I've never used the "nofollow" attribute, and am wondering if it would be a good idea to use it for this purpose: basically, some of my store pages have titles such as Green Widgets Page 1 and Green Widgets Page 2 -- where I simply can't break down the categories any further, yet don't want to make the pages too long. So I'm wondering if, to avoid duplicate (or nearly duplicate) content issues, I should block the search engines from spidering beyond "Page 1"?
Or is there something else I should be doing (like not even worrying about this at all)?
Thanks very much.
