Those stats are quite scary with extremely high bounce rates.
You are quire right - I am not proud of them. Floundering here trying to figure out how to reduce the bounce rate. (traffic is about 85% organic search.)
Can you clarify if the articles are part of the site or in a blog?
They are in a wordpress blog which is on the same domain as the eCommerce site. (i.e., mydomain.com/blog/ )
Most of the articles interlink amongst themselves, but a few of them link to a couple of the product pages.
How many separate articles does your site have, and what proportion of the total number of pages does this represent?
There are approximately 60 blog posts (articles) total. We have about 250 product pages. The articles get the majority of traffic (and the majority of inbound links).
(I used to have a directory and a coppermine gallery but removed them within a few weeks of getting hit by the March 23rd, 2012 Panda)
On the other hand, articles can sometimes support other pages, such as eCommerse pages, by helping to define what the site is about.
That's the thing: I am not sure that they are helping to define the site. Only VERY RARELY does a visitor who lands on an article ever end up purchasing anything. So there is a bid difference in the INTENT of the user to the article pages than to the eCommerce pages.
