It finds the right values for these parameters using hyperparameter optimization with the evolutionary optimization package Nevergrad. Alpha controls the shape of the diminishing returns curve (how fast a channel saturates) and Gamma controls the inflection point (when a channel hits saturation). Robyn’s default option, the S-Curve, has 2 parameters: alpha and gamma. Robyn is a n open-source MMM package by Facebook. Source Saturation curves in Facebook’s Robyn Organic channels like SEO can show a convex curve - SEO takes longer, but grows in value over time and that value compounds. It means that you are nowhere near the saturation point, or that there are natural ‘economies of scale’ in the channel, where performance increases as you reach the top. Such curves are the least observed curves in marketing. Convex: A convex curve shows that an increase in investment results in an exponential increase in KPIs. If you find that a channel shows a linear curve, chances are you don’t have enough data, you are not testing over longer time periods, and/or have only experimented at low investment levels that have not reached the saturation point yet. Linear: Linear curves show that advertising has a direct impact on revenue.This curve is the most likely to be seen empirically, and is a good default assumption when building a simple model. Collaborating with the same influencer repeatedly would give similar results because you are not reaching new audiences. Once the high-intent audience has been converted, they won’t buy additional phones. Advertising has a huge impact on sales initially, which diminishes quickly and finally saturates completely.Ī company selling a one-time-buy item like a mobile phone might experience this. Concave: Concave curves have a vertical line at first, followed by a steep drop-off.TV ads are one such example where S-curves can be commonly observed, both because of the mechanics of the channel, and because it usually is a sizeable investment with enough spend to determine the shape of the curve. However, he adds, S-curves are hard to come across empirically because they require “substantially more variance in the data than what the usual datasets include”. S-curve is arguably the most common curve in real-life marketing because we need repeated exposure before giving into temptation, writes Chris Kervinen from Sellforte. S-curve: S-curve has 4 stages: slow growth at first, followed by fast growth, then slow growth and then zero growth.Primarily, there are 4 different types of response curves: That’s one of the things you get out of building a marketing mix model. Sourceįinding out this saturation point for your campaigns is critical to figure out when to pause, continue, or tweak your campaigns to reduce wasted ad spend. Increased investment no longer brings in any new customers. In the below example, you can notice that the curve saturates at $5M. The resultant graph is called a response curve. SourceĭR can be noticed in action if you plot a graph with money spent on the x-axis and the results achieved on the y-axis. After a certain point, also called the saturation point, each dollar you spend has a relatively lower impact. Definition of Diminishing ReturnsĭR says that the output cannot continue to increase at the same rate after a certain point. Creative testing can help improve the situation, as can better optimization to find new pockets of relevant audience, however if you’re going to navigate around saturation you first need to measure it. Ad fatigue sets in for audiences that are repeatedly exposed to your ads, hence they stop paying attentionĭiminishing returns means there’s a ceiling to how much you can spend in a channel before it gets saturated.Expansion requires reaching less relevant or more expensive audiences to reach, harming average performance.The highest-intent audience (the low hanging fruit) has already been converted in the first few runs of the ad.When you continue to increase your advertising spend you see increased customer acquisition cost (CAC) and lower return on investment (ROI).Įssentially, there’s a trade-off between spend and efficiency, which occurs because: Advertising on auction-based platforms like Meta or Google exhibits diminishing returns, meaning as you increase spend, efficiency suffers. You cannot double spend and expect sales to double.
