Nikolay is using the bid strategy report to evaluate performance of his Google Search campaign on Target CPA. He wants to understand how his campaign's performance has fluctuated over time with regard to his actual CPA over the past six months. Where can he find this information in the report?

The bid strategy report includes Performance history, which shows how bidding performance metrics change over time. For a campaign using Target CPA, this section is where actual CPA trends can be reviewed across a selected date range such as six months. Google Ads uses this historical view to help evaluate fluctuations in performance rather than just the current status of the strategy. That makes it the correct place to analyze how actual CPA has changed over time.
