Your TikTok Ads dashboard says you spent $60 per automotive lead last month. It doesn't say how many of those leads were a real person considering a car, versus a bot account filling out a pre-populated Instant Form. Lunio built its invalid traffic data layer to answer that second question, because platform reporting never will. Find out how much of your TikTok Ads budget is being wasted →
TikTok's automotive auction looks nothing like Google Search or Meta. Users aren't typing "2026 RAV4 lease deals" into a search bar, they're watching videos and getting exposed to vehicles they weren't actively shopping for yet. That discovery-first dynamic pushes automotive CPC and CTR below what performance marketers are used to seeing on intent-driven channels, while pushing CPL into a wide range depending on which conversion event an advertiser is actually optimising toward.
Every figure below is sourced externally and labelled accordingly. Where sources disagree significantly, both figures are shown with the methodology gap explained.
| Campaign Type | IVT Rate | CPC | CPM |
|---|---|---|---|
| In-Feed Ads | 24.20% (platform-wide) | $1.28 | $10.95 |
| Spark Ads | 24.20% (platform-wide) | $1.77 | $14.15 |
| TopView | 24.20% (platform-wide) | — | $16.10 |
| Search Ads Campaign | 24.20% (platform-wide) | — | $8.45 (cross-vertical) |
CPC and CPM figures above are automotive-specific (Auto & Auto Parts) from Digital Applied's Q1 2026 benchmark data, except the Search Ads Campaign CPM, which is a cross-vertical figure since TikTok Search Ads launched broadly in late 2025 and no automotive-specific data exists yet. The IVT rate column uses TikTok's platform-wide figure.
TikTok is effectively a mobile-only platform for automotive advertisers: 99% of impressions run on mobile devices, per Digital Applied's Q1 2026 data, leaving no meaningful desktop comparison to report.
Because there's effectively no desktop inventory on TikTok, the mobile figures above are the only figures that matter for automotive budget planning. US in-feed CPC for Auto & Auto Parts rose 7% year over year through Q1 2026, per Digital Applied, while the realistic planning range for US-focused dealers and OEMs remains $1.20 to $1.40 per click and $10 to $11 CPM for standard in-feed placements.
| Metric | Average | Notes |
|---|---|---|
| CTR | 0.94% (in-feed) | A CTR well above this range on an automotive campaign is worth investigating rather than celebrating. It can mean invalid clicks are inflating engagement without any matching rise in valid leads. |
| CVR | 1.42% lead submission / up to 9.02% upper-funnel | The gap reflects conversion event, not quality. If your account reports something closer to 9%, you're likely measuring content views rather than leads, which also means higher exposure to the view and engagement inflation invalid traffic produces. |
| CPA / CPL | $50 to $60 median, $40 to $90 range | This is the number dealer BDCs plan budgets against. If a meaningful share of these leads is invalid, the real cost per contactable, in-market lead runs higher than the dashboard shows. |
ROAS is deliberately excluded. Automotive on TikTok is almost entirely a lead-generation channel, vehicles aren't sold through TikTok Shop, and the metric that actually governs performance is cost per lead paired with downstream lead-to-sale conversion at the dealership. A cross-vertical TikTok ROAS figure applied to automotive planning will mislead more than it informs.
Every figure above comes from external sources: Digital Applied's Q1 2026 benchmark report, Two Minute Reports' 2025 automotive data, and Stackmatix's 2026 US estimates, cross-referenced against Lunio's verified platform-level invalid traffic rate. Neither TikTok Ads nor Automotive is currently covered in Lunio's proprietary 2026 benchmark dataset, which means the CPC, CPM, CTR, and CPL figures on this page are industry benchmarks rather than Lunio-measured figures, and the IVT rate is a platform-wide figure rather than an automotive-specific one. This page will be updated with verified Lunio figures as soon as that coverage launches.

Automotive advertisers on TikTok choose between several distinct campaign architectures, and each carries a different relationship to invalid traffic exposure. Understanding which format you're running matters more than chasing a single blended benchmark, especially once lead quality enters the conversation. See Lunio's guide to TikTok Ads strategy for a deeper breakdown of how each format behaves in auction.
In-Feed Ads: the baseline automotive format, exposed to TikTok's platform-wide 24.20% invalid traffic rate. Because in-feed is typically the first format a dealer or OEM scales, it's also usually the first place rising CPLs get noticed, and the first place worth auditing when they do.
Spark Ads: boosted creator content, carrying the same platform-wide 24.20% exposure but a materially different cost structure. At automotive's claimed 44% CVR lift over in-feed, the resulting CPA comes out to roughly $86.76 versus $90.14 for in-feed, a marginal improvement that may not justify the added cost and complexity of creator partnerships once invalid traffic is factored into both numbers equally.
TopView: the full-screen takeover format used for model launches, running at the same platform-wide exposure but at a much higher $16.10 CPM. Awareness-stage video metrics on TopView, like view-through rate, are among the easiest automotive metrics to inflate with non-human traffic because there's no conversion event downstream to catch the discrepancy.
Lead Generation with Instant Forms: the format carrying the highest structural IVT risk for automotive. TikTok's Instant Forms pre-populate user data from TikTok profiles, which reduces friction for genuine prospects but also removes the friction that would normally filter out a bot account submitting a form with real-looking data. Every invalid submission here lands directly in a dealer's CRM at the full cost per lead.
Smart+ Automotive Ads: TikTok's recommended automated campaign type, which controls targeting, bidding, and placement with limited advertiser visibility. If invalid form submissions register as positive conversion signals, the algorithm learns to find more users who resemble those submissions rather than more genuine car buyers, a contamination loop that shows up as gradually rising CPLs rather than a clean line item in reporting.
Automotive Ads for Inventory and Models: TikTok's catalog-based automotive products, built for dealership-level inventory promotion and OEM-level model campaigns respectively. Toyota reported a 38% CPA reduction using the Automotive Ads format versus standard lead gen, per TikTok for Business's published case study, though no absolute CPL figure was disclosed.
Search Ads Campaign: TikTok's intent-capture format, launched broadly in late 2025. No automotive-specific benchmark data exists yet for this format, though its closer position to purchase intent should carry different invalid traffic dynamics than discovery-stage in-feed placements.
| Country | IVT Rate | CPC | CPM |
|---|---|---|---|
| United States | 8.44% | $1.18 | $10.72 |
| United Kingdom | 7.97% | $1.04 | $9.85 |
| Germany | 6.34% | — | — |
| France | 6.63% | — | — |
| Australia | 7.87% | — | — |

CPC and CPM figures above are cross-vertical TikTok Q1 2026 averages (Digital Applied), not automotive-specific, since no automotive country-level cost data exists outside the US. IVT rates are Lunio's verified country-level figures across all verticals, per the 2026 Global Invalid Traffic Report. The US combines the highest cost per click in this table with the highest country-level invalid traffic rate, making it the clearest double-risk market for automotive advertisers scaling TikTok spend. Canada and Germany sit at the other end, with IVT rates roughly a quarter lower than the US. For a full country-by-country breakdown, see Lunio's ad fraud data by country.
TikTok's overall invalid traffic rate of 24.20% is the highest Lunio records across any major ad platform, per the 2026 Global Invalid Traffic Report. Automotive's conversion model makes that exposure worse before it makes it better: Lunio's broader dataset shows lead-generation campaigns carry 32.07% higher invalid traffic rates than transactional campaigns, and automotive on TikTok is almost entirely lead-gen. There is no meaningful transactional activity to offset it, since vehicles aren't purchased through TikTok Shop.
Run the maths on a realistic $500,000 annual TikTok automotive budget. Applying the platform-wide 24.20% rate produces $121,000 in spend going toward clicks, views, and form fills that never reached a genuine in-market buyer. That figure doesn't include the dealer BDC hours spent chasing invalid leads that will never answer a call, which sit on top of the media waste as a separate operating cost. A national OEM running $1 million annually would be looking at roughly $242,000 on the same basis.
Treat the figure above as a conservative illustration built on real platform data rather than a guaranteed account-specific number. The only way to know your actual share is to measure it directly.

Every CPC, CTR, and CPL figure on this page describes what TikTok's dashboard reports, not what you actually paid per real buyer. The gap between those two numbers is invalid traffic, and on a platform running a 24.20% IVT rate with automotive's lead-gen model stacked on top, that gap can be significant. Benchmarks tell you what's typical for the industry. Only a direct audit tells you what's happening in your own account.

Automotive in-feed CPC on TikTok runs around $1.28, per Digital Applied's Q1 2026 Auto & Auto Parts data, with US-focused advertisers typically planning for $1.20 to $1.40. Broader global medians run as low as $0.58, per Two Minute Reports' 2025 automotive data, because that figure blends lower-cost markets and awareness-focused campaign objectives into a single average.
A typical in-feed CTR for automotive sits around 0.94%, below TikTok's broader cross-vertical average, which is expected given the long consideration cycle of a vehicle purchase. A CTR that sits well above this range without a matching rise in valid, contactable leads is worth investigating, since invalid traffic can inflate click and engagement metrics without producing any genuine buyer interest behind them.
Every CPC, CPM, CTR, and CPL figure reported by TikTok includes whatever share of invalid traffic is present in your account, meaning your real cost per valid interaction is higher than the dashboard number. On a platform with a 24.20% overall invalid traffic rate, and with automotive's lead-gen model carrying a documented 32.07% higher invalid traffic rate than transactional campaigns, the gap between reported and real performance can be substantial, particularly in Smart+ Automotive Ads campaigns where contaminated conversion signals can actively worsen targeting over time.
Among the markets Lunio tracks, the United States carries an 8.44% invalid traffic rate, the highest of the group, while Germany sits at 6.34% and France at 6.63%. The UK falls in between at 7.97%. Because the US also runs the highest automotive CPC in the comparison, it represents the clearest combination of high cost and high invalid traffic exposure for automotive advertisers on TikTok.
