In order to receive more traffic from Pinterest, you should develop your profile. Don't pin only photos of your products or business. Share other content also so the people can see that you are not only looking for profit but you are trying to contribute to the community.
It's the gold mine of traffic, if you know how to do it... I'm currently doing a pinterest campaign for a client and he is making $xx from adsense/day
Same here, all whitehat you need to get the right tools or people to get it done. Doesn't cost a fortune and it runs smoothly
