where to publish my content? Blog product page?

[stitchlips]

I just joined this forum after reading a lengthy thread about publishing my content on my site first as opposed to eza. What a wealth of knowledge in that post.

Here is my situtation and I would like to know your thoughts.

I have a product site, it sells widgets. It is a product site listing products by category. Each product has it's own descrip and image but this site really has no verbage no meat only the products.

I am going to start writing articles about the products and want to know what would work best?

I have a product page for blue widgets and I have just written a lengthy article on blue widgets.

Should I
A. Post it to the product page above the products.
B. Post it to the product page below the products.
C. Make a blog under my root widgets.com/blog and post it there with a link back to my products page

Which method would be the best?

I have already written some articles for this site and I think I made a mistake by posting them to EZA first with links back to my site but no where on my site itself.

Thanks
