Warning Missing meta description
Why <meta name="description"> matters for search snippets and click-through rate, even though it has no direct ranking effect.
The validator warns when no <meta name="description"> tag is present.
Example
<meta name="description" content="Free HTML validator and tester. Paste HTML or enter a URL to check markup errors, missing attributes, and best-practice issues.">Aim for roughly 50–160 characters — long enough to be a genuine summary, short enough that search engines don't truncate it mid-sentence.
Why it matters
The meta description does not directly affect search ranking — Google has said this explicitly for years. What it does affect is the snippet shown under your result in search listings, and social previews when a link is shared without dedicated Open Graph tags. A well-written description that accurately previews the page content improves click-through rate, which is itself a signal that indirectly correlates with ranking over time.
Frequently asked questions
Does the meta description affect Google rankings?
Not directly — Google does not use it as a ranking factor. It affects the snippet text shown in search results, which influences whether people click through, but has no direct bearing on where the page ranks.
What if I don't set one?
Search engines will auto-generate a snippet by pulling text from the page body, usually whatever text appears near the search query. That's unpredictable and often reads awkwardly out of context — writing your own gives you control over what people see.
