什么是成本上限竞价？

Cost Cap bidding allows you to set a maximum cost you're willing to pay for each key result (e.g., a lead or conversion). The system then attempts to achieve as many of these results as possible within that cost constraint. This differs from "Maximize results" strategies, which aim to spend your entire budget for the most results, or "Target Cost" strategies, which try to keep your average cost per result close to a specific target without a hard cap. Cost Cap provides more control over the individual cost of each desired action, preventing overspending on less efficient conversions.
