Helping companies pinpoint optimal ad spend with Curves

Knowing how much ad spend to place against different campaigns can often feel more like guesswork than a science. With the risks of underspending being a missed opportunity for sales, and overspending meaning wasting valuable marketing budget, getting it right is vital for businesses to optimise how they approach setting budgets for advertising.  

Would it be useful to know ahead of time what the optimal amount of money to place against your campaign is? To never spend too little that you miss out on potential customers that could be reached with reasonable cost per acquisition, but never tip into wasting money on expensive customers. 

It may sound like a dream, but Corvidae has developed a unique tool to allow businesses to see exactly what the optimum amount of spending is for your campaign, let’s talk about Curves.  

Spend vs profit analysis With curves 

By plotting daily spend against achieved profit on a graph where each point responds to a specific single day, you can begin to get a picture of how the increases and decreases in ad spend impact the cost it takes to acquire new customers. These graphs can be interesting but often look hard to decipher with the inclusion of anomaly data, and whilst interesting, are rarely transformative in what they can tell us.  

The real magic comes when we fit a parabola through the graph that best fits the data points, as this parabolic curve reveals the underlying relationship between spend and profit. 

The parabolic curve is crucial the power of these graphs, because it helps identify the optimal point of spending.  

This optimal point, which corresponds to the apex or inflection point of the parabola, represents the stage where further spending yields diminishing returns. Initially, acquiring new customers is relatively inexpensive and straightforward, but as the target audience expands, the cost of customer acquisition increases significantly. The curve’s apex marks the exact threshold where additional expenditure no longer translates into profitable returns, signalling that it’s inefficient to continue increasing your marketing spend beyond this point. 

The Power of Curves 

By identifying this inflection point, businesses can adjust their marketing budgets to maximize profitability, ensuring they spend just enough to capture the most cost-effective customers without overshooting and wasting resources.  

In a world where CPAs are on a relentless rise, the power to spend exactly the most optimum amount on your campaign before you achieve diminishing returns allows you the ability to fine-tune your marketing strategies with precision. No more guesswork, no more wasted budget—just data-driven decisions that lead to better outcomes.
