Is the conversion Google Ads optimises for the outcome the business actually values?

Only if your Primary conversion actions are restricted to real commercial outcomes. In our experience, accounts that have been handed between several agencies accumulate old goals over time, leaving minor page views, newsletter signups and duplicate tags active in the main Conversions column that Smart Bidding learns from.

What is the difference between Primary and Secondary conversion actions in Google Ads?

Primary conversion actions appear in the main "Conversions" column and are used directly by Google's automated bidding strategies to set bids and allocate budget. Secondary conversion actions appear only in the "All conv." column for observation and do not influence bidding (unless someone explicitly adds them to a custom campaign goal). We use Secondary actions to test new CRM and GA4 signals safely before switching live bidding over to them.

How do we move from bidding on raw form fills to bidding on qualified CRM leads without shocking our campaigns?

Never delete your existing Primary conversion action on day one. First, we set up your offline conversion tracking and B2B lead tracking as Secondary actions so we can verify that gclid and hashed lead details are matching cleanly in Google Ads diagnostics. Once the new qualified lead signal has consistent volume, we transition campaign bidding onto it in a controlled step.

Meanwhile, the sales director says the inbox is full of tyre-kickers, or the eCommerce manager points out that actual banked revenue hasn't moved. Nobody has necessarily falsified a report. What has happened is simpler and more expensive: **automated bidding is doing exactly what it was told to do, because someone fed it the wrong definition of a conversion.** ## A tag firing is not the finish line Google's Smart Bidding algorithms (Target CPA, Target ROAS and Maximize Conversions) do not understand your commercial margin or what a good trade enquiry looks like. They only optimise around whatever actions are ticked to appear in the main **Conversions** column of your Google Ads account. If your account marks a brochure PDF download, a "Click to view phone number" tap, or an unvalidated Submit button click as a **Primary conversion action** alongside genuine orders or quote requests, the algorithm treats all of them as wins. Because getting someone to click a PDF or fail a form validatio
