Why High ROAS Targets Reduce Google Ads Volume and Revenue

Question 1

Why can raising my ROAS target leave me with less total revenue?

Accepted Answer

According to the article, raising the target cuts from the margin where growth lives because of diminishing returns: the first dollars capture the easiest conversions and each incremental dollar reaches slightly harder customers. The article’s example spends $50,000 per month for $200,000 in revenue at 4x ROAS, then after moving to a 6x ROAS target spends $25,000 for $150,000 in revenue. ROAS went up while the business lost $50,000 in monthly revenue and kept only the most efficient conversions.

Question 2

How does Smart Bidding change bidding when my ROAS target is too high?

Accepted Answer

The article states Smart Bidding is trying to hit the number it was given, not grow the business, so with a target ROAS of 600% it withdraws from any auction where predicted conversion value divided by predicted cost falls below that threshold. According to groas, that means it stops competing for high-intent queries where CPC is too high, avoids new audience segments where conversion data is sparse, reduces bids on competitive shopping auctions, and pulls back from top-of-page positions where click cost is higher.

Question 3

What should an ecommerce brand track instead of ROAS alone?

Accepted Answer

The article recommends tracking contribution margin after COGS, shipping, and returns, plus new customer revenue as a percentage of total ad-driven revenue. It states a 500% ROAS on a product with 20% margins is worse than a 300% ROAS on a product with 60% margins. If campaigns only generate revenue from existing customers, the article says the advertiser is paying for sales it would have gotten anyway.

Question 4

What should a B2B lead generation advertiser track instead of cost per lead?

Accepted Answer

The article recommends measuring cost per qualified lead, where “qualified” is defined by the sales team based on close rates, not by form fills. According to groas, advertisers should feed actual pipeline value and closed-won revenue back into Google Ads as offline conversions and optimize toward pipeline value, not lead volume.

Question 5

What should a SaaS advertiser track instead of ROAS on trial sign-ups?

Accepted Answer

The article states ROAS measured at the trial level is nearly meaningless for SaaS and recommends customer acquisition cost including all ad spend, lifetime value of acquired customers, and payback period instead. According to groas, a 90-day payback period at scale is worth far more than a 30-day payback period at a fraction of the volume.

Question 6

When should I use Max Conversion Value instead of target ROAS?

Accepted Answer

The article states target ROAS constrains volume by definition, while Max Conversion Value with a budget cap tells Google to get the most revenue possible within spend. It recommends Max Conversion Value as almost always the better strategy for accounts where the primary goal is growth, not margin preservation. Spend is controlled through the budget, not through an efficiency floor that shrinks the addressable market.
