Structure Campaigns Properly:
- Segment by product/service groups.
- Separate campaigns by audience type.

javascript
function main() {
  const adIterator = AdsApp.ads()
    .withCondition("Impressions > 100")
    .withCondition("Conversions > 0")
    .forDateRange("LAST_7_DAYS")
    .get();
  
  while (adIterator.hasNext()) {
    const ad = adIterator.next();
    const stats = ad.getStatsFor("LAST_7_DAYS");
    const conversions = stats.getConversions();
    const cost = stats.getCost();
    const estimatedRevenue = conversions * 20; // Adjust based on your conversion value
    const roas = estimatedRevenue / cost;
    if (roas < 2) {
      ad.pause();
      Logger.log("Ad paused due to low ROAS: " + ad.getId());
    }
  }
}

Use Case:

Ideal for gross profit optimization in Google Ads

    const historicalCPC = getHistoricalCPC(campaign);
    const currentCPC = campaign.getStatsFor("LAST_1_DAY").getAverageCpc();
    const threshold = 1.2; // 20% increase threshold
    
    if (currentCPC > historicalCPC * threshold) {
      sendAlert(campaign.getName(), currentCPC, historicalCPC);
    }
  }
}

function getHistoricalCPC(campaign) {
  // Retrieve 7-day average CPC
}

function sendAlert(campaignName, currentCPC, historicalCPC) {
  // Send email/Slack alert
  MailApp.sendEmail(
    "team@startup.com",
