How to automate your weekly marketing report with AI
- Level: Intermediate
- A few days to set up
The short answer
Pull the same metrics from each channel into one sheet with matching date ranges, flag changes outside the normal range, and ask a model to draft a short commentary that separates what moved from possible reasons. A marketer checks the numbers and removes unsupported explanations before sharing.

- The marketing problem
- Weekly reporting can become a copy-and-paste exercise. The harder task is identifying a meaningful change, checking whether the data is reliable and deciding what deserves investigation.

- GA4
- Google Ads
- n8n
- Claude API

Step by step
01 Tool
Collect weekly metrics
Pull each channel into one sheet with the same date range and definitions. Automate the pull with connectors or a scheduled workflow, for example in n8n or Zapier.
02 Tool
Flag unusual changes
Compare each metric with its recent average, such as the previous eight weeks, and flag moves outside the usual range with a simple formula rather than asking the model to calculate.
03 AI step
Draft the commentary
Give the model the table, the flags and the change log, and ask it to copy figures rather than calculate new ones.
Prompt to copy
Here is this week’s marketing data with flags, the previous eight weeks and our change log. Write a commentary of under 200 words: what moved and by how much (copy the figures from the table; do not calculate new ones), which flagged changes coincide with an entry in the change log, and three questions worth checking. Label every explanation as a hypothesis unless the change log confirms it. Data: [paste] Change log: [paste]
04 You decide
Check the explanation
Reconcile totals with the source, check each flagged change and delete any causal claim the data does not support.
05 Output
Share the report
Share the reviewed summary, with an owner for each follow-up check.
Where a person decides
A marketer reconciles the numbers with the source and removes any explanation the data does not support before sharing.
What to watch for
- A model can describe a movement without knowing its cause.
- Tracking gaps and reporting delays can look like performance problems.
- An automated report hides errors if nobody reconciles it with the source.
How to tell it is working
- Totals reconcile with each platform.
- Flagged changes are checked, and wrong explanations are logged.
- The team uses the report to decide a next action.
An illustrative example
Input
Illustrative: a weekly report shows fewer conversions immediately after a tracking change.
Output
The decline and the tracking change are flagged together, the explanation is labelled a hypothesis, and measurement is checked before anyone concludes that campaign performance fell.
