Before You Start

Prerequisites 📋

Make sure you have the following ready before diving into the code:

• 📊 A Google Analytics 4 (GA4) property – set up and collecting data for your blog.
• 🆔 Your GA4 Property ID – found under Admin > Property Settings > Property ID in the Google Analytics dashboard. It looks like 123456789.
• 📧 A Gmail account – to receive the alerts and run the script.

Note: The script uses the GA4 Data API, which is free and included with your Google account. No third‑party tools are needed.

Step 1

Create a Google Apps Script Project 📁

1. Go to Google Drive.
2. Click New > More > Google Apps Script.
3. In the script editor, click the + (Plus) icon next to Services on the left sidebar.
4. Find Google Analytics Data API in the list, select it, and click Add.

This adds the required API to your project, allowing the script to read real‑time traffic data.

Pro Tip: Rename your project to something like “Traffic Zero Monitor” by clicking on the title at the top. It helps you find it later.

Step 2

Add the Automation Code ✍️

Copy the entire JavaScript code below and paste it into the Code.gs file in the script editor.

Replace YOUR_PROPERTY_ID_1, YOUR_PROPERTY_ID_2, and your-email@example.com with your actual details. You can monitor a single site by keeping just one object in the sites array.

JavaScript Code (Copy & Paste)

function checkMultipleSites() {
  // Add your blog details here
  const sites = [
    { name: "Your First Blog Name", id: "YOUR_PROPERTY_ID_1" }, 
    { name: "Your Second Blog Name", id: "YOUR_PROPERTY_ID_2" }
  ];
  
  const recipientEmail = "your-email@example.com"; // Your Email Address
  let inactiveSites = []; 

  sites.forEach(function(site) {
    try {
      const report = AnalyticsData.Properties.runRealtimeReport(
        {
          metrics: [{ name: 'activeUsers' }]
        },
        'properties/' + site.id
      );

      let activeUsers = 0;
      if (report.rows && report.rows.length > 0) {
        activeUsers = parseInt(report.rows[0].metricValues[0].value);
      }

      if (activeUsers === 0) {
        inactiveSites.push(site.name);
      }
    } catch (e) {
      Logger.log("Error checking site " + site.name + ": " + e.message);
    }
  });

  if (inactiveSites.length > 0) {
    const siteListText = inactiveSites.join(", "); 
    
    MailApp.sendEmail({
      to: recipientEmail,
      subject: "Alert: No Traffic Detected on Your Blog!",
      body: "Attention: No active users were detected on the following sites in the last 30 minutes:\n\n" + siteListText + "\n\nPlease check your sites immediately."
    });
  }
}

Important: Make sure the Property ID is in the correct format – just the numeric ID, no spaces or other characters. The script uses the real‑time activeUsers metric, which resets roughly every 30 minutes.

Step 3

Authorize the Script 🔐

You must grant permissions before the script can access your analytics data and send emails.

1. Click the Save icon (floppy disk) in the editor.
2. Select checkMultipleSites from the dropdown menu at the top.
3. Click Run.
4. A pop‑up will appear: "Authorization Required." Click Review Permissions.
5. Choose your Google account.
6. Click Advanced > Go to (Untitled project) (unsafe).
7. Click Allow.

The “unsafe” warning appears because the app isn’t verified by Google – that’s normal for scripts you create yourself. Your data remains private.

Step 4

Set Up the Trigger (Automation) ⏱️

Now, let the script run automatically every 30 minutes.

1. On the left sidebar, click the Triggers (clock icon).
2. Click Add Trigger (bottom right).
3. Configure the settings as follows:

• Choose which function to run: checkMultipleSites
• Select event source: Time-driven
• Select type of time based trigger: Minutes timer
• Select minute interval: Every 30 minutes

Click Save. Your traffic monitor is now live!

Pro Tip: To test if it works, temporarily change the interval to “Every 1 minute”. If your site has zero real‑time visitors at that moment, you’ll get an email within a minute!

Wrap‑Up

Conclusion & Final Tips 🎉

You’ve successfully automated your traffic monitoring! Now, whenever your blog traffic hits zero for two consecutive 30‑minute checks, you’ll know instantly. This simple setup saves you from constantly refreshing analytics and helps you react quickly to hosting issues, plugin problems, or unexpected drops.

Here’s a quick recap of what you’ve built:

• Connected Google Apps Script to your GA4 property
• Deployed a script that checks real‑time active users
• Configured automatic email alerts for zero traffic
• Set a time‑driven trigger for 30‑minute checks
