A repeated advertising check can be a good automation candidate when the team understands what it is looking for and what should happen next. A script should make that check more dependable. It should not turn an unclear rule into an unattended campaign decision.
Choose a check with a clear purpose
Start with a task the team already performs and can explain. Reviewing destination availability, looking for unexpected changes or preparing a consistent exception report can be useful starting points. Describe the business problem before choosing the implementation.
Write examples of a genuine issue and a normal situation that should not trigger concern. A campaign with no recent activity may be intentionally paused, seasonal or newly created. Without that context, an automated check can produce a long list of findings that nobody knows how to interpret.
Separate observation from action
A report, an email alert and an automatic campaign change have different consequences. State exactly which of those the proposed script will perform. An initial version that reports its findings gives a person a chance to compare them with the actual account context.
Decide what evidence would justify moving beyond reporting. Some checks are best left as prompts for human review because the right response depends on availability, commercial priorities or a customer journey that the script cannot assess. Automation does not need to control every action to be useful.
Test permissions and side effects
Review the script’s access and intended behaviour before authorising it. Use current official documentation and have someone qualified review unfamiliar code. Understand which services it contacts and what information or changes it may send.
Google Ads preview mode does not apply changes to Google Ads data, but external actions such as sending email through MailApp can still occur. Do not treat a preview as a universal guarantee against side effects. Design the test around everything the script can do, with agreed recipients and a clear way to identify test activity.
Give the alert a useful handover
An alert should explain what was observed, which campaign or destination is affected and what the recipient should verify. Avoid a message that announces failure without enough context to investigate. Choose a recipient who can act or route the issue to the right person.
Agree the urgency and expected response. A broken customer destination may need prompt attention; a periodic planning report may belong in a scheduled review. If every message appears equally urgent, it becomes harder to recognise the one that needs action now.
Maintain the check after launch
Keep an owner, a short description and a stop procedure. Record changes to the rule so a new team member can understand why it behaves as it does. Revisit the check when campaigns, destinations or business priorities change.
Review false alarms and missed issues. A recurring false alarm is a maintenance problem, not a reason to silently ignore the script. Retire checks that no longer serve a useful decision. A small set of understandable checks can be more valuable than a large library running without supervision.
Questions and answers
Which checks make a sensible first automation?
Choose a repetitive check with clear inputs and an understandable exception, such as reviewing destination availability. Start with a report that a person can validate before considering automatic changes.
What should happen after a false alarm?
Record why it fired and whether the rule or response needs adjustment. Repeatedly ignoring a noisy alert can leave the team unprepared when a real issue occurs.
