3 min readApr 25, 2025
When it comes to SEO, every millisecond counts. That’s why web performance is a big deal — especially now that Google uses Core Web Vitals as a ranking factor. One of the easiest, most effective ways to improve your site speed? Minify HTML.
In this post, we’ll walk you through what minifying HTML actually means, why it matters for SEO and performance, and how you can do it correctly. We’ll also include real examples, simple explanations, and clear steps.
What Is HTML Minification?
Minify HTML means removing unnecessary characters from your HTML code without affecting how it works. That includes:
- Whitespace
- Line breaks
- Comments
- Redundant code
Here’s a simple example.
Before Minification:
<!DOCTYPE html>
<html>
<head>
<title>My Website</title>
</head>
<body>
<h1>Welcome</h1>
<!-- This is a comment -->
</body>
</html>After Minification:
<!DOCTYPE html><html><head><title>My Website</title></head><body><h1>Welcome</h1></body></html>
