The Challenge
The marketing team lacked a centralized, automated system to monitor Google Ads campaign performance. Without automation, decision-making was delayed and opportunities for optimization were frequently missed.
Campaign metrics were scattered across multiple reports. Analysts had to manually collect data for spend, clicks, impressions, conversions, CTR, CPA, CPC and ROAS, which was time-consuming and prone to mistakes.
Key Pain Points
-
1
Fragmented Campaign Data
-
2
High Manual Effort Every Month
-
3
Delayed and Inconsistent Reporting
-
4
Limited Visibility for Strategic Decisions
The Automation Solution
An automated Google Ads reporting system that runs monthly on the 1st to collect the previous month’s campaign performance data from Google Ads. The automation processes and formats campaign-level metrics and writes them into Google Sheets with clear month labels. A summary workflow then calculates monthly totals and averages (spend, clicks, conversions, etc.) and writes a consolidated summary for easy tracking and analysis.
Monthly trigger and date calculation
Runs automatically on the 1st of each month at 7 AM (IST). Calculates the previous month’s start and end dates in YYYY-MM-DD format.
Fetch Google Ads data via Google Ads API
Calls the Google Ads API endpoint using a GAQL query to retrieve campaign performance metrics such as cost, impressions, clicks, CTR, conversions, CPA, CPC, ROAS, and revenue for the calculated date range.
Extract and process campaigns
Extracts campaign-level results from the API response and processes each campaign individually to ensure complete and accurate reporting.
Format data
Converts cost values from micros to rupees (cost/1,000,000) and formats all metrics for Google Sheets, including Campaign Name, Spend, Impressions, Reach, Clicks, CTR, Conversions, CPA, CPC, ROAS and Sales.
Insert month label and write campaign data
Inserts a new row to mark the reporting month (e.g., “November 2025”) and writes each campaign’s formatted data into the Google Campaigns sheet using the Google Sheets API.
Calculate and write monthly summary
The workflow reads all campaign data from the Google Sheets file, groups entries by month, and calculates key performance metrics. It computes totals for spend, clicks, conversions and sales, while averaging metrics such as impressions, reach, CTR, CPC, CPA and ROAS. It also derives the conversion rate to provide deeper performance insights. The fully formatted monthly summary is then written to the Google PPC Summary sheet using the Google Sheets API for easy tracking and analysis.
