The situation now: The project is not launched, but we have lot of categories and a big filter system in the end (color, brand, dimension, size, model, material,..).
Most of categories will have a product result page and a filter-sidebar. Sometimes also a unique text to help the customer which product to choose.
My problem are the deep filtered results:
This page has maybe 2 products to display, no unique text, no filterbar (is already filtered)... The products will also not indexed (too many - restricted by robots.txt).
First Idea Setting every page with less than 20 products to noindex. And additionally hide the links which targeting the result from google (prg pattern)?
