Most marketers still treat the Microsoft Ads vs Google Ads question as settled. Google is the plan. Microsoft is the leftover 5% of budget that somebody remembers to turn on in Q4. That framing costs money, and the numbers are not subtle about it.
According to WordStream’s 2026 Google Ads benchmarks, built from 13,474 US search campaigns between April 2025 and March 2026, the all-industry average cost per click on Google Search now sits at $5.42, with an average cost per lead of $66.69. Microsoft’s search inventory routinely clears at a fraction of that. Same intent. Same query. Different auction.
There is a name for why this keeps happening: the availability heuristic, the Kahneman-Tversky finding that we judge how important something is by how easily it comes to mind. Google comes to mind. Microsoft does not. That is a media-buying decision made by memory rather than math. Or, as Peter Thiel put it more bluntly: competition is for losers. The expensive auction is the crowded one.
This article does the math. Below you will find what each platform actually costs per click, who you are actually buying when you buy each audience, where Microsoft’s targeting genuinely beats Google’s, where Google still wins outright, and the budget split that works in practice rather than in theory.

The Cost Gap: What You Actually Pay Per Click
Start with the only number that shows up on the invoice.
WordStream’s 2026 data puts the average Google Search CPC at $5.42 across all industries, with cost per lead at $66.69. Microsoft’s search CPCs run meaningfully lower on identical keyword sets – agencies running parallel campaigns typically report 25% to 40% cheaper clicks, driven by one structural fact: fewer advertisers are bidding. Around 36% of US advertisers run Microsoft Ads, against roughly 80% on Google. Thinner competition, cheaper auction.
The cost per click on Microsoft Ads is not cheap because the traffic is worse. It is cheap because the room is emptier.
There is also a directional shift worth noting. WordStream flagged that for the first time in five years, average cost per lead across both Google and Microsoft Ads has gone down – a sign the paid search market is stabilising after years of compounding inflation. That makes this a better moment to expand into a second search channel than any of the last five.
One caveat before you get excited: cheaper clicks only matter if they convert. Which brings us to the audience.
Reach vs Relevance: Who You Are Actually Buying
Google wins reach. That is not in dispute and never has been. Bing holds roughly 9-10% of global desktop search and around 14% in the US per Statcounter, and Microsoft’s combined search partner footprint pushes that higher when Yahoo and AOL inventory are included.
But reach and value are different purchases.
Microsoft Advertising’s own audience data describes a search user who skews older, higher-income, and more likely to hold a management-level role than the average search user. The mechanism is unglamorous and reliable: Bing is the default in Windows, Edge, and Office, which means it captures a disproportionate share of people searching from a corporate desktop during working hours. That is a B2B buyer at their desk with a purchase order.
For a B2B SaaS, professional services, finance, or high-ticket ecommerce advertiser, that skew is the whole argument. You are not buying 10% of Google’s volume at a discount. You are buying a specific slice of the market that happens to be underpriced.
For a DTC brand targeting 22-year-olds on mobile, the same skew is a problem. Know which one you are.
Adcore’s team has covered the mechanics of this in more depth in this comprehensive guide to Microsoft Ads, which is worth reading alongside this comparison.
Targeting: Where Microsoft Advertising Beats Google
This is the part of the Microsoft Ads vs Google Ads comparison that gets skipped, and it is the part that actually matters for B2B.
LinkedIn profile targeting. Microsoft owns LinkedIn. That means you can layer company, industry, and job function targeting onto a search campaign natively. Google has no equivalent. If you sell to CFOs at logistics companies with 500+ employees, Microsoft lets you bid on a generic commercial keyword and only compete for the people who match that profile. That is a genuine structural advantage, not a feature-parity item.
Microsoft Audience Network reach. MSAN places native ads across MSN, Outlook.com, Microsoft Edge, and a partner publisher network Microsoft puts at over a billion users. It is a native inventory pool with no Google equivalent, and it is priced like display while behaving like content. We cover it properly in this breakdown of the Microsoft Audience Network.
Copilot placements. Microsoft has been pushing ad formats into Copilot surfaces, where sessions carry markedly higher commercial intent than a standard search session. This is early inventory. Early inventory is cheap inventory.
Practical import path. Microsoft’s import tools now pull campaigns from Google, Meta, and Pinterest. Testing Microsoft is a one-hour job, not a rebuild.
If you run an agency or affiliate operation and want that infrastructure without building it, Adcore’s Channel Partner Program handles Microsoft account setup, billing, and platform-level support for you.
Where Google Ads Still Wins
Anyone telling you to move budget wholesale off Google is selling something. Four places Google is still the correct answer:
Absolute volume. If your addressable market is small and you need every impression available, Google is where the queries are. Microsoft cannot backfill a volume gap.
Mobile and younger audiences. Google dominates mobile search and Android defaults. Microsoft’s desktop skew works against you here.
YouTube. There is no Microsoft equivalent for video at that scale. Full stop.
Local intent and Maps. For a multi-location retailer or service business, Google’s local pack and Maps integration are effectively a monopoly on “near me” intent.
The mistake is not choosing Google. The mistake is choosing only Google, then wondering why blended CPA keeps climbing every quarter. When a single channel is your entire acquisition engine, you have no leverage in its auction – you are a price taker.
If you are still deciding whether the second channel is worth the operational overhead at all, Adcore’s take on whether Bing Ads are worth it answers the objection directly.
The Budget Split That Actually Works
Here is the practical answer to Bing Ads vs Google Ads, stripped of platform loyalty.
Step 1 – Import, do not rebuild. Pull your top-performing Google Search campaigns into Microsoft using the native import. Do not touch the structure yet.
Step 2 – Start at 10-15% of search budget. Enough to generate signal inside a month. Small enough that a bad test does not damage the quarter.
Step 3 – Prune the imported junk immediately. Import carries over Google-specific settings that make no sense on Microsoft. Kill the search partner placements you cannot see performance for, and rewrite the ad copy – Microsoft’s audience is not Google’s audience.
Step 4 – Layer LinkedIn targeting on your B2B campaigns. This is the step people skip and the step that pays.
Step 5 – Judge on blended CPA, not channel CPA. The question is never “did Microsoft beat Google.” It is “did adding Microsoft lower what I pay for a customer overall.” Usually it does, because you are buying incremental volume out of a cheaper auction rather than re-buying the same clicks.
Adcore manages this expansion across 95,000+ ad accounts and $600M in ad spend in 40+ countries. If you would rather hand the platform mechanics to someone else and keep the strategy, that is what the Adcore Elite digital marketing agency exists for.
Conclusion
The honest verdict on Microsoft Ads vs Google Ads is that it was never a versus. Google buys you volume. Microsoft buys you a higher-income, higher-intent slice of the same demand at a lower clearing price, with LinkedIn targeting Google cannot match. Running one without the other means paying full price for all of your traffic.
If you want to take this further, start with a 10% budget test and one imported campaign – then measure blended CPA, not channel CPA. That single change in reporting is usually what makes the case internally.
