Target ROAS in Google Ads: When I Switch and How I Raise It

Last updated: 7 November 2026

Target ROAS (tROAS) is the Google Ads bid strategy that asks for a set amount of conversion value for every dollar you spend. Switched on too early, it starves a campaign of traffic, but switched on at the right moment, it holds spend to a return you can afford. Here is how it works, and the rule I follow before I turn it on and raise it.

Quick Answer: What is target ROAS in Google Ads?

Target ROAS is a Smart Bidding strategy that sets bids to reach an average conversion value per dollar of ad spend, written as a percentage. A 400% target asks for $4 of value for each $1 spent. I switch to it only after Maximize conversion value has held a stable ROAS for about 30 days.

This table compares the two value-based strategies the way I use them.

How does target ROAS bidding work?

The strategy predicts the conversion value each auction is likely to bring and sets your bid to match. Google’s help page says the strategy sets maximum cost per click bids to maximize conversion value at your target. It adjusts in real time using signals such as device, browser, location and time of day.

The target is an average, not a rule for every click. Google defines it as the average conversion value you want for each dollar of ad spend. So a goal of $5 in sales for each $1 spent is a 500% target, as the same page shows.

Google also suggests a starting target once you create the strategy. That suggestion is based on your actual ROAS over the last few weeks, leaving out the most recent days to allow for conversion delays. You can accept it or set your own.

Did Google rename target ROAS in 2026?

Yes, in the interface only. In June 2026, Google changed the label “Maximize conversion value with a Target ROAS” to plain “Target ROAS”, according to the Google Ads Developer Blog. The post says the underlying bidding behavior stays exactly the same, so campaigns keep bidding as before.

What is the difference between Maximize conversion value and target ROAS?

Maximize conversion value chases the most value your budget can buy. Adding a target makes it chase the most value it can get while holding an efficiency goal. Google’s value-based bidding guide frames it the same way: one works within the budget without constraints, and the other adds a ROAS constraint.

The difference shows up in spend. Google says Maximize conversion value tries to fully spend your average daily budget, and can raise spend sharply if you currently spend well under it.

Moving the target pulls in two directions. Google’s guidance says a lower target lets the strategy compete in more auctions for more total value, while a higher one can improve efficiency but may reduce total value. Every step up trades some volume for return.

Which one should you start with?

Start with Maximize conversion value once the account has conversion data with values. It lets the campaign find its natural return without a cap, and that return becomes the evidence for your first target. Starting straight on a target means guessing a number before you have seen what the campaign can do.

When should you switch from Maximize conversion value to target ROAS?

Switch when two things are true: Google’s minimum data is met and your ROAS has been stable. For Search and Shopping, Google asks for at least 15 conversions in the past 30 days, and the conversions need values. Display, Demand Gen and video campaigns have their own thresholds.

My own rule is stricter. Once ROAS has been stable for about 30 days on Maximize conversion value with no target, I switch to a ROAS target. Google’s value-based bidding guide also points to historical 30-day ROAS as the benchmark for a target, so the two line up.

Stable means the month is a fair sample. If a big promotion, a tracking change or a new campaign falls inside that window, the average is misleading. It is better to wait for a cleaner month than to set a target from a distorted one.

What should you check before switching?

Check conversion tracking first. I confirm that GA4, Google Tag Manager and enhanced conversions record each real sale once before I change any bid strategy. My guide to Google Ads conversion tracking covers how. The strategy bids on the values you report, so wrong values mean wrong bids.

Value changes need time too. For Search, Google recommends reporting new or changed conversion values for one to two conversion cycles before adopting the strategy, per its help page. If you have just added values or fixed a tag, the clock starts again.

What if the account has too few conversions?

Then a ROAS target is not the right tool yet. On low-volume accounts that run exact match only, clicks cost more, so I test manual CPC to control what each click costs. Smart Bidding comes later, once there is enough conversion data for it to learn from.

How do I set the first target ROAS?

I set the first target close to the ROAS the campaign actually delivered over that stable month. Google builds its own suggested target from recent actual ROAS. A target near real performance keeps the campaign in the auctions it was already winning.

Then I check it against break-even ROAS, which is 1 divided by the profit margin before ad spend. If a store keeps 40% of each sale after costs, break-even is 2.5, or 250%. A target below that line means the campaign can hit its goal and still lose money. My break even ROAS calculator works this out from your own costs.

If the stable ROAS is already below break-even, raising the target is not the fix. The campaign needs better products in it, cleaner search terms, a better landing page or better margins first. A target cannot create a return the campaign has never shown.

How do I raise target ROAS without losing volume?

After the switch, I push the target up by 15% to 20% and then leave it alone. Changing the target does not put the strategy into Learning, because Google says target updates take effect in the next auction. But Google also says performance can take one to two conversion cycles to settle at a new goal, per its Smart Bidding learning page.

This table shows what that step looks like from three starting targets.

After a step, the two numbers to watch together are conversion value and ROAS. If ROAS rises and value holds, the higher target is working. If value drops sharply, the target has pushed the campaign out of auctions it needs, and Google’s guidance is that a lower target lets the strategy compete in more auctions.

Avoid stacking changes. Google advises against making several ROAS target changes within a single conversion cycle unless there is a real business need. One step, a full cycle to settle, then a decision.

What does the switch look like in an account I run?

The order below is how I take an account from launch to a ROAS target. The timing depends on how fast conversions come in, but the order does not change.

1. Check tracking: GA4, Google Tag Manager and enhanced conversions must record real sales before anything else changes.
2. Launch Search on exact match for roughly the first 15 days, with account-level negatives in phrase and exact match built up front.
3. Add Performance Max once there is conversion data, with guardrails: account-level negatives, irrelevant placements excluded, and blog and other non-selling URLs excluded.
4. Run Maximize conversion value with no target until ROAS has been stable for about 30 days.
5. Set a ROAS target near that stable level, then push the target up by 15% to 20%.
6. Judge every step against break-even ROAS, campaign by campaign.

I never quote a client the ROAS this will reach. A relaunched campaign still in learning has not shown its real return yet, and any number given at that stage would be a guess.

Not every campaign follows the same clock. When a client wants new customers, I leave the live campaigns alone rather than push them back into learning. I test new customer acquisition in a separate campaign that excludes the existing customer list, and that campaign gets its own path to a target.

Why does one target rarely fit a whole account?

Campaigns inside one account can return very different amounts. In the CANA Wine Company account, enabled campaigns ranged from 7.58 to 27.05 ROAS over 120 days, and budgets were split by margin and intent. With a spread like that, one shared target would be too tight for some campaigns and too loose for others.

What changed for target ROAS bidding in 2026?

Two changes matter. The first is the June 2026 rename covered above, which changed labels but not bidding. The second changed behavior: from 17 August 2026, campaigns that are limited by budget and use a target-based strategy deliver more consistently toward the target, according to Google’s help page. Search, Shopping and Performance Max are among the campaign types covered.

Before the update, some budget-limited campaigns beat their targets. Google says those campaigns will now aim closer to the stated target, and that it will not adjust your targets or budgets for you. A target set low as a safety cushion may now be close to the return you actually get.

Google lists the options: keep the target if it reflects your goals, move it to match recent performance, switch to Maximize conversion value to keep volume, or raise the budget with care. For my accounts, the lesson is simple. The target must be the return you want, and it must sit above break-even.

Why is my target ROAS campaign not spending?

The most common cause is a target set above what the campaign has shown it can reach. Google warns that a target set too high may limit the traffic your ads get, per its help page. The fix is to bring the target closer to recent actual ROAS, then step it up again more slowly.

Bid limits are the second cause. Google advises against them for this strategy, because they restrict the AI-based bidding and can stop bids from reaching the target. They also only apply to Search and Shopping portfolio strategies.

The third is bad value data. If conversion values are missing, counted twice or switched off partway through the month, the bid strategy aims at the wrong number. That is why tracking comes first in every account I take on.

Does target ROAS work with Performance Max?

Yes. Google’s Performance Max overview says you can set a ROAS or CPA target alongside your conversion goals. The same logic applies: a target only makes sense once the campaign has a stable return to base it on. My Performance Max guide covers the guardrails I set before launch.

FAQs

What is a good target ROAS?

A good target ROAS sits above your break-even ROAS and close to what the campaign has already shown it can deliver. There is no universal number, because margins differ. A store with a 40% margin breaks even at a ROAS of 250%, so a target under that would lose money even when Google hits it.

Is target ROAS a percentage or a ratio?

Google Ads takes the target as a percentage. A goal of $5 in conversion value for every $1 of ad spend is a 500% target. Reports often show ROAS as a ratio, called conversion value per cost, so multiply that ratio by 100 to compare it with your target.

How many conversions do you need for target ROAS?

For Search and Shopping, Google asks for at least 15 conversions in the past 30 days, with values attached. That is the minimum. I prefer to wait until ROAS has also been stable for about 30 days on Maximize conversion value. A target set from a thin or noisy month starts from the wrong number.

Does changing target ROAS reset the learning period?

No. Google says updates to ROI targets take effect in the next auction and never trigger Learning status. Results still need time, though, because Google says performance can take one to two conversion cycles to settle at a new goal. That is why I make one change and wait, rather than adjust every few days.

Should I use target ROAS or Maximize conversion value?

Use Maximize conversion value while the campaign is building data and you want the most value from the budget. Add a ROAS target when ROAS has been stable and you need spend held to an efficiency level. Since August 2026, budget-limited campaigns also aim closer to their target, so set it at the return you actually want.

What happens if you set target ROAS too high?

The campaign enters fewer auctions. Google warns that a target set too high may limit the traffic your ads get, and its value-based bidding guide says a higher target can reduce total conversion value. If spend and value drop after a change, lower the target toward recent actual ROAS and raise it in smaller steps.

Can you use target ROAS for lead generation?

Yes, if your leads carry values that reflect what they are worth. Google’s value-based bidding guide allows revenue or a proxy such as a lead score, and it asks advertisers to report two or more different values. With one flat value for every lead, the bidding has nothing to choose between.

What should you do before you set a target ROAS?

Work out your break-even ROAS, check that tracking records each sale once, and give Maximize conversion value a stable month before you set a target. Then raise it in one measured step and let it settle.
