Warning Missing <title> tag

Why every HTML document needs a <title>, and how it's used by browser tabs, bookmarks, search results, and screen readers.

The validator warns when no <title> element is found (or it's present but empty).

Example

<head>
  <meta charset="UTF-8">
  <title>Free HTML Validator — Pingfloat</title>
</head>

Why it matters

<title> is what shows in the browser tab, in bookmarks, in the browser history, and — critically — as the clickable headline in search engine results pages. It's also the very first thing a screen reader announces when a page loads, giving a non-visual user immediate context for where they landed. A missing or generic title ("Untitled", "Home") wastes all of these.

Frequently asked questions

How long should a title be?

Practically, search engines truncate titles around 50-60 characters in results, so put the important words first. There's no hard spec limit, but anything much longer than that gets cut off where it matters most.

Is one <title> required per page, or can I have several?

Exactly one. The HTML spec allows only a single title element per document, and it must live inside <head>.
