Duplicate eCommerce Product Descriptions
-
I know that creating original product descriptions is best practices. What I don't understand is how other sites are able to generate significant traffic while still using duplicate product descriptions on all product pages. How are they not being penalized by Google?
-
From my experience as an SEO for a large eCommerce site (our own products), I tend to think that Google has a way of recognizing eCommerce site from purely informational ones and takes that into consideration when analyzing content.
As you say Chris, many producers will distribute their catalogs to all their dealers and they in turn will put those online. The same happens with our products here. Our dealers use the very description we provide them with and no one has ever been penalized for that.
As said, I personally think that Google takes the intent of your site (eCommerce, informational etc. ) into consideration when slapping duplicate content penalties.
Having said that, i have no data to back up that claim so go easy on me, it's only based on my gut feeling and practical observations.

I can definitely understand the frustration, but Google won't penalize sites for simply having duplicate content, and especially storefronts. Many merchants are provided with photos and product descriptions by the distributor, and when you're talking about hundreds or even thousands of products, it just not feasible for a merchant to change all of the descriptions and even more so if your inventory is changing on a monthly or even weekly basis. Then all of your changes get overwritten with the new upload.
A good example would be the SMC websites that you see on late night TV where they send out a CD with products to thousands of customers and 98% of them just upload the database into their stores with little to no alteration. They won't be penalized, but they just won't be able to sell much.
In those cases, the sites aren't going to be penalized. And if those sites are ranking well without changing the content, then Google is definitely looking at other factors to make that decision (traffic, bounce rate, time on site, etc.).
The sites Google are penalizing are the ones that intentionally try to game the system by stripping content from other sites and reposting them with literally no changes at all. Also sites that try to duplicate one of their stores multiple times in a cookie cutter fashion in order to trick the system to see if they can get multiple listings on the SERPs.
You haven't provided specific sites to review for a definitive answer here, but they don't sound like they're trying to do anything black hat. They're just lazy. But if your site will be selling the same products, altering your descriptions and images is the only way that you'll get the advanatage over them instead of just becoming "yet another one of those sites". Good luck!

Thanks for the Amazon comment Chris :). I understand the multitude of variables when asking this question but after looking at a group of sites with similar backlink profiles, site architecture, etc. and all use duplicate product descriptions I am taken aback that they are not penalized. Even looking at smaller sites that are not properly constructed or optimized use duplicate product descriptions and still drive traffic/rank. Then I read all about rewriting product descriptions from SEOMoz and others (this information gels with what I know to be true) but then see sites still rank with this thin/dupe content.
Any thoughts?

That could be for a variety of reasons. Is that site the only one that is offering that particular product? Is it a highly trafficked site with a lot of backlinks, reviews, and online activity? Are the pages simply coded properly using canonical tags which help them escape "wrath"? These are all valid questions when you're doing competitive analysis and all things that Google considers along with dozens of other considerations.
Your best practice is to create new descriptions, take new photos or alter the existing ones (add text, crop, change contrast, etc.). This way your listing is seen as fresh and original content and will eventually take precedence over their carbon copy approach. If you have a better page with better content that's more informative to the customer, Google will choose your listing over 20 other sites that all have the same photos and descriptions.
Originality always wins....in most cases. Keep in mind that there are many other considerations in the Google algorithms, so don't expect to beat out Amazon no matter how hard you try.

Canonicalising a product with multiple variants
I am working with an ecommerce site and have encountered an issue I haven't come across before and would appreciate some advice on how to proceed. There are multiple variation products with one master product and then up to 20 or 30 variant products, the variation could be colour, size or both. The site has been set up to canonicalise all the variations to the master variant product, which I understand to be best practice. But, this is where the issue occurs, the master variant product URL 302 redirects to one of the variant product URLs. Example below. My question is, is this harmful to our SEO efforts? Would be be best to canonicalise to a preferred colour or size variation? EXAMPLE: Master variant product: www.example.co.uk/primary-category/product-123 Seeing this product on the page and clicking will 302 redirect to www.example/co.uk/primiary-category/product-123/colour-456 On page www.example/co.uk/primiary-category/product-123/colour-456 the canonical tag is www.example.co.uk/primary-category/product-123 Any help with this would be greatly appreciated.

Alt Tags on multiple product images
Hi I work on SEO for an ecommerce site and wanted to find out how important it is to optimise all images with alt tags. We have alt tags in place, however have not optimised descriptions for the following example images: Front of cupboard Back of cupboard Side of cupboard etc Is this dangerous for SEO if these images all have the same alt tag? We have thousands of products so it would be a huge job to update these, but if it's crucial for SEO we can work through our priorities. Thank you!

Meta descriptions for subpages in the SERPs
Hey Mozzers! Something occurred to me the other day was that, while we can write title tags and meta descriptions to be within the character count and therefore appear nice and neatly in the SERPs, when Google et al decide to pull subpages out as further site links, it seems to still pull the normal meta description but with a far lower character count. As this looks untidy and could potentially impact CTR, is there a way I can amend the preferred text for the shortened version, via Webmaster Tools, for example? Thanks in advance for your help! Nick.

Duplicate Content - Blog Rewriting
I have a client who has requested a rewrite of 250 blog articles for his IT company. The blogs are dispersed on a variety of platforms: his own website's blog, a business innovation website, and an IT website. He wants to have each article optimised with keyword phrases and then posted onto his new website thrice weekly. All of this is in an effort to attract some potential customers to his new site and also to establish his company as a leader in its field. To what extent would I need to rewrite each article so as to avoid duplicating the content? Would there even be an issue if I did not rewrite the articles and merely optimised them with keywords? Would the articles need to be completely taken by all current publishers? Any advice would be greatly appreciated.

Different page for each product colour?
Hi Guys, I've just read an ecommerce article that suggests it's a good idea to have a different page for each colour that the product comes in. However surely this will mean duplicate content? What are your thoughts? Have you put this tactic into motion and how did it go? Thanks, Dan

Percentage of duplicate content allowable
Can you have ANY duplicate content on a page or will the page get penalized by Google? For example if you used a paragraph of Wikipedia content for a definition/description of a medical term, but wrapped it in unique content is that OK or will that land you in the Google / Panda doghouse? If some level of duplicate content is allowable, is there a general rule of thumb ratio unique-to-duplicate content? thanks!
