If your LinkedIn CTR is flat and CPL is creeping up, the constraint usually isn’t “more budget.” It’s attention. And LinkedIn’s new dwell time metric is one of the first platform signals that tries to measure it directly.
Here’s the uncomfortable part: what looks like “good performance” on a dashboard can be mostly a measurement artifact. Clicks are sparse in B2B. Video views are defined differently depending on paid vs. organic. Dwell time—average time someone spends on your ad before scrolling or clicking—gives a second angle on whether the creative is earning consideration at all.
AJ Wilcox, on The LinkedIn Ads Show, framed dwell time as an attention metric: average time viewers spend on an ad before scrolling or clicking. LinkedIn calculates it based on impressions where the ad has over 50% visibility, and it applies across placements like the newsfeed, LinkedIn Audience Network, and connected TV. That “50% visibility” detail matters. It’s not measuring time an ad exists somewhere on a page; it’s measuring time when it’s actually in view.

Why dwell time matters right now (and why the averages look weird)
Dwell time is rolling out in Campaign Manager (and not all accounts have it yet), and it’s currently not exportable to CSV or through the API. That limitation is annoying operationally. It’s also a tell: LinkedIn is still deciding how much they want this metric to shape advertiser behavior. (Source: AJ Wilcox, The LinkedIn Ads Show, July 19, 2024.)
But the timing makes sense. LinkedIn is shipping new inventory types—like sponsoring newsletters (including company and individual newsletters) and connected TV updates like frequency control—while advertisers are fighting creative fatigue and shrinking attention spans. A metric that approximates “did a human actually look at this?” becomes more useful when clicks become less representative of value.
And yes, the averages look strange at first glance. Newsfeed ads average 2.68 seconds, while LinkedIn Audience Network averages 17.5 seconds and connected TV averages 23.55 seconds. That’s not a rounding error. It’s a reminder that placement changes behavior. (Source: AJ Wilcox, The LinkedIn Ads Show, July 19, 2024.)
Hold that thought. The benchmark isn’t “higher is always better.” The benchmark is “higher than your own baseline for this exact format, objective, and audience.”
What “good” looks like: benchmark dwell time by format and objective
Start with the platform-level benchmarks Wilcox shared, then narrow to your situation. Directional, not definitive. Still useful.
Placement benchmarks: Newsfeed ads averaged 2.68 seconds. LinkedIn Audience Network ads averaged 17.5 seconds. Connected TV averaged 23.55 seconds. (Source: AJ Wilcox, The LinkedIn Ads Show, July 19, 2024.)
Format benchmarks: Single image ads averaged 4.76 seconds. Document ads averaged 2.74 seconds. Thought Leader Ads were cited in the 3–5 second range. (Source: AJ Wilcox, The LinkedIn Ads Show, July 19, 2024.)
Objective benchmarks: Job applicant objectives had the highest dwell time. Video views tended to drive higher dwell time. Lead generation was the lowest, around 2.7 seconds. (Source: AJ Wilcox, The LinkedIn Ads Show, July 19, 2024.)
That last line creates a useful tension: lead gen is often the KPI everyone cares about, yet it’s the objective where people linger the least. This doesn’t mean lead gen is “bad.” It means lead gen ads are usually engineered to extract an action quickly, and the platform may optimize delivery toward click-prone behavior that doesn’t require much reading.
So the correct benchmark question isn’t “Is 2.7 seconds good?” It’s: “For lead gen in the newsfeed, are we earning more attention than the baseline without breaking CPL?” Two metrics. One trade-off.
The one move: build a dwell-time baseline and use it as a leading indicator
If you only change one thing, change this: treat dwell time as a creative signal, not a performance KPI.
Clicks and leads are downstream. Dwell time sits earlier in the chain, closer to “did the message land.” Used correctly, it helps you diagnose whether a CTR drop is a targeting issue, a saturation issue, or simply creative that isn’t getting processed.
Step 1 — Setup (create a fair baseline): In Campaign Manager, pull dwell time from the engagement or video columns (depending on what LinkedIn exposes in your account). Record it weekly by campaign objective and ad format. Don’t blend formats. Don’t blend placements. (Source: AJ Wilcox, The LinkedIn Ads Show, July 19, 2024.)
Step 2 — Launch (run a controlled creative refresh): Keep targeting, bid strategy, and budget stable. Swap only the creative variable you want to test (hook, first line, visual, headline). This is the part most teams skip, then wonder why nothing is attributable.
Step 3 — Readout (tie it to outcomes, carefully): Compare dwell time deltas to CTR and CPL deltas. Dwell time rising while CTR stays flat can still be a win if qualified pipeline improves later—but don’t claim causality from the dashboard alone. Treat it as directional evidence that the ad is earning consideration.
Step 4 — Next test (guard against creative fatigue): When dwell time decays week-over-week while spend stays steady, assume fatigue until proven otherwise. On CTV specifically, LinkedIn has announced frequency control to manage exposure and viewer fatigue—so the platform is explicitly acknowledging this problem. (Source: AJ Wilcox, The LinkedIn Ads Show, July 19, 2024.)
The hypothesis (make it falsifiable)
If the team refreshes the first-line hook and primary visual while keeping audience, budget, and objective constant, then dwell time will increase versus the prior creative baseline, because the ad will earn more initial attention before a scroll—especially in the newsfeed where the average is only 2.68 seconds. (Benchmark source: AJ Wilcox, The LinkedIn Ads Show, July 19, 2024.)
Success metrics and guardrails
Primary metric: Dwell time (by format + objective).
Secondary metrics: CTR and CPL (or cost per lead for lead gen objective). Keep an eye on frequency as a fatigue proxy, especially if you’re not using CTV frequency controls.
Stop-loss threshold: If CPL worsens materially while dwell time rises, the creative may be attracting attention from the wrong segment (or creating curiosity without intent). Pause the test and revisit message-market fit before touching bids.
What to measure (and what not to over-interpret)
Use dwell time to answer one operational question: “Is this ad being read or ignored?” It’s a leading indicator, not a revenue metric.
Also be aware of definition mismatches around video. Wilcox noted that paid video ads count a view after 2 seconds, while organic video views require 3 seconds. That gap alone can distort creative readouts if the team compares paid performance to organic engagement without adjusting expectations. (Source: AJ Wilcox, The LinkedIn Ads Show, July 19, 2024.)
When this is wrong: If you’re running placements where longer dwell time is structurally “baked in” (Audience Network and CTV), comparing those numbers to newsfeed benchmarks will send you chasing the wrong improvement. The goal isn’t to make a newsfeed ad behave like a TV spot. It won’t.
The goal is simpler: build a baseline for your motion, then use dwell time as an early warning system for creative decay—before CTR and CPL make the problem expensive.
Newsfeed averages 2.68 seconds. That’s the circle to close. In a channel where attention is measured in single-digit seconds, the practical job is to earn just a little more of it—consistently, repeatably, and without pretending a dashboard screenshot is incrementality.
