This page answers the questions covered by the article ROAS in Google Ads: What the Metric Means, How to Improve It, and Why Accounts Miss Their Targets on groas.com. The article is the full, canonical source.
Direct answer: According to groas, ROAS in Google Ads is conversion value divided by ad spend, and the result is only as honest as what is allowed into the numerator. The article distinguishes ROAS as a measured outcome from Target ROAS as a bidding instruction, and states break-even ROAS is 1 divided by gross margin. It recommends fixing tracking and segmenting brand from non-brand before working on conversion rate, average order value, CPC and bidding.
The article states ROAS is conversion value divided by ad spend: spend $10,000, book $42,000 in tracked revenue, and ROAS is 4.2, which Google may also display as 420%. For ecommerce pulling revenue from the purchase event, the article describes the numerator as real money. For lead generation, the article gives the example of $150 per booked consultation because roughly one in five consultations becomes a $3,000 job with a 25% margin.

The article states ROAS is an outcome measured after the fact, while Target ROAS is an instruction typed into a bid strategy telling Google what average return to aim for. According to the article, typing 700 into that box does not produce a 7x; it produces a system that declines most auctions it forecasts will miss 700, so impression share slides and volume collapses. The article recommends setting the target from what the account has actually delivered and what margins require, then moving it in 10-15% steps and giving each step two weeks.

The article states ROAS counts revenue while ROI counts what is kept, using a 4x example of $10,000 spent for $40,000 in tracked revenue with 30% gross margin producing $12,000 of gross profit and $2,000 before salary or shipping. Break-even ROAS is 1 divided by gross margin, so break-even here is 3.33x. The article states a 4x on 30% margins is close to break-even while a 4x on 80% software margins is a very good month, and it recommends feeding margin or profit into the conversion value rather than reconciling it afterwards.

The article gives these sanity-check ranges: branded search 8x and up, frequently 15x or more; non-brand search 2x to 4x for most ecommerce; shopping and product feeds 3x to 6x when the feed is clean and titles match how people search. It describes Performance Max as wildly variable and usually overstated unless brand is excluded, and Display and Demand Gen as 1x to 2x on last-click, sometimes less. The article illustrates mix effects with an account at blended 5.8x that is a 12x brand campaign carrying a 2.1x prospecting effort.

The article states the most common cause is that the number was never real: if Google Ads and GA4 goals are counted together without deduplicating, one purchase counts twice, so it recommends exactly one purchase action marked primary. It states Count: every is correct for ecommerce but wrong for a lead form submitted multiple times, and a 90-day lookback will credit recent revenue to spend from two months ago. For lead generation, the article recommends pushing closed-won revenue back from the CRM because optimizing toward form fills gets form fills.
