The Head of Instagram since 2018, who also oversees Threads and previously led Facebook's News Feed. He is known for publicly explaining Instagram's ranking signals.

What is sends per reach?

Shares into DMs divided by accounts reached. Mosseri calls it one of the most important signals for expanding reach, because a share is a stronger endorsement than a like or comment.

Why does he value shares over likes?

A like is passive; sending a post to a friend is an active recommendation, so Instagram treats it as the strongest signal that content deserves wider distribution, especially to non-followers.

Who he is, in plain terms

Adam Mosseri has led Instagram since 2018 and also oversees Threads; earlier he ran Facebook's News Feed. What sets him apart from other platform executives is candor — through short videos, AMAs, and posts he explains, in public, the signals Instagram weighs when it decides who sees a piece of content. For people who make and buy social, that running commentary is the closest thing to a rulebook the platform offers.

The idea he's known for: sends per reach

Mosseri's most-quoted point is that sends per reach — how often a post is shared into DMs, divided by how many accounts saw it — is among the strongest signals for growing an audience. A like is passive; a send is an active recommendation that puts the sender's credibility on the line, so Instagram treats it as the highest-confidence vote that content deserves wider distribution, especially to non-followers.

In his words. “The most important thing you can do is make content people want to send to a friend. A send is worth far more than a like — it's a real recommendation, person to person.” — Adam Mosseri, reflecting his public statements on Instagram ranking (2024–2025).

Why he matters to marketers

His framing moves the goal from “content people like” to “content people send.” Reach is now earned by being worth forwarding — which raises the bar on creative and rewards usefulness, surprise, and identity over polish. The same principle lowers paid distribution cost: shareable creative spreads more cheaply, so sends per reach is a distribution discount, not a soft brand metric. It is the data point behind RGM's long-held view that the best distribution is earned.

Worked example. A meal-kit brand swaps “Our new menu is here” for “Send this to the friend who says they can't cook.” Same product, but the second has a recipient built in — the send rate triples and the post reaches thousands of non-followers. Nothing about the food changed; the brief changed from admire this to forward this.

Failure modes to watch. Chasing sends with “tag a friend” bait (it games the signal and trains the algorithm on noise); reporting likes while ignoring the share rate; and treating it as organic-only when the same creative also lowers paid costs.
