The article recommends not changing a single setting, pausing a campaign, or adjusting a bid until the audit is complete. According to groas, agencies should read backward through the last 90 days of change history and document every active campaign, its objective, its bidding strategy, and its last 30-day performance. Agencies should then cross-reference Google Ads conversion data against GA4 and the CRM and separate findings into quick wins for week one versus structural problems for the first 30 days.

The article states that conversion tracking is the foundation Smart Bidding uses to make spending decisions, and wrong tracking causes optimization toward wrong outcomes. According to groas, agencies should verify the GA4 property is linked and key events are firing, set up enhanced conversions using first-party data and verify flow in diagnostics, and for lead-gen pass back offline events with GCLIDs via CRM-to-Google Ads API connection. The article also recommends auditing consent mode implementation and prioritizing consent mode v2 if modeled versus observed conversion gaps are significant.

The article recommends picking one north star metric anchored to the business model and centering all reporting on it. According to groas, ecommerce clients need ROAS, lead gen clients need cost per qualified lead (not cost per form fill), and SaaS clients often need cost per pipeline opportunity or cost per demo. Secondary metrics can guide internal optimization, but the client should be anchored to one number agreed in writing.

The article treats the first 30 days as a data collection investment, not a performance window, because Smart Bidding needs approximately 30 to 50 conversions in a 30-day period to stabilize. According to groas, agencies should not start with target CPA or target ROAS if the account has no conversion history, and should instead start with Maximize Conversions (uncapped) or Manual CPC, then layer in targets once baseline data exists. If budget cannot support that volume, the article recommends consolidating conversion actions, starting with a higher-funnel event, or using manual CPC until enough data is collected.
