Georgeanne is optimizing her children's books campaign and wants to increase brand awareness. Which of the following is the best strategy to achieve this goal?

Adding new keywords is the best strategy to increase brand awareness because it expands the reach of the campaign to a wider, relevant audience. By targeting more search terms related to children's books, Georgeanne increases the likelihood of her ads being seen by potential customers who may not have been exposed to her brand before. Decreasing bids on low-performing keywords or removing underperforming keywords are optimization strategies aimed at improving efficiency and ROI, not necessarily expanding reach for brand awareness. Adding negative keywords helps refine targeting and reduce wasted spend, but it doesn't actively increase the campaign's exposure.
