I am new to SEOmoz & trying to work my way through the ca-trillion errors that have been found on my site, but for each one I want to ensure that I am helping rather than harming my site. The tool has (as a "notice") said that my category pages & Archives are NO-INDEX, is this how these pages should be dealt with? In addition, the crawler has also (as a "warning error) discovered that my categories, and Archives do not have a meta description..is this of great importance for non indexed pages of this type? Thanks so much to the SEOmoz forum members, you have so far been of invaluable help to me.
