If a campaign objective is 'Brand Awareness', which bidding option would likely be most suitable to reach the largest possible audience?

For a 'Brand Awareness' campaign objective, the 'Reach' bidding option is most suitable to reach the largest possible audience. The 'Reach' objective is specifically designed to show your ad to as many unique people as possible within your target audience and budget. Facebook optimizes the delivery of your ads to maximize the number of unique individuals who see your ad, rather than focusing on actions like clicks or conversions. For instance, if your target audience is 1 million people, the 'Reach' bidding option will prioritize showing your ad to as close to 1 million unique individuals as possible within your budget, even if it means a lower frequency of views per person compared to other bidding options.
