When considering user criteria for bids, which option applies to the adjustment of bids?

The option indicating that bids can be modified according to user interactions is correct because it highlights the dynamic nature of programmatic advertising. Advertisers can adjust their bids based on how users engage with their content. For instance, if a particular audience segment shows high engagement or conversion rates, advertisers may choose to increase their bids for that segment to maximize their return on investment. This responsiveness allows more effective allocation of ad spend towards high-performing segments and promotes better campaign performance.

In programmatic advertising, flexibility and adaptability to real-time data are key components. Therefore, making bid adjustments based on user interactions aligns with optimization strategies for achieving targeted campaign goals. By analyzing user behavior, advertisers are better equipped to make informed decisions on how to allocate their budgets effectively in response to user engagement patterns.
