What date ranges are used for the performance scoring?
All audits use the date range of 45 days. You can choose to offset the data by a certain number of days, if you wish to.
How are the scores defined?
Scores are given depending on the % of items being checked in the account that need your attention.
For example, if we are auditing to find ad groups with less than "n" keywords, then, the score will be given based on the following logic:
Score of 95 - 5% of the ad groups match the check
Score of 80 - 20% of the ad groups match the check
Score of 60 - 40% of the ad groups match the check
Why does the audit table show – under ACoS for some of my campaigns?
The value of ACoS is shown empty i.e – in cases where your campaign/ad group has some spend value but sales generated by it is 0.
