Answer :
Answer:
By designing a fresh ad group for the particular sale
By setting time the campaign starts and finishes
Explanation:
Creating an ad group is necessary to make Swee Yin's products appear on search results when users search for related items on Google search engine, this will promote Swee Yin's sale event even though a payment will be made to that effect to run the google ad campaign and setting the start and end date of the campaign is necessary because you will not need your ad still displaying when the sale event is over.
