagerank back up if you want to help category pages rank. Enhanced produce descriptions give you an opportunity to do this.
Good luck!

Thanks for the detailed response Tom..
We have for example
A = Listings page with brief of all products
linking to B,C,D,E,F,G etc.. which are all specific pages for those products..
The B - G's rank ok for non competitive terms on the page but page's A dont rank so well.
The problem about no indexing A is that I think the other pages will get lost and have importance taken away from them..
Canonical from second pages of A listings yes, but what I was also thinking to do is put some unique content on page A in order to make that page more unique..Any thoughts on that?

Hi there
There are a few options here. Both revolve around making sure only version of your product listings is instructed to be indexed, so that you can promote that version via SEO.
The first solution would be to 301 redirect any duplications to one version of your product listings. This is the quickest and most absolute solution to duplicate listings, as it ensures only version of them remains live. However, depending on your CMS, this might not be possible.
The second solution would be to add robots instructions to the duplicate listings that instructs Google not to index those pages. You can do this by either adding code to the page itself or by using a robots.txt file. The code you'd need to add to the tag on the page is - however, if your CMS is producing duplicate URLs but only using one physical page, you may want to avoid this as it could block all versions of the page. In which case, you could add each duplicate URL to your robots.txt file, specifying you'd like to block them from being indexed, such as:
User Agent: *
Disallow: /example-page-1
Disallow: /example-page-2And so on. I like this robots.txt tutorial guide to learn more about how you can do this.
Finally, you could add canonical tags to each page to specify which version of the URL is the one you want to rank and be indexed, which should prevent others from being considered as well. For example, for a product listing page like: http://www.example.com/category-1/product-page-version-1 - if you want that page to be indexed, you will want to add a canonical tag in the of the code that reads:
Now, if that is the only physical web page that exists and your CMS generates additional, duplicate URLs with how it works, you will only need to add that canonical once. However, if other webpages actually exist in your CMS and server, you will need to add the same tag to the other duplicate pages. This basically tells Google and Bing: "Hey, this page is a duplicate, ignore this one and rank this one instead". Moz has a great guide on canonical usage here.
Dr. Pete also wrote a guide guide on canonical usage and how you can use it for products that are pretty much the same, but have slight differences such as sizes, colour etc.
I hope this helps answer your question - remember, the key here is to instruct Google that you don't want them to index the duplicates and that you don't have them to manipulate rankings. You're trying to have only one version indexed, and if others exist outside of redirects, you have instructed which version should be kept and which ones ignored.

With the New Panda update supposedly only weeks away, is it wise to No Index my products I have not had time to rewrite the product descriptions for ?
Hi Mozzers, I read on SEJ yesterday than apparently the Panda update was due in the 2 - 4 weeks. I still have a large of my products which I have not got around to rewriting unique product descriptions for. I know these product descriptions are duplicated on other affiliate sites so do it think it in light of the panda update coming , would it wise to put a NO INDEX Meta tag on these product pages until I get around to rewriting the descriptions. That way, I may not hit my Panda and it will buy me a bit more time. Just an idea , but thought I'd run it by. thanks Pete

What recommendations do you have for the SEO of this site?
Hello, Could you glance at this site and let me know if you see anything we could improve upon? www.nlpca.com A couple of notes: We're over-optimized for the term "NLP" on the home page. We're removing the footer links soon. We have 2 locations: San Francisco, CA and Salt Lake City, UT. Our main keyword is "NLP Training" but we would like to rank higher for the keyword "NLP". Also note that we're completely white hat, but we have international site-wide backlinks, and a couple of site-wide backlinks in site's footers - all friends and colleagues of ours.

Avoiding Duplicate Content - Same Product Under Different Categories
Hello, I am taking some past advise and cleaning up my content navigation to only show 7 tabs as opposed to the 14 currently showing at www.enchantingquotes.com. I am creating a "Shop by Room" and "Shop by Category" link, which is what my main competitors do. My concern is the duplicate content that will happen since the same item will appear in both categories. Should I no follow the "Shop by Room" page? I am confused as to when I should use a no follow as opposed to a canonical tag? Thank you so much for any advise!

To list or not to list? Products that contain basic info only, yet show off product depth...
Some of our products on our site only have 40 characters of description... each item/category is it's own unique web page with basic info like Brand, Model, What it is, Price, & Quantity in stock. For searchers knowing what they want, they can quickly find us via the basic info & see that we have it in stock. But for someone surfing our site, it's not all that attractive or informative as you are scrolling down the category list. Collecting the picture & info can be a slow and time consuming process, but something we'd love to be all caught up on one day. Would it be wiser to take these pages off, or keep them on until they are fully updated with pic & more detail? (My thought is that even though they don't contain a lot of individual detail depth, they still add a substantial quantity of basic related content to the category page that they reside in. This basic info on these items are also given a chance to burn into the web search engines over a longer period of time. As time goes by and their content is improved, they will get re-crawled/re-indexed with their new information depth. Also, even though they don't look all that pretty, it shows off our product depth... if we only listed the items that looked spectacular, then a lot of our categories would only contain a wimpy 3 out of 30 items that we actually have for sale. That feels like a huge misrepresentation of how much selection we actually have to offer. But perhaps this is wrong thinking?) Thanks, Kevin

Bing still not listing my site after 3 weeks, Google ranks very very low
I am scared that somehow the search engines are penalizing me for something, but I don't know what. The site can be found at http://www.hypnotherapy-guide.com It is a business directory/advice/guide site listing a lot of hypnotherapists (9000). Is it possible that such a large site popping up over night is flagged by the SE as spam? I don't know what I am doing wrong.

Hello, people. I have a quick question regarding search in Google. I use search operator [site:url] to see indexing stauts of my site. Today, I was checking indexing status and I found that Google shows different numbers of indexed pages depends on search setting. 1. At default setting (set as 10 search result shows) > I get about 150 pages indexed by Google. 2. I set 100 results shows per page and tried again. > I get about 52 pages indexed by Google. Of course I used same page URL. I really want to know which data is accurate. Please help people!!
