Meta title is the title of an HTML document visible in a browser tab and often used as the heading of a search result.
Where it helps in practice
A page title helps people and search engines understand the subject and should not become a keyword list or repeated template.
The decision before implementation
Express the primary need, offer and brand in an order suited to intent and limited display space.
