Is this the actual strategy? (for bringing traffic to an ecommerce)

I've been pinning for a few days and it's clear that my shop isn't going to get flooded with traffic from Pinterest any time soon… This going to be a medium to long term strategy thing (fk..)
Is the way to build traffic from Pinterest like a long tail strategy?
I've made a graph to be clear.
If any experienced guys out there can confirm this is correct, that would be cool.
