Plugin

link

An internal link does not end with .html.

Why: /about.html and /about/ can both serve the same page, which splits its ranking. Clean URLs also read better in results.

The rule is off by default. Google sets no rule for file extensions in URLs, and a host serves about.html at /about.html. Turn it on to keep .html out of your links.

When off: links that end with .html pass.

<!-- ✗ Fails -->
<a href="/about.html">About</a>

<!-- ✓ Passes -->
<a href="/about/">About</a>
