Synonyms: Web Page Description, Website, Page Description
Much like the title, the page description is a summary (length should be 155-165 characters) of what you will find on that page. Google will sometimes use the page description meta tag as the snippet it shows in search results instead of just page content if they feel it gives a better picture of what to expect from that page. Accurate meta descriptions can help your click-through rate from search engines and social posts.
