Meta description

Long definition

The meta description is never a direct ranking signal. Its job is to earn the click once you're already on the SERP. Google uses it as one candidate among several: the tag you wrote, a passage from the page that matches the query, or a generated summary built from the page content.

Google's own research (published 2017 and restated in 2024) says about 70% of shown snippets are not the declared meta description — the query-matching passage won a coin flip most of the time. That doesn't mean meta descriptions are useless: they dominate for brand queries, navigational queries, and pages where no on-page passage matches the query well.

Optimize for three things:

1. Clarity — if the user reads only this sentence, do they know what the page delivers?
2. Differentiation — what do you offer that the other 9 results don't?
3. Soft CTA — action verb, specific benefit, matching the query intent (how-to, comparison, checklist, etc.).

Character budget fluctuates: Google shows 150-160 on desktop, 130-140 on mobile. Write to 155 and you're safe. The tag is rendered as a <meta> void element — keep it UTF-8 plain text, avoid emojis unless they align with the product voice (they're fragile in the SERP preview).

Common misconceptions

• "Meta descriptions are a ranking factor." They aren't, and Google has said so repeatedly. Good CTR is a user-signal they can observe — indirect lift only.
• "Google always shows what I wrote." Not even close. If the query is informational and your description isn't query-specific, Google picks a passage from the body. Write paragraphs that work as standalone snippets for your target queries.
• "Missing meta description = Google picks randomly." Google picks the best query-matching passage. Often that's better than a weak meta description. Skip it on pages where you can't write something better than the body's opening paragraph.
• "Keyword stuff it for rankings." You'll trigger truncation and get rewritten anyway. Write for humans.
