Google Ads Accounts Hit Targets While Business Growth Stalls

Google's August 17 bidding update means budget-constrained campaigns using Target CPA and Target ROAS will now be pulled closer to their stated targets rather than significantly outperforming them. That change turns the number in the target field from a suggestion into an instruction, and Smart Bidding will execute it more faithfully than ever — even when the instruction no longer serves the business.

The core problem is structural: Smart Bidding is optimized to achieve its targets, not to grow the business. An ad account can consistently hit Target CPA or Target ROAS while revenue, profit, and overall business growth barely move. The algorithm keeps optimizing toward the goal it was given, even when that goal is no longer the bottleneck to growth.

Why does a healthy ad account fail to grow the business?

1. The target was never tied to margin. Most ROAS and CPA targets get set once and forgotten, drawn from historical performance, an industry benchmark, or a number that felt safe at the time. Few get revisited as COGS, shipping rates, overhead, product mix, or customer behavior shift. A 4.0x ROAS on a product line running a 20% margin produces a completely different financial reality than a 4.0x ROAS on a line running 60%.

2. The easiest conversions come from existing customers. Returning customers convert faster and cheaper than cold prospects, so bids drift toward them. The account hits every target on paper by repeatedly converting people who were going to buy anyway, and the customer base never expands.

3. Brand terms claim credit for existing demand. Branded search and retargeting campaigns post the best ROAS in the portfolio, yet much of that revenue would have arrived anyway through organic search, direct traffic, or existing demand. Reported ROAS climbs while true incremental revenue stays flat.

4. The conversion action is a proxy, not a sale. Lead-generation and B2B accounts frequently optimize for form fills, PDF downloads, or booked calls — signals, not revenue. The algorithm becomes exceptionally efficient at finding people who fill in forms, whether or not they buy. If closed-won data never flows back into Google Ads, the system can only count submissions, and a record month of conversions can coincide with a pipeline that produces nothing new.

5. Efficiency targets cap reach. Strict targets force the algorithm to sit out more expensive auctions, even when those auctions would produce profitable, net-new volume. The highest-growth opportunities are often more expensive than the easiest conversions. The ceiling sits in the account settings, not in the market.

6. Every conversion is treated as equal. When all conversions carry the same value, Smart Bidding cannot distinguish best customers from worst. Immediate-CPA bidding favors price-sensitive, low-tier buyers who convert easily and churn fast. For subscription and SaaS models, cheap acquisitions that cancel after month one drag company growth down while the account reports stellar efficiency.

7. The leak is downstream. Leads sit untouched for three days. Orders arrive for out-of-stock products. Onboarding stalls. Google Ads can only deliver demand to the front door; if revenue leaks between the conversion event and the balance sheet, no bid strategy will show it or fix it.

Where should marketers look first?

The platform does not prompt these questions, so the analysis has to come from outside it:

• Question the target: When was the current tCPA or tROAS set, and can anyone explain how it connects to current profit margins?
• Question the customer mix: What share of conversion value comes from new versus returning customers, and is that share stable or shrinking?
• Question the brand contribution: When non-brand spend rose in the past, did total business revenue rise, or did only platform numbers move?
• Question the conversion definition: Is the primary conversion action a real sale or something that merely might become one?
• Question the constraint: Is impression share being lost to rank on campaigns that are hitting target?
• Question what happens after the click: How fast are leads contacted, and what is the close rate versus other channels?

Hitting the target is not the goal

Success in Google Ads answers one question: did the account hit the target it was instructed to hit? Business growth answers a different one — whether that target still reflects what the business needs. Until someone compares Google Ads targets and conversion goals against actual financial results, the bidding algorithm can appear highly successful while growth remains flat.
