Why DM Shares Count 3 to 5x More Than Likes on Instagram in 2026

Back in May 2024, Adam Mosseri already stated that the DM send rate weighs more heavily than the number of likes and comments in a post's distribution ("sends per reach correlate more, in my experience, with overall reach than anything else," Social Media Today, 2024). Two years later, this signal remains largely underused by brands.

Most accounts still optimize for visible engagement, likes and comments first, while the Instagram algorithm increasingly favors what gets shared privately. That gap is costly in terms of organic reach, especially when it comes to reaching audiences beyond your current followers.

This article details what Meta has actually confirmed about the weight of DM shares, how this signal is measured, which formats generate it best, and how to adjust your content calendar accordingly.

Why has private message sharing become Instagram's number-one algorithm signal?

DM sends weigh more than likes and comments in the distribution of Instagram posts, according to Adam Mosseri himself: "sends per reach correlate more [...] with overall reach than anything else" (Social Media Today, 2024). This finding now shapes how Instagram decides who sees your content beyond your followers.

A ratio of 3 to 5 times the weight of a like is widely cited by marketing analysts to quantify this effect. To be clear: Meta has never confirmed this exact figure, nor published an official methodology on the subject. What is confirmed, however, is the hierarchy itself. Sharing outweighs passive engagement.

This hierarchy doesn't apply uniformly everywhere. For your existing followers, likes still carry real weight in feed ranking. It's mainly for discovery, via Explore and Reels suggested to accounts that don't yet follow you, that DM sharing becomes decisive.

Why does Instagram make this choice? Mosseri explains it through the mission he assigns to the platform: "we focus more on sends primarily because our whole hope is to inspire creativity that brings people together" (Shopify Blog, 2025). Sending a DM requires thinking of a specific person and actively passing the content along to them, a more engaged gesture than a simple like.

How does Instagram measure and weight shares?

Instagram calculates a "sends per reach" ratio, the number of sends divided by a post's total reach, to assess its ability to travel beyond its initial audience (Social Media Today, 2024). The higher this ratio, the more organic distribution the post gains.

Three types of sharing exist on Instagram: sending directly via private message, resharing to a story, and external sharing to other apps. Mosseri specified that the DM send remains the most telling of the three, noting that the volume of content sent via private message already exceeds what's posted to stories and feed combined (Armchair Expert with Dax Shepard podcast, 2026).

This precise ratio doesn't appear as such in the Instagram Insights available to professional accounts. You can still track its evolution indirectly via the "Shares" metric shown under each post and Reel, by manually dividing it by the total reach shown in your stats.

How should you interpret a change in this ratio from one post to the next? A rise signals content considered worth passing on to someone in particular. A drop, conversely, indicates content that holds attention without triggering a sharing action.

Designing "shareable" content: concrete levers

Shareable content triggers a reaction the audience wants to pass on to a specific person: surprise, strong identification, or directly actionable information (Shopify Blog, 2025). Three levers let you provoke this reaction consistently.

The first lever relies on the actionable tip. A post that directly answers a need a friend or relative recently expressed gets passed along naturally, with a "you have to see this" logic. The second lever plays on identification and relatable humor: content where the audience recognizes itself so strongly that it wants to tag someone in the comments or send it via DM.

The third lever relies on surprising or counter-intuitive data. A number that challenges a widespread belief prompts people to send it to back up a point in an ongoing conversation. These three levers share one thing in common: they require thinking of a specific person even before publishing, not just a generic audience.

Structurally, the trigger needs to appear within the first two seconds of a Reel or on the very first image of a carousel. An audience that hesitates too long before understanding the content's value won't follow through to the sharing action.

Carousels or Reels: which format generates the most DM shares?

Meta doesn't publish an official breakdown of DM shares by format. The 2026 engagement trends still offer useful clues: Reels are the only format whose engagement rate grew over the year, up 24.76% year-over-year, while single-image posts declined across every metric (Metricool, 2026 study).

Carousels, for their part, generate around 9 times more saves and 4 times more interactions than a single-image post (Metricool, 2026 study). High save behavior signals content deemed worth revisiting, a quality that often overlaps with the urge to share it.

In the absence of public data broken down specifically by format for DM sharing, the most reliable reading is as follows. Reels capture attention and lend themselves to impulsive sharing between friends and family. Informative carousels get shared more in a "value to revisit later" logic.

Single-image posts, meanwhile, declined across every engagement metric in 2026: reach down 21.96%, interactions down 25.41%, overall engagement down 45.98% year-over-year (Metricool, 2026 study). This format remains the least likely to generate DM sends this year.

Other rising signals: engagement depth and saves

Saves are rising as a signal of perceived quality, particularly on carousels, which generate 9 times more of them than a single-image post (Metricool, 2026 study). This signal complements, without replacing, the weight of DM shares in distribution.

Average Reels watch time has nearly doubled in a year, reaching 8.5 seconds in 2026 (Metricool, 2026 study). This growth in engagement depth, beyond the simple like, confirms that Instagram values signals that require real investment from the audience: staying to watch, saving, sending.

Be wary of overly precise rankings circulating online, like "saves now weigh 3 times more than likes": no primary Meta source confirms this kind of ratio to date, despite its recurring attribution to studies that don't actually mention it. What is established is the underlying trend. Passive signals like the like are losing ground to signals that require an active gesture.

What does this change for your content calendar?

If DM sharing weighs more than the like in 2026 distribution, your content calendar needs to include content designed specifically to be sent, not just liked. In practice, that means reserving part of your posts for an explicit sharing trigger rather than a like-driven goal.

Three practical adjustments follow from this. First, systematically test your opening hooks and measure the shares-to-reach ratio post by post, rather than just the like count. Second, set aside one or two formats per week specifically designed for sharing: an actionable tip or a surprising statistic upfront.

Finally, track this ratio over time to identify what actually resonates with your audience. A post with few likes but a high sharing ratio often deserves more attention than a post that looks viral but is rarely sent.

Does this shift in priorities mean rebuilding your entire content strategy? No. It mainly means measuring a metric that most accounts still ignore, and gradually adjusting your format mix accordingly.

Frequently asked questions about DM shares and the Instagram algorithm

Here are the most commonly asked questions about this signal and its real weight in 2026 distribution.

Do DM shares really count more than likes on Instagram?

Yes, according to Adam Mosseri himself: the ratio of sends to reach correlates most strongly with a post's overall reach, more than likes or comments (Social Media Today, 2024). The exact "3 to 5 times" ratio circulates widely but has never been confirmed by an official Meta source.

How do I know if my content has a good share rate on Instagram?

Divide the number of shares shown under a post by its total reach, visible in the native stats for professional accounts. A ratio that improves from one post to the next indicates content your audience deems shareable, regardless of its like count.

Do Reels generate more DM shares than carousels?

Meta doesn't publish this breakdown by format. Reels are the only format showing an engagement increase in 2026, up 24.76% year-over-year, while carousels generate 9 times more saves than a single-image post (Metricool, 2026 study), a related but distinct signal from sharing.

Should I stop chasing likes on Instagram in 2026?

No. Likes still carry weight for distribution among your existing followers. They simply count less than DM sharing for reaching new audiences via Explore and suggested Reels, where the sends-per-reach ratio dominates (Social Media Today, 2024).

How can I increase DM shares on my Instagram posts?

Design content that sparks the urge to send it to a specific person: an actionable tip, a surprising data point, or content a friend or relative will strongly identify with. Mosseri explicitly ties this behavior to Instagram's goal of building connection between users (Shopify Blog, 2025).
