Meta description
The meta description is a short summary of a page, placed in the <head>:
<meta
name="description"
content="Compare running shoes for flat feet: what support to look for, how to test the fit, and five models our staff wear."
/>
Visitors do not see it on the page itself. Search engines often show it as the snippet below the title in search results, and many social platforms and messaging apps use it as the preview text when a link is shared without Open Graph tags.
Why it matters
Google has said it does not use the meta description as a ranking signal. Its value is in the click: the snippet is your chance to tell searchers what they will find and why this result is the one to open. A clear, specific description can earn more clicks than a vague one, even at the same position.
Search engines do not always use your description. They may build a snippet from the page text when it matches the query better. A good meta description still gives them a strong default, especially for searches on your brand or page title.
What we check
We read the content of <meta name="description">, collapse whitespace, and count its characters:
| Result | Meta description |
|---|---|
| Pass | present, 50 to 160 characters |
| Needs attention | present, but shorter than 50 or longer than 160 characters |
| Fail | missing or empty |
Why these limits:
- Under 50 characters rarely says enough to be useful as a snippet.
- Over 160 characters is likely to be cut off. Search engines truncate snippets by pixel width and the device used, so 160 is a rule of thumb rather than a hard limit.
How to write a good description
Summarize the page, specifically. Say what this page offers that others do not: the topic, the format (guide, comparison, product, tool) and any concrete detail that helps a searcher decide.
Write for people. Use a full sentence or two in plain language. Avoid lists of keywords; search engines tend to ignore descriptions that look like keyword stuffing.
Put the important part first. If the snippet is shortened, the beginning is what remains.
Make each description unique. Repeating the same description on many pages gives search engines no useful information and is likely to be ignored. If you cannot write one for every page, it is better to write good ones for the most important pages and generate the rest from page data than to copy one text everywhere.
Match the content. A description that promises something the page does not deliver earns a click and then a quick return to the search results.
How to fix common cases
Missing description. Add the tag to the page template and fill it from a dedicated field in your CMS. Most CMSs and SEO plugins have a “meta description” or “SEO description” field per page.
The same description everywhere. A hard-coded site tagline in the template. Change the template to use the page’s own description, and fall back to an automatically generated one (for example, the first sentence of the content) only when the field is empty.
Too long. Cut filler and keep the key information in the first part. You do not need to fill all 160 characters.
Generated from product data. For large catalogs, build descriptions from structured fields (product name, key feature, price range, availability) so each one is unique and accurate.
Make sure the tag is in the server-rendered HTML. A description added later by JavaScript may not be picked up by every crawler or link preview.
