A hotel chain wants its headlines to dynamically mention the specific city a user is searching for (e.g., "Hotels in Miami"). Which customizer should be used?

Location insertion is the correct customizer because it allows you to dynamically insert the user's geographical location into your ad headlines, descriptions, or paths. This is ideal for a hotel chain wanting to show "Hotels in [City]" based on the user's search or inferred location. Countdown is used for time-sensitive promotions. URL exclusion is not a customizer but a setting to prevent ads from showing on specific URLs. Keyword insertion dynamically inserts a user's search query keyword into the ad, which wouldn't guarantee a city name unless the user specifically searched for a city.
