There’s one feature in Microsoft Advertising that has no equivalent on Google: LinkedIn audience targeting. Microsoft acquired LinkedIn in 2016 and built the integration directly into its advertising platform. You can now layer LinkedIn job title, industry, company size, and seniority data onto search campaigns — so you’re not just targeting what people are searching for, you’re targeting who those people are professionally.
I use this feature on almost every B2B and professional services account I manage. It changes the economics of paid search for businesses selling to specific job functions or industries. Here’s how it works and when to use it.
What LinkedIn Profile Targeting Actually Does
In Microsoft Advertising, you navigate to a campaign or ad group’s audience settings and add LinkedIn profile audiences. The options are:
- Job Function: Marketing, IT, Finance, Legal, Healthcare, Operations, etc.
- Industry: Software, Healthcare, Legal, Financial Services, Manufacturing, etc.
- Company Size: 1-10, 11-50, 51-200, 201-500, 501-1000, 1001-5000, 5001+
- Job Title: Specific titles like CFO, Marketing Director, IT Manager — this is the most granular option
When you add these audiences, Microsoft cross-references the searcher’s LinkedIn profile data against its Bing login data. The match rate isn’t 100%, but it’s substantial enough to shift campaign performance meaningfully in B2B verticals.
Bid-Only vs. Target and Bid
LinkedIn audiences in Microsoft Advertising can be applied in two modes. “Bid only” means the audience targeting layer adjusts your bids for matched users but doesn’t restrict who sees your ads — you still reach non-matched searchers, just at a different bid. “Target and bid” restricts your ad serving only to matched users — you’ll only show ads to people whose LinkedIn profile matches your specified criteria.
I always start with “bid only.” Apply a +20-30% bid adjustment for your target LinkedIn segments and run for 30 days. Review the performance data. If the LinkedIn-matched audience is clearly outperforming non-matched traffic, shift to “target and bid” for those segments. Jumping straight to “target and bid” restricts volume before you’ve validated the audience’s actual performance in your account.
When LinkedIn Targeting Changes the ROI Math
Here’s a real example from my work: I managed campaigns for a San Diego-based B2B SaaS company targeting HR directors. On Google, the campaigns were running at $95 CPA, which was above their target. On Microsoft Advertising with LinkedIn job title targeting for “HR Director” and “VP of Human Resources,” the CPA dropped to $52. The Bing volume was lower, but the lead quality was dramatically better — the leads were actually from HR directors, not people who happened to search HR-related terms.
The use cases where I’ve seen the strongest performance lift from LinkedIn targeting:
- B2B SaaS targeting specific buyer personas
- Legal services targeting in-house counsel or HR decision-makers
- Financial services targeting CFOs and business owners
- Recruiting and HR software targeting HR leadership
- Healthcare IT targeting hospital administrators
Company Size Targeting for Enterprise vs. SMB
Company size targeting is valuable for businesses that sell differently to enterprise vs. small business. If your product has an enterprise tier and an SMB tier with different price points and messaging, you can run separate ad groups with distinct copy — one emphasizing scalability and integration for 500+ employee companies, another emphasizing simplicity and cost for sub-50 employee companies. The messaging difference alone often lifts conversion rates significantly.
Combining LinkedIn Audiences with Search Intent
The real power of this feature isn’t just demographic precision — it’s the combination of intent (someone actively searching for a relevant term) plus professional identity (they hold a specific job title at a specific type of company). On Facebook, you can target HR directors, but you’re interrupting them while they’re browsing personally. On Microsoft Advertising with LinkedIn targeting, you’re reaching HR directors while they’re actively searching for a solution. That combination is uniquely valuable and unmatched on any other search platform.
What to Watch Out For
LinkedIn targeting works best in markets with enough LinkedIn users to provide meaningful match rates. In smaller geographic markets or very niche industries, the matched audience may be too small to meaningfully shift performance. Also, LinkedIn data isn’t always current — people don’t update their LinkedIn profiles immediately when they change jobs. Use “bid only” mode to stay safe and cast a wider net while still prioritizing your target personas.
If you’re running B2B campaigns and haven’t tested LinkedIn audience targeting on Microsoft Advertising, it’s one of the highest-leverage experiments available right now. Want help setting it up?

Frequently Asked Questions
What is LinkedIn audience targeting in Microsoft Advertising?
LinkedIn audience targeting lets you layer LinkedIn profile data — job title, industry, company size, and seniority — onto your Microsoft Advertising search campaigns. When a Bing user is also a LinkedIn member, Microsoft can match their professional profile to your targeting criteria and adjust your bid accordingly. It’s the only search advertising platform with this capability. Google has no LinkedIn data access, which makes this a genuine competitive differentiator for B2B and professional services advertisers on Bing.
How accurate is LinkedIn targeting in Microsoft Advertising?
Match rates vary but are meaningful. Microsoft doesn’t publish official match rate data, but in practice, campaigns in B2B verticals in major markets typically see 30-50% of impressions with LinkedIn profile data attached. The accuracy of the underlying LinkedIn data depends on users keeping their profiles current — seniority and industry tend to be more stable than job title, which changes more frequently. Despite imperfect match rates, the performance lift I’ve seen in B2B accounts is consistent and meaningful.
Can I use LinkedIn targeting for local service businesses on Bing?
Yes, but the use case is different from B2B. For local service businesses, I use company size targeting rather than job title — targeting business owners at small companies (1-50 employees) for commercial services, or professionals at larger companies for services targeting employed professionals. For consumer-focused local services, LinkedIn targeting is less relevant since the targeting is based on professional identity rather than consumer demographics. The feature is most powerful for businesses whose ideal customer can be defined by their professional role.
What’s the difference between LinkedIn targeting on Bing vs LinkedIn Ads?
LinkedIn Ads reaches users on the LinkedIn platform itself — feed ads, sponsored messages, InMail. Microsoft Advertising with LinkedIn targeting reaches LinkedIn members on Bing when they’re actively searching. The intent difference is significant: on LinkedIn, you’re interrupting people during professional networking. On Bing with LinkedIn targeting, you’re reaching the same people while they’re actively searching for something relevant to their work or business. The search intent makes Bing the stronger direct-response channel; LinkedIn’s platform is better for awareness and thought leadership.
How do I measure whether LinkedIn targeting is improving my Bing campaign performance?
Compare the performance of your LinkedIn-targeted audience segments against non-targeted traffic in the same campaigns. In Microsoft Advertising’s Audience Performance Report, you can see impression volume, CTR, conversion rate, and CPA broken out by audience segment. A successful LinkedIn targeting layer shows higher CTR and lower CPA for the matched audience compared to the baseline non-matched traffic. After 30 days of bid-only data, if your target LinkedIn segments are performing significantly better, shift to target-and-bid to concentrate budget on those users.
