Before you run advertising campaigns, you need to know exactly what you want. Think about the business goals you want to achieve: increase sales, brand awareness or shopping. Set realistic goals that you can achieve and measure.

With a higher bid, you can speed up your ad exposure. In this case, Facebook will distribute the budget as quickly as possible. Sometimes Facebook will pay the maximum price for you to win the auction faster.
The general rules are simple: an auction is held each time a user displays an ad from a selected target audience. More than one billion such auctions take place daily.
