What you need to know
A title helps search engines and people understand what a page is about. Clear, specific wording is more useful than repeating a keyword or adding a string of generic claims.
How to apply it
Put the main topic naturally near the beginning, add a distinguishing benefit when it is accurate, and keep the title unique across the site. Preview it on a phone-sized result layout.
Common mistake to avoid
Do not promise results the page cannot deliver. Avoid duplicating the same title across articles or stuffing several near-identical keywords.
