Your LinkedIn depth score is the reason your posts either reach 12,000 people or die at 400. Not your follower count. Not your posting time. Not whether you used a carousel or plain text. The Depth Score — LinkedIn's composite ranking metric introduced through the 360Brew algorithm update — now determines how far your content travels. And most ecommerce founders have never heard of it.
We ghostwrite for dozens of ecommerce founders. In the last 90 days, clients who optimized for Depth Score saw an average 3.2x increase in impressions compared to the prior quarter. One DTC brand founder went from 800 average impressions per post to 4,600 — without changing posting frequency. The difference was structural: we changed how the content held attention, not what it said.
Here's how the LinkedIn Depth Score works, what each component actually measures, and the specific changes ecommerce founders need to make right now.
What Is the LinkedIn Depth Score?
The LinkedIn Depth Score is a composite algorithm metric that measures how deeply users engage with your content — not just whether they interacted at all. It replaced the old engagement velocity model, where the number of likes and comments in the first 60 minutes determined distribution.
Under the old system, a post that collected 50 likes in 30 minutes from people who spent two seconds each would outperform a post that held 20 readers for 90 seconds each. That math has flipped.
The Depth Score evaluates five weighted signals:
- Dwell time — how long users spend reading or viewing your post
- Save rate — how many users bookmark your content for later
- Comment quality — whether comments spark substantive discussions or are single-word reactions
- Share patterns — whether users share privately via DM (high signal) or publicly repost with added context
- Scroll behavior — whether users stop, expand "see more," and stay, or scroll past within a second
Each signal feeds a composite score that accumulates over 24–48 hours. A high Depth Score triggers expanded distribution to second and third-degree connections. A low Depth Score caps your post at a fraction of your network.
The practical implication: a post with 15 likes and strong depth metrics will outreach a post with 150 likes and weak depth metrics. We've seen this happen repeatedly across client accounts.
How LinkedIn Depth Score Changed the Algorithm in 2026
The shift to Depth Score didn't happen overnight. LinkedIn's 360Brew system laid the infrastructure by replacing the legacy content-ranking stack with an AI-driven model trained on behavioral signals. The Depth Score is the output metric of that system.
Here's what changed operationally:
Before (engagement velocity model):
- Posts were scored primarily on reaction count in the first 60 minutes
- Engagement pods and comment-swapping inflated distribution
- Short, punchy, often shallow posts won because they collected fast reactions
- External links were penalized, but surface-level content was rewarded
Now (Depth Score model):
- Posts are scored on behavioral signals over 24–48 hours
- Fake engagement is detected and penalized — engagement pods now actively suppress reach
- Longer, more substantive content wins because it generates dwell time
- The algorithm reads for meaning, matching content to users based on topic relevance, not just network proximity
The data bears this out. Posts with 61+ seconds of dwell time average a 15.6% engagement rate. Posts with under 3 seconds of dwell time average 1.2%. That's a 13x difference in engagement driven entirely by how long people stay on the post.
For ecommerce founders, this means the "quick tip" post format that dominated in 2023–2024 is functionally dead. The algorithm now rewards the kind of content that teaches, provokes thought, or tells a story worth reading to the end.
The Five Depth Score Signals (And How Each One Is Weighted)
Not all Depth Score components are equal. Based on our data across client accounts and the publicly available research, here's how the signals rank in order of influence:
1. Dwell Time (Highest Weight)
Dwell time is the primary driver. LinkedIn measures exactly how long a user's viewport stays on your post — including whether they clicked "see more" to expand the full text.
Benchmarks for ecommerce founder posts:
- Under 3 seconds: post is effectively invisible to the algorithm
- 7–15 seconds: baseline; your post enters the standard distribution pool
- 30–60 seconds: strong signal; expanded distribution triggered
- 60+ seconds: top-tier signal; post reaches second and third-degree connections
What drives high dwell time:
- Posts that open with a specific, counterintuitive hook (not "5 tips for LinkedIn success")
- Content that uses white space and formatting to pull readers line by line
- Stories with narrative tension — the reader wants to know what happened
- Data or benchmarks the reader hasn't seen before
What kills dwell time:
- Generic openings that signal "you've read this before"
- Walls of text with no paragraph breaks
- Clickbait hooks that promise but don't deliver in the body
- Posts that reveal the punchline in the first two lines
We wrote a detailed breakdown of dwell time mechanics in our dwell time algorithm guide.
2. Save Rate (Second-Highest Weight)
When someone saves your post, LinkedIn interprets it as lasting reference value — this content is worth returning to. Saves now outweigh likes by roughly 6:1 in the algorithm's weighting.
Save rate benchmarks:
- Average ecommerce founder post: 0.3–0.5% save rate
- Strong performer: 1.0–2.0% save rate
- Top-tier (our best client posts): 2.5–4.0% save rate
Content types that drive saves:
- Frameworks with named steps (e.g., "The 3-Layer Pricing Communication Framework")
- Benchmark data or specific numbers people want to reference later
- Templates, checklists, and systems they can implement
- Contrarian takes backed by evidence that readers want to share in meetings
Content that doesn't get saved:
- Opinion posts without actionable substance
- Personal stories without a transferable lesson
- News commentary that expires in 48 hours
3. Comment Quality (Medium-High Weight)
The algorithm now evaluates the substance of comments, not just the count. A 50-word comment that adds a new perspective carries significantly more weight than 20 comments saying "Great post!" or a fire emoji.
High-quality comment signals:
- Comments over 20 words that reference specific points from the post
- Reply threads with 3+ exchanges between different users
- Comments that include personal experience or data
- Questions that generate additional discussion
Low-quality comment signals (can actually hurt your Depth Score):
- One-word reactions: "Agreed," "This," "Fire"
- Generic praise: "Great post!" "Love this!" "So true"
- Pod-style comments that arrive in clusters within the first 5 minutes
- Comments from accounts that comment identically on dozens of posts per day
This is why your commenting strategy matters as much as your posting strategy. When you leave substantive comments on other founders' posts, you're building their Depth Score and your own authority signal.
4. Private Shares (Medium Weight)
When someone sends your post to a colleague via LinkedIn DM, the algorithm treats it as a high-conviction endorsement. The reasoning: public reshares are often performative, but a private share means someone thought the content was valuable enough to recommend one-on-one.
How to trigger private shares:
- Include data or insights that would be relevant to a specific decision-maker ("Send this to your CMO")
- Write about problems that affect teams, not just individuals
- Create content that answers a question someone is likely being asked at work
- Post frameworks that are immediately usable in a meeting or strategy session
Tracking private shares: LinkedIn doesn't surface private share counts in standard analytics. You'll see the downstream effect in increased profile views and connection requests from people outside your network — the signature of a post that traveled via DM.
5. Scroll Behavior (Baseline Signal)
This is the gatekeeper signal. Before LinkedIn invests compute in evaluating the other four signals, it checks whether users stop scrolling when your post enters their viewport.
What triggers a scroll stop:
- A strong opening hook — the first two lines visible before "see more"
- Visual pattern interruption (a bold stat, a provocative question, an unexpected format)
- Posts from accounts the user has engaged with before (this is why consistency compounds)
If users scroll past without stopping, your post never enters Depth Score evaluation at all. It's functionally invisible. This is why strong hooks remain non-negotiable — they're the entry ticket to the Depth Score system.
What NOT to Do: Depth Score Killers for Ecommerce Founders
Understanding what suppresses your Depth Score is as important as knowing what boosts it. These are the patterns we've seen tank distribution for ecommerce founder accounts:
Engagement Bait
LinkedIn's 2026 Authenticity Update explicitly targets engagement bait. Posts that say "Comment YES if you agree," "Like = agree, comment = disagree," or "Tag someone who needs this" are now detected by the algorithm and penalized with reduced distribution.
This isn't a minor suppression. We've measured 60–80% reach drops on posts flagged as engagement bait compared to similar content from the same account without bait triggers.
Recycled Templates Without Substance
The algorithm reads for meaning now. A post that follows a viral template structure but contains generic, surface-level content gets flagged as low-value. LinkedIn's AI evaluates whether the post contributes new information or perspective to its topic cluster.
If your post about "3 things I learned scaling my ecommerce brand" reads identically to 500 other posts with the same structure and no unique insight, it scores poorly on Depth regardless of its format.
External Link Posts Without Context
Posts containing external links still face distribution headwinds. Zero-click content — where you deliver the full value natively inside the post — consistently outperforms link posts by 2–3x in our client data. If you must include a link, put it in the first comment rather than the post body, and make the post itself complete and self-contained.
Posting Frequency Over Posting Quality
Some founders think posting daily will accumulate Depth Score faster. It doesn't. The algorithm evaluates each post independently, and a weak post can actually suppress your next post's baseline distribution by training the algorithm to show your content to fewer people.
Three strong posts per week outperform seven mediocre ones. Every time.
Ignoring Negative Signals
LinkedIn tracks negative signals too — the "I don't want to see this" clicks, the hide-post actions, the unfollows. These actively lower your Depth Score baseline. One common trigger: posting about topics outside your established area of expertise. If you've built authority posting about DTC supply chain and you suddenly post generic motivational content, your existing audience sends negative signals that compress future reach.
How to Optimize Your LinkedIn Depth Score: The Ecommerce Founder Playbook
Here's the system we use with ghostwriting clients to maximize Depth Score across every post.
Step 1: Engineer the Hook for Scroll-Stop (First 2 Lines)
Your hook must accomplish one thing: stop the scroll and earn the "see more" click. For ecommerce founders, the highest-performing hook patterns are:
- Specific number + counterintuitive claim: "We spent $340K on Meta ads last quarter. LinkedIn generated more pipeline for $0."
- Problem acknowledgment: "Your LinkedIn posts get 200 views because the algorithm decided you're not worth showing. Here's what it's actually measuring."
- Pattern interrupt: "I've ghostwritten for 40 ecommerce founders. The ones who get results all do one thing the others don't."
Avoid hooks that feel templated or that start with "I" followed by a generic statement. The algorithm has seen millions of "I spent 10 years building my business and here's what I learned" posts and so has your audience.
Step 2: Structure for 60+ Seconds of Dwell Time
Once they click "see more," your post needs to hold attention for at least a minute. Structure techniques that work:
- White space: One to two sentences per paragraph. No exceptions.
- Progressive disclosure: Each paragraph should reveal something new. No repeating the same point in different words.
- Embedded tension: Pose a question or set up a contrast early, and don't resolve it until the second half of the post.
- Specificity: "We increased profile views by 600% in 60 days" holds attention longer than "we grew a lot on LinkedIn."
- Formatting: Use bold for key phrases, line breaks between ideas, and numbered lists when presenting sequential information.
A 1,200-word post that reads in 3 minutes will generate more Depth Score than a 200-word post that reads in 15 seconds — if the longer post maintains reader interest throughout. Length alone doesn't help; structured length does.
Step 3: Write for Saves, Not Just Reads
Every post should contain at least one element worth bookmarking:
- A framework with a name they can reference
- A set of specific benchmarks or numbers
- A step-by-step process they can implement
- A comparison or decision matrix for a choice they're facing
Think about what your reader would screenshot and send to their team. Build that into every post.
Step 4: Seed Comment Quality
Your post's comment section is part of its Depth Score. Don't leave it to chance.
First comment strategy: Drop a substantive first comment yourself — a question that invites specific responses, additional context that didn't fit the main post, or a follow-up data point.
Reply to every comment within the first 2 hours. Don't just say "Thanks!" — add value, ask a follow-up question, or share a related example. Each multi-reply thread adds depth signal.
Engage before you post: Spend 15–20 minutes commenting on posts in your network before publishing your own. This primes your profile's visibility and increases the chances that those people will see and engage with your post in return.
Step 5: Track the Right Metrics
Stop tracking likes as your primary metric. Here's the Depth Score dashboard we track for every client:
| Metric | Where to Find It | Target |
|---|---|---|
| Dwell time proxy | Impressions ÷ engagement rate trend | Increasing week over week |
| Save count | Post analytics | 1%+ save rate |
| Comment depth | Manual review | 30%+ comments over 15 words |
| Profile views | Profile analytics | Correlated spikes within 24hr of post |
| Connection requests | Network tab | 5+ per strong post |
| DM inquiries | Messaging | Track source attribution |
If your engagement benchmarks are strong on likes but weak on saves and meaningful comments, your Depth Score is underperforming relative to your actual reach potential.
LinkedIn Depth Score vs. the Old Engagement Velocity Model
Here's the practical difference in a side-by-side comparison:
| Factor | Old Model (Pre-2026) | Depth Score (2026) |
|---|---|---|
| Primary signal | Reaction count in first 60 min | Behavioral depth over 24–48 hours |
| Comment value | All comments weighted equally | Comment substance and thread depth matter |
| Saves | Minor signal | Second-highest weighted signal |
| External links | Penalized | Still penalized, but zero-click content rewarded |
| Engagement pods | Effective (gamed distribution) | Detected and penalized |
| Post length | Shorter often won | Longer content wins if structured for retention |
| Distribution window | First 2–4 hours critical | 24–48 hour accumulation period |
| Content type reward | Format-dependent | Value-dependent across all formats |
The shift rewards substance over speed. For ecommerce founders who have genuine expertise and real stories to tell, this is a structural advantage. You don't need viral tricks. You need a system for consistently producing content that holds attention and earns saves.
Why Depth Score Matters More for Ecommerce Founders Than Other Niches
Ecommerce founders have a specific advantage in the Depth Score era: your content naturally contains the elements the algorithm rewards.
You have real numbers. Revenue figures, growth rates, ad spend, conversion data, margin percentages — this is the kind of specificity that drives dwell time and saves. A SaaS marketing manager talking about "best practices" can't compete with a founder sharing "we cut CAC by 34% when we shifted $8K/month from Meta to LinkedIn content."
You have operational stories. Supply chain disasters, inventory miscalculations, hiring mistakes, product launch pivots — these are narratives with built-in tension that hold attention. The algorithm rewards content people read to the end, and founder war stories consistently deliver that.
You have a defined buyer. Whether you're selling to retailers, wholesale buyers, DTC customers, or potential acquirers, your content can be precise about who it serves. The algorithm matches content to users by topic relevance, and precise content clusters faster than generic advice.
You have proof. Case studies, before-and-after metrics, customer testimonials, revenue milestones — these are the save-worthy elements that boost Depth Score. You're not theorizing about what works. You're showing receipts.
The founders who underperform on LinkedIn almost always have the same problem: they think their expertise is "obvious" and doesn't warrant a post. The obvious-to-you problem is the single biggest obstacle to Depth Score optimization. What you consider routine is exactly what your audience finds valuable enough to save, share, and spend two minutes reading.
FAQ
How do I check my LinkedIn Depth Score?
LinkedIn doesn't surface a literal "Depth Score" number in your analytics dashboard. It's an internal algorithm metric. You track it through proxies: dwell time trends (visible on some post analytics), save counts, comment quality, profile view spikes after posting, and inbound connection requests. When these proxy metrics improve together, your Depth Score is climbing.
Does posting frequency affect Depth Score?
Not directly. Each post is scored independently. But posting weak content frequently can suppress your baseline distribution — the algorithm learns to show your content to fewer people if prior posts underperformed. Three high-depth posts per week is the sweet spot for most ecommerce founders.
Can a ghostwriter optimize for Depth Score?
Yes — this is exactly what a skilled LinkedIn ghostwriter does. The Depth Score era actually increases the value of ghostwriting because the algorithm rewards content quality, structure, and consistency — the three things a good ghostwriter brings that a time-strapped founder can't maintain alone. Strategic formatting, hook engineering, and save-triggering content structures are systematic skills, not inspiration.
How long does it take to improve Depth Score?
The algorithm needs roughly 60–90 days of consistent, high-depth content to recalibrate your account's baseline distribution tier. Clients who start from a suppressed baseline (low engagement, infrequent posting) typically see meaningful lift within 30 days, with compounding gains through month three.
Is Depth Score the same as dwell time?
No. Dwell time is one component of the Depth Score — the single highest-weighted component, but not the whole picture. Depth Score also incorporates saves, comment quality, share patterns, and scroll behavior. A post with high dwell time but zero saves and shallow comments will score lower than a post with strong dwell and strong saves.
Make the Algorithm Work for You
The LinkedIn Depth Score is the most founder-friendly algorithm change in the platform's history. It rewards exactly what ecommerce operators are best at: specificity, data, real stories, and operational expertise.
Three actions to start this week:
- Audit your last 10 posts for save rate. If you're below 1%, your content isn't structured for reference value. Add a framework, a benchmark, or a reusable template to every post.
- Restructure your hooks. Use the first two lines to stop the scroll with a specific number or counterintuitive claim. Kill every generic opening.
- Track comment quality, not comment count. If 80% of your comments are under five words, your engagement isn't helping your Depth Score. Seed better discussion with a first comment that asks a specific question.
The LinkedIn depth score rewards depth over drama, substance over speed, and expertise over entertainment. For ecommerce founders willing to build a content system around those principles, the reach is there. You just have to earn it one reader at a time.
