A meta description is the short summary of a page that search engines can show under its title in results. It is not a ranking factor, and Google rewrites most of them, yet it is still worth writing carefully, because when yours does display it is the ad copy deciding whether the searcher clicks you or the result below you. Around 150 characters, one clear promise, one reason to click. That is the whole craft.
The short version
- The meta description is the snippet under your title in search results.
- It does not affect rankings. It affects clicks, which are the point.
- Keep it 120 to 155 characters and front-load the key claim.
- Google rewrites about 70% of them, so accuracy is your best defense.
- ~70% of descriptions get rewritten by Google
- 155 characters is the safe desktop length
- 120 characters display reliably on mobile
- 25% of pages ship with no description at all
What the tag looks like
The meta description lives in the head of the page:
<head>
<title>Your Page Title | Brand</title>
<meta name="description" content="Your summary of the page, written like ad copy, under 155 characters.">
</head>Every mainstream platform exposes a field for it. WordPress through Yoast or Rank Math, Shopify under the search engine listing preview, Wix and Squarespace in page-level SEO settings. Finding the field is never the hard part. Writing something a stranger would click is.
How to write one that earns the click
-
Match the intent of the search
A buying query wants price, proof, or an offer. An informational query wants a promise of the answer. Write to what the searcher came for, not what you want to say.
-
Lead with the strongest claim
The first 120 characters are the only part guaranteed to display on mobile. Put the reason to click there, not a warm-up clause.
-
Use the searcher's words
Google bolds terms that match the query, which makes your listing visually louder. This is also what keeps Google from rewriting you: descriptions that speak the query's language get used more often.
-
Be specific, with numbers where honest ones exist
"Includes 4 formulas and real examples" beats "everything you need to know" in every test we have seen. Specifics read as substance.
-
End with the next step
A quiet call to action ("See the pricing", "Read the checklist") finishes the pitch. Skip the shouting.
Four formulas that keep working
- Problem, solution, next step. "Struggling with [problem]? [What the page delivers]. [CTA]."
- What, why, next step. "Learn [what] to [outcome]. Covers [key points]. [CTA]."
- Result, proof, next step. "Get [result] with [service]. [Honest proof point]. [CTA]."
- Question, answer, next step. "What is [topic]? [One-sentence answer]. [What else the page adds]. [CTA]."
One real pair from an ecommerce audit shows the gap. "Shop our bestselling wireless headphones with 40-hour battery life. Free shipping over $50, 30-day returns" gives three concrete reasons to click. "Buy headphones from our store. We sell many types of headphones" could describe ten thousand stores and sells none of them.
The mistakes that cost clicks
- Leaving it blank and letting Google improvise your ad copy.
- Pasting one description across dozens of pages.
- Keyword lists instead of sentences, which read as spam in the SERP.
- Claims the page does not keep. The click you tricked bounces straight back.
- Running long, so the message dies at the truncation ellipsis.
To find the problems at scale, crawl the site with Screaming Frog for missing and duplicate descriptions, then sort Search Console by pages with high impressions and weak click-through rate. Those pages are where a rewritten snippet pays for the hour it takes.
Where the meta description fits
The description works as one half of your search listing, next to the title tag, which is the half that does affect rankings. Together they are the ad you run in every result you earn, and writing them well is part of the same on-page SEO discipline as headings and internal links.
Questions people ask about meta descriptions
Are meta descriptions a ranking factor?
No. Google confirmed back in 2009 that the meta description is not used for rankings. Its job is the click. A snippet that wins more clicks than its position deserves is doing real SEO work, just not through the ranking algorithm.
How long should a meta description be?
Keep it between 120 and 155 characters. Google truncates by pixel width, roughly 155 to 160 characters on desktop and about 120 on mobile, so front-load the message you cannot afford to lose.
Why does Google change my meta description?
Google swaps in its own snippet when it thinks page text matches the query better than your description does. Studies put the rewrite rate around 70%. Accurate descriptions that use the words searchers use get kept more often.
What happens if I leave the meta description empty?
Google generates one by pulling whatever page text seems to match the query. Sometimes that works fine. Often it clips a sentence mid-thought and your listing reads like an accident. Writing your own at least sets the default.
Can I use the same meta description on several pages?
No. Duplicate descriptions waste the chance to sell each page on its own terms and make near-identical listings compete in search results. Every page that matters deserves its own snippet.
