Google Merges Enhanced Conversions: What Changes for B2B Lead Gen

On April 10, 2026, Google updated its Ads support documentation to confirm a change B2B advertisers have been waiting on for years. Enhanced conversions for web and enhanced conversions for leads, which have operated as separate features since 2022, are being merged into a single on/off toggle. The rollout happens in two phases.

For the broader launch context behind this measurement change, see the GML 2026 pipeline launches that made closed-won feedback a prerequisite for new lead-gen formats.

Starting this month, Google Ads accepts user-provided data from website tags, Data Manager, and API connections simultaneously. Previously, advertisers had to pick one implementation method and stick with it. From June 2026, the interface itself changes: enhanced conversions becomes one toggle, method selection disappears, existing users auto-migrate if they have previously agreed to Google’s customer data terms.

For consumer e-commerce, this is a small quality-of-life update. For B2B advertisers running offline conversion imports from CRMs, it is the first meaningful simplification of the leads measurement stack since enhanced conversions for leads launched in 2022. Closed-won revenue data finally gets a default path to Smart Bidding.

What the Two Phases Actually Change

The change is narrower than most coverage makes it sound, but the narrow part matters.

In April 2026, Google Ads starts accepting user-provided data from three sources at the same time: website tags (the Google tag or Google Tag Manager), the Data Manager API (launched December 2025), and direct Ads API connections. Before this, the recommended pattern was to pick one method and commit. Mixed approaches were discouraged because they produced duplicate or conflicting signals. Starting now, parallel sending is supported natively.

In June 2026, the interface catches up. Enhanced conversions for web and enhanced conversions for leads, which today appear as two separately configured features, merge into a single on/off toggle at the conversion action or account level. Method selection (tag, Data Manager, API) disappears from the UI. Existing users migrate automatically if they have already agreed to Google’s customer data terms.

Why B2B Lead Gen Teams Benefit More Than Anyone Else

B2B lead gen teams have run a structurally harder version of enhanced conversions for three years. The reason: B2B conversions mostly close offline.

A B2B lead fills out a form on your site. Google Ads records a conversion. Three weeks later, sales closes the deal for $48,000. Google Ads has no idea that happened unless you import the closed-won signal back via enhanced conversions for leads, which required a separate setup, separate tags, and a separate decision about implementation method.

Under the unified toggle, the wall between “the form submission” and “the closed-won deal” comes down. Web tag captures the form fill, Data Manager API captures the closed-won push from your CRM, and Smart Bidding gets both signals against the same conversion action. The single toggle, set once at the account level, is the important part. Conversion value flows through with less configuration drift.

This matters alongside our earlier coverage of how B2B Google Ads budgets get wasted at scale. Smart Bidding without closed-won data optimizes for form fills, not revenue. The unified setup makes sending revenue data easier to configure and harder to break. For teams still sorting out which lead events should carry value, our B2B lead scoring criteria guide covers the scoring logic that should feed the Data Manager push.

What To Audit Before Google Migrates You

Google’s position is that no action is required. That is true only if your current setup is already clean. For B2B teams specifically, three things are worth checking now.

• Verify your conversion value import is actually running. A surprising number of B2B accounts have enhanced conversions for leads turned on, but the offline conversion push from the CRM stopped working months ago. Check your Google Ads conversion diagnostics report for any red or orange status on lead conversion actions.
• Confirm customer data terms are accepted. Auto-migration only works for accounts that have previously agreed to Google’s customer data terms. If yours has not, you will land on the unified toggle with enhanced conversions off.
• Decide whether you want Data Manager as the primary source. Google’s infrastructure direction is clear: the Data Manager API is the strategic ingestion point, not the Ads API. If you still send conversion data via the Ads API only, plan the migration now rather than retrofitting under deadline. This is part of a broader measurement shift we covered in our Google Analytics B2B setup guide.

The Broader Context: Google’s Measurement Consolidation

The enhanced conversions change follows a pattern that has been running for a year. In December 2025, Google launched the Data Manager API as a centralized ingestion point across Google Ads, Google Analytics, and Display and Video 360. In January 2026, Google restricted session attributes and IP imports through the older Ads API. On April 1, 2026, Customer Match uploads via the Ads API stopped working entirely; the Data Manager API became the only supported path.

The June 2026 toggle change applies the same playbook to enhanced conversions. Fewer integration points, unified schemas, centralized measurement. That direction helps B2B teams more than it hurts them, as long as the current setup is actually working. The urgency just sharpened: the May 20 Business Agent for Leads launch makes the closed-won feedback loop a prerequisite for the new Gemini-chat ad format to optimize on revenue rather than on qualified-lead count.

Our read: the teams that will benefit most are the ones who use the next 60 days to audit, not the ones who wait for auto-migration. A broken enhanced conversions setup before the toggle change becomes a broken unified setup after it. Google has not changed what needs to work. It has just reduced the number of places you can configure it wrong. LinkedIn’s parallel attribution fix in Off-Platform Event Ads follows the same pattern on the webinar side, removing the LinkedIn Event Page intermediary that used to break attribution between the LinkedIn click and the webinar platform’s attendee record.
