A Google Ads campaign can be perfectly structured and still optimize badly if the conversion setup is sending mixed signals.
I saw this recently while auditing an account with 53 campaigns.
The account had three different Purchase conversion actions:
Purchase from GA4 Purchase from Website HubSpot customer import
And all three were showing “Needs attention.”
The bigger issue wasn't just the warning.
There was no clear conversion setup telling Google Ads which purchase signal should actually drive bidding.
That matters because Smart Bidding depends on the conversion data you give it.
If multiple sources are tracking the same purchase, you can end up with duplicate conversions.
If the wrong action is marked as Primary, campaigns may optimize toward a signal you didn't intend to use.
And if the underlying tag or import isn't working properly, the bidding system is learning from incomplete data.
So the first thing I worked on wasn't campaign structure or bid strategy.
It was the conversion setup.
I cleaned up the duplicate Purchase actions, kept the website Purchase as the clear Primary conversion, moved the GA4 and HubSpot versions to Secondary, and re-checked the tracking and Enhanced Conversions setup.
After the cleanup, the conversion actions were showing “Active.”
More importantly, the account had a much clearer data flow:
Website → Purchase → Google Ads → Primary conversion → Smart Bidding
This is something I think gets overlooked when people talk about improving ROAS.
Sometimes the problem isn't the campaign.
It's the signal the campaign is being optimized against.
And “conversion tracking is installed” isn't enough.
You also need to know:
Is the right conversion being counted?
Is it being counted once?
Is it marked Primary or Secondary for the right reason?
Is the value being passed correctly?
And is Google Ads actually receiving the signal consistently?
This is why I spend so much time auditing GA4, GTM, Google Ads and CRM conversion setups before touching the optimization side.
Bad conversion data can make a good campaign look bad.
If you're seeing “Needs attention”, unexpected conversion numbers, duplicate purchases or strange bidding behavior in Google Ads, feel free to connect or message me.
When was the last time you checked the status of your Google Ads conversion actions?
