Drachsi:
Thanks, that makes a lot of sense. Do you mind if I use your info graphic? it explains exactly what is needed?

By all means use it.
The graphic shows that ALL other sites (blogs, microsites, social networks) inter-relate - so interlinking THEM is OK... but they must act as HARVESTING sites that all point somehow to the webshop. There are NO EXTERNAL LINKS on the webshop. Once people arrive at the webshop the objective is to FUNNEL THEM TO CHECKOUT. That is the only way you want them to leave the webshop.
Too many webshop owners provide links going OUT of the webshop to their other sites - this gives shoppers opportunities to leave the webshop without making a purchase.
Also, by making the OTHER SITES independent, you can leverage their functions to take advantage of SEO principles specific to their purpose - meaning you can get good SERPS via your entire web presence.
I do presentations and seminars on this and people who use these principles make good money out of their web presence.
