Firebase Analytics for Website Not Sending Data in Production: A Troubleshooting Guide

Are you frustrated because your Firebase Analytics for website is not sending any data in production, despite following the integration guide to the letter? You’re not alone! In this article, we’ll walk you through a step-by-step troubleshooting process to help you identify and fix the issue, ensuring your analytics start flowing in no time.

Pre-Troubleshooting Checklist

Before diving into the troubleshooting process, make sure you’ve completed the following:

• Double-checked that you’ve installed the Firebase JavaScript library correctly.
• Verified that you’ve initialized Firebase Analytics with the correct configuration.
• Ensured that you’ve enabled Analytics in the Firebase console for your project.
• Waited for at least 24 hours to allow for data processing and reporting.

Troubleshooting Steps

Step 1: Verify Firebase Configuration

Let’s start by ensuring your Firebase configuration is correct. Open your website’s code and search for the Firebase initialization code. It should look something like this:

import { initializeApp } from 'firebase/app';
import { getAnalytics } from 'firebase/analytics';

const app = initializeApp({
  apiKey: '',
  authDomain: '',
  projectId: '',
});

const analytics = getAnalytics(app);

Verify that the configuration values match the ones in your Firebase console project settings. If you’re using environment variables or a secrets manager, ensure they’re correctly set and accessible.

Step 2: Check Analytics Tag in HTML

The Firebase Analytics tag should be present in your website’s HTML. Inspect the page source to find the following script tag:

<script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','https://www.google-analytics.com/analytics.js','ga');

  ga('create', '', 'auto');
  ga('send', 'pageview');
</script>

Verify that the tracking ID matches the one in your Firebase console project settings. If you’re using a tag manager like Google Tag Manager, ensure the Firebase Analytics tag is correctly configured and fired.

Step 3: Inspect Network Requests

Use your browser’s developer tools to inspect the network requests made by your website. Look for requests to the `collect` endpoint:

https://collect.google-analytics.com/g/collect

If you don’t see any requests, it may indicate a JavaScript error or a misconfigured analytics setup. Check the console for any errors and fix them accordingly.

Step 4: Test Analytics in Debug Mode

Enable debug mode in your Firebase Analytics configuration to test and verify that data is being sent:

import { getAnalytics, logEvent } from 'firebase/analytics';

const analytics = getAnalytics();

// Enable debug mode
analytics.setDebugMode(true);

// Test log event
logEvent(analytics, 'test_event', {
  ' debug_mode_test': true,
});

Open your browser’s console and inspect the network requests. You should see a request to the `collect` endpoint with the test event data. If you don’t see any requests, revisit steps 1-3.

Step 5: Check Firebase Console Project Settings

Log in to your Firebase console and navigate to your project settings. Ensure that:

• Analytics is enabled for your project.
• The correct tracking ID is set.
• The data retention period is set to a value that allows for data collection.

Step 6: Verify Data Collection in Realtime

Navigate to the Realtime section in your Firebase console and verify that data is being collected:

Event	Category	Action
page_view	(not set)	(not set)	(not set)

If you see data flowing in, congratulations! You’ve successfully troubleshooting the issue. If not, let’s move on to the next step.

Step 7: Check for Conflicting Scripts or Libraries

Sometimes, conflicting scripts or libraries can prevent Firebase Analytics from working correctly. Check your website’s code for any other analytics libraries or scripts that might be interfering with Firebase Analytics. Remove or configure them to work alongside Firebase Analytics.

Step 8: Test in Incognito Mode or Another Browser

Test your website in incognito mode or another browser to rule out any browser-specific issues or extensions that might be interfering with Firebase Analytics.

Step 9: Review Firebase Analytics Limits

Verify that you’re not hitting any Firebase Analytics limits, such as:

• Exceeding the maximum number of events per user per day.
• Exceeding the maximum number of properties per event.

Adjust your analytics configuration accordingly to avoid hitting these limits.

Conclusion

Troubleshooting Firebase Analytics for website not sending data in production can be a daunting task. However, by following this step-by-step guide, you should be able to identify and fix the issue. Remember to:

• Double-check your Firebase configuration and analytics tag setup.
• Inspect network requests and debug mode to verify data collection.
• Check Firebase console project settings and data retention period.
• Verify data collection in Realtime and review analytics limits.

By following these steps, you should be able to get your Firebase Analytics up and running, providing you with valuable insights into your website’s performance and user behavior.

If you’re still experiencing issues, don’t hesitate to reach out to Firebase support or seek help from a qualified developer. Happy troubleshooting!
