Multiple E-commerce website

[promodirect]

Following is a scenario where we plan to have a single database and different sites pulling product information from this. There will be a primary site with all the products listed and then there will be other category based website with the same products. All transactions will happen on respective website. The common factor will be products and its information.

Our question is should we have different item numbers for the same product listed on two websites or they can be the same.?
e.g.
Website A: Product - Blue Shoes and item number '123'
Product page url will be: websitea.com/blueshoes-123.html

Website B: Product - Blue Shoes and item number '123' or should the item# should be unique e.g. 'B123'
Product page url will be: websiteb.com/blueshoes-123.html
or
If item number is unique the product page url will be: websiteb.com/blueshoes-B123.html

Please advise what is the best way forward.

Having been there and done that I would warn against having two or more websites selling the same products with the same titles, numbers, pictures & descriptions.

If you must set up different domains with the same products then you must create two, three, (however many sites you have) different on page descriptions and preferable photographs, style titles, numbers and meta.

You should also consider the fact that it is likely that the sites will share a server and have the same cross site company information. Both of which can send negative information to Google and other search engines.

It is pure folly to expect to rank well for two or more sites selling exactly the same products with identical information. Not to mention the additional work associated with writing all the content, producing graphics and keeping the site up to date.

Hello Susan. I think that from Google's point of view, having the same URL on a different domain does not matter that much. What is a bigger problem is duplicate content. If you really want to launch two separate ecommerce websites with the same products, I think this is the issue you have to think about since you will have the same information for your products.
