Target ROAS
Bidding & AutomationDefinition
Target ROAS is a Smart Bidding strategy in Google Ads where you tell the system the return on ad spend you want, expressed as a percentage, and it sets bids in every auction to hit that average across the campaign. A target of 400% means you want 4 euros of conversion value for every euro spent. It is a specific product feature, not the metric ROAS itself.
People mix up two things that share the same three letters. ROAS is a result you measure after the fact: revenue divided by ad spend. Target ROAS is a setting you give Google in advance so its bidding algorithm chases that result automatically. When you pick Target ROAS as your bid strategy, you enter a number like 350% and Google predicts the conversion value of each query and bids up or down to keep the campaign average close to your target. It lives in the same family as Maximize Conversion Value, which has no explicit target and simply spends the budget for the most value it can find.
Target ROAS only works when Google can predict value, which means you must send accurate conversion values back into the account, ideally per transaction rather than a single fixed number. Shops feed real order revenue through their conversion tracking; lead-gen accounts approximate value with offline conversion imports or value rules. Without reliable value data the algorithm is guessing, and a clean-looking 600% target produces volatile, untrustworthy results. The strategy also needs volume: as a rule of thumb Google likes to see roughly 15 or more conversions in the last 30 days before a value target behaves predictably.
After you set the strategy, Google uses auction-time signals such as device, location, time of day, query and audience to estimate how much value a given click is likely to generate, then bids accordingly. A query it expects to convert at high value gets a higher bid; a low-value one gets a lower bid or none. The target is an average, not a floor, so individual conversions land above and below it. Setting the number too high too fast is the classic mistake: the system simply stops bidding on anything it cannot confidently win at that return, traffic collapses, and you starve the campaign of the data it needs to learn.
Target ROAS is the lever that ties paid search directly to profitability instead of raw conversion counts. For e-commerce and any account with variable order values it lets you scale spend while protecting margin, because the algorithm chases revenue, not clicks or cheap conversions. Get the target wrong and you either leave volume on the table (target too high) or buy unprofitable sales (target too low). Setting it correctly, anchored to your real break-even ROAS and margin, is one of the most impactful decisions in a Google Ads account.
Example
You sell products at a 50% gross margin, so your break-even ROAS is 200% (you keep 50 cents of every euro of revenue, which is the euro you spent at 200%). To make money you set Target ROAS at 300%: for every euro spent you want 3 euros back, leaving healthy profit after product cost.
A campaign currently runs at an average 450% ROAS. Jumping the target to 800% looks tempting but is too aggressive; Google would slash bids and traffic would dry up. Raising it in steps, to 500%, then 550%, lets the algorithm hold volume while you push return.

Frequently Asked Questions
-
ROAS is the result you measure after spend: conversion value divided by cost. Target ROAS is a Smart Bidding setting where you tell Google in advance the return you want, and the algorithm bids in each auction to hit that average. One is a metric, the other is a strategy that aims for it.
-
Start from your break-even ROAS, which comes from your margin, then add the profit you want on top. Set the target at or slightly above your current achieved ROAS so the algorithm does not have to cut bids hard, then raise it in small steps once it is stable.
-
There is no hard minimum, but value-based bidding behaves far more reliably with roughly 15 or more conversions in the last 30 days and accurate conversion values. With thin data, start on Maximize Conversion Value without a target, then switch once volume and value tracking are solid.
