Thanks CleverPhD,
That's a very interesting read by Adam Audette too, thanks.
I should say that there's no internal search, each tab has a series of duplicated 'blurbs' taken from the product's unique landing page, while the body copy remains the same across the slight variations in the URL. So with:
example.com/example/?st=BlueWidgets
example.com/example/?st=RedSocks
all of these will feature the same body copy, while the last two will have a series of small descriptions from other landing pages in the site. Would the canonical tag be appropriate in this case? We only need to index 'example.com/example'.
Also, does the rel next prev take into account duplicate content? We want only the main URL indexed as all the paginated pages feature duplicate content, there is no view all page however.
Many thanks
