Welcome to the Q&A Forum

I have a small client with a website PR2, 268 links from 21 root domains with mozTrusts 5.5, MozRank 4.5 However whenever I check in google for the amount of link:  Google always give the response none.  My client has a blog and many articles on the blog.   However they have submitted their blog article every time to article directories as well, plain and simle creating duplicate and content.  Is this the reason why their link: is coming up as none?  Is there something to correct the situation?

My client has a website with 160 pages specific to each storefront location.  Their strategy was to not have any links to the homepage so they cannot leave that storefront site.  I feel it makes sense to create a breadcrumb navigation so the user doesn't have to retype in the url to get back (and provides some internal link juice as well).  Has anybody ever came across the same situation or have done testing to know what the bounce rate is?  Or possibly pose the right response to convince my client they should in fact have a breadcrumb navigation?
