Your Google Ads dashboard says the Automotive campaign is performing on benchmark, but your BDC team is still fielding leads that never answer the phone. Lunio exists to close that exact gap, showing dealership and aftermarket advertisers what share of Google Ads spend reaches a real buyer rather than a bot, a competitor, or a fake form fill. Find out how much of your Google Ads budget is being wasted →
Automotive is one of the most fragmented auction environments on Google Ads. A single searcher comparing used trucks can trigger ads from a dozen local dealers, three national aggregators, and an OEM brand campaign, all competing for the same click. That density, combined with a buyer journey that spans weeks of research before a single in-store transaction, makes benchmark interpretation harder here than in most verticals covered on Google Ads, a pattern explored further in Lunio's look at invalid traffic inside Google Ads.
| Campaign Type | IVT Rate | CPC | CPM | CPA / CPL |
|---|---|---|---|---|
| Search (Dealership & Repair, blended) | 5.21% (Google Search platform rate) | $3.13 (LocaliQ) | Not reported | $32.79 (LocaliQ CPL) |
| Performance Max (Vehicle Inventory & Aftermarket) | 7.88% (Google PMax platform rate) | Not reported | Not reported | Not reported |
| Display (GDN) | 12.02% (Google Display platform rate) | Not reported | Not reported | Not reported |
| Shopping / PMax Ecommerce (Aftermarket) | 7.88% (Google PMax platform rate, proxy) | Not reported | $15.06 (Triple Whale) | $38.14 (Triple Whale CPA) |
Automotive searches run heavily mobile for service and repair (a broken car tends to be searched from a phone in a parking lot) and more desktop-weighted for new vehicle research, where buyers compare trims and financing across multiple sessions. No 2026 source in the current research set breaks Automotive CPC or CPM out by device, which is itself worth flagging to any practitioner building a media plan around it.
No Automotive-specific mobile versus desktop CPC or CPM split exists in any 2026 benchmark source currently available. The closest proxy is Terra HQ's cross-vertical observation that mobile conversion rates typically lag desktop by one to two percentage points across most industries, but this is a general pattern, not an Automotive measurement, and should be treated as directional context rather than a benchmark to plan against.
| Metric | Average | Notes |
|---|---|---|
| CTR | 6.17% (LocaliQ, Oct 2024–Sept 2025) | CTR rising while CVR falls, as seen in Triple Whale's ecommerce data below, is a classic signal that a growing share of clicks isn't coming from genuine buyers. |
| CVR | 8.80% (LocaliQ, Oct 2024–Sept 2025) | Blended across dealership and repair subcategories; the gap between a 3.93% dealership CVR and a 29.01% parts CVR shows how much a single average hides. |
| CPA / CPL | $32.79 (LocaliQ, Oct 2024–Sept 2025) | This figure assumes every recorded conversion is a genuine lead. If 10–13% of conversions are invalid, the real cost per genuine lead is materially higher. |
| ROAS | 4.07 (Triple Whale, Aug 2025–Jul 2026, ecommerce only) | This applies only to aftermarket ecommerce campaigns. No lead-gen ROAS benchmark exists for dealership sales or service campaigns in any 2026 source. |
Every figure above comes from LocaliQ's 2026 Automotive Search Advertising Benchmarks, Triple Whale's 2026 ecommerce benchmark set, or Google Ads' own verified platform-level IVT rates. Older figures still circulate in search results, including a WordStream dataset covering August 2017 to January 2018 (Auto CPC $2.46, CVR 6.03%, CPA $33.52) that is more than eight years out of date and should not be used as a current reference point. As Lunio's Automotive monitoring base grows, this page will be updated with account-measured IVT figures rather than platform-level proxies, consistent with the methodology in Lunio's 2026 Global Invalid Traffic Report.

Automotive advertisers rarely run a single campaign type. Dealerships combine Search for bottom-funnel intent, Performance Max for inventory and aftermarket reach, and Display or YouTube for awareness, each with a different invalid traffic profile. Understanding that profile matters more in Automotive than most verticals because a single fraudulent form fill or phone call can waste the entire marginal cost of a vehicle-sale lead.
Search. Standard Search carries Google's lowest platform-level IVT rate at 5.21%, making it the cleanest acquisition channel for dealership and repair campaigns. That advantage narrows for advertisers using AI Max for Search, which increases IVT exposure by roughly 35% above the Search baseline per Lunio's research, a risk covered in more depth in Lunio's analysis of AI Max for Search campaigns. For dealership groups adopting AI Max to automate audience and bid decisions, that increase deserves monitoring before scaling budget.
Performance Max. PMax carries a platform-level IVT rate of 7.88%, higher than standard Search because budget is allocated automatically across Search, Display, YouTube, Discover, and Gmail inventory with limited placement-level visibility. For Automotive advertisers using PMax for vehicle inventory or aftermarket products, this opacity means a meaningful share of spend could be landing on lower-quality placements without a clear way to see it inside the platform.
Display (GDN). Display carries a platform-level IVT rate of 12.02%, more than double the Search rate. Automotive advertisers using Display for retargeting or OEM awareness campaigns should treat this as a structurally higher-risk placement type, particularly where PMax is routing a portion of budget into Display inventory automatically.
YouTube and Video Partners. Google Video Partner inventory carries the highest platform-level IVT rate referenced here, at 20.62%. OEM brand campaigns and dealership awareness video running across partner inventory, rather than directly on YouTube, carry the clearest inventory quality gap of any Automotive placement type and warrant the most scrutiny.
Vehicle Listing Ads. VLAs are Google's automotive-specific inventory format, pulling from a vehicle feed to show price, image, and dealership name directly on the search results page. No 2026 source provides benchmark CPC, CTR, or IVT data for VLAs specifically. Given that VLAs draw on the same Shopping and Display infrastructure as other feed-based formats, the same caution that applies to PMax and Display placements likely extends here, even without a measured figure to cite.
| Country | IVT Rate |
|---|---|
| United States | 8.44% |
| United Kingdom | 7.97% |
| Germany | 6.34% |
| France | 6.63% |
| Australia | 7.87% |
| Canada | 6.29% |
The United States carries the highest IVT exposure of the six markets at 8.44%, which compounds against an already elevated Automotive CPC environment to create the clearest double-risk market for dealership groups: higher cost per click combined with higher invalid traffic exposure. The United Kingdom and Australia sit close behind at 7.97% and 7.87%. Canada and Germany offer relative efficiency at 6.29% and 6.34%, suggesting Automotive advertisers running cross-border campaigns may see meaningfully cleaner traffic in those markets even before accounting for currency or competitive differences. For a full country-by-country breakdown, see Lunio's ad fraud data by country.
Take a mid-sized dealership group spending $1,200,000 a year on Google Ads at the LocaliQ-reported blended CPC of $3.13. That budget buys approximately 383,400 clicks annually. At Google Ads' overall platform IVT rate of 7.57%, roughly 29,023 of those clicks are invalid, representing about $90,845 in direct wasted spend. Because dealership and service-appointment campaigns are lead-gen by definition, and lead-gen campaigns see 32.07% higher IVT rates than transactional campaigns per Lunio's ad fraud detection research, the lead-gen-adjusted estimate rises to roughly 10.0%, or about 38,340 invalid clicks and $120,000 in wasted annual spend.
That figure understates the real cost. At the LocaliQ-reported 8.80% CVR, 383,400 clicks produce roughly 33,739 recorded leads. If 10% of those are invalid, that's around 3,374 fake leads entering the CRM. At five minutes of BDC time per lead and a $20 per hour loaded labor cost, that's roughly $5,600 in wasted staff time on top of the ad spend waste, before accounting for the way fake leads corrupt Customer Match and remarketing audiences downstream.
This dynamic is not unique to vehicle sales. Driva, an automotive finance platform operating in a high-CPC environment of $20 or more per click, implemented Lunio before doubling its PPC spend and saw a 2.39% increase in search conversion rate alongside a 6.5% reduction in monthly wasted ad spend. The lead-gen mechanics are the same as a dealership test drive request or service appointment form: a high-value action, a form fill as the conversion event, and a Smart Bidding model that will optimise toward whatever traffic profile generates that signal, real or not.

Benchmarks are a starting point, not an endpoint. A CPL of $32.79 or a CVR of 8.80% only tells you what the industry pays and gets on average, not whether your own account's leads turn into test drives and vehicle sales. The gap between those two things is invalid traffic, and it's invisible until someone measures it directly. Lunio builds that measurement layer specifically for performance marketers, not as a security product but as a way to see which clicks and conversions represent real buyer intent before they reach your Smart Bidding model.

The blended average is $3.13 per click, per LocaliQ's Automotive Search Advertising Benchmarks covering October 2024 to September 2025. That average hides wide subcategory variance, from $1.77 for general used auto dealers to $6.89 for automotive glass repair and transmission repair. Older figures citing a $2.46 average come from a WordStream dataset dated August 2017 to January 2018 and should not be used as a current benchmark.
The blended Automotive CTR is 6.17%, ranging from around 4.55% for auto service and repair to over 10% for motorcycle dealers, per LocaliQ's 2026 data. A high CTR becomes a warning sign when it rises without a matching rise in conversion rate, as seen in Triple Whale's ecommerce Automotive data where CTR climbed 19.72% year-over-year while CVR fell 8.39% over the same period.
Published benchmarks are calculated on traffic that has passed Google's own general invalid traffic filtering, which catches known bots and spiders but does not prevent sophisticated invalid traffic, disguised bots, hijacked devices, or deliberate fake clicks, from completing a form fill or triggering a call extension. Those conversions still feed Smart Bidding's training data, which means your reported CPL and CVR may look healthier than the traffic quality behind them actually is.
The United States carries the highest IVT rate among major Automotive markets at 8.44%, compared with 7.97% in the UK, 6.63% in France, and 6.34% in Germany, all per Lunio's verified country-level data. Canada sits lowest at 6.29%, suggesting North American and European dealership groups running cross-border campaigns may see meaningfully different traffic quality depending on market.
