Once you have confirmed an account sync between Google Ads and Google Analytics, and are using auto tagging for URLs, the Search Queries report will become a valuable data mining tool. This report is found within Google Analytics but is specific to the Google CPC traffic generated through Google Ads.
It reveals the actual search queries that resulted in a display of your Google Ads. That data helps define user behavior because it indicates exactly how users are searching for your product or service. Leverage this insight to refine keyword lists, update messaging and create more targeted content.
