How to Fix Crazy Egg Click Tracker Errors Quickly

By Azon Vault On May 5, 2026

What Is the Crazy Egg Click Tracker?

Crazy Egg is a visual analytics tool that shows where visitors click on your website. The click tracker records mouse movements and generates heatmaps, scroll maps, and confetti reports. When the tracker fails, you lose valuable insight into user behavior.

Common Reasons for Click Tracker Errors

Understanding why the error occurs is the first step to fixing it. Below are the most frequent causes:

Incorrect script placement – The tracking script must be placed just before the closing </body> tag.
Conflicting JavaScript – Other scripts (e.g., jQuery plugins, A/B testing tools) can override the window.CE2 object.
Ad blockers or privacy extensions – These often block Crazy Egg’s domain, resulting in a "track not loaded" error.
Out‑of‑date snippet – Crazy Egg updates its script quarterly; an old snippet may stop working.
HTTPS mismatches – Loading the script over HTTP on an HTTPS site triggers mixed‑content warnings.

Step‑by‑Step Fix Guide

1. Verify the Script Is Correct

Log in to Crazy Egg and copy the latest tracking code.
Paste it immediately before </body> on every page you want to track.
Ensure the snippet includes your unique account_id and site_id.

2. Check for JavaScript Conflicts

Open the browser console (F12) and look for errors that reference CE2 or CrazyEgg. If you see "Uncaught TypeError", try these actions:

Temporarily disable other analytics scripts to isolate the conflict.
Move the Crazy Egg snippet to the very bottom of the page.
Wrap the snippet in a document.addEventListener('DOMContentLoaded', …) block.

3. Test With a Clean Browser Profile

Many users have ad‑blockers that prevent the tracker from loading. Open an incognito window or a browser without extensions and refresh the page. If the heatmap appears, advise users to whitelist your domain.

4. Ensure HTTPS Consistency

Replace any http:// URLs in the script with https://. Mixed content will block the script on secure sites.

5. Clear Cache and Re‑Deploy

After making changes, clear your site’s cache (CDN, WordPress plugins, etc.) and publish the updated pages. Then, go to Crazy Egg → Validate to confirm the tracker loads.

Best Practices to Prevent Future Errors

Schedule a quarterly review of all third‑party scripts.
Use a tag manager (Google Tag Manager) to control script order and versioning.
Monitor the Crazy Egg status page for platform‑wide incidents.
Document the exact snippet location in your team’s code repository.

FAQ

Why do I see a blank heatmap even after fixing the script?: Heatmaps require at least 100 unique clicks to render. Continue collecting data and refresh the report after the threshold is met.
Can I use Crazy Egg on a single‑page application (SPA)?: Yes, but you must re‑initialize the tracker after each virtual page view using window.CE2.track().
What if the error persists after all fixes?: Contact Crazy Egg support with a screenshot of the console log and the exact page URL. Include the snippet version you’re using.
