Benchmark dashboards for Microsoft/Bing Ads report a steady cost-per-demo for B2B SaaS accounts, but they rarely disclose how many of those "conversions" were ever submitted by a real buyer. Lunio builds the invalid traffic (IVT) data layer missing from every published benchmark, showing what share of that reported performance is actually reaching humans who can buy your product.

Microsoft/Bing Ads Benchmarks for B2B SaaS at a Glance
- Average CPC: No single, sample-size-disclosed figure exists for B2B SaaS specifically on Microsoft/Bing Ads in 2026. Cross-referencing WordStream's 2017 Technology category baseline of $1.95 (Q3 2017, 1,242 US accounts), Improvado's 2026 cross-industry Microsoft Ads range of $1.50–$2.80, and CloudSwitched's 2026 UK SaaS/Technology figure of £1.40 points toward a working range of roughly $1.50–$2.50 for non-brand search.
- CPM & CTR: No verified 2026 CPM figure exists for B2B SaaS on the Microsoft Audience Network, so it's omitted rather than estimated. Search CTR for B2B Services sat at 3.01% per WordStream's 2017 data, with CloudSwitched's 2026 UK cross-industry search CTR at 3.2% as a contemporary cross-check, while Audience Network placements run far lower at 0.4–0.65% for B2B segments per Aimers, January 2026, and double-digit brand search CTR (10–18%, Aimers 2026) tells you nothing about non-brand pipeline health.
- Invalid traffic rate: Microsoft/Bing Ads' overall invalid traffic rate sits at 10.32% across all verticals, while B2B SaaS and other software advertisers average 6.48% IVT across platforms as part of the Software & IT category, per the Lunio 2026 Global Invalid Traffic Report, covering 2.7 billion clicks across 6 ad platforms from August 2024 to July 2025.
- Your hidden cost: Even toward the lower end of that range, a B2B SaaS account spending $200,000 a year on Microsoft/Bing Ads could be losing tens of thousands of dollars to invalid clicks and fake form fills before Smart Bidding ever gets contaminated.

Microsoft/Bing Ads Benchmarks for B2B SaaS: Overall Metrics
Microsoft/Bing Ads auctions for B2B SaaS keywords look structurally different from Google's. Lower advertiser density keeps CPCs 30–50% below Google Ads in many B2B niches (per Aimers, January 2026), but the Bing Search Network's desktop-heavy, workplace-device audience also means fewer, higher-intent clicks rather than high volume. That combination is exactly why a traffic-quality layer matters here: a smaller click pool means each invalid click or fake form fill carries disproportionate weight on both cost and Smart Bidding signals.
| Campaign Type | IVT Rate |
|---|---|
| Brand Search | 10.32% (platform baseline) |
| Non-Brand & Competitor Search | 10.32% (platform baseline) |
| Microsoft Audience Network (MSAN) | 10.32% (platform baseline) |
These rows all carry the same figure because no campaign-type-specific IVT data exists yet for Microsoft Ads in B2B SaaS, so each uses the verified Microsoft/Bing Ads platform average of 10.32%. The universal pattern across other platforms, Google Display runs 12.02% IVT against 5.21% for Google Search, and Google Video Partners reach 20.62%, suggests MSAN likely sits above search once vertical-specific data arrives, even though no exact Microsoft figure exists today. Bing's desktop skew does provide some offsetting resilience: Microsoft's own data shows desktop conversion rates run 52% higher than mobile (Microsoft Advertising blog, September 2025, cited by Lever Digital, February 2026), consistent with a workplace-device, high-intent audience rather than mobile click-farm traffic.
Average CPC & CPM: Mobile vs. Desktop
No source in the current research disclosed a verified mobile-versus-desktop CPC split for B2B SaaS on Microsoft Ads, so no device-level CPC figure is presented here. What is verified is the device-level conversion gap: desktop converts 52% higher than mobile (Microsoft Advertising, September 2025), which matters more to a B2B SaaS buyer than CPC alone, since Bing's Windows-and-Edge default position concentrates traffic on corporate desktops during business hours. That skew is also a partial IVT mitigant, mobile device emulation and click-farm traffic, a known contributor to invalid clicks on other platforms, has less surface area on a desktop-heavy network.
Additional Metrics: CTR, CVR, CPA/CPL & ROAS
| Metric | Average | Notes |
|---|---|---|
| Search CTR (non-brand, B2B) | ~2.4%–3.2% | WordStream's 2017 B2B Services (3.01%) and Technology (2.40%) figures, cross-checked against CloudSwitched's 2026 UK cross-industry search CTR of 3.2%. A non-brand CTR well above this band, especially on MSAN, is more often a sign of bot-driven impressions than genuine buyer interest. |
| Search ROAS (cross-industry) | 4.2x | Per CloudSwitched, March 2026, UK cross-industry Search ROAS. B2B SaaS's 30–180 day sales cycle and multi-touch attribution make in-platform ROAS unreliable on its own, and any invalid conversions baked into reported pipeline inflate the figure further. |
Conversion rate and cost-per-lead data exist for B2B SaaS, but they come from third-party benchmark panels rather than Lunio's proprietary dataset, so they're surfaced here in prose instead of the table above. Benchmarketing's SaaS cohort (Q1 2023–Q4 2024) puts Microsoft Ads CVR at a 4.2% median, a 7.5% top quartile, and a 1.9% bottom quartile. Lever Digital's framework (February 2026) treats a 2–3% demo-request CVR on non-brand search as healthy, with softer actions like content downloads running higher. On cost, Aimers (January 2026) puts typical B2B SaaS search CPL at $80–$180, well above the $38.50 cross-industry Microsoft Ads CPA cited by Improvado (August 2026) and roughly consistent with WordStream's 2017 Technology CPA of $102.94 once adjusted for inflation.
A Note on This Data
For this combination, every IVT figure above uses the verified platform rate (10.32%) and the Software & IT industry average (6.48%) from the Lunio 2026 Global Invalid Traffic Report rather than a combination-specific rate. For directional context, Lunio's analysis of 414 million retail ad clicks found Bing (Microsoft Ads) averaging 4.46% IVT between Q4 2025 and Q2 2026, the only platform in that cohort to improve over the period, though that figure is retail-vertical, not B2B SaaS, and is cited here as a structural reference point rather than a verified B2B SaaS benchmark.

Microsoft/Bing Ads Benchmarks for B2B SaaS by Campaign Type & Placement
B2B SaaS teams on Microsoft Ads typically run several distinct campaign types side by side, each with its own volume, intent, and exposure profile. The IVT figure below reflects the verified platform baseline of 10.32% for every type rather than an invented per-type number, and CPC is left out of this section entirely.
Brand Search runs at the platform baseline of 10.32% IVT. Volume is low, so even a handful of invalid clicks on a thin daily budget skews reported performance more than it would on a higher-volume campaign.
Non-Brand Search, the primary demand-capture engine for demo requests and trial signups, also sits at the 10.32% baseline. This is the campaign type most exposed to the structural lead-gen risk discussed below, since every conversion action here is a form submission rather than a verified purchase.
Competitor Search carries the same baseline IVT exposure, but B2B SaaS deal values of $10,000–$100,000+ ACV give rivals a direct financial incentive to click and exhaust a competitor's daily budget, and Microsoft's thinner auction can make a single advertiser a more visible target than on Google.
Dynamic Search Ads (DSA) automatically trigger on long-tail queries, which widens the net of impressions and clicks an account absorbs and reduces an advertiser's control over exactly which queries feed reported CTR and conversion data.
Microsoft Audience Network (MSAN) is native display inventory across MSN, Outlook.com, and Edge. Display and native placements universally carry higher IVT than search across every platform with verified data, Google Display's 12.02% against Google Search's 5.21% is the clearest proof point, so B2B SaaS accounts blending MSAN with search should expect a combined rate above search-only exposure, even without a Microsoft-specific MSAN figure to cite yet.
Remarketing via RLSA and Customer Match targets warm, previously-engaged audiences and tends to show the strongest legitimate conversion rates in the Benchmarketing SaaS panel, but remarketing lists built from bot-visited pages can quietly reintroduce the same contamination they're meant to avoid.
Microsoft/Bing Ads Benchmarks for B2B SaaS by Country & Region
| 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 both the largest concentration of B2B SaaS Microsoft Ads spend and the highest verified country-level IVT rate in this cohort at 8.44%, making it the single largest dollar-exposure market for most accounts. The UK follows closely at 7.97%, while Germany (6.34%) and Canada (6.29%) show comparatively lower invalid traffic exposure, which matters when deciding where to concentrate incremental Microsoft Ads budget in a multi-market B2B SaaS program. See Lunio's ad fraud data by country for the full regional breakdown.
How Much of Your Microsoft/Bing Ads Budget Is Being Wasted on Invalid Traffic?
Working from a cross-platform search IVT range adjusted for Microsoft's smaller, more desktop-oriented network, a reasonable illustrative estimate for B2B SaaS search on Microsoft Ads sits around 8–12%; not a Lunio proprietary figure for this combination, but a structurally-reasoned range. On a mid-market account spending $200,000 a year on Microsoft/Bing Ads, a 10% IVT rate means roughly $20,000 a year disappears into invalid clicks and form fills before it ever touches a real prospect. At the $80–$180 CPL range Aimers reports for B2B SaaS search (January 2026), that waste represents somewhere between 110 and 250 fake leads landing in the CRM annually, each one consuming SDR time that never converts.
The exposure is structurally higher than a blended average suggests. Lunio's cross-platform analysis found that lead-gen campaigns run roughly 32.07% higher IVT than transactional campaigns, per the Lunio 2026 Global Invalid Traffic Report, and B2B SaaS converts almost exclusively through demo requests, free trial signups, and content downloads rather than real-time purchases with payment verification. That makes B2B SaaS lead-gen funnels on any platform, including Microsoft Ads, a structurally higher-risk category than the blended average implies.
Lunio's work with B2B SaaS company Canto shows what closing this gap looks like in practice: 79.17% of invalid traffic eliminated, $67,400 saved per month, and $350,000 in new pipeline generated within two months of deploying Lunio's protection. That's the difference between a benchmark number and the budget it actually protects.

Microsoft/Bing Ads Benchmarks for B2B SaaS: Why the IVT Layer Changes the Math
Every CPC, CTR, and CVR figure on this page describes reported performance, not verified human performance, and for B2B SaaS lead-gen funnels on Microsoft Ads that gap is structural, not incidental. A benchmark table tells you what the industry pays and converts at on average; it can't tell you what share of your own account's clicks and demo requests came from real buyers. Lunio's traffic audit closes that specific gap.

FAQ
What is the average CPC for B2B SaaS on Microsoft/Bing Ads?
No single, sample-size-disclosed 2026 figure exists specifically for B2B SaaS on Microsoft Ads. Synthesizing WordStream's 2017 Technology baseline ($1.95), Improvado's 2026 cross-industry range ($1.50–$2.80), and CloudSwitched's 2026 UK SaaS figure (£1.40) points to a working non-brand search range of roughly $1.50–$2.50, typically 30–50% below equivalent Google Ads CPCs in the same B2B niches.
What's a good CTR for Microsoft/Bing Ads in B2B SaaS, and when is a high CTR a warning sign?
Non-brand search CTR in the 2.4%–3.2% range is consistent with WordStream's and CloudSwitched's benchmarks, while Microsoft Audience Network CTR for B2B segments typically runs 0.4%–0.65% per Aimers. A CTR significantly above these ranges on non-brand or MSAN campaigns, especially without a matching rise in qualified demo requests, is a signal worth investigating rather than celebrating.
How does invalid traffic affect my Microsoft/Bing Ads benchmarks?
Invalid traffic inflates reported CTR and CVR while understating real CPA, because the clicks and form fills behind those numbers include non-human activity. It also contaminates Smart Bidding: with many B2B SaaS campaigns generating fewer than 30 conversions a month, a single fake demo request can represent a meaningful share of the algorithm's monthly learning signal, pushing bids toward the traffic that produced it rather than toward real buyers.
How do Microsoft/Bing Ads IVT rates differ between the US and Europe?
Verified country-level IVT rates put the US at 8.44% and the UK at 7.97%, both above Germany (6.34%), France (6.63%), and Canada (6.29%). For B2B SaaS advertisers running Microsoft Ads across multiple markets, the US combines the largest typical spend allocation with the highest IVT exposure in this cohort, making it the market where traffic quality monitoring delivers the largest dollar impact.
