Muriel wants to find new keywords to add to her existing campaigns advertising her crime novels. Which downloadable report should they use to inform their direction?

The search term report is the correct choice because it shows the actual search queries customers used that led to impressions and clicks on Muriel's ads. This direct insight into customer behavior is invaluable for discovering new, relevant keywords to add to her campaigns, as well as identifying irrelevant terms to negative target. The advertised product report focuses on product performance, not search terms. The targeting report details how specific targeting strategies performed, not the search queries themselves. The performance over time report tracks general campaign metrics over a period, and the placement report shows where ads appeared, neither of which directly provides new keyword ideas.
