I have a Magento site. In order to reduce duplicate content for products of the same style but with different colours I have combined them on to 1 product page.
I would like to allow the pictures to be dynamic, i.e. allow a user to search for a colour and all the products that offer that colour appear in the results, but I dont want the default product image shown but the product image for that colour applying to the query.
Therefore to do this I have to append a query string to the end of the URL to produce this result:
www.website.com/category/product-name.html?=red
My question is, will the query variations then be picked up as duplicate content:
Google suggest it has contingencies in its algorithm and I will not be penalised:

But other sources suggest this is not accurate. Note the article was written in 2007.
