Google Ads vs. Microsoft Ads: Which Platform Is Best?

Two platforms take almost all of the pay-per-click budget in search: Google Ads and Microsoft Advertising. For a business buying traffic and leads, picking the wrong one wastes real money. Google’s reach is not in dispute. What most advertisers miss is that Microsoft’s network is a different audience at a different price, not a smaller copy of Google.

Below we compare the two platforms on audience, cost, and features, so you can decide where your budget belongs and whether it belongs in both places.

What is Google Ads?

Google Ads, formerly Google AdWords, is the leader in search engine marketing. It runs on the world’s most popular search engine, which gives advertisers access to a massive global audience actively searching for products, services, and information. That volume, plus a deep toolset, makes it the default choice for most marketers.

Key Strengths of Google Ads:

• Unmatched Reach: With billions of searches per day, Google offers the largest potential audience of any search network.
• Diverse Ad Formats: From search and display ads to video (YouTube) and shopping campaigns, the platform provides a wide array of options to reach users at every stage of the funnel.
• Advanced Tools & AI: Google invests heavily in AI-driven tools like Performance Max and smart bidding to automate and optimize campaigns.

What is Microsoft Advertising?

Microsoft Advertising, previously known as Bing Ads, is the PPC platform for the Microsoft Search Network. That network includes Bing, Yahoo, and AOL, plus partner sites. Its market share is smaller than Google’s, but it serves a distinct user base that can be highly profitable for the right advertiser.

Key Strengths of Microsoft Advertising:

• Lower Costs: Due to less competition, the average cost-per-click (CPC) on Microsoft Advertising is often significantly lower than on Google Ads.
• Higher-Quality Audience: The network tends to reach an older, more affluent, and more educated demographic, which can be ideal for B2B and high-ticket B2C products.
• Better Ad Positions: With fewer advertisers competing, it is often easier and cheaper to secure top ad positions, leading to better visibility.

Head-to-Head Comparison: Google vs. Microsoft

Here is how the two platforms stack up in the categories that decide where budget goes.

Market Share and Reach

Google is the clear winner on raw numbers, handling the vast majority of global search queries. Microsoft’s network still processes billions of searches per month, though, which is a real slice of the market and especially so in North America. Ignoring that audience leaves customers on the table.

Audience Demographics

This is where the platforms truly diverge. Google’s audience is broad and spans all demographics. Microsoft’s user base skews older, with a higher average income and education level. That makes it a strong channel for businesses selling to established professionals or a more mature customer base — and a poor one if your buyers are young.

Cost-Per-Click (CPC) and Competition

Competition is fierce on Google Ads, which drives up the average CPC across most industries. Microsoft Advertising generally has lower CPCs because fewer advertisers bid on the same keywords. That lets a business stretch its ad budget further and potentially earn a higher return on ad spend (ROAS). For more on budget allocation, read our guide on optimizing your ad spend.

Click-Through Rate (CTR) and Conversion Rates

Many advertisers report higher CTRs on Microsoft Advertising. Less competition and more prominent ad placements explain most of that. Conversion rates vary by industry, but a more targeted, high-intent audience can produce stronger conversion performance on Microsoft’s network.

Platform Features and Targeting

Google is usually first to roll out new features, especially the AI and machine-learning ones. Microsoft follows quickly and has shipped targeting options Google does not have, including the ability to target users based on their LinkedIn profiles. Microsoft also lets you import campaigns straight from Google Ads, so the cost of trying it is low. Either way, targeting starts with solid understanding keyword research.

Key Differences at a Glance

Here is a simple table summarizing the core distinctions between the two advertising platforms.

Feature	Google Ads	Microsoft Advertising
Primary Network	Google Search, YouTube, Gmail, Partner Sites	Bing, Yahoo, AOL, DuckDuckGo, Partner Sites
Audience Reach	Largest global reach	Smaller, but significant and distinct reach
Typical Demographics	Broad, covers all age groups	Slightly older, more affluent, B2B-focused
Average CPC	Higher	Lower
Competition	Very High	Moderate to Low
Key Advantage	Maximum volume and reach	Higher ROAS and less competition

Conclusion: Which Platform Should You Use?

Our position: this is not a one-winner question, and for most businesses the right answer is both. Where each platform is genuinely wrong is easier to state. Microsoft Advertising is wrong for you if you need maximum volume, because the network is smaller and cannot carry a campaign alone. Google Ads is the wrong place to spend your last dollar if you sell to older, affluent professionals and competitors have already bid your keywords out of reach — that budget works harder on Microsoft.

Expert Tip: Start with Google Ads to capture the largest possible audience and validate your keywords and ad copy. Then import your best-performing campaigns into Microsoft Advertising to capitalize on lower costs and reach a new, high-value audience segment. This hybrid approach maximizes your overall market coverage.

Use each platform for what it is actually good at and you end up with a more resilient, more profitable PPC program. If you want help running both, see our PPC campaign management services.

Frequently Asked Questions

Is Microsoft Advertising cheaper than Google Ads?

Usually, yes. Fewer advertisers bid on the Microsoft Search Network, and that lighter competition pushes the average cost-per-click below what the same keyword costs on Google. The same math makes top ad positions cheaper to hold. Your own numbers will move with your industry and keyword list, so treat the discount as a reason to test Microsoft rather than a rate you are promised.

Should I run ads on both Google and Microsoft?

For most advertisers, yes. The two networks reach different people, so running both widens coverage instead of splitting it. The order matters: start on Google Ads to find the keywords and ad copy that convert, then import those proven campaigns into Microsoft Advertising to pick up cheaper clicks and a separate audience. Run Microsoft on its own only when budget is tight and your buyers skew older and professional.

Can I import my Google Ads campaigns into Microsoft Advertising?

Yes. Microsoft Advertising has a built-in import that copies your Google Ads campaigns across, which is why adding the second platform costs so little effort. Treat the import as a starting point, not a finish line. Bids, budgets, and negative keywords still need adjusting for the Microsoft network, because competition and click costs there are not the same as on Google.

Who should not use Microsoft Advertising?

Anyone whose goal is maximum volume. The Microsoft Search Network is smaller than Google Search, so if you need the largest possible pool of searchers, Microsoft cannot carry a campaign by itself. It is also a weak fit when your customers skew young, since the network leans older. Use it as a second channel rather than a replacement for Google Ads.

Which platform is better for B2B advertising?

Microsoft Advertising has the edge. Its audience skews older, more affluent, and more educated, which is the profile of established professionals, and it lets you target users based on their LinkedIn profiles. Google Ads still belongs in a B2B plan for volume and for the ad formats Microsoft does not match, but Microsoft often returns more per dollar on B2B keywords.

Do ads get higher click-through rates on Microsoft Advertising?

Many advertisers report that they do. With fewer competitors in the auction, ads sit in more prominent positions more often, and prominence drives clicks. Conversion rates are a separate question and swing hard by industry, though a smaller, higher-intent audience can convert well. Compare click-through and conversion side by side in your own account before you move budget.
