Your most relevant category pages will takeover positions of products, but this won't change your traffic in any way.
I realize that page rank can't be "sculpted" by using noindex, and that by noindexing a bunch of product pages, the way that page rank flows through a site would be seriously changed
...but what about all the (internal) links back to the category page from the product pages.
Suppose you have a category called Iron Widgets. And in that category you had several individual products, like 15 Inch Tall Iron Widget, or Japanese Forged Iron Widget, and stuff like that.
And due to the fact that their isn't a HUGE difference between one widget and another, the description of each widget product page kind of overlaps with the description of all the other widget product pages.
...if you were targeting, eg, a particular piece of clothing, like a shirt, you might be able to manage to include characteristics like color, size, and pattern all on one page without skewing the search targeting. These are characteristics I wouldn't normally try to target on separate pages anyway. I'd normally leave these choices to the option values in the ordering interface. The lists of colors, sizes, and patterns that would appear in your source html would in fact be expected.
Ensure your product pages titles, are structured differently to the category pages, to ensure that a product page, won't be fighting for traffic against a category page.
If your website is anything like mine, despite category pages individually receiving most traffic, the product pages traffic, when added up together, far exceeds the category pages.
Have you suffered a loss in traffic, which leads you to believe these pages my be an issue?
Keep the product pages, differentiate those that are for different products and perhaps combine some that aren't (eg, those that are for basically the same product but just different heights or colors)... and make the links to the product pages as accessible as possible from your category pages.
An important point. I try to make pages more specific the deeper they are. The anchor text that's on category pages linking to the product pages should be less specific than the titles and headings on the product pages themselves. The product pages are where the greatest differentiation needs to take place.
My only concern is that what a human considers significantly different and what an alogrithim considers significantly different are often two separate animals...
...The product pages are where the greatest differentiation needs to take place.
Hmm... To me that seems ALMOST like a contradiction, but that might be because I am misinterpreting your use of the word "differentiation" here.
When I see that, I think that means the individual product pages should have MORE TEXT than the category level page (which is hierarchically directly above it). Maybe I am not interpreting that correctly?
Your most relevant category pages will takeover positions of products, but this won't change your traffic in any way.
Hmm... I am interested in why you say this. Could you elaborate further?
Furthermore, you may actually damage the rankings and keyword reach of those category pages for a number of reasons. If you have (sensible) breadcrumbs product pages going to be pushing and concentrating link juice upwards to their parents. If there's social interactions on your product pages they're lost to view. If there's spiderable UGC (like reviews)- often great, original, keyword-rich fodder - that's going to be invisible to the search engines. And, of course, fundamentally you're going to be losing the semantic strength of your product titles, descriptions and (perhaps) images and videos.
How about direct emails requesting a review of the product, sent after a short period of time to those who made purchases?
Could it be possible that meta noindexing product-level pages would actually boost ranking for category pages- no.
