The title tag is an HTML tag that helps to understand the topic of a particular webpage in short. The title tag can be seen as a clickable link within search engine results pages (SERPs). Each webpage should have a unique title tag and recommended length for the title is 50 to 60 characters. Google shows a maximum of 60 characters of any web page's title tag in its search results. But recently in February 2021, Gary Illyes confirmed in a Search Central Live video that the Title tag can be longer than the displayable space if it's relevant.
