What CPM is on LinkedIn, and why it matters more than CTR
CPM is the cost of a thousand impressions. On LinkedIn it is the price of the audience you chose, in the month you chose to reach it, at the pressure you put on it. It is the one number that decides what you pay for everything else: across 181 accounts, 63% of the variance in cost per landing page click is CPM (r = +0.745, the strongest relationship in the study) and only 28% is click rate. You cannot creative your way out of a bad CPM. The four settings that move it are below; the hook, the format and the launch day are not among them.
All figures are from Kiin Labs' 2026 study unless labelled otherwise: 2,563 thought leader ad campaigns, 464 accounts, inside a $31M LinkedIn panel, B2B tech advertisers, US-weighted, 8 September 2025 to 7 September 2026, USD, Audience Network excluded, comparisons paired within account. ★★★ = 100+ advertisers within account; ★★ = 25–100; ★ = directional. Medians, not averages — the top 10% of accounts spend 64% of the money and would drag any average toward themselves.
The benchmark: median, good, exceptional
| Setup | Median CPM | Good (top quartile) | Exceptional (top decile) | Base |
|---|---|---|---|---|
| Thought leader ads, engagement objective | $65 | $36 | $21 | 212 accounts ★★★ |
| Thought leader ads (paired vs sponsored content) | $74.71 | — | — | paired ★★★ |
| Sponsored content, single image (same comparison) | $48.80 | — | — | paired ★★★ |
| Kiin operating range, single image company-page ad (UK) | £15–£30 average | <£15 strong | — | 200+ managed accounts |
A $65 CPM with a 0.46% landing page CTR is a $14.13 landing page click; the measured median is $14.71. Get the CPM to $36 with the same click rate and the click is $7.83 — roughly the top-quartile figure of $8.37. That is the arithmetic behind everything on this page.
CPM by month and quarter
March is the cheapest month on LinkedIn: CPM 84 against a typical month of 100. Early September is the most expensive so far at 107 (within account, provisional on eight days of September data, 86 accounts). December is not dead — CPM 104, engagement 105 ★★.
| Month (within account, typical month = 100) | CPM index | Engagement rate index | Cost per engagement index |
|---|---|---|---|
| March | 84 | 96 | 91 |
| February | 90 | 100 | 93 |
| December | 104 | 105 | 100 |
| August | 104 | 97 | 105 |
| September (first 8 days, provisional) | 107 | 92 | 116 [104–124] |
Quarter on quarter, same advertisers ★★★:
| Transition | CPM | Engagement rate | Cost per engagement | Cost per landing page click |
|---|---|---|---|---|
| Q4 → Q1 (n=63) | −16% [−27%, −3%] | −6% | −13% | −4% |
| Q1 → Q2 (n=153) | +30% [+22%, +44%] | −1% | +29% | +47% [+24%, +70%] |
| Q2 → Q3 (n=150) | +1% | −10% [−15%, −8%] | +8% | +11% |
Q1 indexes at 86, 14–16% under the typical quarter, with no January premium. Q1 to Q2 is the step: the same advertisers pay 30% more per thousand and 47% more per landing page click. Q2 to Q3 the price holds while engagement drops 10%. The full within-account range across the year is 27 points (84 to 107). The raw dataset CPM doubled over the year, from $45 to $90 — that is account mix, not the calendar, and it is why cross-account "CPM is rising" claims are usually measuring who joined the dataset.
What to do with it: front-load annual budgets into Q1, keep December on, and do not read a Q2 CPM increase as a performance problem — it is the auction. One year, one cycle; Q4 rests on 63–73 accounts.
CPM by day of the week
Sunday CPM is 4% under the campaign's typical day (96 [95–98]); Saturday is 1% under; landing page CTR is 9–10% higher on both weekend days (823 single-image engagement TLA campaigns, indexed within campaign ★★★).
| Serving day (campaign's typical day = 100) | CPM | Engagement rate | Landing page CTR | Cost per engagement |
|---|---|---|---|---|
| Monday–Friday | 100–102 | 98–102 | 97–100 | 99–101 |
| Saturday | 99 | 98 | 110 [106–113] | 100 |
| Sunday | 96 [95–98] | 100 | 109 [106–113] | 97 [96–98] |
Weekends carry 18% of spend. The landing page click-rate lift is the only day-of-week effect in the data that is not noise. Dayparting the weekend out — one of the most common "optimisations" in B2B accounts — removes the cheapest, highest-clicking 18% of delivery. There is no launch-day effect either: Friday–Sunday launch vs Tuesday–Thursday, cost per engagement −4% [−13%, +5%]; r = 0.00 within account.
CPM by audience size
Audience size is the setting that moves CPM most. On the brand awareness objective, CPM falls from $127.28 under 10,000 people to $29.46 at 100,000+ — a 74% drop. On engagement it stays in a $67–$111 band whatever the size, because engagement pays per reaction, not per impression (per-account medians, accounts running both objectives ★★).
| Audience size | n | CPM · engagement | CPM · brand awareness | Cost per engagement · Eng | Cost per engagement · BA | Reached per $1k · BA |
|---|---|---|---|---|---|---|
| Under 10,000 | 17 | $110.66 | $127.28 | $1.79 | $4.75 | 7,720 |
| 10,000–30,000 | 19 | $82.66 | $64.00 | $2.12 | $2.28 | 12,248 |
| 30,000–100,000 | 22 | $66.68 | $40.55 | $2.20 | $2.15 | 21,117 |
| 100,000+ | 16 | $104.77 | $29.46 | $1.89 | $1.06 | 28,114 |
Cost per landing page click by audience size tells the same story from the other end: flat at $15–$18 from 1,000 to 150,000 people, then $14.20 at 200,000, $10.61 at 300,000, $8–$9 over a million. The 5,000–15,000 zone runs $18–$25 because a normal $30–$50 a day overspends it. Landing page CTR is flat across the whole range (0.41–0.59%): size changes what an impression costs, not whether people click ★★★.
The cost to reach half an audience, modelled from 1.39 impressions per member at each band's observed CPM: $448 for 3,400 people, $1,752 for 9,800, $3,544 for 27,000, $9,740 for 81,000, $15,832 for 260,000. Cost per thousand reached rises with depth: $122 at 0–5% penetration, $500 at 35–50%.
CPM by objective: engagement vs brand awareness
Brand awareness buys the cheaper impression: on a cold audience of 30,000+, CPM is 59% lower and reach 184% higher than engagement (n=18 ★★). Overall, brand awareness reaches 77% more people per dollar. But the cheaper impression only helps if it lands on someone new: under 10,000 people, brand awareness CPM is 13% higher and cost per engagement is $4.75 against $1.79, because there is nobody extra to reach.
Neither objective is cheaper per landing page click — $17.24 vs $17.22 within the same 36 accounts. The rule Kiin runs: brand awareness on cold audiences of 30,000 or more, single image, CPM bid; engagement on retargeting pools, uploaded lists, anything under 10,000, video, and anything that needs to be acted on. On a retargeting pool, brand awareness costs +51% to +90% per engagement with CPM +14%. On video, cost per engagement +99%. The full decision is in engagement vs brand awareness.
CPM by format: thought leader ads vs sponsored content
Thought leader ads cost $74.71 per thousand against $48.80 for company-page sponsored content in the paired comparison — and the two formats have identical landing page CTR, 0.449% vs 0.441% ★★★. The entire thought leader ad premium is CPM. It buys engagement (several times higher), dwell and being read; it does not buy a cheaper click. If the click is the job, single image sponsored content on the website visits objective is the cheapest landing page click on LinkedIn at $11.75 median.
Video thought leader ads do not have a CPM advantage that survives the click: $32.34 per landing page click against $13.51 for single image. Company-page video on the website visits objective is fine at $12.01. Format-by-format cost per click is on LinkedIn Ads benchmarks 2026.
CPM by budget pressure — the elbow at $2
The right unit for budget is dollars per day per 1,000 targeted members. It predicts CPM at r = +0.50, and CPM predicts cost per landing page click at r = +0.745 (940 campaigns, 82,700 campaign-days ★★★).
| $ per day per 1,000 members | Typical audience | CPM | Cost per landing page click |
|---|---|---|---|
| Under $0.50 | 130,000 | $39.57 | $8.07 |
| $0.50–$1 | 40,500 | $62.86 | $12.57 |
| $1–$2 | 26,000 | $78.10 | $16.19 |
| $2–$5 | 11,000 | $82.66 | $15.69 |
| $5–$10 | 5,000 | $121.81 | $22.00 |
| $10+ | 3,200 | $121–$128 | $18–$20 |
Cost per landing page click doubles between $0.50 and $2 a day per 1,000 members. That is the elbow. The same $50 a day costs $35.04 per landing page click on an audience under 10,000 and $13.59 on one over 100,000. Within a single campaign, a day at 0.5–0.8× normal spend buys clicks 17% cheaper; a day at 3× buys them 66% dearer; doubling daily spend costs 26% more per click and returns 59% more clicks (cost per click ∝ spend0.33). Kiin sizes budget to the audience: if a campaign needs more spend, widen the audience before raising the daily budget.
CPM and the bid
The highest-bid campaign in an account pays 59% more CPM [+19%, +104%] and 128% more per engagement than the lowest, and gets 32% less engagement rate (n=67, within account, not audience-matched ★★). Bid to cost per engagement correlates at r = +0.70, positive in 85% of 78 accounts.
Bid type does not matter. CPC vs CPM across 49 accounts running both: every confidence interval spans zero at every audience size; audience-matched within account, −13% [−42%, +32%]. Manual vs max-clicks: no difference. Enhanced conversion optimisation: cost per engagement +56% [+23%, +148%], engagement rate −34%, worse in 76–82% of accounts — avoid.
On CPM bidding, engagement has zero effect on the CPM you pay: r = −0.02 over 9,077 campaign-days. The most-engaging creative costs +1% per thousand vs the least. The idea that LinkedIn rewards engaging creative with cheaper impressions is not in the data. On CPC bidding the opposite happens — the most-engaging creative costs +101% per 1,000 impressions, because you are billed for every reaction. Kiin bids CPM on engagement objectives for that reason, keeps bids at $3 or under, and turns Audience Network off (3.7× the click rate, 9× worse conversion).
CPM by seniority, function and company size
Reaching the C-suite costs nothing extra per click. Cost per landing page click runs $12.51–$13.47 across every seniority tier, while engagement rises with seniority: senior IC 3.46%, manager 3.88%, director 4.33%, VP 4.31%, CXO 4.42%. Campaigns with no seniority filter pay the most, $16.88 per landing page click, and they are 79% of spend ★★.
Narrow is cheaper. One job function: $12.51 per landing page click at $49 CPM. Seven or more functions: $19.12 at $66 CPM. Two to three seniority tiers: $0.98 per engagement at $40 CPM; no seniority filter: $1.90 at $78. By function, entrepreneurship is the cheapest click ($9.60), HR the most engaged (5.52%); technical and operational functions cost 50–100% more to reach (IT $19.21, QA $22.17). By company size, SMB engages 40% more than enterprise — 5.93% at 2–10 employees, 3.58% at 10,001+ — monotonic through every band.
CPM on uploaded lists and retargeting
An uploaded list costs 11% more CPM than cold and performs like cold: every paired interval spans zero (n=43 ★★). A list costs $340 per 1,000 people reached against $159 cold — 2.1×. True retargeting of website visitors and ad engagers costs +58% CPM and buys +25% engagement and +20% dwell for it; cost per click is a wash (+14%, spanning zero). Of 1,927 campaigns, 48% run on uploaded lists on the assumption that they are warm. They are not.
The big spenders' CPM problem is this one: the top 10% of accounts run 81% of their money on lists and retargeting and pay $105.79 CPM; the bottom half run 0% on lists and pay $46.87.
CPM and scale: big spenders pay more
| Spend tier (engagement single-image TLAs) | CPM | Cost per engagement | Cost per landing page click | Spend on lists / retargeting |
|---|---|---|---|---|
| Top 10% of accounts | $105.79 | $2.18 | $20.18 | 81% |
| 10–25% | $80.45 | $1.95 | $19.80 | 99% |
| 25–50% | $77.32 | $1.46 | $13.24 | 37% |
| Bottom 50% | $46.87 | $1.11 | $10.53 | 0% |
Scale does not get cheaper on LinkedIn. Even holding the advertiser constant, high-spend months cost 18% more CPM [+11%, +23%] and 15% more per landing page click than low-spend months (n=176 ★★★). Half of all thought leader ad spend comes from 23 accounts; any benchmark that averages across accounts is describing them.
What does not move CPM
- Engagement rate, on CPM bidding: r = −0.02.
- Bid type (CPC vs CPM): every interval spans zero.
- Hook, post length, link: +2% engagement without a link, nothing on price.
- Boosted vs purpose-built: +3% engagement, interval spans zero, cost per click −12% not significant.
- Launch day and hour: r = 0.00.
- Time live: CPM flat over eight weeks. Fatigue is a frequency effect (engagement −9% at 1× cumulative, −22% at 5×), not a price effect.
UK CPM in pounds
UK B2B single image CPMs typically run £25–£60; Kiin's operating range for a company-page single image ad is £15–£30 average and under £15 strong. The UK dynamic is the opposite of the US: audiences of 15,000–40,000 sit in the budget-pressure zone above, so the UK CPM problem is usually a spend-per-member problem, not an auction problem. Cost per landing page click runs £6–£40 by format. Full GBP ranges are on LinkedIn Ads cost UK.
How to reduce your LinkedIn CPM
In the order the data supports, each worth 1.6–2.2× on cost per landing page click on its own:
- Widen the audience past 30,000. Brand awareness CPM falls 74% from under 10k to 100k+; landing page CTR does not change.
- Keep budget pressure under $2 a day per 1,000 members. The click doubles between $0.50 and $2. Widen before you raise.
- Put at least half the spend on cold targeting. A list is cold with an 11% CPM premium and 2.1× the cost per person reached.
- Bid $3 or under, manually, CPM on engagement. The highest bid in an account pays +59% CPM and +128% per engagement.
- Add a seniority filter and one or two functions. Two to three tiers: $40 CPM. No filter: $78.
- Use brand awareness on cold 30k+ audiences. −59% CPM, +184% reach, same cost per click.
- Front-load into Q1, leave weekends on, keep December. March 84, Q2 +30%, Sunday 96.
- Audience Network off.
An account with none of the first four ticked pays $25.46 per landing page click; with all four, $6.42. This is the first thing Kiin checks on any account it takes over — the scope is on LinkedIn Ads management — and creative comes after.
