Why it matters to a buyer
E-E-A-T is not a score a page receives, but it describes the qualities Google's systems try to reward. It matters most for topics that affect health, money or safety, where a thin or anonymous page is a real risk to the reader. For a buyer it is a useful test of any content plan: whether each page will be written or reviewed by someone who has done the thing, whether that person is named, and whether the claims can be checked against sources.
How it is measured or applied
It is applied through visible signals rather than tags. Pages carry a named author with a real biography and credentials, a reviewer where the topic warrants one, dates showing when the content was last checked, and citations to primary sources. First-hand detail, such as photos, process notes and numbers from your own work, shows experience. Off the site, independent reviews and mentions support reputation. There is no direct metric for E-E-A-T, so progress shows up indirectly in rankings for competitive, sensitive queries and in how often other sites cite the content.
