Microsoft Ads Call Tracking with msclkid Conversion Import

Why Microsoft Ads deserves call tracking too

Microsoft Advertising (formerly Bing Ads) captures 6 to 10 percent of search traffic in most markets, and the audience tends to skew older and higher-income. For industries like legal, home services, and financial services, Bing callers often convert at higher rates than Google callers. Without call tracking on Microsoft Ads, you are missing attribution data on a meaningful slice of your paid search performance. CallScaler tracks msclkid alongside gclid and fbclid for complete cross-platform visibility.

How msclkid tracking works

When someone clicks a Microsoft Ads search result, the URL includes an msclkid parameter. CallScaler's DNI script captures this identifier and stores it with the visitor's session. When the visitor calls your tracking number, CallScaler matches the call to the original Bing Ads click. The conversion is then posted back to Microsoft Advertising via their API. This is the same deterministic matching approach used for Google Ads gclid tracking, providing exact click-to-call attribution with no estimation or modeling.

Cross-platform reporting in one dashboard

See all your paid search call data in a single view:

• Google Ads, Microsoft Ads, and Meta Ads call conversions appear side by side
• Compare cost per call and lead quality across platforms in one report
• Identify which platform produces the highest lead scores for specific services
• Track keyword performance across Google and Bing simultaneously
• Export cross-platform data to CSV or Google Sheets for combined analysis
• Use unified reporting to make budget allocation decisions across all platforms

Conversion rules for Microsoft Ads

Apply the same quality filters to Microsoft Ads conversions:

• Set minimum call duration to filter out accidental dials and short calls
• Use lead score thresholds so only qualified calls feed into bid optimization
• Apply AI qualification rules based on actual conversation content
• Configure per-campaign rules if different Microsoft Ads campaigns need different criteria
• Duplicate call filtering prevents repeat callers from inflating conversion counts

Setup and verification

Connect your Microsoft Advertising account via OAuth from CallScaler's integrations page. The connection takes under a minute. Configure your conversion criteria (duration, score threshold) and CallScaler creates the conversion goal in Microsoft Advertising automatically. Verify the setup by checking the Microsoft Ads conversion tracking page where CallScaler-reported conversions will appear. From that point, every qualifying call from a Bing Ads click is reported as a conversion in real time, feeding Microsoft's automated bidding with accurate phone lead data.

Microsoft Ads for industries where Bing matters

Bing captures a disproportionate share of traffic in certain demographics and industries. Desktop users, older demographics, and users of Microsoft Edge default to Bing search. For industries like legal services, home improvement, and financial planning, Bing callers often convert at higher rates because the audience tends to have higher income and stronger buying intent. Tracking these calls with the same precision as Google Ads ensures you do not undervalue this channel.

Unified conversion rules across platforms

Keep your conversion criteria consistent across ad platforms:

• Use the same minimum duration and lead score thresholds for Google, Microsoft, and Meta
• This ensures you are comparing platform performance on an apples-to-apples basis
• Adjust rules only when specific platforms produce systematically different call quality
• Review cross-platform conversion data monthly to validate your rules are appropriate

When to invest more in Microsoft Ads

Signs that Microsoft Ads deserves more budget based on your call data:

• Average lead score from Bing is higher than Google for the same keywords
• Cost per qualified call is lower on Microsoft Ads due to less competition
• Connect rates are higher because Bing callers tend to be more intentional
• Your industry aligns with Bing's demographic strengths (professional services, B2B)
