A highly successful affiliate, whose progress I've been watching for years, now puts his main traffic-building focus on Pinterest.
I'm not saying Pinterest is the only reason for his traffic - far from it - but it's playing a large role in his phenomenal traffic.
This is a guy who - at his best time of the year - gets nearly 200,000 visitors a DAY.
He's not selling a product, most of his revenue comes from AdSense, and he's doing well enough to have one full-time helper and a two part-timers. So I reckon it's worth while watching what he does.
Some niches are going to be more appropriate than others for promoting on Pinterest.
His success has certainly got me thinking of ways to add more Pinterest-worthy images to my niche sites.
