Chasing ROAS is costing you growth, here’s what to focus on instead

Return on ad spend, or ROAS, has been the headline metric for digital marketing for more than a decade. Marketers celebrate campaigns that deliver a 5:1 return, and executives often use ROAS as shorthand for performance. It looks simple. Spend $1, get $5 back.

The problem is that ROAS does not tell the whole story. By focusing too narrowly on this metric, businesses often make decisions that limit long-term growth.

The limits of ROAS

ROAS is transactional. It measures the immediate return from media investment, but it does not capture the bigger picture. High ROAS can be misleading if it comes at the expense of new customer growth, lifetime value, or brand equity.

For example, campaigns aimed at remarketing to existing customers almost always show strong ROAS. But if you are only targeting people who would have purchased anyway, are you really growing? On the other hand, prospecting campaigns that introduce new audiences may deliver lower ROAS in the short term but create much higher value over time.

What you risk by chasing ROAS

Neglecting acquisition
Focusing too heavily on ROAS can bias spend toward easy wins with existing customers. This ignores the need to bring in new people continually.

Undervaluing brand activity
Top-of-funnel awareness campaigns rarely look efficient on a ROAS report, but without them, the pipeline dries up.

Missing lifetime value
Customers acquired through low-ROAS campaigns may have higher retention or higher average spend later on.

Overlooking the funnel
ROAS does not measure the health of your funnel or how well you convert people once they engage.

What to focus on instead

Customer acquisition cost and lifetime value
The balance between what it costs to acquire a customer and what that customer is worth over time is the ultimate growth equation. By looking beyond the first transaction, you can understand whether your marketing is building sustainable value.

Funnel conversion efficiency
How effectively are you moving people from awareness through to action? Instead of only asking how much a campaign returned, ask where prospects dropped off, what content kept them engaged, and how each stage is performing.

Incrementality
Would those sales have happened without the campaign? Incrementality testing helps determine whether your marketing is driving new behaviour or simply capturing purchases that were already likely to occur.

Engagement and retention
To foster long-term growth, prioritise retention metrics like repeat purchase rates, average order value, and churn. These indicators often predict sustained success more accurately than short-term return on ad spend (ROAS). Marketing efforts focused on building customer loyalty generate compounding returns.

The growth mindset

The businesses that win in 2025 are not the ones chasing impressive ROAS screenshots. They are the ones balancing efficiency with growth, optimising the funnel, and investing in activities that may not pay off instantly but build value over time.

This requires courage to defend strategies that look less efficient in the short term, but it is precisely what boards and investors want to see. They want confidence that marketing is fuelling sustainable growth, not just delivering easy wins.

The bottom line

ROAS still has value, but it should not be the headline. The real story is in acquisition, retention, and long-term value. If you keep chasing ROAS alone, you will miss the bigger opportunity.
