Google Ads ROAS Explained
By Adedon · Updated 2026-08-14
What does ROAS mean in Google Ads?
ROAS in Google Ads is conversion value divided by spend, using the values you pass in conversion tracking. Ecommerce and lead gen with offline values can use it. Accounts that only count form fills have no honest ROAS until they assign value. Platform ROAS is not profit: it ignores COGS, refunds, and management fees, and it uses Google’s attribution.
Value must be passed
Dynamic purchase value, or carefully assigned lead values, make ROAS possible. $1 placeholder values make ROAS a count of conversions in disguise. Do not Target ROAS on fake values.
Break-even ROAS is a finance number
Know margin and contribution. A ‘good’ ROAS is the one above your break-even after the costs you choose to include. Google cannot know that number unless you encode it in targets.
New customer versus returning
ROAS looks better when existing customers convert on brand terms. If growth is the job, look at new-customer value or non-brand campaigns separately.
PMax and ROAS
Performance Max will chase the value goal you give it, including easy brand value. Read ROAS with that in mind. Adedon will not treat a PMax ROAS screenshot as proof of incremental growth.
Frequently asked questions
Can I use ROAS for appointments?+−
Only if you assign a value that reflects expected revenue and close rate — and you revisit it. Otherwise use CPA for appointments.
Why is Google ROAS different from Meta ROAS?+−
Different attribution, different inventory, different conversion definitions. Compare each to your books, not only to each other.
Should I switch to Target ROAS immediately?+−
Not without value history. Maximize conversion value can be a bridge. Jumping to an aggressive ROAS target is a common way to stall delivery.
