Microsoft Ads (formerly Bing Ads) is Microsoft’s search advertising platform, serving ads across Bing, Microsoft Edge, Yahoo, and the Microsoft Audience Network. With over 1 billion monthly users across the Microsoft ecosystem, it gives performance marketers access to a high-intent search audience - often at lower competition costs than Google Ads - across verticals including finance, insurance, legal, ecommerce, health, and lead generation.

CPV One integrates with Microsoft Ads at three levels: it tracks clicks using parallel tracking (no redirects required), sends conversion events back to Microsoft Ads via the Microsoft Advertising offline conversions API, and pulls ad spend automatically via the Microsoft Ads API - so cost, CPA, and ROI in CPV One always reflect your actual spend.

The same integration works in CPV Lab (self-hosted version).

With this integration, you can:

• Track Microsoft Ads clicks and conversions inside CPV One in real time using parallel tracking - fully compliant with Microsoft’s no-redirect policy
• Send confirmed conversions back to Microsoft Ads via API so its algorithm can optimize audience targeting toward users who actually convert
• Automatically sync Microsoft Ads campaign costs via the API - no manual exports required
• Monitor real CPA and ROAS for your Microsoft Ads campaigns based on actual spend and conversion data
• Capture keyword, ad, and campaign tokens per click for granular performance analysis in CPV One’s drill-down reports
• Split test landing pages and offers against Microsoft Ads traffic and compare conversion rates in CPV One
• Compare Microsoft Ads performance alongside Google, Meta, TikTok, and all other channels in one dashboard
• Use your tracked Microsoft Ads data for AI automations and workflows via API

How it works

Microsoft Ads uses parallel tracking - meaning your ads link directly to your landing page, with tracking parameters appended via the Final URL Suffix field rather than through a redirect. CPV One supports this fully: you place CPV One’s tracking code on your landing page, and the parameters captured in the Final URL Suffix tell CPV One which ad, keyword, and campaign generated each visit.

When a visitor converts, CPV One records the event and forwards it to Microsoft Ads via the conversions API - tying the conversion to the original click and giving Microsoft’s algorithm the signal it needs to optimize audience delivery. At the same time, CPV One pulls your Microsoft Ads campaign spend automatically via the API, keeping your cost and ROI figures accurate across all reports.

For best results, CPV One recommends using a custom tracking subdomain based on your landing page domain - this ensures first-party data and cookie tracking work correctly across all browsers and devices, including mobile.

Why it matters

Microsoft Ads’ search audience is high-intent by nature - but without conversion data flowing back to the platform, its algorithm can’t optimize toward the users who actually buy or convert. It keeps spending on clicks without learning which ones matter.

Sending conversions via the conversions API closes that loop - Microsoft’s algorithm gets real purchase and lead signals, improves audience targeting, and brings you better traffic quality over time.

With CPV One tracking every Microsoft Ads campaign, you see true CPA and ROAS based on real spend and real conversions, and you can compare Microsoft Ads performance directly against Google, Meta, and every other channel you run - with the data to make confident scaling decisions.
