Last quarter, PINS reported 459 million monthly active users, +37% YoY. This is more users than Twitter and Reddit, but fewer than Facebook, Instagram and Snapchat.
LikeFolio's Mention metric is a good post to gauge Pinterest usage...and in the last quarter, we recorded significant YoY growth: +68%.
This is impressive, considering the chart above captures English-speaking mentions. We know the international segment is Pinterest's major growth machine, now comprising ~79% of total users.
And Pinterest is only just beginning to monetize international users. On its last report, International ARPU (average revenue per user) was $0.35 vs. $5.94 ARPU domestically.
This revenue is driven by successful ad placements and conversions. So one hyper-focused lens we can use to understand ad impact is Shopping mentions -- purchasing a brand/product discovered on Pinterest.
