Is it OK for SEO for a blog post to link to an ecommerce product page and vice versa?

Question

I am referring to an e-commerce environment, there is the blog part and the website part. I know that the blog should link to the product page, but is it a wise choice to link a product page back to one/or more other blog posts?

Lets say I sell clothes on my website and have recently launched a new t-shirt. I have a blog post that announces my new arrivals, with a link in the post going to this new t-shirt. On this t-shirt product page I have details regarding the t-shirt, like colour, size, type of material, type of stitch, etc.

Lets say a person is interested in the t-shirt and sees that the t-shirt is made of nylon and doesn't know what nylon is and would like to know more about nylon. So I was thinking of making the nylon text a link, when the user clicks on the nylon link, the user is able to read up more on nylon. Or lets say the t-shirt was stitched in a certain way, and the user wants to know more about this type of stitch, then a link takes the user to a page with more information on the type of stitch.

Now I have a question, should these information links link back to a blog post that was written about nylon or the type of stitch? Or should something more simpler be used like linking to a glossary page? My actual question is, if a blog post links to a product page, is it OK to link back from that product page to another blog post/blog posts?

Answer 1

From an seo perspective it's perfect ally ok even good, last weeks google webmasters hangout was telling us that cross linking is becoming increasingly more important, from a conversion point of view I would be very carful about driving traffic off a purchase page, perhaps a glossary in a lightbox could be a good alternative.
