It is never a bad time for an audit, because it is always highly likely to find something that helps to improve. However, you should not particularly choose to start an audit after implementing a recent strategy or update to your account. The best time to conduct an audit is when we begin to detect performance conflicts. It is also a good idea to conduct regular audits if the account is being managed by the same person or team.
Never lose sight of the qualification of who performs the audit, who provides an external and impartial view of the data. Let’s never forget to have an expert on hand.
