I've a website with 6 pages identified as 'duplicate content' because they are very similar. This pages looks similar because are the same but it show some pictures, a few, about the product category that's why every page look alike each to each other but they are not 'exactly' the same. So, it's any way to indicate to Google that the content is not duplicated?
I guess it's been marked as duplicate because the code is 90% or more the same on 6 pages.
I've been reviewing the 'canonical' method but I think is not appropriated here as the content is not the same.
Any advice (that is not add more content)?
