Climato needs to report on how much they've spent on advertising this month so that they can track spend against budget. Which downloadable report would be most useful to them?

The performance over time report provides a detailed breakdown of advertising metrics, including spend, for a specified date range. This allows Climato to easily track their monthly expenditure against their budget. The placement report shows where ads appeared, not spend. The search term report lists customer search queries that triggered ads, not overall spend. The advertised product report details performance by individual product, which might include spend, but the performance over time report is specifically designed for aggregated spend tracking over a period. The targeting report provides insights into targeting effectiveness, not total spend.
