Explanation:
Google Ads provides advertisers with control over their budget. They choose how much to spend per day, per month and per ad as well as where and how they want to spend. Smart campaign technology allows advertisers to create, oversee, and optimize their campaigns to get benefit from investment. Google Ads lets advertisers set a daily limit on how much of their budget is spent to show their ad and averages daily limit over entire month to restrain their campaign from spending more than expected. Google Ads optimizes advertising strategy and helps in getting the best outgrowth for the business. Google Ads is used in achieving business goals for both big and small advertising budgets.
