Louis 希望触达 IT 企业的决策者。他应如何定向？请选择所有合适选项。

To reach decision-makers in IT companies, Louis should target by "经验年限" (Years of Experience) and "职位级别" (Job Seniority). Decision-makers typically have significant experience and hold senior positions within their organizations. Targeting by years of experience helps filter for individuals who have spent a considerable amount of time in their industry, indicating a higher likelihood of being in a leadership role. Similarly, targeting by job seniority directly identifies individuals in management, director, or executive-level positions. "年龄" (Age) is generally not an effective or appropriate targeting criterion for identifying decision-makers, as age does not directly correlate with authority or decision-making power within a company.
