I have around 2000 pages on my site that are lists of items (15-80 items per list). Each item has a name an image and a description which get displayed in full, on the list page.
Each item on the list can be clicked and it will bring the user to a separate page for that individual item where users can leave comments. Other than comments, there is nothing on this page that isn't on the main list page. 95% of the time there are no comments meaning there is nothing unique at all on these pages.
Should I use a canonical tag on each of these item pages that points back to the full list or should it be noindex?
