Google Ads integration

Google Ads in Polar: spend in, first-party signal out.

Connect Google Ads once and spend, delivery and campaign performance flow into Polar's blended ROAS, MER and CAC, next to Meta, TikTok and the rest. Then Polar's CAPI Enhancer sends first-party, de-duplicated purchase conversions back to Google via Enhanced Conversions, so Smart Bidding optimizes on signal that browser tracking loses to iOS, cookies and ad blockers.

blended CAC

Google Ads gives you Google's number. Your business is one.

Ads Manager reports Google's ROAS in isolation, before dedup, and it cannot see Meta, TikTok, Shopify or email. So the real question, “what did Google earn me this month, all in,” has no home. Polar is that home.

Google Ads on its own

  • ROAS is Google's number, before dedup, so it overclaims against your other channels.
  • Smart Bidding optimizes on browser signal that iOS, cookies and ad blockers erode.
  • No view of whether Google spend is actually incremental.
  • Nothing reconciles against your real P&L.

Google Ads with Polar

  • Blended ROAS and MER after platform overclaiming is removed, so the number is real.
  • The CAPI Enhancer feeds Google first-party, de-duplicated conversions via Enhanced Conversions.
  • Geo-based incrementality testing proves the incremental impact of Google spend.
  • Every Google dollar reconciled into blended CAC, contribution margin and net profit.

Featured Use Case

The signal Google lost, sent back.

The signal Google lost, sent back

Google's Smart Bidding is only as good as the conversions it can see, and browser tracking now drops a large share of them to iOS, cookies and ad blockers. With the CAPI Enhancer, Polar captures purchases first-party through its own Pixel, enriches them with order and customer detail, and sends them back to Google via Enhanced Conversions, server-side. Google's algorithm optimizes on the conversions that actually happened, not the fraction the browser survived, so match rates rise and bidding gets smarter. And because the same events power Polar's blended reporting, you finally see Google's ROAS deduplicated next to every other channel.

What makes it real

100% event delivery. Purchases sent server-side via Enhanced Conversions, so the conversions the browser dropped still reach Google.

Deduplicated ROAS. Google's ROAS after overclaiming is removed, blended with every channel, so you compare like for like.

Ask Polar, in plain language. “Compare Google's reported ROAS to blended, and show blended CAC with and without Google.” No SQL, no export.
