How to configure a page title tag
A page title is placed at the top of the HTML page, in the <head> section. The title is written in the <title> tag and it's recommended to give it a powerful description about the page.
The page title must be unique for each individual page so there can be no misunderstanding by the search engine bots when indexing the page. If the page title isn't unique, it can have negative consequences on the position of the page in the search engines results page (SERP).
Large websites often feature their own content management system (CMS) whereby the title of the page doesn't have to be typed directly into HTML, but is managed with the CMS.
