Duplicate content in websites sharing the same database
Posted on 2011-04-26
I have a question about duplicate content that I cant seem to find answers for. I am building an e-commerce website that covers 4 main (but connected) areas, using a single database. We thought about putting up 4 websites, in order to utilize the domain for each of the 4 main department catagories. The sites will all have the same products, using the same titles and descriptions of each product - we cant change them site to site. (We have been considering just using 2 sites, each targeting 2 related catagories). These will all connect to the same database and shopping cart. We will be able to change everything except the product names and descriptions. We can add unique text to the home page, all the department/catagory pages can be unique and have their own versions of text, and we plan on adding many additional pages of information, videos and links in order to supply a lot of information about the products. These will also all be unique to each site.
We need to know the rammifications of doing this. If the only duplicate content are all the products titles and description,s will google drop one of the sites and just use the other? I dont know what percentage the duplicated content (all the products) are in comparison to the unique content, maybe 50%. What else might we have to deal with?
