Instagram does not provide the means to push product links directly into Instagram and thus this is not part of the SNPT offering.
So, the only way to get your followers to click through to a product is via the profile link. The statistics we are getting show that brands who use their profile link to direct their Instagram followers to a "sandwich page" enjoy much higher sales conversion rates ranging between 3% to 8%. Those who direct their profile link to their home page or, a page not representative of their Instagram feed (as the source of the traffic) are much *less* successful with sales conversion rates ranging in the 0.5% - 1.2%.
