Google Ads dashboards for Gambling advertisers report a clean cost per click and a defined cost per acquisition, but neither number reveals how many of those clicks came from a real, addressable bettor rather than a bot completing a sign-up form. Lunio's invalid traffic data layer measures that gap directly, and this page combines it with the only published Google Ads benchmarks specific to the Gambling vertical.

Google Ads Benchmarks for Gambling at a Glance
Average CPC: Google Ads Search campaigns for Gambling advertisers average $0.283 per click, per Lunio's 2026 Google Ads Gambling benchmark dataset. That sits well below the $2.69 cross-vertical Search CPC average reported by BrightBid's 2026 Google Ads Benchmarks report, reflecting how per-jurisdiction certification limits the number of advertisers who can even bid in a Gambling auction.
CPM & CTR: No Gambling-specific CPM or CTR figure is published anywhere, so the closest reference points are cross-vertical: a median CPM of $15.35 and a Search CTR range of 3.17% to 6.11%, per Triple Whale's and BrightBid's respective 2026 Google Ads benchmark reports. High-intent betting queries likely push Gambling CTR toward the upper end of that range, but a high CTR on Display or Demand Gen inventory can signal bot clicks just as easily as genuine interest.
Invalid traffic rate: Lunio's 2026 Google Ads Gambling benchmark dataset shows IVT rates ranging from 2.06% on Shopping to 14.57% on Display, with Search sitting near the cleaner end at 2.92%. Which campaign type a Gambling advertiser scales into determines how much of the budget even reaches a real bettor.
Your hidden cost: On a Display campaign alone, a 14.57% IVT rate means roughly one in seven clicks never had a chance to convert, let alone deposit. Lunio runs a free 14-day traffic audit that measures this rate on your own Google Ads account rather than an industry average. Calculate how much you're losing →
Google Ads Benchmarks for Gambling: Overall Metrics
Gambling occupies an unusual position on Google Ads: certification requirements cap the number of advertisers who can even enter the auction, keyword intent is about as high as digital advertising gets, and several ad formats, including Gmail ads, Shopping-style listings for real-money products, and YouTube Masthead, are closed off entirely under Google's Gambling and Games policy. That combination produces a cost and conversion profile that looks nothing like a typical Google Ads account, which is exactly why cross-vertical benchmark tables mislead Gambling advertisers rather than help them.

Sports betting and casino search queries skew heavily toward mobile, since bettors place wagers in the moments before or during live events. Directionally, Display and Demand Gen inventory that serves largely through mobile apps and mobile web carries the same placement-quality risk that pushes IVT higher on those campaign types above.
Additional Metrics: CTR, CVR, CPA/CPL & ROAS
Metric |
Average |
Notes |
|---|---|---|
CTR |
3.17% to 6.11% (Search, cross-vertical, BrightBid 2026) |
No Gambling-specific figure exists. High-intent betting queries likely sit near the top of this range, but a strong CTR on Display or Demand Gen can reflect bot clicks as easily as bettor interest. |
CVR |
1.38% to 19.93% across campaign types (Lunio 2026 Gambling dataset) |
Search's 19.93% almost certainly reflects account registration rather than first-time deposit. Bots can complete a low-friction sign-up form just as easily as a real bettor, which is exactly the funnel stage where IVT matters most. |
CPA/CPL |
$0.98 to $114.90 depending on campaign type (Lunio 2026 Gambling dataset) |
Every figure includes some share of conversions from the IVT rate reported in the same campaign type, meaning the true cost per legitimate registration runs higher than the headline number. |
ROAS |
3.27x median, cross-vertical (Triple Whale 2026) |
Gambling ROAS cannot be read from an ecommerce-style benchmark: revenue is measured in NGR or GGR rather than order value, and a depositing player's value accrues over months, not a single transaction. |
A Note on This Data
The campaign-type figures above come from Lunio's detection engine running in monitor-only mode on live Google Ads Gambling accounts in 2026, meaning traffic was observed and classified without being blocked. Account counts per campaign type range from just one, for Display and Shopping, to four, for Search, so these are directional indicators from real Gambling accounts rather than statistically robust vertical averages. CTR and ROAS figures are cross-vertical proxies from BrightBid's and Triple Whale's 2026 Google Ads benchmark reports because no Gambling-specific published source exists for either metric.

Google Ads Benchmarks for Gambling by Campaign Type & Placement
Every campaign type on Google Ads draws on a different mix of inventory, and for Gambling advertisers that mix determines how much of the reported CPA reflects a real, addressable bettor. The pattern in Lunio's dataset is consistent: the further a campaign type moves from pure Search inventory, the higher its IVT rate climbs.
Search is the cleanest channel in the Gambling mix at 2.92% IVT and a $0.283 CPC, per Lunio's 2026 Google Ads Gambling benchmark dataset. Even so, 2.92% is traffic that had already passed through Google's native click quality filters before reaching the advertiser, meaning it still contaminates the registration data feeding Smart Bidding. Layering AI Max onto Search campaigns adds further exposure: AI Max increases IVT exposure by roughly 35% above the Search baseline, per Lunio's 2026 Global Invalid Traffic Report, which is a meaningful addition for a Gambling advertiser already running lean Search margins. See Lunio's breakdown of AI Max's hidden risks for the mechanism.
Display carries the highest IVT rate in the dataset at 14.57%, against a CPC of just $0.013, in the single Gambling Display account Lunio measured. The per-click cost is negligible, but at that rate roughly one in seven Display clicks is invalid, which is a volume risk rather than a per-click one, and one that compounds quickly on any account scaling Display spend for brand awareness or retargeting.
Performance Max sits between Search and Display at 4.53% IVT and a $0.245 CPC, which is exactly what you would expect from a campaign type that blends Search, Display, YouTube, Discover and Gmail inventory without reporting which surface served which click. The CPA of $1.48 looks nearly identical to Search's $1.45, but PMax's blended IVT rate means a larger share of the conversions behind that number are unverifiable, and Smart Bidding has no way to separate a genuine registration from a bot-completed one when it decides where to bid next.
Video is the most expensive click in the Gambling mix at $1.962 CPC, with a comparatively contained 3.23% IVT rate across the two accounts Lunio measured. That account-level figure is worth treating with some caution: Google Video Partners inventory overall runs at a 20.62% IVT rate, per Lunio's invalid traffic rates by ad platform, so a Gambling advertiser shifting more Video budget toward partner network placements rather than YouTube itself should expect exposure well above 3.23%.
Demand Gen combines a high IVT rate of 9.57% with the second-highest CPA in the dataset at $58.15. At that IVT rate, roughly one in ten Demand Gen conversions is invalid, meaning close to $58 is spent to acquire nothing on a meaningful share of reported registrations, the most expensive false conversion of any campaign type in the Gambling mix.
Shopping is the cleanest and cheapest campaign type at 2.06% IVT and a $0.093 CPC, though this is likely serving merchandise, affiliate products or social casino apps rather than real-money gambling products directly, given Google's restrictions on Shopping-style ad formats for regulated gambling.

Germany and Australia are the double-risk markets in this dataset. Germany combines the second-highest CPC at $0.304 with a 9.49% IVT rate, while Australia's CPC is the lowest of the six at $0.028 but carries by far the highest IVT rate at 16.51%, more than one in six clicks. Both are worth a closer look for any Gambling advertiser running budget there, particularly given Australia's heavily contested sports-betting market. The UK looks like the opposite case: the highest CPC of the six at $0.293, but the lowest IVT rate at 2.11%, consistent with the UK Gambling Commission's mature, tightly regulated advertising environment.

How Much of Your Google Ads Budget Is Being Wasted on Invalid Traffic?
Across all ad platforms, not just Google Ads, Gambling ranks among the highest-IVT verticals measured: 18.49% per Lunio's 2026 Global Invalid Traffic Report, covering 2.7 billion clicks across 6 ad platforms from August 2024 to July 2025. On Google Ads specifically, applying Lunio's campaign-type IVT rates to a representative $2 million annual Gambling budget, split roughly 40% Search, 25% Performance Max, 10% Display, 10% Video, 10% Demand Gen and 5% Shopping, produces a direct waste figure of approximately $102,810 a year, about 5.1% of total spend, before accounting for the downstream cost of Smart Bidding optimizing toward invalid conversion signals or welcome bonuses allocated to accounts that never deposit.
Gambling's funnel makes this worse than it looks. Because the primary tracked conversion on Google Ads is registration rather than a purchase, Gambling sits structurally in the higher-IVT lead-gen category: lead-generation funnels carry a 32.07% higher IVT rate than transactional ones, per Lunio's 2026 Global Invalid Traffic Report, because a form requiring only an email address and a date of birth is far easier for a bot to complete than a checkout requiring payment. A single fake registration does not just inflate a reported conversion count. It can trigger a $10 to $50 welcome bonus allocation and pollute the CRM data a retention team later tries to work with.

Google Ads Benchmarks for Gambling: What the Numbers Don't Show
The benchmarks above are the only Gambling-specific numbers published for Google Ads, but they are still a starting point rather than an answer. A 4.53% IVT rate on Performance Max or a 9.57% rate on Demand Gen means a real share of the conversions behind those CPA figures never belonged to a bettor at all, and platform reporting has no way to show you which ones. Lunio measures that gap on your specific account, by campaign type and by country, rather than leaving you to apply an industry average to your own budget.

FAQ
What is the average CPC for Gambling on Google Ads?
Search campaigns average $0.283 per click for Gambling advertisers, per Lunio's 2026 Google Ads Gambling benchmark dataset. That is dramatically lower than the $2.69 cross-vertical Search CPC average reported by BrightBid's 2026 Google Ads Benchmarks report, mainly because per-jurisdiction certification limits how many advertisers can even bid in a Gambling auction. CPC varies sharply by campaign type too, from $0.013 on Display to $1.962 on Video.
What's a good CTR for Google Ads in Gambling, and when is a high CTR a warning sign?
No Gambling-specific CTR benchmark exists, but cross-vertical Search CTR runs 3.17% to 6.11%, per BrightBid's 2026 report, and high-intent betting queries likely sit near the top of that range. A high CTR on Display or Demand Gen inventory is a different signal, though: those are the campaign types where Lunio's Gambling dataset shows the highest IVT rates, 14.57% and 9.57% respectively, so an unusually strong CTR there can reflect bot clicks as easily as genuine bettor interest.
How does invalid traffic affect my Google Ads benchmarks?
IVT inflates the volume behind every metric that feeds Smart Bidding, particularly for Gambling's low-friction registration conversion event, which bots can complete without a payment step. A 4.53% IVT rate on Performance Max or a 9.57% rate on Demand Gen means a real share of the reported CPA and CVR figures in this article reflect conversions that never came from an actual bettor, which is why the campaign type you are scaling matters as much as the headline number.
How do Google Ads IVT rates differ between the US and Europe?
In Lunio's 2026 Gambling dataset, the US shows a 6.80% IVT rate, while Germany sits higher at 9.49% and the UK is markedly lower at 2.11%. France sits in between at 4.83%. There is no single European pattern here: the UK's tightly regulated, mature Gambling Commission market looks structurally cleaner than Germany's, so geography-level generalizations are less useful than checking your own market's rate directly.
