The meta title, also known as the title tag or page title, provides Google with an important guideline for the clickable headline of a search result and appears at the very top of the listing. The meta title also appears in the browser tab when the page is open.
The title tag thus serves two purposes: It tells potential visitors at a glance what the page is about. It also serves as an important signal for search engines to categorize the topic.
The meta title should not be confused with the H1 heading. While the two may sound similar, they serve different purposes. The H1 appears on the website, while the meta title—along with the meta description—appears in search results.
As a guideline, around 55 to 60 characters are often used. However, there is no fixed character limit, as Google may truncate title links depending on the device and available width.
