Google Ads vs Microsoft Ads: What's the Difference?
Google Ads and Microsoft Ads are both search advertising platforms that show text ads when people search, but they run on different networks. Google Ads serves ads across Google Search and its partners, reaching the largest search audience by far. Microsoft Ads (formerly Bing Ads) serves ads on Bing, Yahoo, and AOL, plus partners, reaching a smaller but often older, higher-income, desktop-heavy audience. Microsoft Ads typically has less competition and lower cost per click, while Google Ads offers far greater reach and volume, so many businesses run both.

What these two platforms are #
Google Ads and Microsoft Ads are the two major search advertising platforms, both letting businesses bid to show text ads when people search for relevant terms. When someone types a query, an auction decides which ads appear and in what order, and advertisers typically pay only when someone clicks. The core mechanics are similar across both. The difference lies in where the ads appear. Google Ads shows ads on Google Search, which handles the vast majority of US searches, plus Google's search partners and other properties. Microsoft Ads, once called Bing Ads, shows ads on the Bing search engine and its partners, including Yahoo and AOL, and syndicated sites. Because search advertising captures people at the moment of intent, both can drive high-quality leads, which is why they anchor the paid work on our /services/google-ads-management page. Understanding how they differ helps a business decide where to spend, and often the answer is a thoughtful mix of both rather than one alone.
Reach and audience size #
The biggest difference between the two platforms is raw reach. Google dominates search, handling the large majority of US and global searches, so Google Ads puts you in front of by far the largest audience. If your priority is volume, reaching as many searchers as possible, Google is unmatched. Microsoft's search network is considerably smaller, which means fewer total impressions and clicks available. However, smaller does not mean insignificant; Microsoft's network still serves billions of searches and reaches millions of people, particularly through Bing being the default on Windows devices and Microsoft Edge. For many businesses, the Microsoft audience represents real, incremental customers they would otherwise miss. The practical implication is that Google should usually anchor a search campaign for reach, while Microsoft adds a valuable additional stream. Judging each by the leads and sales it produces, using the measurement discipline on our /services/analytics-tracking page, matters more than audience size alone, since a smaller audience that converts efficiently can still be well worth the spend.
Cost and competition #
Cost is where Microsoft Ads often shines. Because fewer advertisers compete on its network, the average cost per click tends to be lower than on Google for many keywords, and competition for ad positions is less fierce. For businesses on a tight budget, this can mean more clicks and conversions for the same money, or the ability to affordably compete on terms that are prohibitively expensive on Google. Google Ads, with its enormous demand, frequently sees higher costs per click, especially in competitive industries like legal or insurance. That said, cost per click is only half the story; what matters is cost per conversion and return on ad spend, which depend on how well each platform's traffic converts for your specific business. Microsoft's cheaper clicks are only a bargain if they turn into customers. Testing both and comparing true cost per acquisition, not just click prices, is the right way to judge, and it pairs naturally with the conversion focus on our /services/conversion-optimization page.
Audience demographics compared #
Beyond size, the two audiences differ in character, and this can matter for targeting. Microsoft reports that its network skews somewhat older, more affluent, and more educated on average, with a notable share of desktop and workplace users, partly because Bing is the default search on Windows and Edge in many business environments (Microsoft Advertising). This can make Microsoft Ads especially attractive for B2B services, higher-ticket products, or audiences that skew mature and professional. Google's audience, being the majority of all searchers, is broad and representative of the general population across every age and device. Neither profile is universally better; the right fit depends on who your customers are. A business selling to younger, mobile-first consumers may find Google's breadth essential, while one selling professional services to established buyers might see unusually strong returns from Microsoft. Rather than assuming, test both and look at which delivers your actual customers most efficiently. Demographic tendencies are a useful starting hypothesis, not a substitute for measuring real results in your own account.
Managing campaigns on each platform #
Operationally, the two platforms are more alike than different, which makes running both easier than it sounds. Both use keyword-based auctions, similar match types, quality signals, ad extensions, and automated bidding options, so skills transfer readily between them. Microsoft Ads even offers a direct import tool that copies your existing Google Ads campaigns, keywords, and settings, letting you launch on Microsoft quickly rather than rebuilding from scratch. This lowers the effort of adding Microsoft as a second channel considerably. Both platforms provide conversion tracking, audience targeting, and reporting, though the depth and exact features vary, with Google generally offering more tools and Microsoft catching up. For a busy small-business owner, the practical takeaway is that expanding from one platform to the other is not a major undertaking, especially with import tools. Whether you manage in-house or through a partner, as on our /services/google-ads-management page, the shared logic means expertise built on one platform applies largely to the other, easing the path to running both.
Which should a small business choose? #
For most small businesses, the honest answer is start with Google Ads and add Microsoft Ads once Google is working. Google's dominant reach means it should usually be the primary search channel, capturing the majority of searchers actively looking for what you offer. Get your Google campaigns profitable first, with solid tracking and strong landing pages from our /services/ppc-landing-pages page, before expanding. Then add Microsoft Ads, often by importing your Google campaigns, to capture incremental customers at frequently lower cost per click. This sequencing lets you prove the model on the bigger platform, then extend efficiently. There are exceptions: if you target professional, desktop, or older audiences, or find Google's competition too expensive, Microsoft may deserve earlier or heavier investment. The key is not to view it as either-or. Running both, sized to their returns, usually beats loyalty to one, because each reaches customers the other misses. Let measured cost per acquisition, not habit, guide how you split budget between them.
Measuring and comparing results #
Because the two platforms reach different audiences at different costs, you should measure each on its own true return rather than surface metrics. Set up conversion tracking on both so you know not just clicks but the leads, calls, and sales each produces, then compare cost per acquisition and return on ad spend side by side. A platform with a higher cost per click can still win if its traffic converts better, and a cheaper click is worthless if it never buys. Watch these numbers over enough time to gather meaningful data, since small budgets take longer to reach reliable conclusions. Use consistent UTM tagging and analytics, the discipline on our /services/analytics-tracking page, so both platforms report cleanly into one view and you can attribute results accurately. Reallocate budget toward whichever platform, campaign, and keyword delivers customers most efficiently, and keep testing. Treating Google and Microsoft as a portfolio to optimize, judged purely on measured outcomes, is how you extract the most value from running both.
Common misconceptions about the two #
A few myths cloud the Google versus Microsoft decision. The first is that Microsoft Ads is not worth it because its audience is small; in reality, that audience is real, often converts well, and frequently costs less per click, so dismissing it can leave efficient customers on the table. The second is the opposite error, treating Microsoft as a magic cheap alternative to Google; its lower click costs only pay off if the traffic converts for your business, which you must verify. Another misconception is that running both doubles the work, when import tools and shared mechanics make adding the second platform relatively light. Some assume whichever platform they use personally is what everyone uses, ignoring that their customers may search differently. Finally, many judge platforms on clicks or impressions rather than actual cost per customer, the only comparison that matters. Clearing up these misunderstandings leads to the sensible conclusion most experienced advertisers reach: use both platforms, sized to their measured returns, rather than betting everything on one.
FAQ
What is the main difference between Google Ads and Microsoft Ads?
Both show text ads when people search, but on different networks. Google Ads runs on Google Search, reaching by far the largest audience. Microsoft Ads runs on Bing, Yahoo, and AOL, reaching a smaller but often older, higher-income, desktop-heavy audience, usually at lower cost per click. Many businesses run both to combine reach and efficiency.
Is Microsoft Ads cheaper than Google Ads?
Often, yes. Because fewer advertisers compete on Microsoft's network, the average cost per click tends to be lower than Google's for many keywords. However, cheaper clicks only matter if they convert. Compare cost per acquisition, not just click price, since Microsoft's traffic must actually turn into customers to be a genuine bargain.
Should I use Google Ads or Microsoft Ads first?
Most small businesses should start with Google Ads because of its dominant reach, get campaigns profitable with good tracking and landing pages, then add Microsoft Ads to capture incremental customers at often lower cost. Microsoft even lets you import your Google campaigns, making expansion easy once your Google account is working well.
Can I run the same campaigns on both platforms?
Largely, yes. The platforms share similar keyword auctions, match types, and features, and Microsoft Ads offers an import tool that copies your Google Ads campaigns and settings. You should still review and adjust for each network's audience and costs, but you rarely need to rebuild campaigns from scratch to run both.
Who uses Bing and Microsoft Ads?
Microsoft's network reaches millions through Bing being the default search on Windows and Microsoft Edge, plus Yahoo and AOL. Microsoft reports its audience skews somewhat older, more affluent, more educated, and more desktop and workplace based, which can make it especially effective for B2B, higher-ticket, or professional-audience advertising. Test it against your own results.
Is it worth running both Google and Microsoft Ads?
For many businesses, yes. Google delivers the largest reach, while Microsoft adds incremental customers often at lower cost per click. Because the platforms share mechanics and Microsoft can import Google campaigns, running both is not much extra work. Size each to its measured cost per acquisition rather than treating it as an either-or choice.
