Instagram Chief Says Post Share Rates Are Now a Key Driver of Reach

“More important than watch time or like and comment counts is send rates, [and] generally, I think the rate is more important than the count. So the number of sends per reach, the number of likes per reach, the number of comments per reach. But sends per reach correlate more, in my experience, with overall reach than anything else, because we are looking to help people discover content they want to connect with friends over, and so sends is a great proxy for that sort of connection over creativity.”
