Final answer:
The advertiser's ad design is to use drop-down menus for airport departure and arrival locations, rather than showing actual airports, and redirect users to their website when clicked on. This allows for a more controlled user experience and potential analysis of user behavior for personalized recommendations.
Step-by-step explanation:
The advertiser's ad design choice is to use drop-down menus for airport departure and arrival locations, rather than programming the menu to show actual airports. This way, when a user clicks on the ad, they will be redirected to the advertiser's website. This ad design aims to encourage potential customers to visit the advertiser's website to find specific departure and arrival locations for airline tickets.
This approach allows the advertiser to have more control over the user experience on their website and potentially provide personalized recommendations based on the user's preferences. By directing users to their website, the advertiser can also track and analyze user behavior to improve their marketing strategy and understand customer preferences.
