What is a Title Tag?
Learn what a title tag is in HTML, how browsers and crawlers read the title element, and why unique title tags remain a foundational on-page SEO control.
Definition
A title tag is the HTML <title> element in a document head that names the page for browsers, bookmarks, accessibility trees, and search engine result links.
What the title tag does
The title tag names the document. Search engines use it as a strong candidate for the blue link in results. Browsers show it in tabs. Screen readers announce it when a page loads.

Inside the document <head>, as a single <title> element.
