An advertiser is targeting audience lists, multiple countries and multiple age demographics in its conversion campaign. The campaign is not meeting conversion goals. The advertiser wants to improve campaign performance but does not want to adjust existing creative assets or audience lists. Which two optimizations can be used to improve performance?

The advertiser is experiencing poor conversion performance and cannot change creative or audience lists. The remaining levers are targeting and budget. Adjusting country targeting and age demographic targeting allows the advertiser to narrow down to higher-performing segments within their existing audience lists. For example, if certain countries or age groups are converting poorly, removing them can improve overall campaign efficiency. Adjusting the daily budget might impact delivery but doesn't inherently improve conversion rates if the targeting is inefficient. Dynamic retargeting is a different strategy, not an optimization of the current campaign's performance issues related to broad targeting. Campaign frequency is generally an optimization for reach and ad fatigue, not directly for conversion rate improvement when the core issue is likely targeting inefficiency.
