Microsoft Ads vs Google Ads for B2B SaaS
Google has far more search volume, so it is usually the first search channel to prove. Microsoft offers a different mix: a smaller audience, LinkedIn profile data for bids, and its own AI placements. For many B2B companies, the question is not which one, but when to add the second.
Should you run Microsoft Ads or Google Ads?
Start with Google if you are proving paid search for the first time, because it has more search volume to learn from. Add Microsoft once you know which searches produce qualified pipeline, and judge it on whether it adds pipeline you weren’t already getting.
How do Microsoft Ads and Google Ads differ?
| Google Ads | Microsoft Ads | |
|---|---|---|
| Search volume | Much larger | Smaller, often more desktop and work-time searches |
| B2B audience data | Limited professional data in search | LinkedIn company, industry, job function and seniority as bid adjustments |
| AI search features | AI Max for Search, ads in AI experiences | AI Max for Search (on by default for new Search campaigns), ads in Copilot |
| Setup | Build from scratch | Can import campaigns from Google |
| Conversion tracking | Google tag, offline conversion imports | UET tag, offline conversion imports |
Microsoft made AI Max for Search generally available in August 2026, switched on by default for new Search campaigns, as covered on AI Max for Search. That alone is a reason not to copy campaigns over without checking settings.
What does Microsoft offer that Google doesn’t?
LinkedIn profile targeting is the main difference for B2B. In search campaigns it adjusts bids for people at chosen companies, industries or job functions; it does not narrow who sees your ads (Microsoft’s LinkedIn targeting help). Details and limits are on LinkedIn profile targeting.
Is Microsoft Ads cheaper than Google Ads?
Clicks are often described as cheaper, but costs vary by keyword and market, and volume is lower. A cheaper click is only better if it turns into qualified pipeline at a similar rate. Compare the two on cost per qualified opportunity, tracked as shown on pipeline tracking. For Google cost drivers, see Google Ads cost.
Prove the searches on one engine, then extend them.
Use what works on Google as a starting point for Microsoft, then let Microsoft’s own data decide.
How do you run both without duplicating work?
Use Google as the source of tested keywords, ads and pages, then import into Microsoft and adjust: settings, bids, AI features and tracking. The steps and the settings to check are on importing Google Ads campaigns. Keep reporting separate so you can see whether Microsoft adds pipeline or just shifts it.
Frequently asked questions
Is Microsoft Ads better than Google Ads?
Neither is better in general. Google has more volume; Microsoft can add incremental B2B pipeline once your searches are proven.
Should I run Microsoft Ads and Google Ads together?
Often yes, once Google works. Import from Google, adjust settings and measure Microsoft separately.
Is Microsoft Ads cheaper per click?
Often described that way, but it varies. Compare cost per qualified opportunity, not cost per click.
Does Microsoft Ads have LinkedIn targeting?
Yes, as bid adjustments based on LinkedIn company, industry, job function and job seniority data.
Can I copy my Google Ads campaigns to Microsoft?
Yes, with Google Import. Review AI features, bids, budgets and tracking before campaigns go live.
Which has more AI features?
Both now use AI matching and generated assets. Microsoft also places eligible ads in Copilot automatically.
