> We saw app-wide impressions across all mobile platforms increase by 0.7%, and likes increase by 0.4%. This was driven by increases of impressions on all surfaces – for instance, “Explore Photos” impressions increased over 3%, and user profile scrolls increased 2.7%. I'm curious about this: was it A/B tested? Those figures are so small that they could just be seasonal or organic growth, the side effect of other things (events, weather, etc) that lead to increased engagement in general, and so on. The technical improvements look great, but attributing them directly to increased user engagement seems a little too fuzzy.
