Microsoft Ads (Bing): When It's Actually Worth Running

Microsoft Ads is rarely a primary channel and shouldn't be. It's the channel you bolt onto a working Google Search account to pick up cheaper conversions from an older, wealthier audience — plus the only search platform that lets you target by LinkedIn job title, company, and industry.

Who should run it: B2B SaaS, financial services, insurance, healthcare, professional services, enterprise software, and any business where the buyer is 40+ and uses a work laptop running Edge or Outlook. If your ICP is a director-level decision maker at a 500+ employee company, Bing's audience is disproportionately yours. The LinkedIn profile targeting overlay (job function, industry, company size) layered on top of high-intent search keywords is genuinely unique — no other search engine offers it.

Who shouldn't: DTC brands targeting Gen Z, mobile-first apps, anything with a young or low-income audience, and anyone running their first paid campaign. Bing's mobile share is roughly 3-4% of US search vs Google's dominance — if your conversions happen on phones, you'll struggle to spend meaningfully. Also skip it if your Google account isn't already profitable. Microsoft Ads amplifies what works on Google; it doesn't fix what doesn't.

2025 benchmarks worth knowing:

• Search CPCs: typically $1.50-$6 across most B2B categories, vs $3-$15 on Google for the same keywords
• Insurance, legal, finance: $8-$25 CPC (still 30-40% under Google)
• B2B SaaS conversion rates: 2-5% on search, comparable to Google
• Audience Network (native placements): $0.50-$2 CPC but quality varies wildly — exclude aggressively
• Account import from Google: completes in under 10 minutes, syncs daily if you let it

The signature use case: mirroring your best Google Search campaigns at 25-40% of the budget. Same keywords, same ad copy, same negatives. You're not building a Microsoft strategy from scratch — you're harvesting the 7-12% of US desktop search Google doesn't own, at materially lower auction pressure. For a B2B account spending $10K/month on Google, expect to deploy $2,500-$4,000/month on Microsoft profitably before hitting volume ceilings.

Tradeoffs vs Google: Lower cost, lower volume, weaker automation. Microsoft's Smart Bidding works but lags Google's by roughly 12-18 months in sophistication. Performance Max equivalents (PMax in Microsoft) underperform Google's version meaningfully — stick to Search and Shopping. Reporting is rougher, the editor crashes more, and audience sizes for remarketing build slower because of lower traffic.

Tradeoffs vs LinkedIn Ads for B2B: This is the comparison that matters. LinkedIn Ads charges $8-$15 CPC on sponsored content with weak intent signals (someone scrolling a feed). Microsoft Ads with LinkedIn profile targeting charges $3-$8 CPC on someone actively searching for your solution AND matching your firmographic filters. For most B2B demand capture, Microsoft + LinkedIn targeting beats LinkedIn Ads outright. Save LinkedIn for ABM and demand gen where intent doesn't yet exist.

Where the audience actually lives: US, UK, and Australia are by far the strongest markets — Bing has near-zero share in most of Europe and Asia outside Japan. Within the US, the user base concentrates in corporate environments where IT departments standardize on Edge, plus the over-45 home demographic. Average household income skews 15-20% higher than Google's. This is why financial services and luxury B2C (think wealth management, premium home services) often see better ROAS on Microsoft than Google despite the volume gap.

The honest summary: Microsoft Ads won't transform your business. It will quietly add 15-30% more conversions to a working B2B Google account at a lower blended CPA, with maybe 2 hours of setup time. That's the entire pitch.

Example

A managed IT services firm spending $8,000/month on Google Search at a $220 CPA imported their account to Microsoft and allocated $2,500/month. After 60 days: 14 SQLs at $178 CPA, with LinkedIn targeting filtered to IT directors at 100-1000 employee companies. Same ads, same keywords, 19% lower cost per qualified lead.
