What can Google Ads do with audiences created in Google Analytics when the two services are linked?

When Google Ads and Google Analytics are linked, audiences created in Google Analytics can be utilized directly within Google Ads to enhance ad targeting strategies. This means marketers can take specific audience segments defined by behavior, demographics, or engagement levels from Google Analytics and use them to tailor ad campaigns in Google Ads. This targeting capability allows for more precise advertising, improving the efficiency of campaigns by reaching users who are more likely to convert based on their interactions with the website.

The other options do not reflect the functionalities offered by the integration between Google Ads and Google Analytics. Modifying website graphics, adjusting email content, or setting up website cookies do not directly relate to audience targeting within the advertising platform. Instead, the primary value of integrating these two services lies in the ability to leverage detailed audience insights from Analytics to optimize ad performance in Google Ads.
