TikTok and LinkedIn sell the same outcome — a B2B buyer who books a meeting. TikTok sells cheap attention: short vertical video in a feed built for discovery, priced by an auction where bids are measured in cents per click. LinkedIn sells expensive precision: the same buyer reached by job title, company and seniority, priced by an auction where a single click costs more than a TikTok lunch. Neither publishes an average CPC or CPM, so this playbook prices both from their own published minimums, then works the $1,000, $5,000 and $10,000 months with one stated set of planning assumptions.
What each platform actually sells
Both run second-price auctions, charging for impressions, clicks and, on LinkedIn, message sends. TikTok Ads Manager sells In-Feed Ads in the For You feed, Spark Ads that boost an existing organic post, TopView as the first video on open, plus Catalog Ads, Shop Ads and LIVE Shopping Ads. Its guide puts In-Feed Ads at up to 60 seconds, with 21 to 34 seconds best. LinkedIn Campaign Manager sells Sponsored Content in the feed — single image, video, carousel — Message Ads and Conversation Ads in the inbox, Dynamic Ads, and Text Ads on the desktop right rail. LinkedIn charges per send on Message Ads, per click on action campaigns and per impression on awareness campaigns, and its auction rewards engagement, so an advertiser can win without the highest bid.
The structural difference is targeting. TikTok recommends starting broad: its budgeting page warns that narrow targeting can hurt performance. LinkedIn is built the other way: more than 20 audience attribute categories, including company size, skills, job title and seniority, with location required on every campaign. TikTok finds buyers by interest and behaviour; LinkedIn finds them by the job title on their profile.
TikTok: the published floors, and what they force
TikTok Ads Manager help states the minimums plainly: campaign budgets, daily or total, must exceed $50. Ad group daily budgets must exceed $20, and lifetime budgets are $20 times scheduled days — 31 days is $620. Once published, the budget type cannot be changed, so pick it before launch.
TikTok also publishes recommendations: a $30 minimum daily ad group budget for web conversion in North America and EMEA, $20 for APAC, and a 7-to-14-day run to read results. Its video guide suggests testing creative variations on $20 to $30 a day, then scaling the strongest performers. Bidding is Lowest Cost, which spends the budget to maximise results, or Cost Cap, which caps the average cost per result.
TopView is the exception to everything cheap about TikTok: the first video on open, a 3-second full-screen takeover with sound on, bought on a CPM basis and available only to qualified customers through a sales representative. TikTok advises booking at least 60 days ahead for campaigns buying 100% of impressions on a chosen date. It is a launch-day instrument, not a lead-generation channel.
LinkedIn: the published floors, and the audience that eats them
LinkedIn states its minimums: the minimum daily budget is $10, for any ad format, and the minimum lifetime budget for a new, inactive campaign is $100. Once it launches, the lifetime minimum becomes $10 times the days scheduled. LinkedIn suggests $25 a day for new advertisers and $50 to $100 for existing ones.
The $10 floor is a technical minimum, not a workable budget: at the planning CPC of $9.39, $10 a day buys about one click a day. Sponsored Content carries Lead Gen Forms, which collect a lead inside LinkedIn. Message Ads bill per send and put one message with one call to action in the inbox; Conversation Ads offer up to five buttons so the recipient picks a path. Dynamic Ads personalise creative from profile data, and Text Ads are the cheapest, lowest-performing format. Every standard format requires a company Page.
One figure in this playbook is not vendor-verified this cycle and is labelled as such: LinkedIn's 300-member audience floor. Current 2026 guides quote LinkedIn's audience-size help page: the minimum audience size for an ad set is 300 member accounts, with 50,000 suggested to drive results and 300,000 for Sponsored Content and Sponsored Messaging. Our editorial analysis could not open that help page directly this cycle, so treat 300 as reported, not verified. A list of 40 companies with two job titles each will often fall below it once location is applied; widen seniority or add industries first.
The decision table
| Factor | TikTok Ads | LinkedIn Ads | Authority |
|---|---|---|---|
| Minimum daily | Campaign $50+; ad group $20+ | $10, any format | Vendor help pages |
| Minimum lifetime | Ad group $20 × days (31 days = $620) | $100 new; then $10 × days | Vendor help pages |
| Billing | CPC, CPM, CPV | CPC, CPM, CPS (Message Ads) | Vendor pages |
| Planning CPM | $8.00 | $36.23 | Planning assumption |
| Planning CPC | $0.80 | $9.39 | Planning assumption |
| Worked CPL | $26.67 | $93.90 | A1–A6 |
| Cost per meeting | $740.74 | $1,117.86 | A1–A6 |
| Targeting | Interests; broad | 20+ attributes; job title, company | Vendor pages |
| Audience floor | None published | 300 members, reported | Reported, not verified |
The reproducible math
Planning assumptions, used on both sides. TikTok: CPM $8.00, CPC $0.80, implied CTR 1.00% ($8.00 ÷ ($0.80 × 10)); click-to-lead 3%; lead-to-MQL 20%; MQL-to-SQL 30%; SQL-to-meeting 60%. LinkedIn: CPM $36.23, CPC $9.39, implied CTR 0.39% ($36.23 ÷ ($9.39 × 10)); click-to-lead 10% on Lead Gen Forms; lead-to-MQL 35%; MQL-to-SQL 40%; SQL-to-meeting 60%. Deal value $12,000 and close rates are planning assumptions for the revenue examples only.
— A1, TikTok at $1,000 a month: impressions 125,000; clicks 1,250; leads 37.5; CPL $26.67; MQLs 7.5; SQLs 2.25; meetings 1.35; cost per meeting $740.74.
— A2, LinkedIn at $1,000 a month: impressions 27,601; clicks 106.50; leads 10.65; CPL $93.90; MQLs 3.73; SQLs 1.49; meetings 0.89; cost per meeting $1,117.86.
— A3, TikTok at $5,000 a month: impressions 625,000; clicks 6,250; leads 187.5; CPL $26.67; MQLs 37.5; SQLs 11.25; meetings 6.75; cost per meeting $740.74.
— A4, LinkedIn at $5,000 a month: impressions 138,007; clicks 532.48; leads 53.25; CPL $93.90; MQLs 18.64; SQLs 7.46; meetings 4.47; cost per meeting $1,117.86.
— A5, TikTok at $10,000 a month: impressions 1,250,000; clicks 12,500; leads 375; CPL $26.67; MQLs 75; SQLs 22.5; meetings 13.5; cost per meeting $740.74.
— A6, LinkedIn at $10,000 a month: impressions 276,014; clicks 1,064.96; leads 106.50; CPL $93.90; MQLs 37.27; SQLs 14.91; meetings 8.95; cost per meeting $1,117.86.
— A7, minimum-budget feasibility: a TikTok daily-budget campaign at the $50 floor costs $1,500 over 30 days, so a $1,000 envelope cannot run one for a full month. It fits as a lifetime budget — a 30-day ad group needs $20 times 30, or $600 — or as a 20-day flight at $50 a day. On LinkedIn the same $1,000 is $33.33 a day, above the $10 floor and the $25 suggested default.
— A8, the reach and meeting multiples: $36.23 divided by $8.00 is 4.53, so LinkedIn reach costs 4.53 times TikTok reach. $1,117.86 divided by $740.74 is 1.51, so a LinkedIn meeting costs 1.51 times a TikTok meeting.
— A9, revenue and the break-even close rate: assume a $12,000 deal value and a 20% close rate. At $5,000 a month, TikTok returns 6.75 meetings times 20% times $12,000, which is $16,200, a 3.24 return on ad spend. LinkedIn returns 4.47 meetings times 20% times $12,000, which is $10,734.83, a 2.15 return. For LinkedIn to match $16,200 from 4.47 meetings, each meeting must be worth $3,621.85 — a 30.18% close rate at a $12,000 deal value.
Targeting, formats and the funnel that follows the click
The click is where the platforms stop being comparable and start being complementary. On TikTok the click lands on your page, and the conversion depends on the page. On LinkedIn the click can stay inside the platform: Lead Gen Forms pre-fill profile data, which is why the planning click-to-lead rate here is 10% against TikTok's 3%. That pre-fill is also why LinkedIn leads convert to MQL at 35% in the planning assumptions against TikTok's 20% — the form friction is lower, but the intent signal is weaker, because a member who taps a pre-filled form has not visited your site.
Retargeting differs on each side. On TikTok, pools are built from video viewers, engagers and site visitors, and Spark Ads boost the organic post that already earned engagement, keeping its likes and comments as social proof. On LinkedIn, Matched Audiences retarget website visitors through the Insight Tag and upload company or contact lists, with Predictive Audiences expanding a seed list. The CRM must tag the source on every lead.
Operator boundaries matter more than any rate. TikTok is for you when your buyer can be reached by interest; when you can produce short vertical video every two to four weeks; and when your offer converts on a landing page without a sales conversation first. LinkedIn is for you when the buyer is a defined job at defined companies and the deal size justifies a $93.90 cost per lead. TikTok is not for you when the buying committee is twenty named accounts in one region. LinkedIn is not for you when the budget is $1,000 a month and the goal is volume, because $1,000 buys 0.89 meetings at the planning rates.
The buying protocol
- Name the outcome first — meetings booked, not clicks or leads — and write the deal value and close rate down before spending.
- Check the floors: TikTok needs $1,500 a month for a daily-budget campaign or $600 for a 30-day lifetime ad group; LinkedIn needs $300 a month at the $10 floor.
- Build the LinkedIn audience first: company list plus job titles, location applied, forecast checked against the 300-member floor.
- Launch TikTok with three In-Feed Ads at 21 to 34 seconds, one hook each, broad targeting, Lowest Cost bidding, $30 a day.
- Launch LinkedIn with one Sponsored Content ad and a Lead Gen Form, Maximum Delivery bidding, $50 a day, CRM tagging the source on every lead.
- Run both for 7 to 14 days, then re-price: replace every planning rate with your actual CPM, CPC and CPL, re-run A1 to A9, and move next month's budget to the lower cost per qualified meeting.
Who should not buy which
A team with $1,000 a month and a named-account list under 300 members should not buy LinkedIn first — the audience will not serve. A team with no video production capacity should not buy TikTok — the two-to-four-week refresh cadence is a staffing commitment, not a suggestion. A team selling a $500 product should not buy LinkedIn Sponsored Content — a $93.90 cost per lead needs a $12,000 deal to survive the funnel. A team selling a $50,000 platform should not judge TikTok by its $26.67 cost per lead alone — the question is whether its meetings close, and the break-even in A9 is 30.18% on the LinkedIn side. A team that cannot tag leads by source in its CRM should buy neither until it can.
