Quick definition

A meta description is an HTML tag that summarises a page for search engines. Google may use it as the snippet under a result’s title, but it often writes its own snippet from the page text, and the description is not a ranking factor.

Why it matters

The snippet helps a searcher decide whether a result answers their question. A specific description, with what the page offers and why it is different, can earn more clicks from the same position. It is also used by many social and messaging apps when a link is shared without Open Graph tags.

How it works

<meta name="description" content="Compare 2 bedroom apartments for rent in Kilimani: prices, photos, floor plans and agent contacts, updated daily.">

Google chooses the snippet per query. When the description matches what the searcher asked, it is likely to be used; when another passage on the page answers the query better, Google shows that passage instead. Snippet length varies with device and query.

You can restrict snippets with max-snippet or nosnippet robots rules, or exclude parts of a page with data-nosnippet. These also limit how the content can be used in Google’s AI features.

How to check it

  1. Crawl for missing and duplicate descriptions, prioritising templates with many pages.
  2. Compare the snippets Google shows for your main queries with your descriptions.
  3. Write descriptions for pages that earn impressions; low-traffic utility pages can be left to Google.

Common mistakes and misconceptions

  • Myth Keywords in the meta description help rankings.

    In fact Google has said the meta description is not used for ranking. Query words matching the description can appear in bold, which may help clicks.

  • Myth Every page needs a hand-written description.

    In fact Google writes snippets when there is none. Prioritise pages where the snippet affects meaningful traffic.
