Target CPA Is Changing. Maybe We Should Stop Chasing It.

There is something interesting happening with Target CPA in Google Ads right now, and I don’t think the most important conversation is actually about the change itself. There will always be a new bidding update, a new automation feature, a new recommendation in the interface telling us what Google thinks we should do. We will read the announcement, talk about what it means, adjust a few settings, and move on to the next update. But underneath all of that is a conversation I think we need to have more often: why are we so attached to a particular CPA number in the first place?

I understand why we like it. CPA is one of those metrics that feels wonderfully concrete. You spent $10,000 and generated 100 conversions, so your CPA is $100. It’s easy to explain to a client. It’s easy to put on a slide. It’s easy to compare month over month. And when that number goes down, everyone feels like we’re doing something right.

Except a lower CPA doesn’t necessarily mean the business is doing better.

That’s where things get messy.

I’ve seen plenty of accounts where everyone gets excited because the CPA dropped, only to discover that lead quality dropped with it. The account generated more inexpensive conversions, but fewer people who actually wanted the product or service. The sales team had more leads to work through, but fewer opportunities worth pursuing. Technically, the PPC report looked better. The business didn’t necessarily feel better.

And that’s the problem with allowing one metric to become the goal.

A Target CPA should give an account direction. It should help establish what we’re willing to pay for a conversion based on what that conversion is worth to the business. But somewhere along the way, advertisers started treating that target as a finish line. If we set a Target CPA of $100, then $101 becomes a problem. $110 becomes a bigger problem. $125 feels like something has gone terribly wrong.

But what if that $125 conversion is worth twice as much to the business?

Now what?

This is the part of PPC that doesn’t fit neatly into a dashboard. Sometimes you have to spend more to get better customers. Sometimes the most valuable searches are more expensive. Sometimes the market changes and the CPA that made sense six months ago doesn’t make sense today. Sometimes competitors enter the auction, demand shifts, or the business changes what it wants to sell. And sometimes the account is finally reaching customers it wasn’t reaching before.

The number can go up while the business gets better.

That doesn’t mean we should ignore CPA. Far from it. It means we should stop pretending that CPA can tell us the whole story.

Think about what actually happens after a conversion. A person clicks an ad, visits a website, and fills out a form. Google Ads records a conversion. But the business hasn’t necessarily acquired anything yet. Someone still has to answer the phone. Someone has to qualify the lead. An appointment might need to happen. A salesperson might need to close the opportunity. Eventually, that customer has to generate enough revenue to make the acquisition worthwhile.

The conversion is simply one point in that journey.

If we’re asking Google to optimize around that one point while the business evaluates success much further down the funnel, there is a disconnect. And no bidding strategy, Target CPA setting, or automated recommendation is going to magically solve a disconnect in our measurement.

This is why I think the Target CPA conversation is actually a really good opportunity for PPC teams to step back and look at the bigger picture.

Instead of immediately asking, “How do we get CPA back down?” we should sometimes be asking, “Why did CPA go up?” Those are very different questions.

Maybe conversion volume increased. Maybe the account entered more competitive auctions. Maybe lead quality improved. Maybe the business started attracting higher-value customers. Maybe the conversion tracking changed. Maybe the landing page improved. Maybe the sales team is closing more of the leads coming through.

Or maybe performance really did get worse.

We won’t know if we’re only looking at the number.

This is also why I get nervous when I hear someone say that an account “needs” to hit a certain CPA without any conversation about where that number came from. Was it based on actual customer economics? Historical performance? A business goal? A number someone picked because it sounded good? Was it based on what the company can actually afford to spend to acquire a customer, or was it simply based on what they would prefer to spend?

Those are not the same thing.

A business might want a $75 CPA. That doesn’t necessarily mean the market will consistently deliver profitable customers at $75. And if the real economics of the business support a $125 acquisition cost, forcing the account to $75 may actually restrict growth.

This is where good PPC management becomes less about pushing buttons inside Google Ads and more about understanding the business behind the account.

We have to know what a valuable customer looks like. We have to understand which conversions matter. We have to question whether the leads we’re generating are actually becoming customers. We have to look at revenue and profitability when that data is available. We have to understand what the sales team is seeing that the advertising platform cannot see.

Because Google can optimize incredibly well toward the signals we give it.

But it can’t make a business decision we haven’t defined.

That’s an important distinction as automation continues to take over more of paid search. The answer isn’t to fight automation or go back to manually controlling every bid. The answer is to get much better at telling the systems what actually matters.

And that means we may need to get comfortable with something that feels very uncomfortable in PPC: sometimes the right answer is not a lower CPA.

Sometimes it’s a higher one.

If I told you that an account’s CPA increased by 20%, your first reaction might be that something needs to be fixed. But what if I also told you that qualified leads increased, appointment rates improved, the sales team was happier with the leads, and revenue grew? Would you still want me to bring the CPA back down?

I hope not.

At that point, lowering CPA simply because the number is higher could actually be the wrong business decision.

This is why I don’t think the Target CPA conversation should be about whether Google is changing the way the setting works. That’s worth understanding, of course. We need to know how the platform is evolving and what those changes mean for our accounts.

But the more important conversation is what happens after we make the change.

Are we still measuring what matters? Are we giving Google the right signals? Are we evaluating the quality of the conversions we’re generating? Are we looking at what happens beyond the initial lead? Are we willing to let the data challenge the number we decided was “acceptable”?

Because the best PPC strategy isn’t necessarily the one with the lowest CPA.

It’s the one that understands what that CPA is buying.

And maybe that’s the real lesson here.

We’ve spent years teaching advertisers to ask, “What’s our cost per conversion?”

I think we should start asking a better question.

“What did we get for what we spent?”

That question is harder.

It requires more data, more context, and sometimes a much more uncomfortable conversation with the business.

But it’s also a much better way to manage PPC.
