Duplicate Product Pages On Niche Site
-
I have a main site, and a niche site that has products for a particular category. For example, Clothing.com is the main site, formalclothing.com is the niche site.
The niche site has about 70K product pages that have the same content (except for navigation links which are similar, but not dupliated).
I have been considering shutting down the niche site, and doing a 301 to the category of the main site. Here are some more details:
-
The niche sites ranks fairly well on Yahoo and Bing. Much better than the main site for keywords relevant to that category.
-
The niche site was hit with Penguin, but doesn't seem to have been effected much by Panda.
-
When I analyze a product page on the main site using copyscape, 1-2 pages of the niche site do show, but NOT that exact product page on the niche site.
Questions:
-
Given the information above, how can I gauge the impact the duplicate content is having if any?
-
Is it a bad idea to do a canonical tag on the product pages of the niche site, citing the main site as the original source?
-
Any other considerations aside from duplicate content or Penguin issue when deciding to 301?
-
Would you 301 if this was your site?
Thanks in advance.

Haven't read anything or experimented with using canonical link elements to indicate your preferred domain. You should have server redirects in your Apache/Nginx config file for this and also set the preferred domain in GWT to really take care of that issue.
Yes, Google will certainly decide for you if you don't have other indicators on which site you want to rank for select keywords. I suppose you'll need to decide which site to keep, but if you want both then you've got a lot of work ahead of you. Ideally, you should be ranking each product page on each site for unique keywords rather than duplicating efforts and wasting resources on trying to rank the same product page on two different sites for the same keywords. Not sure why anyone would want to do that for any other reason than testing.
Anyway, my strong advice is pick a site and then merge the other site into it. If you're using Magento or WooCommerce or some other mainstream e-com platform, this should be rather easy, if not just time consuming. If they are different platforms, then I recommend Magento or a custom solution for best technical SEO features. If you can share more details about your job, I'd be glad to help.

Thanks for the response.
I have used the canonical tag on both sites to deal with www/non-www issues. Both sites have a single URL for each product.
The duplicate product page issue is with the content on the body of the product page. Both the same on both sites. So I have:
www.mainsite.com/product123.html and www.nichesite.com/product123.html
I checked the page title of some products in Google with quotes, only 1 product page shows up, either from the main site or the niche site. So it seems that Google is already deciding with each product page which site to show.

My question to you is why shut down the niche site if it's ranking better than the main site? There is surely some risk of taking a short-term hit when merging these two sites, but I'm confident in suggesting that combining the traffic from the two sites will eventually earn similar organic ranking of your niche site pages for the same keywords.
Yes, 301 redirect your pages to the new domain if possible. If you run into technical challenges with this, use MOZ to see which pages rank the highest and prioritize those redirects to the main site domain.
You stated "The niche site has about 70K product pages that have the same content (except for navigation links which are similar, but not dupliated). " I understand this to mean you found 70k products with the same/similar content on both the main site and niche site. If you simply ran a report that told you you had 70k product pages with duplicate content, I'd make sure to check your URL structure for www subdomain, trailing slashes, and the variation of both, i.e., www.domain.com/product, www.domain.com/product/, domain.com/product, domain.com/product/. These are technically all different URLs, so double check that and reply.
If you really have the same pages, obviously you'll need to fix that if combining the two sites. If you don't combine them, cross-domain canonicalization is an option (http://googlewebmastercentral.blogspot.com/2009/12/handling-legitimate-cross-domain.html and https://support.google.com/webmasters/answer/1716747?hl=en).

I think a bit more would go into the consideration whether or not to 301 the site like branding, social activity, conversion rate differences, and market segments served. If everything just folds into the main site better than keeping it separate in the niche, then I'd go for it. Here's a nice case study of a company that had an issue kind of similar to yours: http://moz.com/blog/2-become-1-merging-two-domains-made-us-an-seo-killing. Reading through that post will help with seeing things that they looked at in order consider merging the two domains. Cheers!

Google Search Console Not Indexing Pages
Hi there! I have a problem that I was hoping someone could help me with. On google search console, my website does not seem to be indexed well. In fact, even after rectifying problems that Moz's on-demand crawl has pointed out, it still does not become "valid". There are some of the excluded pages that Google has pointed out. I have rectified some of the issues but it doesn't seem to be helping. However, when I submitted the sitemap, it says that the URLs were discoverable, hence I am not sure why they can be discovered but are not deemed "valid". I would sincerely appreciate any suggestions or insights as to how can I go about to solve this issue. Thanks! Screenshot+%28341%29.png Screenshot+%28342%29.png Screenshot+%28343%29.png

Why Google changed our page-title suddenly which has been same for years
Hi all, I know Google shows a different page titles. Happens when over optimised or when we copied competitors page title. But we did neither. Suddenly Google changed our homepage page title in search results. Our page title suffix "brand name" has been moved to beginning. Our page title is still for years.

Your search - site:domain.com - did not match any documents.
I've recently started work on a new clients website and done some preliminary work with on-page optimisation, and there is still plenty of work to be done and issues to resolve. They are ranking ok on Bing, but they are not getting any ranking on Google at all (except paid) - I tried the site:domain.com search and comes up with no results... so this confirms that something is going on with the google search rank! Can anyone shed light on what can cause this or why this would happen? My next step is to look at their webmaster tools (haven't had access yet), but if anyone has any tips to resolve this or where to look, that would be great! Thanks!

Multiple products with legitimate duplicate descriptions
We are redeveloping a website for a card company who have far too many products to write unique descriptions for each. Even if they could I don't think it would be beneficial to the user. However they do have unique descriptions for each range which is useful for users viewing an individual card. Which is better practice: a) Ignore the duplicate content issue and supply the user with info about the range b) Provide clear enticing links to find out more about the range which will leave the individual card page a little void of content. Many thanks

Are there any specific tips to how to gain traffic from very short lived search terms? If the site you are SEO/SEMing want to go for search related to things like the latest celebrity breakup, or a fashion event that lasts less than a week The onsite stuff seems pretty good as SEO onsite tools generally give it an A grade Is it just a case of doing the same stuff as normal, but faster? 😉

Too Many Non-Niche-Specific Links?
Something just occurred to me today. I work in-house for an embroidered patch company, but I respond to a lot of HARO queries about Marketing, SEO, SEM, Web Design, ect. So, we have a lot of links from these types of sites. Additionally, I have done guest blogs on these topics because those are what I'm knowledgeable about. We also have links from customers' personal blogs or websites stating they got their patches from us and are happy, blah, blah, blah. On top of that, we hired someone who ended up getting tons of .edu links by spamming blogs. Oy. I'd estimate only about 10% of our links come from embroidery, sewing, screen printing, promotional products, etc types of sites. I guess it's not really known or documented how much weight Google places on niche-specific links--we just assume that it matters, and I'm sure it does. Our rankings are fine now, but I'm looking for some opinions from other SEOs about how much they think this will matter in the future or how much it matters now. Could this hurt us in the future? .
