Five GA4 tracking mistakes quietly costing you money

If your conversion data is wrong, every bidding decision is too. These are the errors we fix most often.

Smart bidding is only as smart as the data you feed it. In almost every audit we run, at least one tracking issue is distorting results — and costing real money.

Double-counted purchases

Running both a GA4 import and a native Google Ads tag for the same conversion is the most common culprit. Pick one primary source and stick to it.

Missing enhanced conversions

Enhanced conversions recover a meaningful share of conversions lost to cookie restrictions. It takes an hour to set up and pays back immediately.

Fix the measurement first. Then optimise.

No offline conversion data

For lead-gen businesses, importing qualified leads and sales back into Google Ads lets the algorithm optimise for revenue rather than form fills.
