Why do paid ads fail to scale efficiently in two-sided platforms?

Paid ads frequently fail to scale efficiently on two-sided platforms primarily due to diminishing marginal returns as the available target audience on one side of the market becomes saturated. Increasing ad spend does not proportionally increase relevant matches if the other side of the network cannot absorb the growth, leading to a supply-demand imbalance. Furthermore, heightened competition among advertisers for limited user attention drives up Customer Acquisition Costs (CAC) significantly without a corresponding increase in conversion quality. This can also degrade the user experience if ads become intrusive, potentially leading to churn and undermining the platform's core value proposition. Ultimately, the effectiveness of ads is inherently tied to the platform's ability to facilitate valuable interactions between both user groups, which advertising alone cannot guarantee beyond a certain point.
