Microsoft Ads vs Google Ads is no longer just a comparison between a smaller, cheaper search platform and a larger one. Both now combine Search, Shopping, audience campaigns, Performance Max, and AI-powered automation, but they differ significantly in reach, professional targeting, inventory, and campaign scale. This guide compares the areas that matter most when deciding how to allocate your PPC budget.

Quick summary:

  • Google Ads offers much larger global search reach, while Microsoft Advertising adds access to Bing and Microsoft’s broader ecosystem.
  • Microsoft stands out for LinkedIn Profile Targeting, including company, industry, job function, and now job seniority.
  • Both platforms now support Responsive Search Ads and Performance Max, but their inventory and AI features differ.
  • Microsoft can complement Google Ads when you want additional reach, especially in B2B or desktop-heavy markets, but lower CPC should not be assumed without campaign data.
  • The best platform depends on audience, geography, conversion economics, and available budget, not platform reputation alone.

Key differences between Microsoft Ads and Google Ads

Both platforms have their own strengths and unique features. Here, we’ll explore the major 10 differences – Microsoft Bing Ads vs. Google Ads.

1. Audience reach and user context

Google still dominates global search usage. StatCounter measured Google at approximately 91.1% of worldwide search engine usage, compared with 4.5% for Bing. In the US, Google accounted for about 86.1%, while Bing reached 8.92%.

Microsoft Advertising still gives advertisers access to audiences beyond Bing itself, including Microsoft properties and selected search partners. This can make it useful as an incremental channel rather than a direct replacement for Google Ads.

2. Search volume

Google remains significantly larger in global search usage, which gives advertisers access to much greater potential query volume.

Google accounted for about 91.1% of worldwide search engine usage, compared with approximately 4.5% for Bing. The gap is smaller in the US, where Bing represented about 8.9% of usage.

For advertisers, this generally means Google offers more scale, while Microsoft can provide additional reach once Google campaigns are already capturing core demand.

3. Competition

Competition varies by industry, keyword, location, and audience, so one platform is not always more competitive than the other.

Google’s larger search volume can attract more advertisers in high-demand categories, while Microsoft may face less competition in some markets. However, advertisers should compare actual CPC and conversion costs rather than assume Microsoft is always less competitive.

4. Ad performance

Performance can differ significantly between Google Ads and Microsoft Ads, cross-industry search benchmarks show:

MetricGoogle SearchMicrosoft Ads
Average CPC$2.96 – $4.22$1.54
Average CTR3.52%3.10%
Average CVR4.40%2.94%
Average CPA$53.52$41.44

The data suggests that Google generated higher average CTR and conversion rates, while Microsoft showed lower average CPC and CPA in this benchmark. However, these are cross-industry averages, so actual results can vary significantly by market and campaign.

5. Cost

Microsoft Advertising can be more cost-efficient in some campaigns. In the same 2026 paid media benchmark report, Microsoft Ads recorded an average CPC of $1.54, compared with $2.96 – $4.22 for Google Search. Average CPA was also lower at $41.44 versus $53.52.

However, lower costs do not automatically mean better performance. Google’s higher search volume may generate substantially more conversions, while Microsoft can provide additional demand at a lower acquisition cost.

At Mega Digital, we have also seen how proper Google Ads optimization can keep acquisition costs low while driving stronger returns. For TV Outlet, a Netherlands-based online TV retailer, we combined Search Ads, Performance Max, and Shopping Ads with ongoing campaign optimization. The campaign achieved a $1.60 CPA and 3.2x ROAS, while the client reported revenue growing to nearly 4x its previous level.

This case shows that platform-level CPC is only part of the picture. Campaign structure, bidding, targeting, and optimization can have a much greater impact on the actual cost of acquiring customers.

6. Ad formats

Here’s a brief overview of the ad types you can run on Microsoft and Google:

Advertising areaMicrosoft AdvertisingGoogle Ads
Search AdsResponsive Search Ads, Dynamic Search Ads, Multimedia AdsResponsive Search Ads, Dynamic Search Ads
Shopping AdsShopping Campaigns, Product AdsShopping Campaigns, Shopping Ads
Display / Audience AdsDisplay Ads, Native Ads, Audience AdsDemand Gen
Performance MaxPerformance MaxPerformance Max
Video AdsVideo Ads, Connected TV AdsYouTube Ads, Demand Gen

Search Ads

Both Google and Microsoft mainly use Responsive Search Ads, where multiple headlines and descriptions are combined dynamically based on the search query. Microsoft also offers Multimedia Ads, adding visual elements to search placements.

Because the structure is similar, advertisers already running successful Google Search campaigns can adapt much of their messaging when expanding to Microsoft. This makes Search one of the easiest campaign types to test across both platforms.

Shopping Ads

Both platforms support Shopping campaigns that display product details such as images, prices, titles, and store information before users click. Microsoft uses Product Ads, while Google Shopping relies on product data submitted through Merchant Center.

Shopping Ads

In our view, feed quality often matters more than the format itself. Strong product titles, accurate attributes, competitive pricing, and clean product data can influence Shopping performance more than simply choosing Google or Microsoft.

Display Ads

Microsoft offers Display, Native, and Audience Ads across its own properties and partner inventory, while Google is moving more visual advertising into Demand Gen across YouTube, Discover, Gmail, Maps, and the Google Display Network.

These campaigns are usually more valuable for remarketing, audience expansion, and demand generation than for capturing immediate search intent. That is why we would not judge them only by CTR or direct conversions.

Performance Max

Both platforms now offer Performance Max, using automation to distribute ads across multiple placements and optimize toward conversion goals. Google has the advantage of a broader ecosystem, while Microsoft applies the same model within its own network.

Performance Max becomes much more useful once conversion tracking is reliable and the account has enough quality data. If those signals are weak, giving the platform more automation does not necessarily lead to better results.

7. AI and campaign automation

Both platforms now use AI more deeply across Search and cross-channel campaigns.

Microsoft introduced AI Max for Search in 2026, combining broader search-term matching, text customization, and final URL expansion. Google offers a similar AI Max approach for Search and continues expanding automation across Performance Max and Demand Gen.

For advertisers, the difference is becoming less about whether a platform uses AI and more about which inventory, audience signals, controls, and reporting tools each platform gives you.

8. Keywords

Google and Microsoft Bing both provide a keyword research tool, broad match and allow negative keyword targeting. However, the primary contrast between the two lies in the fact that Microsoft generally experiences significantly lower traffic volumes for keywords.

9. Targeting options

While some believe that targeting features are alike on both platforms, it’s worth exploring the specific niche options each platform provides before deciding where to launch your campaign.

Google Ads offers more ways to reach people, but Microsoft is better for B2B. With Microsoft’s LinkedIn Profile Targeting, you can choose who sees your ads based on their company, industry, or job, which is useful because people don’t always mention these things in their searches.

10. Language targeting

Google Ads supports advertising across a broad range of languages, but its Search language targeting is changing in September 2026. Search campaigns will no longer require campaign-level language targeting; Google will instead use the language of the ad, landing page, search term, and other user signals to determine eligibility.

Microsoft also supports multilingual campaign targeting, but availability varies by market and campaign format.

11. Campaign import

Microsoft Advertising lets advertisers import campaigns from Google Ads, which makes it easier to extend an existing Google campaign structure to Microsoft rather than rebuilding everything from scratch. Microsoft currently supports imports across multiple campaign types and can carry AI settings such as AI Max through scheduled Google imports.

Microsoft Ads vs Google Ads – which to choose?

Neither platform is automatically the better choice for every advertiser.

Choose Google Ads first when you need maximum search demand, broader international reach, or access to Google’s wider ecosystem across Search, Shopping, YouTube, Demand Gen, and Performance Max.

Consider Microsoft Advertising when you want incremental search volume, additional desktop reach, or professional targeting through LinkedIn attributes. It can also be a practical second channel once a Google Ads campaign already has proven keywords and conversion data.

For many advertisers, the better question is not “Google or Microsoft?” but “How much budget should each platform receive based on incremental profitable conversions?”

Mega Digital tip: If your budget is limited, don’t split spend across two platforms just for coverage. Prove that one channel can generate reliable conversions first, then test the second platform with enough budget to produce meaningful data.

FAQs about Microsoft Ads vs Google Ads

Is Microsoft Advertising always cheaper than Google Ads?

No. Microsoft may have lower CPCs in some auctions, but cost varies by industry, location, keyword, and competition. Compare CPA and conversion value rather than assuming one platform is cheaper.

Can I run Google Ads and Microsoft Ads at the same time?

Yes. Many advertisers use both, but splitting budget only makes sense if each platform receives enough traffic and conversions to evaluate performance properly.

Is Microsoft Advertising better for B2B campaigns?

It can be particularly useful for B2B because of LinkedIn Profile Targeting, which includes professional attributes such as company, industry, job function, and job seniority.

Final words

Your most effective strategy would be to combine both Microsoft Ads and Google Ads, and that’s a winning approach!

Now that you’re well-informed about the Microsoft Ads vs Google Ads discussion, which of these advertising networks will you choose to promote your brand?
