LinkedIn's Depth Score: One Meaningful Comment Now Outranks 15 Likes — What B2B Sales Teams Must Do Differently

LinkedIn has quietly retired the engagement velocity model. The platform no longer rewards a post for collecting ten likes in the first hour. It rewards a post for making someone pause for 47 seconds, click "see more," and then send it to a colleague. That shift — from fast to deep — is now embedded in a signal called the Depth Score, and it changes every assumption your sales team has made about what makes a LinkedIn post worth writing.

The Problem Your Team Has Not Named Yet

Most B2B sales teams are still optimising for the wrong metric. The instinct, reinforced by years of feed behaviour, is to post for immediate engagement: punchy hooks designed to harvest quick likes, content timed to hit the feed during peak network activity, and questions appended to every post to generate fast comment spikes. That playbook produced results until recently.

Under 360Brew — the 150-billion-parameter model now powering LinkedIn's content decisions — it is producing diminishing returns for most teams. The feed is being sorted by depth of engagement, not speed of it. Teams that have not adjusted are not just underperforming; they are actively training LinkedIn to distribute their content to a smaller and smaller audience over time.

The Insight: Depth Score and the 15x Weighting

LinkedIn's Depth Score tracks four signals that velocity-based ranking never measured:

Dwell time. How long does a reader pause on a post before scrolling past? A post that gets read takes longer than one that gets skimmed. Every additional second registers.

"See more" clicks. Does the content compel someone to expand the full body? This is a direct signal that the opening lines earned continued attention — one of the strongest indicators that the content has real substance.

Saves and DM shares. Does someone keep the post or forward it privately to a colleague? These signals indicate utility. The reader found the content worth returning to or worth sharing with someone specific.

Meaningful comments. Substantive replies that go beyond a word or a reaction emoji.

Of these, the comment weighting is the most critical shift to internalise. Meaningful comments now outweigh standard likes by a factor of 15 to 1. A post that generates 200 likes and no real discussion ranks below a post that generates 12 thoughtful replies from relevant professionals.

This is not a marginal difference. It is a structural reversal. Your team's content is no longer competing on the volume of reactions. It is competing on the quality of attention it earns.

What This Means in Practice

This changes what you should be measuring. Likes are the easiest metric to track and the least meaningful one under the current algorithm. The questions that now matter are different: Which posts prompt someone to write more than a sentence in response? Which posts get saved? Which ones get forwarded in a DM to a colleague the reader thinks should see it?

It also changes what your reps should write. A post optimised for dwell time is longer than one optimised for fast engagement. It contains a specific insight — a data point the reader had not encountered, an argument they can push back on, a practical framework they want to remember. Vague hooks and generic questions at the end are not enough.

Format matters here too. Carousels — PDF document posts — force dwell time structurally: a reader has to swipe through slides to complete the post. LinkedIn engagement data puts carousels at 6.60% average engagement, compared to roughly 2% for standard text posts. Under the Depth Score model, that format advantage compounds, because every slide viewed registers additional dwell time.

What to Do This Week

Audit your team's last 20 posts — sorted by comments, not likes. Identify which posts generated substantive replies. What made those different from the ones that collected reactions? That pattern is your new content brief.

Change the primary success metric. Replace engagement rate (likes + comments / impressions) with conversation rate: the proportion of posts that generated at least three meaningful comments. It is harder to game and a better predictor of pipeline value.

Brief your reps on dwell time. Posts that score well on Depth Score share a common characteristic: they take at least 30 seconds to read. That means a clear argument, supporting evidence, and a specific point of view — not a five-line observation with a generic question at the end.

Shift two posts per month per rep to carousel format. Design slides to contain actual information, not pulled quotes from the caption. Slide two should justify the time commitment to reach slide five. Every slide is an impression with a warm, engaged reader.

Make strategic commenting a formal team activity. When reps write substantive replies on prospects' posts, they generate Depth Score signals that benefit both posts — increasing the prospect's reach and associating the rep's name with quality engagement at precisely the right moment. This is the highest-ROI activity on LinkedIn that most B2B sales teams are ignoring entirely.

Social Sprint

Social Sprint gives Sales Managers visibility into which posts across their team are generating meaningful conversation — not just aggregate likes. When content strategy, posting cadence, and engagement behaviour are coordinated at team level, the Depth Score compounds across individuals rather than cancelling out.

Frequently Asked Questions

What is the LinkedIn Depth Score?

The LinkedIn Depth Score is a content ranking signal introduced under the 360Brew algorithm update. It measures how deeply users engage with a post — including how long they pause before scrolling (dwell time), whether they click to expand the full post, whether they save it or share it privately via DM, and the substance of their comments. Content that earns deep, sustained attention ranks higher than content that earns quick, shallow reactions.

How much more does a meaningful comment count versus a like on LinkedIn in 2026?

Under the current Depth Score model, a meaningful comment — a substantive reply rather than a single word or reaction emoji — is weighted approximately 15 times more than a standard like. A post with 10 thoughtful comments from relevant professionals can outrank a post with 150 likes from a broad but passive audience.

What content format performs best under the LinkedIn Depth Score algorithm?

Carousel posts (PDF documents) consistently produce the strongest results under dwell-time-based ranking, averaging 6.60% engagement compared to approximately 2% for text posts. Long-form posts with a specific argument or data point also outperform short hooks, because they require more time to read — and reading time is a direct input into the Depth Score calculation.

What should a Sales Manager change about their team's LinkedIn strategy because of the Depth Score?

Three shifts matter most: change the primary success metric from engagement rate to conversation rate (posts generating at least three substantive comments); brief reps to write longer, more specific content with a clear point of view rather than reaction-bait hooks; and make strategic commenting on prospects' content a formal, tracked team activity — it generates Depth Score signals for both posts and builds the rep's visible presence with exactly the right audience.
