Why your ROAS is lying to you. It’s time to switch to POAS.
POAS (Profit On Ad Spend) is a metric that is used to measure how profitable your ads are. Unlike ROAS (Return On Ad Spend), POAS focuses on the profit made accounting for costs incurred.
ROAS, while being a standard unit of measurement for ads, has a flaw - not being able to measure scalability. POAS has a powerful metric built into it - a break even point. A 1 POAS means you are breaking even and the money you spend on ads is the amount you are making back. A clear indicator of if your current ads are scalable or not.
With a ROAS based strategy, you are making guesses as to an approximate minimum ROAS on which you base all your decisions. This means, you won’t know if you’re making profit until all the costs are added up. It doesn’t tell you if your ads are scalable or not and it doesn’t tell you if the platform you are using is making you profit independently.
POAS tells you all of this. If you are making a high POAS, it’s time to scale up. Whether you are spending 2k or 20k a month, a POAS metric doesn’t differentiate by revenue. It differentiates by the money you make.
ROAS can lie and might lead you to believe that if you have an equal ROAS on all platforms, you are profitable on all platforms. But has that taken set up costs, creatives costs, COGS and variable costs into consideration?
The short answer is no. The long answer is, if you have a high ROAS but still don’t seem to be making enough money, you want to consider changing your strategy.
