Google Ads, both ways: the real numbers in, cleaner conversions out.
Pull your Google Ads spend and performance into Polar, see inside Performance Max down to the asset group Google keeps hidden, and get true blended ROAS and CAC after the platform stops overclaiming. Then send Polar’s deduplicated, enriched conversions back to Google so Smart Bidding optimizes on real signal. One connection, both directions.

How to Connect Google Ads to Polar.
A Polar account with Shopify connected and a Google Ads account you can sign in to. For the deepest Performance Max tracking, plan to set the tracking template at the asset group level.
01 · What you need
A Polar account with Shopify
A Polar account with Shopify connected. This connector plugs in right next to your stack.
Connect your data →A Google Ads account
Access to the Google Ads account(s) you want to link, and one Google sign-in with every permission box checked.
Open Google Ads →Asset group tracking, for PMax
For the deepest Performance Max tracking, plan to set the tracking template at the asset group level. PMax asset groups do not pick up account-level suffixes automatically, and the setup flow walks you through it.
02 · Connect Google Ads, the easy way
1
Connect Google Ads ~2 min
One Google sign-in.
From Connectors, add Google Ads and sign in. Spend, impressions, clicks, CTR, conversions, and conversion value start flowing into Acquisition, blended metrics, and Creative Studio.
2
Turn on the deeper breakdowns ~5 min
Down to the asset group.
Polar pulls Google Ads down to ad group, ad, and asset group, including Performance Max, out of the default connector schema. For clean PMax attribution, set the tracking template or final URL suffix at the asset group level so the campaign detail lines up with what Polar reports.
Tip: connect Google Ads first for value the same day, then spend five minutes on the PMax asset group tagging. It is the single step that turns Performance Max from a black box into something you can actually manage.

See it in your reports the payoff
Blended, deduplicated, comparable.
Once the sync runs, Google Ads behaves like any other source and flows into your blended ROAS, MER, CAC, contribution margin, and any custom metric. Check Acquisition by channel and the Performance Max breakdown to confirm you see the asset group detail.
Side by side
Google Ads tells you Google Ads did great. Your business needs the real number.
Spend is scaling, Performance Max is eating more of the budget, and you still cannot see what is working inside it. And Google reports its own conversions on its own model, so the ROAS overclaims.

Performance Max is a black box. You see the campaign total, not which asset group, product, or audience is carrying it.
Performance Max broken down to the asset group Google hides, so you see where the spend actually goes.
Reported ROAS counts conversions your other channels also claim, so it overclaims and is not comparable.
Deduplicated ROAS after platform overclaiming is removed, comparable across every channel.
Brand searches get counted as new-customer acquisition, flattering PMax and hiding true CAC.
Brand and non-brand separated, so you see the real cost of net-new customers.
Google’s number lives in Google’s dashboard and never reconciles to contribution margin or net profit.
Every Google dollar reconciled into blended CAC, contribution margin, and net profit.
To move budget, you are trusting a platform that is grading its own homework.
And it runs the other way too: Polar sends clean, enriched conversions back to Google so Smart Bidding optimizes on better signal.
The Gap
The Google Ads connector is only half of it.
Data does not just flow into Polar from Google Ads. It flows back out to Google too. The CAPI Enhancer sends your enriched first-party conversions back server-side, so Smart Bidding optimizes on complete signal.
