Most digital marketing agencies I talk to spend 3 to 4 hours per client every week doing the same thing. Pull data from Google Analytics. Export from Search Console. Screenshot the Meta Ads dashboard. Open a Google Doc. Paste everything in. Format it. Send it.
Every week. For every client. Manually.
Here is how I automated that entire process using n8n and the Claude API, bringing it down to under 20 minutes with zero manual work.
The workflow in plain English
A scheduled trigger fires every Friday morning
n8n pulls data from Google Analytics 4 via the API
It pulls Search Console data for keyword rankings
It fetches campaign performance from Meta Ads API
All of that raw data gets passed to Claude with a structured prompt
Claude generates a plain English summary of the week, highlights wins, flags anything that needs attention
The output gets formatted into a Google Doc automatically
An email with the report link goes to the client
The whole thing runs while the agency team is asleep.
What Claude is actually doing here
The raw numbers on their own are not useful to a client. A client does not want to read that their CTR dropped from 3.2% to 2.8%. They want to know what that means and what to do about it.
Claude takes the raw data and turns it into a narrative. It compares this week to last week, flags anomalies, and writes in plain English that a non-technical client can understand. The prompt includes the agency's tone of voice guidelines so every report sounds consistent.
The part that surprised me
The biggest time saving was not the report generation itself. It was the back and forth that stopped happening. When clients get a clear narrative report every Friday without chasing anyone for it, the number of "quick update" emails during the week drops significantly. The agency gets their time back twice over.
