Is Microsoft Advertising Worth the Investment?

Most B2B marketing budgets go straight to Google Ads without a second thought. Google dominates paid search. That dominance has created a blind spot. Microsoft Advertising, the platform formerly known as Bing Ads, reaches a professional audience that many B2B advertisers are ignoring entirely. Priority Pixels provides Microsoft Ads management for B2B businesses. The conversations we have with companies considering the platform almost always start with the same question. Is it worth the investment? Or is it just a smaller version of Google that doesn’t justify the effort?

The short answer is that Microsoft Advertising is worth it for the right B2B campaigns, but not because it does the same thing as Google at a smaller scale. It offers something different. Lower cost per click, access to LinkedIn targeting data and an audience demographic that skews older, more affluent and more likely to hold decision-making roles within their organisations. Those characteristics matter a lot when you’re selling to other businesses rather than consumers.

Why B2B Advertisers Overlook Microsoft Advertising

The perception problem is straightforward. Google processes the vast majority of search queries in the UK, so advertisers naturally default to Google Ads as their primary paid search channel. Microsoft’s share of the search market is smaller. That smaller volume makes it easy to dismiss. The thinking goes that if fewer people search on Bing, fewer potential customers will see your ads. On the surface, that logic seems reasonable.

What it misses is who those searchers are. Microsoft’s search engine is the default on every Windows computer, every Microsoft Edge browser and every device where the user hasn’t gone out of their way to change their search settings. In corporate environments where IT departments control device configurations, that default sticks. The result is a search audience with a disproportionately high concentration of professionals using work devices during business hours. For B2B marketers, that’s exactly the audience you want to reach.

The other factor working against Microsoft Advertising adoption is the name change itself. “Bing Ads” was a clearer description of what the platform did. “Microsoft Advertising” is broader, reflecting the platform’s expansion into audience targeting, native advertising through the Microsoft Audience Network and integrations across Microsoft’s product ecosystem. But the rebrand confused some advertisers who still think of it as just Bing search ads. Others assumed the name change signalled a shift away from search entirely. It didn’t. Search campaigns on the Microsoft Search Network remain the core of the platform for B2B lead generation.

Lower Competition Translates to Lower Costs

The cost argument for Microsoft Advertising in B2B is hard to ignore. Because fewer advertisers compete for the same keywords, CPCs on the Microsoft Search Network tend to run lower than equivalent terms on Google. According to WordStream’s comparison of the two platforms, Microsoft Ads consistently deliver lower average CPCs across most industries. For B2B keywords where Google CPCs can be steep, particularly in software, professional services and financial sectors, the savings on Microsoft can be significant relative to the volume you receive.

Lower CPCs don’t automatically mean better return on investment. The value depends on whether those cheaper clicks convert at a comparable rate. What many B2B advertisers find is that Microsoft search traffic converts at similar or sometimes higher rates than Google traffic for the same keywords. The theory behind this is that Microsoft’s audience skews toward an older, professional demographic that is further along in purchase decisions. They’re not browsing casually. They’re searching on work machines during working hours, often with purchasing authority.

The comparison isn’t about choosing one platform over the other. Most B2B advertisers who get the best results from paid search campaigns run both. The question is how to allocate budget between them. Microsoft Advertising deserves a larger share than many B2B companies currently give it.

The LinkedIn Targeting Advantage

Microsoft acquired LinkedIn in 2016. The integration between the two platforms has given Microsoft Advertising a targeting capability that Google simply cannot replicate. Within Microsoft Ads, you can layer LinkedIn profile targeting onto your search campaigns, allowing you to adjust bids or restrict ad delivery based on a user’s job function, company size, industry and seniority level.

For B2B, this is a real differentiator. Imagine you’re running ads for an enterprise resource planning product. On Google, you bid on relevant keywords and hope the person searching is a decision-maker at a mid-sized company. On Microsoft, you can bid on those same keywords and increase your bids specifically when the searcher’s LinkedIn profile matches your ideal customer profile. A finance director at a company with 200 or more employees searching for “ERP software UK” would trigger a higher bid than a student researching the same term for a coursework assignment.

Microsoft’s documentation on LinkedIn profile targeting positions the feature as a way to combine intent data (the search query) with identity data (who the person is professionally). That combination addresses one of B2B paid search’s persistent challenges, namely that keywords alone don’t tell you whether the person behind the search has the authority or the need to buy what you’re selling.

Who Searches on Bing and the Microsoft Network

Understanding the Microsoft search audience is key to deciding whether the platform fits your B2B strategy. The Microsoft Search Network includes Bing, Yahoo (which Bing powers), AOL and DuckDuckGo, along with search partner sites. The combined audience is smaller than Google’s, but its composition is what makes it interesting for B2B.

Microsoft’s own audience data indicates that users of the Microsoft Search Network tend to be in higher income brackets and older age groups compared to the general internet population. A large proportion of these users are on corporate-managed devices where Bing is the default search engine through Microsoft Edge and Windows integration. They may also use Bing through Microsoft 365 products, Cortana and Windows search. These aren’t people who chose Bing over Google for philosophical reasons. They’re using the search engine that’s built into their work environment.

For B2B advertisers targeting mid-market and enterprise buyers in the UK, this audience profile aligns well with typical buyer personas. Decision-makers at established companies, professionals in finance, operations, IT and management roles, people who search during working hours on corporate hardware. The volume is lower than Google, certainly, but the proportion of searchers who match a B2B target audience is higher. That concentration means your ad spend goes further in reaching the right people, even if the raw number of impressions is lower.

Building Effective Microsoft Ads Campaigns for B2B

The practical mechanics of setting up Microsoft Ads campaigns will feel familiar if you’ve run Google Ads campaigns before. Microsoft Advertising even offers a direct import tool that pulls your Google Ads campaign structure, keywords, bids and ad copy straight into the platform. That import function saves time, but treating it as a finished campaign is a mistake. Google and Microsoft have different auction dynamics, different audience profiles and different performance patterns. A campaign imported without adjustment will underperform.

Start by reviewing your keyword bids after import. Because CPCs are generally lower on Microsoft, your Google bids may be higher than necessary. Overbidding wastes the cost advantage that makes the platform attractive. Set bids based on Microsoft’s own auction data and adjust from there. The Search Engine Land overview of Microsoft Advertising recommends treating imported campaigns as a starting point rather than a finished product, adjusting bids, budgets and targeting to reflect the platform’s specific characteristics.

Negative keywords are another area that needs attention. Search queries on the Microsoft network don’t always match the patterns you see on Google. Bing’s search query matching can be broader, meaning your ads may appear for terms that don’t match your intent. Review search query reports frequently during the first few weeks and add negatives aggressively to keep your spend focused on commercially relevant terms.

B2B campaigns on Microsoft Advertising perform best when they’re treated as a separate channel with its own optimisation cycle, not as a mirror of your Google Ads account. The audiences are different, the competition is different and the bidding dynamics require independent management.

Apply LinkedIn profile targeting to your highest-value campaigns. Layer job function and company size targeting onto campaigns for keywords with strong commercial intent. You won’t want to restrict targeting too narrowly on every campaign since that would reduce volume on a platform that already has less traffic than Google. But for your most expensive, highest-intent keywords, LinkedIn targeting helps ensure your budget reaches the professionals most likely to convert.

Common Mistakes That Waste Microsoft Ads Budget

B2B advertisers who try Microsoft Advertising and conclude it doesn’t work have often made one or more of the same mistakes. The platform has its quirks. Ignoring them leads to wasted spend and misleading performance data.

• Importing Google campaigns without adjusting bids, resulting in overpayment for clicks that should cost less on Microsoft
• Leaving the Microsoft Audience Network enabled by default when the goal is search-only lead generation, which mixes display-style native placements into search campaign data
• Neglecting search partner settings, where some partner sites deliver lower quality traffic that dilutes conversion rates
• Not applying LinkedIn profile targeting to high-intent B2B campaigns, which removes the platform’s strongest differentiator
• Comparing raw lead volume to Google without accounting for the smaller audience, rather than comparing cost per lead and lead quality
• Ignoring device targeting adjustments, since Microsoft’s audience composition on desktop versus mobile differs from Google’s patterns

The Audience Network opt-in is particularly worth watching. Microsoft includes the Audience Network by default in new campaigns, which means your search budget can be spent on native ad placements across MSN, Outlook and partner sites unless you specifically exclude it. For B2B lead generation where search intent drives conversions, separating search and audience campaigns gives you clearer data on what’s producing results. Semrush’s guide to Microsoft Advertising covers this distinction in detail, noting that audience and search campaigns serve different purposes and should be evaluated independently.

When Microsoft Advertising Delivers the Strongest Results

Not every B2B company will get the same results from Microsoft Advertising. The platform tends to perform particularly well in certain scenarios. Companies selling to mid-market and enterprise buyers see strong results because those buyers are disproportionately represented in Microsoft’s audience. Professional services, SaaS, managed IT, financial services and manufacturing are all sectors where the platform’s audience aligns well with the typical buyer profile.

Microsoft Advertising also works well as a secondary paid search channel for companies that have already maxed out their Google Ads budget at an efficient cost per acquisition. If your Google campaigns are hitting diminishing returns where additional spend increases CPA without proportionally increasing lead quality, reallocating some budget to Microsoft often produces better marginal returns. You’re reaching a different pool of searchers at lower costs rather than paying increasingly more for the same audience on Google.

The platform is less effective for B2B companies targeting very small businesses or sole traders, where the audience is more likely to use personal devices with Google as their default search engine. It’s also less suited to industries with extremely niche keywords that generate very low search volume on Bing, since the already-smaller audience may not produce enough impressions to test campaigns meaningfully.

Getting Started With the Right Approach

The most sensible approach for B2B companies new to Microsoft Advertising is to start with your best-performing Google Ads campaigns. Import the campaign structure, then adjust bids downward to reflect Microsoft’s lower CPCs. Enable LinkedIn profile targeting on your highest-value ad groups. Exclude the Microsoft Audience Network initially so your data reflects pure search performance. Run the campaigns for 60 to 90 days before making any judgement about whether the platform works for your business.

Budget allocation varies by company, but a common starting point is to allocate somewhere between 15% and 25% of your total paid search budget to Microsoft. That gives the platform enough spend to generate meaningful data without overcommitting before you’ve seen results. As you gather conversion data, you can adjust the split based on actual cost per lead and lead quality comparisons between the two platforms. Some B2B companies end up shifting a much larger proportion of budget to Microsoft once they see the cost and quality advantages for their specific audience.

The investment question has a clear answer for most B2B organisations. Microsoft Advertising is worth testing. For companies targeting professional, mid-market or enterprise audiences in the UK, it’s often worth running as a permanent part of the paid media mix. The combination of lower costs, LinkedIn-powered targeting and a professional audience demographic gives it a distinct role that Google Ads alone doesn’t fill. Priority Pixels manages Microsoft Ads campaigns alongside SEO and organic search strategies to make sure paid and organic efforts work together rather than operating in isolation. The companies that get the most from the platform are those that commit to running it properly, with independent optimisation, rather than treating it as an afterthought that mirrors their Google account.
