William 的推广活动展示量较低。他应考虑使用哪些策略来扩大触达面？请选择五个答案。

To increase reach for William's campaign with low impressions, several strategies are effective. "Suggested targeting conditions" can uncover new, relevant audience segments. The "LinkedIn Audience Network" extends campaign reach beyond LinkedIn to third-party apps and websites. "Lookalike audiences" (translated as "预测的目标客户") leverage data from existing customers to find new users with similar characteristics. Using the "OR function" in targeting expands the audience by including users who meet any of the specified criteria, rather than all (as with the AND function, which would narrow the audience). Finally, "Audience Expansion" (translated as "广泛投放工具") automatically broadens targeting to similar audiences when the initial audience is too small or restrictive. The "AND function" would reduce reach by requiring users to meet multiple criteria.
