Google this week published updated documentation in its Help Center confirming that enhanced conversions for web and for leads will be merged into a single on/off feature starting in June 2026. The change, announced April 10, 2026, affects every advertiser currently using or planning to adopt enhanced conversions across the Google Ads platform.

The structural split between two separate enhanced conversions products - one for measuring on-site purchase and form completions, the other for tracking offline leads through CRM data - has existed since Google first launched enhanced conversions for leads in 2022. That distinction disappears under the new system. What replaces it is a unified status indicator with a simple toggle: on or off.

But the June 2026 change is only the second phase of a two-part rollout. The first phase is already in motion.

Multi-source data collection begins in April 2026

According to Google's updated Help Center documentation, starting in April 2026, Google Ads will simultaneously accept user-provided data from three distinct sources: website tags (such as the Google tag or Google Tag Manager), Data Manager, and API connections. Previously, advertisers were required to select a single implementation method. The new architecture removes that constraint entirely.

This shift matters because it changes the underlying data model. Rather than funnelling conversion signals through one pathway, Google Ads will now ingest hashed user data from all connected sources at the same time, with the system reconciling inputs internally. The stated goal is to improve conversion matching accuracy and, by extension, to feed more complete signals into Smart Bidding algorithms.

The data matching mechanism works by taking hashed customer information - typically email addresses, phone numbers, or physical addresses - submitted through one or more of those three channels and comparing it against Google's own data from consented, signed-in users. When a match is confirmed, the system attributes the conversion to the corresponding ad interaction. More input sources create more opportunities for a match to succeed, particularly in environments where a single data source might be incomplete or unavailable.

What the June 2026 change looks like in practice

According to Google's documentation, starting in June 2026, the distinction between enhanced conversions for web and enhanced conversions for leads will no longer appear in the Google Ads interface. The method selection screen - where advertisers historically chose between the Google tag, Google Tag Manager, or the API - will also be removed. In its place, advertisers will see a single unified setting.

The interface change will be visible at two levels. At the account level, enhanced conversions will appear under the Customer data use panel within Goals and Settings. At the individual conversion action level, the same toggle will be accessible when creating or editing a conversion action. Both pathways require acceptance of Google's Data Processing Terms before the feature activates. Advertisers who decline or have not yet accepted those terms cannot use enhanced conversions regardless of which interface path they take.

Existing users require no manual intervention. According to the documentation, anyone who has previously agreed to Google's customer data terms will be automatically migrated to the new unified status. The migration preserves active enhanced conversion configurations without requiring advertisers to reconfigure campaigns or re-establish data connections.

New advertisers who have never set up enhanced conversions can activate the feature at either the account or conversion action level. Opt-out remains available at the conversion action level at any time after activation.

The broader context: a pattern of consolidation

This change does not arrive in isolation. It reflects a measurable pattern in how Google has approached its measurement infrastructure over the past 18 months.

The Data Manager API, launched December 9, 2025, established a centralized ingestion point for first-party data across Google Ads, Google Analytics, and Display & Video 360 - consolidating what had previously been separate API implementations for each product. That launch was followed in January 2026 by a restriction on session attributes and IP address imports through the Google Ads API, pushing developers toward the Data Manager API as the designated infrastructure for complex conversion data. Then, on April 1, 2026, Customer Match uploads through the Google Ads API ceased functioning entirely, with all new Customer Match implementations required to use the Data Manager API.

The enhanced conversions unification follows the same logic: reduce fragmentation, reduce the number of integration decisions advertisers must make, and concentrate measurement signals into fewer but more capable pipelines.

On November 5, 2025, Google Analytics refocused its user-provided data feature on advertising conversions, shifting away from session attribution and toward enhanced conversions and Customer Match. That change improved the feature's accuracy for conversion purposes while removing its role as a reporting identity identifier. The April 2026 enhanced conversions update continues this directional shift.

The Google tag gateway for advertisers, which moved to general availability on May 8, 2025, added another layer to this infrastructure by routing Google tags through advertisers' own server domains, improving first-party cookie storage and reducing signal loss from browser-level tracking restrictions.

Why the removal of method selection is significant

The decision to eliminate method selection from the enhanced conversions interface is arguably the most technically consequential element of the update - more so than the visual consolidation of web and leads into one toggle.

Previously, the requirement to choose between the Google tag, Google Tag Manager, or the API created a decision point with real consequences. Advertisers who chose one method could not simultaneously benefit from another. An advertiser sending data via the Google tag could not also send data through the API without reconfiguring the setup. That constraint meant that if a primary data source degraded or became partially unavailable - for example, due to browser-level tag blocking or consent rate fluctuations - the system had no fallback.

Under the new architecture, all three channels operate concurrently. Google Ads accepts user-provided data from website tags, Data Manager, and API connections at the same time. The system is designed to handle overlapping or redundant submissions, using the available data to construct the most complete possible conversion picture.

For advertisers running campaigns with target ROAS or maximize conversion value bidding strategies, conversion data quality directly determines bidding performance. Incomplete or delayed conversion signals cause automated bidding systems to mis-estimate the likelihood and value of future conversions. Multi-source data capture reduces that risk by creating structural redundancy in the measurement pipeline.

Earlier work on the enhanced conversions infrastructure documented the differences between the web and leads implementations, noting that web-based enhanced conversions generally offered lower matching accuracy than the leads variant because the matching process depended more heavily on Google hashed user data. The leads implementation - which required advertisers to upload specific lead identifiers like email addresses from CRM systems - typically produced higher accuracy but demanded more ongoing maintenance. The unified system combines both data pathways, which theoretically narrows the accuracy gap while reducing setup overhead.

Compliance requirements and data terms

The activation of enhanced conversions carries a non-trivial compliance obligation. According to the Google Ads Help Center documentation, advertisers must confirm that the Google Ads Data Processing Terms apply to their use of enhanced conversions and that they will comply with Google's policies. This requirement applies regardless of whether activation occurs at the account level or the conversion action level.

The data terms acceptance process involves two steps in the interface: an initial agreement during setup and a second review and confirmation of the data processing terms. At the account level, this occurs within the Customer data use panel under Goals and Settings. At the conversion action level, the terms confirmation appears during the conversion action creation or editing workflow.

The compliance dimension is not peripheral. Enhanced conversions involve submitting hashed customer data - personal information that has been processed through a one-way hashing algorithm - to Google's servers for matching against user account data. The hashing renders the data unreadable in its submitted form, but the underlying personal data used to generate the hash remains subject to applicable privacy regulations in each jurisdiction. In the European Union, this implicates GDPR requirements around lawful basis for data processing, data subject rights, and data transfer obligations. The Digital Markets Act adds further layers for designated gatekeepers.

Account-level and conversion-level setup paths

For new users who have not previously configured enhanced conversions, the setup process follows one of two paths depending on the desired level of control.

At the account level: within the Goals menu, navigating to Settings and expanding the Customer data use panel reveals the option to turn on enhanced conversions. A separate option to turn on conversion-based customer lists is also present, allowing Google to use user-provided data to create customer lists based on conversions. Selecting Agree and save is followed by a second data terms review screen requiring a further confirmation. This account-level activation applies enhanced conversions as a default setting across all conversion actions in the account unless overridden at the conversion action level.

At the conversion action level: within the Goals menu, creating a new conversion action and selecting Conversions offline in the data sources panel provides access to the Customer data use settings. Enabling enhanced conversions and conversion-based customer lists at this step is followed by the same two-step data terms confirmation process. This pathway allows advertisers to enable enhanced conversions for specific conversion actions rather than applying it account-wide.

What this means for measurement strategy

The practical significance of this change extends beyond its immediate technical mechanics. It reflects a broader shift in how Google is positioning its measurement infrastructure as third-party tracking signals become less reliable.

Google's EC Assist Chrome extension, launched in July 2024, was an earlier attempt to reduce friction in enhanced conversions setup by guiding advertisers through troubleshooting steps. The April and June 2026 changes represent a more structural intervention - removing the complexity from the product itself rather than layering diagnostic tools on top of it.

The Google Analytics infrastructure update from November 2025 described early adopters on legacy infrastructure experiencing degradation in user-provided data functionality until migration to the updated system, expected to complete in Q2 2026. The enhanced conversions unification arrives in that same timeframe, suggesting a degree of coordination between the Analytics and Ads measurement infrastructure updates.

As detailed in PPC Land's coverage of the Data Manager API, the architecture emerging across Google's measurement products consistently points in the same direction: fewer integration points, unified schemas, and centralized data pipelines that handle complexity internally rather than exposing it to advertisers. The enhanced conversions change brings the same principle to the most widely used first-party measurement feature in the Google Ads platform.

For marketing teams managing large account portfolios, the automatic migration for existing users reduces the operational burden of the transition. For those not yet using enhanced conversions, the simplified activation path lowers the technical barrier to entry.

Timeline

Summary

Who: Google Ads, affecting all advertisers currently using or considering enhanced conversions across web and lead-generation campaigns globally.

What: Google is consolidating enhanced conversions for web and enhanced conversions for leads into a single unified feature with one on/off toggle, while simultaneously removing the requirement to choose a single implementation method. Starting April 2026, Google Ads accepts user-provided data from website tags, Data Manager, and API connections concurrently. Starting June 2026, the two separate enhanced conversion products merge into one.

When: The multi-source data acceptance begins in April 2026. The full interface unification - merging enhanced conversions for web and leads into a single feature and removing method selection - takes effect in June 2026. The documentation was updated and the change was announced on April 10, 2026.

Where: The change applies within the Google Ads platform globally, affecting both account-level settings under Goals and Settings and individual conversion action configurations. The unification will be visible in the Customer data use panel and throughout the conversion setup workflow.

Why: The unification reduces setup complexity and improves conversion signal resilience by allowing multiple data sources to operate simultaneously rather than requiring advertisers to select one. More complete conversion data improves the accuracy of automated bidding systems such as Smart Bidding, which rely on conversion signals to optimize campaign performance. The change also reflects Google's consistent direction across its measurement infrastructure - centralizing first-party data pipelines and reducing fragmentation across the Google Ads ecosystem.
