The meta description is a short summary of a page placed in the HTML head. Search engines may use it as the snippet of text below the title in results, which makes it a chance to tell searchers why this page answers their question. Google has said meta descriptions are not a ranking factor, and it often generates its own snippet from page content instead, especially when the searcher's query matches a different part of the page.
What it looks like
The tag sits in the head of the page, once per page.
<meta name="description" content="Compare Quillbrook and Expensify on approval workflows, card controls, accounting sync and pricing for teams of 20 to 500.">When Google uses it, and when it doesn't
Google chooses the snippet for each search. If the meta description summarizes the page well and fits the query, Google may show it. If a passage in the body matches the query better, Google often shows that instead. So the same page can display different snippets for different searches.
This means a meta description works best as an accurate summary of the page's main purpose, not an attempt to cover every possible query.
Writing one that earns the click
Treat it like a short ad for the page, written in plain language.
- Say specifically what the reader will get: the comparison, the steps, the template, the price.
- Use the words a searcher would use, since Google bolds matching terms in snippets.
- Include useful facts where they fit, such as who the product is for or what the guide covers.
- Write a unique description for each important page. For large templated sets, generate them from page data rather than repeating one line.
Length
Snippets are truncated based on available width, which varies by device. There is no length that is correct for ranking, because the description is not used for ranking. Keep the essential message near the start so it survives truncation.
Example
A pricing page description
A made-up analytics product, Graphwick, had the description “Graphwick is the best analytics platform for modern teams.” It says nothing a searcher can use.
The replacement reads: “Graphwick pricing: a free plan for up to 3 users, Team at a flat monthly fee, and custom Enterprise plans with SSO. See what each plan includes.” It answers the question behind a pricing search before the click.
Common mistakes
Leaving it blank on key pages
Google will generate a snippet anyway, but on pages that matter, such as the homepage, pricing and comparisons, a written summary gives you a better chance of a clear, persuasive snippet.
Copying the same description everywhere
A sitewide default description gives Google no useful summary for any page, so it is usually ignored.
Questions
Not directly. Google has said they are not used as a ranking signal. They can affect how many people click your result, which is why they are still worth writing on important pages.
Usually because another passage on the page matches the specific search better, or because the description is vague, duplicated or does not reflect the content.
Some systems may read them as part of a page, but there is no published evidence that they weigh them heavily. AI answers draw mainly on the page's main content.
