What change can Louise make if her ad campaign is not reaching its budget?

If Louise's ad campaign is not reaching its budget, utilizing the LinkedIn Audience Network can be an effective solution. The LinkedIn Audience Network expands the reach of ads beyond LinkedIn to partner websites and apps, allowing for greater visibility and increased opportunity for engagement. By extending the campaign's reach in this manner, Louise can attract more impressions and clicks, thereby helping to ensure that her budget is utilized more fully.

Using a more expensive ad format might not necessarily lead to better budget utilization, as it could consume the budget more quickly without guaranteeing improved performance. Reducing audience size can limit the potential reach and engagement of the campaign, possibly leading to a slower budget spent. Setting a lower budget contradicts the goal of trying to reach the full budget; instead, it limits the potential of the campaign to achieve its objectives.
