A meta description is a short HTML snippet that summarizes a page's content, and Google often displays it beneath the page title in search results. It lives in the page's <head> and typically runs around 150-160 characters before it gets cut off.
Think of it as the pitch under your headline. When a plumber's page appears in the results for "burst pipe repair Portland," the meta description is the sentence or two that tells the searcher what they will get if they click — "24/7 emergency burst pipe repair in Greater Portland. Fast response, upfront pricing, licensed plumbers."
