What is Lazy Loading?
Lazy loading is a technique that delays the loading of non-critical resources at page load time. It can improve initial page load performance, but may impact heatmap data collection.
The Issue with Lazy Loading
When the Heatmap.com script is lazy loaded:
Initial user interactions may be missed
Early page events might not be captured
Scroll depth measurements could be inaccurate
This can lead to incomplete or misleading heatmap data, especially for above-the-fold content.
Recommended Solution
For optimal heatmap accuracy, we strongly recommend:
Load the Heatmap.com script as early as possible in your page's <head> section
Avoid using lazy loading techniques of our script
Implementation Best Practice
Place our script immediately after the opening <head> tag:
<head>
<script>
// Heatmap.com script here
</script>
<!-- Other head elements -->
</head>
This ensures our script loads promptly, capturing all user interactions from the moment the page starts rendering.
