That makes sense. But I really want to make sure I (and others) understand because of EGOL's earlier referenced comments (June 2011).
"If I kept my category pages out of the search indexes I would be walking away from hundreds of search engine visitors per minute.
Do analytics to see how much traffic is coming into these pages from search, who is linking to them, how much revenue they earn and also consider their future traffic potential.
Its not good to follow generalized advice blindly." and (February 2012) ...
"I have two wordpress blogs and category pages are where most of my search engine traffic enters. Some bring in thousands per month. Most of my post pages bring in very little traffic.
If you are not having any problem with duplicate content at present maybe it would be a good idea to allow indexing of the main page, the post pages and the category pages. They if you do have a duplicate content problem you can remove from the index the pages that bring in the least amount of traffic."
So is the key then, ensuring the category pages contain unique content in addition to whatever else is on the category pages? I would have thought the mere fact that you're creating a unique combination of unique content by the grouping excerpts from identically tagged posts might have been enough. That content would also get updated each time a new post gets published.
I'd appreciate your thoughts on this Erica.
