Google is merging Enhanced Conversions for Web and Enhanced Conversions for Leads into a single toggle — launching June 2026. This simplification means you can now send both tag-based and API-based conversion data simultaneously. For teams running PWA install campaigns through Google Ads, this is a major upgrade: you can finally track PWA installs with the same precision Google gives to native app installs.

The timing matters. As Google phases out third-party cookies and tightens consent requirements with Consent Mode V2, first-party conversion data becomes the only reliable signal for campaign optimization. Enhanced Conversions is how you feed that signal to Google Ads.

What Is Changing with Enhanced Conversions

Currently, Enhanced Conversions exists as two separate features:

• Enhanced Conversions for Web: Sends hashed first-party data (email, phone) from your website conversion tags to improve conversion measurement accuracy.
• Enhanced Conversions for Leads: Matches offline conversion data (CRM events) back to the ad click that generated the lead.

Starting June 2026, Google merges these into a single toggle. Both Tag and API can send data at the same time — Google deduplicates automatically. This means you no longer have to choose between client-side tag tracking and server-side API tracking. You run both, and Google takes the best signal.

For PWA install campaigns, this solves a long-standing problem: PWA installs happen on the web (not through an app store), so they’ve always been web conversions. But the install-to-engagement journey has lead-like characteristics (delayed value realization). Now you can track both the initial install AND downstream engagement as connected conversion events.

Why This Matters for PWA Install Campaigns on Google Ads

If you’re running Google Ads campaigns (UAC, PMax, or Search) to drive PWA installs, your conversion tracking has likely been one of these:

1. Basic: A Google Tag fires on the “thank you” or post-install page → counts as a web conversion
2. Better: Enhanced Conversions for Web sends hashed user data to improve match rates
3. Best (now possible): Enhanced Conversions unified — tag fires at install + API sends engagement/revenue events later

The “best” option is now achievable with the single-toggle merge. Here’s what this unlocks:

• Better Smart Bidding signals: Google’s algorithm sees both the install AND the downstream engagement, so it can optimize toward users who actually use the PWA — not just users who click “install.”
• Improved ROAS tracking: If your PWA has in-app purchases or subscriptions, you can send revenue data via the API and Google attributes it back to the original ad click.
• Higher match rates: Running both Tag + API increases the chance Google can match the conversion to the click, especially when cookies are blocked or consent is limited.

Teams using Google UAC optimization and PWA vs native app campaigns will see the most immediate benefit from this upgrade.

How to Set Up Enhanced Conversions for PWA Installs (3 Steps)

Step 1: Configure the Unified Enhanced Conversions Toggle

In Google Ads, go to Goals → Conversions → Settings. After the June update, you’ll see a single “Enhanced Conversions” toggle (replacing the separate Web/Leads toggles). Enable it.

Then configure your conversion action for PWA installs:

• Conversion name: pwa_install
• Category: “Install” or “Sign-up” (depending on your flow)
• Value: Set a value if you know your average PWA user LTV
• Attribution model: Data-driven (recommended for PWA where install → engagement has a delay)

Step 2: Implement Tag-Side Tracking

On your PWA install page, fire a Google Tag conversion event when the user accepts the install prompt:

• Use GTM to listen for the beforeinstallprompt → userChoice accepted event
• Fire the conversion tag with hashed first-party data (email or phone if collected pre-install)
• This gives Google an immediate signal at the moment of install

Step 3: Set Up API-Side Engagement Tracking

Use the Google Ads API (or Measurement Protocol) to send downstream events:

• pwa_first_session — user opens the PWA from home screen for the first time
• pwa_day7_active — user is still active after 7 days
• pwa_purchase — user completes an in-app purchase (with value)

Google’s deduplication ensures these don’t double-count with your tag-side install event. The API events give Smart Bidding deeper signal about which ad clicks lead to valuable users — not just installs.

Optimization Tips for PWA + Enhanced Conversions

Once your tracking is live, here’s how to get the most from the unified system:

1. Use value-based bidding: If you can assign revenue values to PWA engagement events, switch from target CPA to target ROAS. Google will optimize toward high-value PWA users, not just high-volume installers.
2. Set conversion windows correctly: PWA installs often show value over 7-14 days (not immediately). Set your conversion window to 14 days minimum so Google’s algorithm captures the full engagement cycle.
3. Monitor the Enhanced Conversions diagnostics page: Google provides match rate and coverage metrics. Aim for >80% match rate — below that, you’re losing signal and Smart Bidding can’t optimize effectively.
4. Compare against Play Store installs: If you run parallel campaigns (some to PWA, some to Google Play), the unified Enhanced Conversions data lets you compare LTV between the two distribution methods. Teams typically see PWA campaigns delivering 1.2x the install rate at comparable CPI.

Summary: Unified Enhanced Conversions = Better PWA Campaign Performance

Google merging Enhanced Conversions for Web + Leads into one toggle is a practical win for PWA install campaigns. You get better tracking, better Smart Bidding signals, and better attribution — without choosing between client-side and server-side approaches.

Your action checklist:

• ✓ Enable the unified Enhanced Conversions toggle (available June 2026)
• ✓ Set up tag-side PWA install conversion tracking
• ✓ Implement API-side engagement and revenue event tracking
• ✓ Configure data-driven attribution with 14+ day windows
• ✓ Monitor match rates and aim for >80% coverage
