Microsoft Ads runs ~30-60% cheaper CPCs than Google for the same intent. The audience skews older (45+), higher household income, more desktop. For B2B and high-ticket B2C, it frequently outperforms Google on CPA. The reason most accounts don't run it: nobody bothers to set it up. The Google → Microsoft import tool takes 10 minutes and replicates your account.
Why this question keeps coming up
"Should I run on Microsoft Ads?" gets asked roughly twice a week by clients evaluating their channel mix. The instinct — Google has 90%+ search share, why bother — is wrong, but for non-obvious reasons. The 10% of search that happens on Bing isn't a random 10%. It's structurally older, wealthier, more desktop, more enterprise than Google's median. For some audiences, that's worse. For others — most B2B SaaS, high-ticket B2C, financial services, healthcare — it's significantly better.
The other thing operators miss: auction density. Microsoft has ~one-third Google's volume but roughly one-fifth the bidders on the same keywords. That asymmetry pushes CPCs down without lowering quality. You're paying less because fewer people are bidding, not because the clicks are worse.
The side-by-side benchmarks
Aggregated across the accounts we've audited or managed in the last 24 months. These are reliable median ranges, not best-case cherry-picks:
- CPC: Microsoft typically 30-60% lower than Google for the same intent keywords. Larger gap in competitive verticals (finance, legal, insurance). Smaller gap in commodity niches.
- CTR: Roughly equivalent on Search. Microsoft's Audience Network CTR is lower than Google Display, but the conversion rate makes up for it.
- Conversion rate: Surprisingly similar in median (within 10% of each other). Microsoft skews higher for B2B; Google skews higher for impulse B2C.
- CPA: Microsoft often 20-40% lower for B2B, lead-gen, and high-ticket commerce. Google wins on volume-driven, low-AOV consumer goods.
- Audience reach: Google ~10x. Important if you're trying to scale spend past $50K/month in a niche.
- Audience demo: Microsoft median household income is ~50% higher than Google's. Age skews 10-15 years older. Desktop share roughly 2x.
Where Microsoft genuinely wins
1. B2B SaaS and enterprise lead-gen
The single clearest win. Decision-makers at companies (CFOs, IT directors, ops VPs) are statistically more likely on Bing — partly because corporate IT often sets Bing as the default search in Edge, partly because the audience is older. B2B SaaS accounts we run typically see Microsoft CPL 35-55% below Google for the same target keywords.
2. Financial services, legal, healthcare
Categories where Google's auction is brutally expensive ($50+ CPC on competitive keywords) frequently have Microsoft CPCs in the $15-25 range. Same audience intent, fraction of the cost. For accounts hitting Google CPC ceilings, Microsoft is often the only sane scale-up channel.
3. Audience Network for upper-funnel
Microsoft Audience Network places ads on MSN, Outlook.com, Edge new-tab, LinkedIn-feed-style placements, and partner sites. The targeting fidelity is decent and the CPM is fraction of Meta. For mid-funnel awareness with retargeting, it's an underused channel.
4. LinkedIn audience targeting on Search
This is the killer feature most operators have never used. Inside Microsoft Ads Search campaigns, you can layer LinkedIn profile attributes (Company, Job Function, Industry, Job Title) as bid adjustments. Targeting "people searching for [B2B keyword] who are also Marketing Directors at companies 200+ employees" doesn't exist anywhere else in paid search. For B2B accounts, this alone justifies running Microsoft.
Where Google still wins
1. Volume and scale
If you need to spend $100K+/month profitably on search, Google is the only platform with enough auction inventory. Microsoft Search caps out faster — usually around $30-50K/month before impression share losses make further spend inefficient.
2. Mobile-first audiences
Gen Z, mobile gaming, dating apps, mobile-first consumer brands — audiences whose search behavior happens 90% on phones — are underrepresented on Bing. Microsoft mobile share is genuinely lower than Google's; this isn't reporting bias.
3. YouTube as a complementary channel
Google Ads gives you YouTube. Microsoft has no comparable video inventory. For brands where video is core (DTC consumer, education, fitness), Google is non-optional.
4. Best-in-class machine learning
Smart Bidding, Performance Max, and value-based bidding all have a ~2-year lead on Microsoft's equivalents. For high-velocity accounts where the ML matters more than CPC, Google's advantage is real. Microsoft is closing the gap fast — but in 2026, Google's algorithm is still cleaner on the same data.
The four-question framework
Before we add Microsoft to an account, we run four questions:
- Does the audience profile fit? If >60% of the brand's target buyers are 25-40 mobile-first consumers, skip Microsoft. Otherwise, run it.
- Is Google already capped? If we're losing impression share to budget on Google with healthy CPA, Microsoft is the next dollar's home before raising Google budgets further.
- Is the AOV high enough to matter? Below $50 AOV, Microsoft's volume often isn't worth the management overhead. Above $200 AOV, it almost always is.
- Does the brand have LinkedIn audience signals? If we know our buyer's job title or industry, Microsoft's LinkedIn layering is too valuable to skip.
Three "yes" answers and we launch Microsoft as a parallel channel. Two "yes" and we test with 15% of Google budget. One "yes" or fewer and we focus on Google.
We run Microsoft Ads end-to-end.
From import + restructure to LinkedIn audience layering to Audience Network creative. Same operator as your Google account. From $1,350/month.
See Microsoft Ads service →The four campaign types we always launch on both
When we run both platforms, these structures get duplicated 1:1:
- Brand defense Search. Cheap, defensive, prevents competitors bidding on your brand. Roughly $20-50/month on Microsoft. Skipping this is leaving free conversions on the table.
- Non-brand high-intent Search. The bottom-funnel keywords ("buy [product]", "[service] near me", "[competitor] alternative"). Microsoft pulls these for 30-50% less CPC.
- Performance Max / Shopping. Both platforms have it. Same feed. Different audience. Both deserve a budget tier.
- Retargeting via Audience Network. Microsoft Audience Network for pixel-based retargeting is cheap mid-funnel — pairs well with Meta retargeting for additive reach.
The fifth campaign type — generic awareness / category education — we do only on Google because Microsoft doesn't have the upper-funnel inventory to support it.
Frequently asked questions
Is Microsoft Ads cheaper than Google Ads?+
Yes — typical CPCs run 30-60% lower than Google for the same intent keywords. The reason is auction density, not audience quality. Microsoft has roughly one-third the search volume of Google, which means fewer bidders competing on each keyword, which pushes CPC down. That gap has been remarkably stable since 2018.
Is Microsoft Ads audience worse than Google's?+
Different, not worse. Microsoft's audience skews older (45+), higher household income (median 50% above Google), more desktop-heavy, and more enterprise. For B2B and high-ticket B2C, this is often a higher-converting audience than Google's. For impulse, mobile-first, or younger demographics, Google wins.
Should I run on Microsoft Ads if I already run Google Ads?+
In 2026, almost always yes. The platform import tool replicates a Google campaign in ~10 minutes. Starting budget can be 15-20% of Google spend; that's enough to validate whether the channel converts before committing more. The exception: if your product is genuinely a young or mobile-first niche (Gen Z fashion, mobile gaming) where Microsoft's audience doesn't fit.
Does Performance Max exist on Microsoft Ads?+
Yes — Microsoft launched Performance Max globally in 2024. It works mechanically the same way as Google's. In our experience the early data is noisier on Microsoft because there's less total inventory, but the same structural principles apply. We treat MS PMax as a complement to Search, not a replacement.
What share of clients should run Microsoft Ads?+
Across our portfolio, roughly 75% of accounts that run Google Ads also profitably run Microsoft Ads. The 25% that don't are usually consumer mobile, hyperlocal services, or Gen-Z brands where Microsoft's audience doesn't match. For B2B SaaS and high-ticket B2C, Microsoft frequently outperforms Google on CPA — it just doesn't scale as far in absolute volume.
Bottom line
If you're spending more than $5,000/month on Google Ads and not running Microsoft, you're almost certainly leaving 15-30% incremental profit on the table. The setup is one afternoon. The ROAS shows up in 30 days. The only real question is whether your audience profile fits — and for B2B, high-ticket B2C, and professional services, the answer is almost always yes.
If you'd like us to run the Google → Microsoft import + restructure for you, the Microsoft Ads service handles it as a one-time setup plus ongoing management.
