A new coffeehouse downtown would like to run an “afternoon espresso” promotion to increase sales during the afternoon hours on weekdays. Which AdWords feature is most effective for preventing their search ads from appearing at night or on weekends?

  • Managed placements
  • Automatic Bidding
  • Custom ad scheduling
  • Keyword Planner

The correct answer is:

Custom ad scheduling

Explanations: Ad Scheduling (also known as “day parting”) lets you tell Google exactly when you want your ads to run, and more importantly when you do not want them to run. In addition, more advanced users can automatically modify their bids based on time-of-day and day-of-week cycles in campaign performance.
