How to separate different color for product and avoid duplicate content using parameters?
JOHN MEULLER (Webmaster Analyst from Google):
So if you have products in different colors, this is a general, I guess, e-commerce situation where you have one product and you have different variations of that product. I think this is something where you So if you have products in different colors, have different variations of that product. I think this is something where you have to make that call on your site where you say the individual variations are relevant enough that they’re worth indexing separately. Or maybe it makes more sense to concentrate ll of those variations into a single product page where you just say, this product is available in these different variations.So that’s something where you kind of have to make that decision on your side to say, these variations individually are critical enough that I want them indexed separately, or I prefer a stronger product page that just refers to these individual variations. So with colors, sometimes I could see that making sense, that people are searching for a specific color of a product and you want a specific landing page for that. Sometimes I can see it making sense that you just have a strong product page that mentions that it’s also available in these individual colors. So that’s not something where I’d focus primarily on the duplicate content point of view there but really think about how critical this variation, this specific page, is for your website or if it makes sense to fold that into a stronger product page instead.
