A title tag is an HTML element that is used to specify the title of a page. It is displayed on search engine result pages as a clickable heading just above the URL and at the top of the browser.

In SEO, the title tag is significant. It is highly recommended to include a unique and relevant title that correctly describes the content of a webpage or a website. Thus, it tells the users and search engines about the nature or type of information contained in your webpage.

An ideal title should be between 50 and 60 characters long. You can also place your primary keywords at the start of your title and put the least important keywords at the end. It is the first thing that a search engine analyzes before ranking your webpage.
