Answer the question the page is actually for
On page SEO begins with the content being genuinely the best answer to the search it targets, not a thin piece stuffed with the right words. Keyword stuffing is long dead, and an engine now judges whether a page satisfies the person who clicked. A page that answers the question fully, in plain language, and sends nobody back to search for something it missed is the one that holds its ranking.
Write the direct answer early, in sentences that stand on their own, then give the depth underneath. This also earns you a second prize: a page that answers cleanly is a page an AI engine can quote, which is increasingly where the visibility is. Writing for the reader and writing to be cited turn out to be the same act.
