Large scale SEO duplicate content test

Do you have a large e-commerce site and think that you have your duplicate content under control? Here is a great and simple way to be sure; I would veer to bet that you are probably wrong assuming all is well.

Let’s pick on the largest e-commerce site as a test. Our friends at Amazon.com

First step, pick a manufacturer’s part number. It’s an easy way to assume you are looking at the same product. In this case I am going to use a very new IPOD, model # MA446LL/A.

Simply type in site:amazon.com MA446LL/A and you will find a large list of fairly similar pages. Some not so similar, but all in all why do you need 338 pages about one product?

I tried the same thing on buy.com and found 6 results, most in the supplemental listings, not so good. But they are not known for being strong at SEO.

Interesting. Maybe their old popular domains, with high trust level and PR are overpowering the dupe content problem.

Benj,

I think your right, Google must simply pick what it feels is the best result.

I have been in the search industry since the late 90’s, no not 10-20 years. My career started early in the search Day’s at Inktomi, where I supported large search portals. For example, MSN, AOL, iWon, Hotbot, CNet too name a few. After Inktomi I became a freelance consultant. I consulted for a few of the Top SEO’s around 2002 time frame; obviously the market has changed since then. After consulting I joined a small SEO firm called SEO Inc as the CTO. At SEO Inc. I successfully optimized some of the largest clients including IGN, Sony, VEGAS.com, Beaches and Sandals Resorts to name a few. Even though SEO Inc was a ton of fun, I still wanted the ultimate SEO challenge. I moved on as the global head of SEO for Shopping.com an eBay company. This challenge was an interesting one, how do I optimize a site with 50 million products? Every month I helped the business grow by leaps and bounds. I am now consulting for mostly enterprise e-commerce clients. Yes there is more too me than this profile shows, but you will just have to ask.
