What Is a Meta Description?
A meta description is a short block of text, usually one or two sentences, added to the head of a page to summarize what it covers. It does not directly affect where a page ranks, but it shapes whether a person clicks, and it gives any crawler, including an AI one, a quick, human written summary of the page.
What it looks like
On a normal search result, it is the couple of lines of gray text under the clickable title. It is the pitch for the page: enough to tell someone whether clicking is worth their time.
Why it does not boost rankings but still matters
Google does not use the meta description as a ranking signal, and it will often rewrite it on the results page anyway if it thinks a different snippet answers the query better. But when it is shown as written, it still shapes whether a person clicks, which makes it worth writing well even without a direct ranking effect.
Why it is worth writing carefully
- Give a plain, accurate one to two sentence summary of the page, since a vague or misleading one confuses a crawler as much as a person
- Keep it under about 155 characters so it does not get cut off in search results
- Avoid stuffing it with keywords, it should read like a sentence a person would actually say out loud
A quick check
View source on any important page and look for the meta description tag in the head. If it is missing or generic, writing an honest one line summary is a five minute fix that is easy to skip and easy to overlook.
