4000 new duplicate products on our ecommerce site, potential impact?
-
Hello,
We've currently got 9500 products live on our site at the moment with ~2000 in this category that we're adding the new products in. All of these products we're adding are coming from a site that we own and we're trying to expand the range on our site (the 9500 product site has a lot more visitors than the 4000 product site).
However, all these products imported I believe are atleast duplicates from the 4000 product site, but the first ones I have seen (500) are manufacturer duplicates.
What issues are we potentially going to run in to?
Just for extra information:
We have no control over canonical/noindex/robots etc

You're likely to see problems resulting from a few different factors:
- Search engines go through a limited number of pages on your site, known as a crawl budget. Around a third of that budget will go cataloguing duplicate products, which is a waste since those pages will be discarded since...
- If a search engine sees two pages with the same content only one will rank. This means there is no point from an SEO perspective to having those 4,000 extra pages, since nobody will land on them
- Because you're providing content that sin't high quality the rest of the site may well get hit by Panda, bringing the rest of your rankings down
- Customers will see the two identical products, spend a bit of time trying to figure out the difference between them, get frustrated, then buy from somebody else
If you're looking at convincing your boss not to do this then here's the important bit: add those products and you risk getting fewer people to your site and fewer of those people turning into customers.

Is the 4000 product site still going to exist or is it being stripped and moved to the 9500 product site? If everything is getting completely moved from one site to the other then you really do need to find out who has access to canonicals or 301 redirects so you can move the sites properly. If the smaller site is staying up and selling those products still, realize you'd be canibalizing your own traffic potentially and could wind up with shoddy rankings from all the scraped/dupe content.
Since you have no access to Canonical/NoIndex/Robots/etc. the question is, what do you have access to? Do you need to move all these products over? Are they exact duplicate of things you have on your site already? If its an exact duplicate of something you offer then you probably shouldn't add a duplicate page but you should canonical or 301 if you were able to. If they're close but have slight differences then you might be better served by adding a new product option to the existing page for the similar product in order to better serve the consumer, instead of diluting rankings with something so similar. Though you till might need that canonical or redirect to ensure everything is targeted properly.

Sounds as if you shouldn't be adding all of those--there could potentially be severe consequences if you don't deal with them properly. That severe consequence could be that you are hit by a Google Panda penalty, and lost a huge majority of your site's traffic from organic search.
You really do need to deal with this in some way--either don't add them like you're doing or use the canonical tag.

Sounds like a duplicate content issue. You may not get penalized but you could potentially see a drop in rankings.

Avoiding duplicate content in manufacturer's [of single product] website
Hello, So I have read a lot of articles about duplicate content/ keyword canibalism/ competing with yourself, and so on. But none of these articles really fit to manufacturer website who produces one product. For example, lets say I make ceramic tiles, this means: Homepage: "Our tiles are the best tiles, we have numerous designs of tiles. We make them only from natural ceramic" Product list: "Here is a list of our tiles: Poesia tile, white tile, textured tile, etc" Page for each tile: Gallery: a bunch of images trying to prove that these tiles look best 🙂 Where to buy page: a map From what I understand this page is already doomed - it will not go well against larger retailers who don't focus only on tiles but they sell everything. This page is set to have a lot of duplicate content. But I hope I am wrong, can someone please make some suggestions how to do SEO on such a website where all pages are about the same thing? Any help would be much appreciated! Juris

Ecommerce Site homepage , Is it okay to have Links as H2 Tags as that is relevant to the page ?
Hi All, I have a Rental site and I am bit confused with how best do my H Tags on my homepage I know the H1 is the most important, Then H2 Tags and so on.. and that these tags should really be titles for content. However, I have a few categories (links) on my homepage so I am wondering if I could put these as H2 Tags given that it is relevant to the page . H3 Tags will my News and Guides etc , H4 Tags will the whats on the footer. I am attached a made up screenshot of what I propose for my homepage if someone could please give it a quick look , it would be very much appreciated. I have looked at what some competitors do a lot of them don't seem to have h2's etc but I know it's an important factor for rankings etc. Many thanks Pete dJSFQwI

Duplicate Content: Is a product feed/page rolled out across subdomains deemed duplicate content?
A company has a TLD (top-level-domain) which every single product: company.com/product/name.html The company also has subdomains (tailored to a range of products) which lists a choosen selection of the products from the TLD - sort of like a feed: subdomain.company.com/product/name.html The content on the TLD & subdomain product page are exactly the same and cannot be changed - CSS and HTML is slightly differant but the content (text and images) is exactly the same! My concern (and rightly so) is that Google will deem this to be duplicate content, therfore I'm going to have to add a rel cannonical tag into the header of all subdomain pages, pointing to the original product page on the TLD. Does this sound like the correct thing to do? Or is there a better solution? Moving on, not only are products fed onto subdomain, there are a handfull of other domains which list the products - again, the content (text and images) is exactly the same: other.com/product/name.html Would I be best placed to add a rel cannonical tag into the header of the product pages on other domains, pointing to the original product page on the actual TLD? Does rel cannonical work across domains? Would the product pages with a rel cannonical tag in the header still rank? Let me know if there is a better solution all-round!

Redirecting Pages from site A to site B
Hi, I have a client who have a solid, high ranking content based site (site A). They have now created an ecommerce site in addition (site B). To give site B a boost in terms of search engine visibility upon launch, they now wish to redirect approx 90% of site As pages to site B. What would be the implications of this? Apart from customers being automatically redirected from the page they thought they where landing on, how would google now view site A? What are your thoughts to thier idea. I am trying to talk them out of it as I think its a poor one.

Duplicate content across hundreds of Local sites and they all rank #1
Usually when we discuss duplicate content, we're addressing the topic of penalties or non-indexing. In this case, we're discussing ranking high with duplicate content. I've seen lots of dental, chiropractor and veterinarian sites built by companies that give them cookie cutter sites with the same copy. And they all rank #1 or #2. Here are two companies that do that:

http://mysocialpractice.com/about/ The later uses external blogs to provide inbound links to their clients' site, but not all services do that, in fact, this is the first time I've seen them with external blogs. Usually the blog with duplicate copy is ON SITE and the sites still rank #1. Query "Why Your Smile Prefers Water Over Soft Drinks" to see duplicate content on external blogs. Or "Remember the Mad Hatter from the childhood classic, Alice in Wonderland? Back then, the process of making hats involved using mercury compounds. Overexposure could produce symptoms referred to as being" for duplicate content on chiropractor sites that rank high. I've seen well optimized sites rank under them even though their sites have just as much quality content and it's all original with more engagement and inbound links. It appears to me that Google is turning a blind eye on duplicate content. Maybe because these are local businesses with local clientele it doesn't care that a chiropractor in NY has the same content as one in CA, just as the visitor doesn't care because the visitor in CA isn't look at a chiropractor's site in NY generally. So maybe geo-targeting the site has something to do with it. As a test, I should take the same copy and put it on a non-geo-targeted site and see if it will get indexed. I asked another Local SEO expert if she has run across this, probably the best in my opinion. She has and she finds it difficult to rank above them as well. It's almost as if Google is favoring those sites. So the question is, should all dentists, chiropractors and veterinarians give it up to these services? I shudder to think that, but, hey it's working and it's a whole lot less work - and maybe expense - for them.0 -

URL for New Product
Hi, We are creating a section on our established existing website to display our new marketplace product & associated category pages. This marketplace will be a section of the site where our users can sell online training courses that they've created. It will be branded on our site as the Marketplace. Is it important to include 'marketplace' in the URL? Or would it be better to include a relevant keyword such as 'training-courses' instead? Or both? I've assumed I shouldn't use both as that would increase the length of the URLs and number of subfolders.

Should product searches (on site searches) be noindex?
We have a large new site that is suffering from a sitewide panda like penalty. The site has 200k pages indexed by Google. Lots of category and sub category page content and about 25% of the product pages have unique content hand written (vs the other pages using copied content). So it seems our site is labeled as thin. I'm wondering about using noindex paramaters for the internal site search. We have a canonical tag on search results pointing to domain.com/search/ (client thought that would help) but I'm wondering if we need to just no index all the product search results. Thoughts?
