Meta Title & Meta Description

The meta title and meta description are the page's title and summary snippet, typically shown as the clickable headline and preview text in search results.

Google frequently rewrites meta descriptions (and sometimes titles) in the displayed SERP snippet if it judges a different excerpt better answers the query — writing a good meta description improves the odds Google uses it, but doesn't guarantee it will. Title tags carry more direct ranking weight than meta descriptions, which function more as an organic CTR lever than a ranking signal.
