Your Microsoft/Bing Ads dashboard can show you clicks, registrations, and a CPA that looks reasonable for a sportsbook or online casino, but gambling is one of the most fraud-exposed verticals in digital advertising, and the dashboard alone can't tell you how much of that spend actually reached a real bettor. Lunio measures the gap between reported clicks and real human traffic across paid channels, adding the invalid traffic data layer that standard benchmark reports leave out entirely.

Microsoft/Bing Ads for gambling looks structurally different from Google Ads in the same vertical. The advertiser pool is small, often just three to six licensed operators bidding on the same core keyword set, which pushes impression share higher but also concentrates the financial impact of any single bad actor. Bing's audience skews desktop and higher-income relative to the open web, a demographic that aligns reasonably well with sports betting and online casino players but searches in smaller volume than on Google.
| Campaign Type | IVT Rate | CPC | CPM |
|---|---|---|---|
| Search | 10.32% (platform average) | $1.40–$4.20 (derived estimate) | – |
| Microsoft Audience Network (MSAN) | 10.32% (platform average) | $0.34 | $3.43 |
Bing's traffic skews toward desktop by a documented 42% margin relative to mobile, per Statcounter's Device Comparison 2026 (via Searchlab). For gambling, this matters: desktop sessions typically carry higher deposit values and longer play sessions than mobile, so an account showing heavier-than-expected mobile volume relative to this baseline is worth investigating for mismatched inventory or partner network contamination.
No published source breaks out gambling CPC or CPM by device specifically for Microsoft/Bing Ads. What is documented is the platform's overall desktop skew (42% higher desktop share than mobile, per Statcounter's Device Comparison 2026 via Searchlab) and the broader pattern that mobile click activity across digital advertising carries more invalid traffic risk than desktop. Gambling operators running Microsoft Ads should treat a mobile conversion rate that matches or beats desktop as a diagnostic flag rather than a win, since it runs against both the platform's typical device pattern and common invalid traffic patterns.
| Metric | Average | Notes |
|---|---|---|
| CTR | 4.1% (cross-vertical, Microsoft Advertising 2026 via Searchlab) | No gambling-specific CTR is published. Segment by Bing and Yahoo direct search versus syndicated search partners before trusting this figure, since partner inventory inflation is a documented risk across platforms. |
| ROAS | 2.8x (cross-vertical, Merkle Q4 2025 via Searchlab) | Gambling's lifetime value model ($200–$2,000+ per depositing player) makes short-window ROAS structurally unreliable in either direction unless adjusted for LTV and verified against real, not bot-inflated, conversion events. |
Every figure above comes from one of three sources: Lunio's verified platform-level IVT rate for Microsoft/Bing Ads, Lunio's cross-platform industry rate for Gaming & iGaming from the Lunio 2026 Global Invalid Traffic Report, or externally published cross-vertical Microsoft Ads benchmarks with the derivation shown wherever a gambling-specific range has been estimated. Rather than present outdated cross-vertical averages as if they were gambling-specific, every derived figure on this page states its inputs and assumptions openly. Calculate how much you're losing →
Gambling operators on Microsoft/Bing Ads have two realistic campaign formats available today: Search and the Microsoft Audience Network. Performance Max for Microsoft is newer and its policy status for gambling advertisers is unclear, so treat it as an emerging option rather than a confirmed channel until Microsoft's policy team has approved it for your account.
Search campaigns are the primary gambling format on Microsoft/Bing Ads, and the platform's overall account IVT rate of 10.32% is the most relevant available baseline since no gambling-specific figure exists yet. CPC for gambling search campaigns falls in an estimated $1.40 to $4.20 range, driven by high-value keywords like "online casino bonus" and "best sportsbook app." One mechanism specific to Microsoft Ads deserves separate attention: Bing's search results syndicate to Yahoo, AOL, and DuckDuckGo through the search partner network, and syndicated search inventory consistently carries higher invalid traffic than owned-and-operated search across every platform that publishes a breakdown. Gambling advertisers should segment reporting by "Bing and Yahoo Search" versus "Syndicated search partners" and treat an anomalously high CTR on partner traffic as a signal worth investigating rather than a performance win.
Microsoft Audience Network serves native ads for gambling retargeting on MSN, Outlook.com, and Edge, with an average CPC of $0.34 and CPM of $3.43, per Microsoft's 2026 MSAN Pricing Analysis and WordStream's Native Ads CPC data (via Searchlab). Programmatic and native placements for entertainment and gambling carry sophisticated invalid traffic rates of 7 to 12%, per DoubleVerify's Global Insights Report (2024), making MSAN a lower-cost but not necessarily lower-risk channel for depositing-player retargeting. This inventory quality gap between owned search and syndicated or native placements is the same pattern seen across every major platform, and it means a blended account-level IVT figure can hide a much higher rate sitting inside a single placement type.
| 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 among the markets Lunio tracks at 8.44%, per the Lunio 2026 Global Invalid Traffic Report, and it is also the market with the highest gambling CPCs given ongoing state-by-state legalisation and the concentration of major operators like DraftKings, FanDuel, and BetMGM bidding in the same auctions. The UK (7.97%) and Australia (7.87%) show similarly elevated exposure in markets where gambling advertising is well-established and CPCs sit above the global average. Germany (6.34%) and Canada (6.29%) offer comparatively lower IVT exposure, though gambling advertising remains tightly regulated in both. For gambling operators running Microsoft/Bing Ads across multiple licensed jurisdictions, the highest-spend markets and the highest-IVT markets largely overlap, compounding the financial exposure exactly where it matters most. See Lunio's ad fraud data by country for the full regional breakdown.
Take a mid-sized gambling operator spending $300,000 a year on Microsoft/Bing Ads search, with CPCs averaging around $2.50 across its keyword mix. That budget buys approximately 120,000 clicks a year. Applying the Gaming & iGaming industry average IVT rate of 18.49%, per the Lunio 2026 Global Invalid Traffic Report, covering 2.7 billion clicks across 6 ad platforms from August 2024 to July 2025, roughly 22,188 of those clicks are invalid, which works out to approximately $55,470 wasted in a single year.
The number gets worse for operators optimising toward registration rather than first deposit. Lunio's data shows lead-gen conversion models experience 32.07% higher IVT rates than transactional models, per the Lunio 2026 Global Invalid Traffic Report. Applied to the 18.49% Gaming & iGaming baseline, a registration-optimised sportsbook or casino campaign could see effective IVT exposure closer to 24.4%, pushing annual waste on the same $300,000 budget to roughly $73,260. That gap between the transactional baseline and the lead-gen-adjusted figure is not funnel friction. It is the direct cost of form-fill fraud and competitor click activity feeding your conversion data.
This pattern isn't unique to gambling. In a comparable high-CPC lead-gen paid search environment, one Lunio client reduced its average invalid traffic rate by 81.41%, from 16.84% to 3.13%, across Google and Microsoft Ads, and saved 5.8% of total spend across both platforms, with top-performing keywords costing £30 to £40 per click, a cost level comparable to premium gambling terms. The same contamination mechanism applies directly to sportsbooks and online casinos running registration-optimised Target CPA campaigns on Microsoft Ads: the algorithm can't distinguish a real sign-up from a bot-generated one, so it learns to bid toward whatever produced the conversion signal it was given.

These benchmarks give gambling operators a starting point for Microsoft/Bing Ads, but every figure here is a reported number, not a verified one. The real question isn't whether your CPC or CPA matches an industry average, it's what share of the clicks and conversions behind that number came from a real potential depositor rather than a bot, a competitor, or a fraudulent affiliate. A traffic audit answers that question directly, without changing a single campaign setting first.

No published benchmark publisher reports gambling-specific CPC for Microsoft/Bing Ads directly. Based on Microsoft Ads' $1.37 cross-vertical average (WordStream Industry Benchmarks 2026, via Searchlab) and the documented CPC discount Microsoft Ads carries versus Google Ads, a directional range of $1.40 to $4.20 is a reasonable working estimate for gambling search keywords, though treat it as derived rather than measured.
The platform-wide cross-vertical CTR benchmark is 4.1% (Microsoft Advertising 2026, via Searchlab), but no gambling-specific figure exists. A CTR that sits notably higher on syndicated search partner traffic (Yahoo, AOL, DuckDuckGo) than on Bing and Yahoo direct search is a stronger signal of bot-driven click inflation than it is of strong ad copy, and it should be investigated before being treated as a win.
Invalid traffic inflates your reported click volume and, in registration-optimised campaigns, inflates your apparent conversion rate while understating your true depositing-player CPA. Because gambling's lead-gen conversion model (registration) carries a 32.07% higher IVT rate than transactional models (first deposit), per Lunio's 2026 Global Invalid Traffic Report, any benchmark built on registration data alone is likely understating your real acquisition cost.
Among the markets Lunio tracks, the US carries the highest IVT rate at 8.44%, followed by the UK at 7.97%, with Germany (6.34%), France (6.63%), and Canada (6.29%) running lower. For gambling operators, the US and UK combine high CPCs with higher IVT exposure, which compounds financial risk in exactly the markets where budgets are largest.
