(A) Use maximum and minimum CPC limits or bid estimates
(B) Applying similar rules with different criteria to subsets of your account
(C) Use all five bidding strategies all of the time
(D) Monitor performance at least once per week
The best practices for using automated rules are (1) Use bid estimates provided by Microsoft advertising to set a maximum and minimum CPC bid limit. This helps you to spend less than what is required to get to the top positions of the search engine results. (2) Instead of applying one automated rule across all your campaigns, you can apply similar rules with different criteria to subsets of your accounts. (3) Automated rules help you to monitor performance at least once per week. This helps you to check your ad clicks, conversion, etc. and the budget you have left remaining.
