Do meta descriptions matter for AI search?

A meta description is the short summary a search engine may display under your title in results. It has never been a ranking factor, and AI answer engines don't synthesize answers from it - they read and quote the page's actual content. So no amount of meta-description tuning will get you cited if the body doesn't contain a clear, retrievable answer.

What the meta description does do is influence whether someone clicks when your page is shown, and it gives a compact, accurate framing of the page. Search engines also frequently rewrite the displayed snippet to better match the query, so your description is a strong default rather than a fixed promise.

Citations come from passages an engine retrieves from your page. That means the highest-leverage 'description' is the answer-first opening sentence in your body content - the self-contained statement that resolves the query. Invest there: make the first thing under your matching heading a quotable, accurate answer.

In short, write the meta description for the human deciding whether to click, and write the page opening for the engine deciding whether to cite. They are two different jobs, and conflating them leads people to over-invest in the one that doesn't move citations.

Keep it useful and honest - it's a click and framing tool, so optimize it for that.
