Microsoft Ads vs Google Ads cost comes down to reach per dollar in 2026: Bing handled 9.89% of US searches in September 2026 against Google’s 85.19%, according to StatCounter, and Alphabet’s latest 10-Q shows Google’s cost per click up 3% year over year. Neither Google Ads nor Microsoft Advertising sets a minimum budget or publishes an average cost per click, so for most advertisers the cheapest path is Google first, then a small Microsoft test built with Google Import.
How do Microsoft Ads and Google Ads compare on cost in 2026?
Both platforms charge per click through an auction, with no flat fee and no published minimum. The real cost difference is reach and labor: Google Ads reaches far more searches, while Microsoft Advertising adds Bing, Copilot and partner sites such as Yahoo, AOL and DuckDuckGo for a smaller extra budget.
Here are the four real options side by side. Reach figures are StatCounter’s US search engine share for September 2026. Cost signals come from Alphabet’s 10-Q for the quarter ended June 30, 2026, Google Ads Help and Microsoft’s Advertising API guide.
| Option | US search reach (StatCounter, Sept 2026) | Cost signals | Setup effort | Pick |
|---|---|---|---|---|
| Google Ads only | 85.19% of all searches; 94.13% on mobile | Paid clicks up 13%, cost per click up 3% year over year (Alphabet 10-Q); a day can spend up to 2x the average daily budget, a month no more than 30.4x | One account, one set of campaigns | Best for most small advertisers and any mobile-heavy local business |
| Microsoft Ads only | 9.89% of all searches; 18.8% on desktop; plus Yahoo, AOL and DuckDuckGo partner traffic | No published average CPC; overspend “usually” under 100% above the daily limit (Microsoft API guide) | One account, built from scratch | Rarely the right first channel; skip unless Google is already tested |
| Both, using Google Import | About 95% of searches across the two engines | Two media budgets; imported budgets can be raised or held at Microsoft levels | One import, then a second account to review every week | Best for advertisers whose Google campaigns already convert, especially B2B and desktop buyers |
| Neither | No paid search reach | $0 in media | None for ads; effort shifts to organic and earned visibility | Best when margins cannot cover a click or leads cannot be tracked |
The table points to one rule. Microsoft Ads is an add-on to a Google program that works, not a cheaper replacement for one.

What do the earnings filings say about Google and Microsoft ad prices?
Alphabet reports that Google Search & other paid clicks rose 13% and cost per click rose 3% in the second quarter of 2026. Microsoft reports search advertising revenue excluding traffic acquisition costs grew 12% in fiscal 2026. Neither filing gives an average click price, but both show which way prices are moving.
1. Google: more clicks, prices up slightly
Alphabet’s Form 10-Q for the quarter ended June 30, 2026 reports Google Search & other revenue of $63.27 billion, up from $54.19 billion a year earlier. Paid clicks rose 13% and cost per click rose 3% for the quarter; for the six months, the figures were 13% and 4%. Alphabet defines cost per click as click-driven revenue divided by paid clicks, a worldwide blend. The filing says it moves with device mix, geographic mix, advertiser spending and currency, so your keywords can rise faster or slower than that average.
2. Microsoft: a smaller business growing on revenue per search
Microsoft’s fiscal 2026 Form 10-K, for the year ended June 30, 2026, reports search advertising revenue of $15.18 billion, up from $13.88 billion, and says revenue excluding traffic acquisition costs grew 12% on “higher search volume and revenue per search.” On the fourth quarter call, CFO Amy Hood said ex-TAC growth was 10%, driven by “higher revenue per search across Edge and Bing,” and guided to mid-single-digit growth next quarter.
Two takeaways for a buyer. First, scale: Google Search earned more than four times as much in one quarter as Microsoft’s search advertising did in a full year, which suggests far more money competing in Google auctions. Second, Microsoft is raising revenue per search too. Treat any claim that Bing clicks are a fixed percentage cheaper with caution: Microsoft and Google do not publish one, and at least one page ranking for this query quotes a fixed gap without citing any source.
How much extra reach does Microsoft Ads add?
Bing adds about 10% of US searches on all devices, but almost 19% on desktop and about 2% on mobile, per StatCounter’s September 2026 data. That split decides whether Microsoft Ads is worth a budget, because the extra reach sits on work and home computers, not phones.
StatCounter’s September 2026 figures for the United States:
- All devices: Google 85.19%, Bing 9.89%, Yahoo 2.64%, DuckDuckGo 1.75%
- Desktop: Google 74.71%, Bing 18.8%, Yahoo 4.11%, DuckDuckGo 1.94%
- Mobile: Google 94.13%, Bing 2.15%, DuckDuckGo 1.57%, Yahoo 1.56%
Microsoft Advertising’s search ads page says ads can appear on Bing and “search partner sites such as Yahoo, AOL, DuckDuckGo, Ecosia, and other partners.” So the paid reach of a Microsoft campaign is larger than Bing’s share alone, though StatCounter does not report how much of Yahoo and DuckDuckGo traffic carries Microsoft ads.
Microsoft also publishes its own reach claims. Its search ads page states 6.4 billion monthly PC searches, 109 million unique PC users and a 38.1% PC market share in the US, footnoted to Comscore qSearch data from March 2023, desktop only. Those are Microsoft’s claims, three years old, measured on desktop across its network, so they are not comparable to StatCounter’s numbers. On the same fourth quarter call, Satya Nadella said Bing and Edge “have both taken share for five straight years.”
If your buyers search from office PCs, Microsoft reach is meaningful. If they search for an emergency plumber from a phone, Google covers nearly all of it.
What does it cost to run both through Google Import?
Running both costs a second media budget plus the hours to import and review a second account. Microsoft Advertising’s Google Import copies campaigns, ads, targeting and extensions from Google Ads, and can repeat the import on a schedule, so setup is fast. The ongoing review is where the real cost sits.
3. Import and keep the accounts in sync
Microsoft’s Google Ads Import guide says the tool imports “most supported campaigns, ads, targets, ad extensions, and other settings by default,” and can run once, daily, weekly, monthly or on an automatic schedule. It also warns that “not all information will be imported,” and the API connects one Google Ads account to one Microsoft Advertising account. Microsoft’s new advertiser FAQ adds that “some features don’t map perfectly between platforms.” Plan time to check conversion tracking, audiences and negative keywords after every first import.
4. Budgets and pacing work differently
Google Ads Help says a campaign “might spend up to twice your average daily budget” on a given day, but no more than 30.4 times that budget in a month. Microsoft’s budget guide calls the daily budget “a target” and says it “usually keeps overspend to less than 100% above your daily limit,” with a monthly limit built from the daily budget times the days in the month. The import guide lets you raise imported budgets by a set percentage or keep existing Microsoft budgets unchanged, so check budget levels before the first import goes live.
5. AI placements come along with both
Both platforms now place search ads inside AI answers, with no opt-out. Microsoft’s help page on ads in Copilot says eligible campaigns “are automatically opted in,” that search ads need a logo to qualify, and that it “does not currently support specific metrics for ads served in Copilot.” Google Ads Help says you “can’t opt out of serving ads in AI Overviews” and offers no segmented reporting for them yet. Microsoft also says AI Max for Search is on by default for new search campaigns and that Google Import carries AI Max settings over. Microsoft claims ads in Copilot drive “101% higher engagement” than standard search ads, from its own June to August 2025 data, which you cannot verify in your own reports.
When is Microsoft Ads not worth running?
Microsoft Ads is not worth running when your Google campaigns are not yet profitable, your buyers search mostly on phones, or your budget is too small to split. In those cases a second account adds management hours without adding enough reach to measure.
Specific situations where we would stay Google-only or run neither:
- Google is not converting yet. Importing a campaign that loses money on Google copies the problem to a second platform. Fix targeting and tracking first. Our post on whether Google Ads is worth it for a small business covers that test.
- Your customers are on mobile. Bing’s 2.15% mobile share means a local service that lives on phone searches gains little.
- The budget barely covers one platform. Splitting a small budget gives each account fewer clicks to learn from. This is our judgment, not a published threshold.
- Management is billed per platform. If an agency charges a separate fee for Microsoft, the fee can exceed the media. Our guide to Google Ads agency costs explains fee models to compare.
- Nobody tracks leads. Without conversion tracking on both platforms, you cannot tell whether Microsoft clicks are cheaper per customer or only cheaper per click.
How should you split a budget between Google Ads and Microsoft Ads?
Start Microsoft at a test budget of about 10% to 25% of your Google search budget, then move money toward whichever platform delivers a lower cost per lead. That range is our synthesis from StatCounter’s share data, not a published rule, and we have not tested it as a benchmark.
The math behind it: Bing’s 9.89% share is about 12% of Google’s 85.19% on all devices, and Bing’s 18.8% desktop share is about 25% of Google’s 74.71%. A Microsoft budget near those ratios matches the extra searches you are buying.
A simple sequence:
- Run Google Ads until at least one campaign hits your target cost per lead.
- Import that campaign into Microsoft Advertising, with budgets set to your test level.
- Add a logo extension so search ads qualify for Copilot placements.
- Compare cost per lead, not cost per click, after a full month of data.
- Keep, scale or pause Microsoft based on that number.
Paid search stops the day the budget does. Copilot and ChatGPT also answer buyer questions without an ad slot, drawing on what is published about you across the web. Earned coverage and citations are the work Subscribe PR does through its services, and it runs alongside a paid program rather than replacing it. If Copilot matters to your buyers, our guide on how to rank in Microsoft Copilot covers the organic side.
FAQ
Is Microsoft Ads cheaper than Google Ads?
Neither platform publishes an average cost per click, so no primary source confirms a fixed discount. Alphabet’s 10-Q shows Google cost per click rose 3% year over year in the second quarter of 2026, and Microsoft says its own revenue per search is rising. Bing auctions have fewer advertisers because Microsoft’s search business is far smaller, which can mean lower prices on some keywords. Test your own keywords in both planners before you assume savings.
What is the minimum budget for Microsoft Ads?
Microsoft Advertising does not state a minimum spend in its new advertiser FAQ; it says you can start with a small daily budget and scale up. Its API guide says the monthly budget must fall within an allowed range for your currency. Google Ads also has no flat fee or monthly subscription. On both platforms, the practical minimum is enough budget to buy the clicks you need to judge results.
Can I copy my Google Ads campaigns to Microsoft Ads?
Yes. Microsoft Advertising’s Google Import connects to your Google Ads account and copies most campaigns, ads, targeting and extensions. You can import once or schedule daily, weekly or monthly imports to keep accounts in sync. Microsoft warns that not everything transfers and some features do not map perfectly, so review conversion tracking, audiences, negative keywords and budgets after the first import.
Do Microsoft Ads show in Copilot?
Yes. Microsoft’s help page says eligible campaigns are automatically opted in to serve in Copilot, including search ads with a logo extension, Shopping and Performance Max product ads, and multimedia ads. Advertisers cannot opt out, placement is not guaranteed, and Microsoft Advertising does not yet report Copilot-specific metrics. Google has a similar rule for ads in AI Overviews, with no opt-out and no segmented reporting.
What share of searches does Bing have in 2026?
StatCounter puts Bing at 9.89% of US searches across all devices in September 2026, against Google’s 85.19%. On desktop, Bing’s share rises to 18.8%; on mobile it falls to 2.15%. Microsoft Ads also reaches partner sites such as Yahoo, AOL and DuckDuckGo, so a Microsoft campaign can reach more searches than Bing’s share alone, though no public source states how many.
Should a small business run both Google Ads and Microsoft Ads?
Only after Google Ads is profitable. A small business should first prove one Google campaign hits its target cost per lead, then import it into Microsoft Advertising at a test budget. If customers search on phones, Bing’s 2.15% mobile share makes the second platform hard to justify. If buyers are businesses searching from office computers, the 18.8% desktop share makes a test worth running.
The short answer
Think of Microsoft Ads as a desktop extension of a Google program that already works. Google Search earned $63.27 billion in one quarter on clicks that cost 3% more than a year earlier; Microsoft’s search advertising earned $15.18 billion in a year while reaching about one in five US desktop searches and very few phone searches. If your Google campaigns convert and your buyers sit at computers, import them and test. If not, stay Google-only or put the money into visibility that does not stop when the budget does.
