Microsoft Ads (Bing) for Affiliate Marketing: Lower CPCs, Less Competition

Microsoft Advertising, formerly known as Bing Ads, is the paid search platform most affiliate marketers overlook — and that oversight is exactly why it works. Microsoft's search network powers Bing, Yahoo, AOL, and the default search on Microsoft Edge, and it's increasingly integrated into ChatGPT's search capabilities. While it holds a smaller share of the overall search market than Google, the audience is wildly favorable for affiliate offers. Microsoft's own data shows its searchers skew older, have higher household incomes, use desktop devices more often, and are 37% more likely to be in the market for tools and software than the average internet user. Those demographics convert well on affiliate products, and the lower competition means you pay significantly less for each click.

Cost per click on Microsoft Ads typically runs 30% to 50% lower than Google Ads for the same keywords. A keyword that costs $3.50 per click on Google might cost $1.75 on Microsoft Ads with comparable search intent. For affiliate marketers working with thin margins, this difference turns campaigns from breakeven on Google into clearly profitable on Microsoft. The tradeoff is volume — Bing's search market share in the US hovers around 10-12%, so you'll get fewer total impressions. This is why Microsoft Ads works best as a complement to Google Ads rather than a replacement. Run both, capture the cheaper traffic from Microsoft, and accept that Google will still drive the bulk of your impressions.

The account structure will feel familiar if you've used Google Ads: you create campaigns, which contain ad groups, which contain keywords and ads. Microsoft Advertising uses the same auction mechanics with a Quality Score system, bid-based Ad Rank, and similar match types. The terminology and interface are nearly identical, which is intentional — Microsoft makes it easy for advertisers to cross-list from Google. What's genuinely unique is Microsoft's audience data. Because Microsoft owns LinkedIn, you can layer professional demographics like job title, company, industry, and company size onto your search campaigns. No other search platform offers this level of B2B targeting precision, and for affiliate marketers promoting software, business tools, or professional services, this is a significant competitive advantage.

Setting up your Microsoft Advertising account takes about fifteen minutes. You'll provide business details, a billing method, and agree to Microsoft's advertising policies — which mirror Google's rules around affiliate content, bridge pages, and disclosure requirements. The platform offers a signup credit for new advertisers in most regions, typically $100 to $150 in matching ad spend after your first deposit. Claim this credit before you start spending, because it can cover your entire first week of testing. Before launching any campaigns, spend thirty minutes clicking through the interface, opening the Keyword Planner, and exploring the Audience Network section. Familiarity with where things are will save you hours of friction when you're mid-campaign and need to adjust a setting quickly.

The foundation of a profitable Microsoft Ads search campaign is the same as Google: bid on keywords that signal someone is close to buying. Phrases like "best antivirus software 2026," "QuickBooks alternatives," "Webroot review," and "NordVPN vs ExpressVPN" tell you the searcher is evaluating specific products and is one tab away from a purchase decision. Because Microsoft's audience includes more desktop-based business users, B2B and SaaS-related keywords tend to perform particularly well. Affiliate offers in categories like business software, financial services, professional tools, web hosting, and B2B subscriptions often see conversion rates on Microsoft Ads that rival or exceed Google, despite the platform's smaller overall volume.

Match types function identically to Google Ads: exact match for precise control, phrase match for moderate expansion, and broad match for maximum reach. Start every affiliate campaign with exact and phrase match only. Broad match on Microsoft, like Google, will burn your budget on loosely related searches before you have the conversion data to guide Microsoft's algorithm toward the right audiences. Build a strong negative keyword list from day one — include freebie terms like "free," "torrent," and "crack," informational-only modifiers like "what is" and "how does," and irrelevant intent signals like "jobs," "salary," and "DIY." A tight negative keyword list on Microsoft often has a larger impact than on Google because the smaller search volume means a single irrelevant match can eat a meaningful percentage of your daily budget.

Microsoft's killer feature for search campaigns is LinkedIn profile targeting. You can layer targeting by job function, company, industry, and company size directly onto a search campaign — meaning your ads only show to people who match both the keyword intent AND the professional profile you want. This is genuinely unique and unavailable on any other search platform. For affiliates promoting B2B tools, business software, professional courses, or SaaS products, this lets you filter out consumer searchers who match the keyword but would never convert on an enterprise offer. You can also use LinkedIn targeting as a bid modifier rather than a hard filter, increasing your bid when a searcher matches your target profile and decreasing it when they don't.

The bridge page requirement is the same as Google: never send paid traffic directly to an affiliate link. Microsoft's advertising policies require that your landing page provide unique content beyond a simple redirect or thin review. Your bridge page should include original writing — a real review, comparison, or buying guide — along with visible affiliate disclosure and clear merchant links. Write ad copy that pre-qualifies clicks: include specific pricing, feature names, or comparison language in your headlines and descriptions so browsers self-select before clicking. Microsoft gives you three headlines of 30 characters each and two descriptions of 90 characters each in Expanded Text Ads, plus Responsive Search Ads that work identically to Google's format. Use ad extensions aggressively — sitelinks, callouts, and structured snippets increase your ad's size on the page, improve CTR, and lower your effective CPC over time.

The Microsoft Audience Network is Microsoft's equivalent of the Google Display Network — a collection of native and display placements across MSN, Outlook.com, Microsoft Edge's new tab page, Yahoo, and thousands of premium partner sites. For affiliate marketers, the Audience Network serves two purposes: prospecting new audiences with interest and LinkedIn-based targeting, and retargeting visitors who clicked your search ad but didn't convert. The native ad format is particularly valuable because it blends into editorial content on sites like MSN's news feed, where users are already in a content-consumption mindset. Native impressions on Microsoft's network often cost half of what equivalent display impressions cost on Google, and click-through rates on well-designed native creative can reach 0.5% to 1%, compared to 0.1% to 0.3% on standard display banners.

Audience targeting on the Microsoft Audience Network uses a mix of in-market audiences, remarketing lists, LinkedIn profile signals, and custom audience segments. In-market audiences are Microsoft's predefined segments of users actively researching specific product categories — similar to Google's in-market audiences but with Microsoft's unique data signals from Bing search history, Outlook behavior, and LinkedIn activity. For affiliate marketers, in-market audiences in categories like "Software Comparison Shoppers," "Credit Card Evaluators," and "Business Service Researchers" are high-intent segments worth testing. Combine in-market targeting with LinkedIn profile layers for even tighter precision — for instance, showing a SaaS affiliate ad only to in-market software shoppers at companies with 50-500 employees.

Retargeting is where the Audience Network becomes essential for affiliate economics. Set up a remarketing list that captures everyone who visits your bridge page and then serve them Audience Network ads across MSN, Edge, and partner sites. Retargeting conversion rates typically run 2-4x higher than cold prospecting because you're reaching people who already read your review or comparison content and need one more touchpoint to convert. Set a frequency cap of 3-5 impressions per user per day so you stay visible without becoming intrusive. Use multiple creative variations in your retargeting campaign so users see fresh messaging rather than the same ad repeatedly. Image ads should use clean, high-contrast creative that reads quickly — Microsoft users often browse MSN on desktop with larger screens, so detailed imagery and readable text work better here than on mobile-first networks.

Video ads on Microsoft's network run on MSN, Edge, and partner sites, and represent an underused opportunity for affiliates. Skippable in-stream video ads let you tell a short story about your reviewed product, and because Microsoft's video inventory has less advertiser competition than YouTube, CPMs are typically 20-40% lower. For affiliate marketers with existing YouTube ad creative, repurposing those videos onto the Microsoft network is low-effort incremental reach. Keep videos under 60 seconds, lead with the problem your reviewed product solves, and drive viewers to your bridge page rather than directly to the merchant. The same compliance rules apply — video ads pointing to affiliate content must route through a landing page with unique value, not just a redirect.

The fastest way to launch Microsoft Ads is Microsoft's built-in Google Ads import tool. If you already run Google Ads, you can mirror your entire account structure — campaigns, ad groups, keywords, ads, extensions, and budgets — in under an hour. The import tool offers a one-time import or a recurring sync that automatically pulls new campaigns from Google on a schedule. Most affiliate marketers should use the one-time import for their initial launch, then manage Microsoft Ads independently from that point forward. A recurring sync sounds efficient, but it forces Microsoft Ads to mirror changes designed for Google's algorithm and audience, which often underperforms on Microsoft. Use the import to bootstrap, then optimize specifically for Microsoft's lower-volume, higher-intent environment.

Conversion tracking starts with installing the Universal Event Tracking (UET) tag on your bridge page. The UET tag is Microsoft's equivalent of Google's conversion tag — a snippet of JavaScript that fires events when users take actions on your site. Install it site-wide using Google Tag Manager for easier management. Then create conversion goals for the key events that matter for affiliate tracking: affiliate link clicks, form submissions if you capture emails, time-on-page thresholds, and scroll depth. If your affiliate network supports postback tracking, configure it to pass actual commission data back to Microsoft Ads. Without revenue data flowing into the platform, you're forced to rely on proxy metrics like affiliate link clicks to judge performance, which works but leaves money on the table because Microsoft's algorithm optimizes better when it can see actual conversions.

Optimization rhythm for Microsoft Ads should be slightly slower than Google because lower volume means you accumulate statistically significant data over longer windows. Where you might review a Google campaign every 3-4 days, review Microsoft campaigns every 5-7 days to avoid making decisions on too little data. Pause keywords that have spent 3x your target cost per acquisition without producing a conversion. Increase daily budgets on profitable ad groups by no more than 20% every 5 days — aggressive budget increases reset Microsoft's learning phase and tank short-term performance. Add new long-tail keyword variations whenever you see profitable search terms in your search terms report, and add negative keywords aggressively when irrelevant matches appear. A tight, clean account structure matters more on Microsoft than on Google because every wasted impression represents a larger percentage of your total volume.

Knowing when Microsoft Ads will outperform Google Ads for your specific offer is a skill that develops with data, but some patterns are reliable. B2B SaaS, professional services, financial products, insurance, web hosting, and business software consistently perform better on Microsoft due to the older, higher-income, desktop-heavy audience. Consumer categories that skew older — home improvement, medical devices, retirement products, and traditional media subscriptions — also tend to outperform on Microsoft. Categories that skew younger — trending beauty products, mobile-first apps, and social-native brands — will almost always underperform relative to Google and should receive a smaller budget allocation. Let your conversion data guide the mix. After 30 days of running both platforms, you'll have clear ratios of cost per acquisition between the two, and budget should flow toward whichever platform produces cheaper conversions for each specific offer.
