Target ROAS
Paid MediaAlso: tROAS · Target Return on Ad Spend
Quick definition
Target ROAS (Return on Ad Spend) is an automated bidding strategy in platforms like Google Ads. You set a target ratio of revenue to ad spend and the algorithm adjusts bids in real time to try to hit that ratio, rather than you setting bids manually for each keyword.
Set this against your break-even ROAS, the point where ad spend just covers margin, not against a number that simply sounds ambitious.
How it varies across Australia
Target ROAS performs most reliably where conversion volume is high and conversion value tracking is clean. Australian accounts in narrower categories often struggle to stabilise a target because the weekly conversion count sits well below what larger markets generate. Consolidated campaigns tend to fare better than fragmented ones.

Target ROAS flips the usual bidding conversation. Instead of setting a maximum cost per click and hoping the return works out, you tell the algorithm what return you want and let it find the bids that get there.
Say the target is 400 percent, meaning $4 back for every $1 spent. The system studies your conversion value data and adjusts bids auction by auction, pushing harder where it predicts the ratio will hold and pulling back where it won't.
The catch is that Target ROAS needs enough conversion volume and clean conversion value data to learn from. Feed it a handful of sales a month and it will either miss the target constantly or throttle spend so hard your volume disappears.
This is where Target ROAS gets confused with plain ROAS. ROAS is the number you measure after the fact. Target ROAS is the number you feed the algorithm before the campaign runs. Setting the target too high starves the campaign. Setting it too low wastes budget the algorithm didn't need to spend. Most advertisers set it once and never revisit it, which is the actual mistake.
Target ROAS is a promise the algorithm tries to keep, not a promise it guarantees to keep.
How to calculate it
Target ROAS = Target revenue ÷ Ad spend, expressed as a percentage
Worked example. You want every $1 of ad spend to return $4 in revenue. Target ROAS = 400%. You enter 400% into Smart Bidding and the algorithm bids higher on auctions it predicts will convert at or above that value, and lower on ones it predicts won't.
The Australian context
Australian advertisers running Target ROAS on Google Ads often hit a data problem before a strategy problem. Smaller market means fewer conversions per week, so the algorithm has less signal to learn from than an equivalent US or UK campaign. That makes Target ROAS harder to stabilise for niche Australian categories like specialty retail or regional services.
The fix most Australian accounts skip is consolidating campaigns to pool conversion data rather than splitting budget thin across dozens of tightly targeted campaigns. Fewer, better-fed campaigns give Smart Bidding the volume it needs to hit a target reliably. Accurate conversion value tracking matters more here than in bigger markets, because there is less room for noisy data to average out.

Common questions
What's a realistic Target ROAS to set?
There's no universal number. It depends on your gross margin, average order value and how much room you have to pay for acquisition after costs. Start from your break-even ROAS, the point where ad spend just covers margin, and set your target comfortably above that.
How much conversion data do I need before using Target ROAS?
Google recommends at least 15 to 30 conversions in the last 30 days before switching to Target ROAS, though more is better. Below that, the algorithm doesn't have enough signal and performance tends to be volatile rather than predictable.
Why did my Target ROAS campaign stop spending?
If the target is set higher than the auction can realistically deliver, Smart Bidding pulls back rather than chasing an unreachable ratio. It protects the ratio over volume by default. Lowering the target usually restores spend.
Is Target ROAS better than Target CPA?
Neither is universally better. Target ROAS suits businesses with variable order values, since it optimises for revenue per dollar. Target CPA suits businesses where every conversion is worth roughly the same, since it optimises for a flat cost per action.
