James- Great question.....let me provide a little guidance.....we have a bunch of ecommerce sites we help manage for SEO.I am going to lump together several of googles "focus areas" into one. They are duplicate content, shallow content and copied duplicate content. Because with an ecommerce site, all 3 of these items can be the same or interchangeable thing.   Here are the major issues/things to focus on:Alot of ecommerce sites, in the past, have been able to generate substantial SEO value by listing products in variations of sizes and colors and with brief descriptions , and then create 1,000's of pages of what used to be considered unique content; (Shallow content). THOSE DAYS ARE GONE.  Assuming you still have the standard information copied and pasted on every page, that you mention above, ideally you want 250 unique words of description of a product.  Bare minimum you should have 100 words.....and in addition to the on-page content, you should make sure your meta descriptions are unique. Remember, Unique means relevant content that is different.  With duplicate content issues, google isn't penalizing you to hurt your ranking but they will only give you SEO value for the page they think is unique...for example if you have 40 pages of the same product but small variations in color or size or sku, and little to differentiate the pages, then they will count those 40 pages as 1 page....you lose the opportunity to build 39 pages of unique content value. The last thing to be careful of is if you have product that other companies have.....(you are a distributor or supplier or wholesaler and not the manufacturer). Then the manufacturer posts standard info and a bunch of people copy it and use it. YOU WILL BE PENALIZED BY GOOGLE FOR THIS BECAUSE IT IS COPIED DUPLICATE CONTENT. Most important point to remphasis----you know you are going to have some duplicate content on a website......you know that it it likely that if you are selling different variations of the same product, that you will have alot of the same stuff.....again, make sure you have unique and different content focused on your keywords. Target at least 50% different or unique content on each page as a MINIMUM.....Hope this helps.Mark
