Meta description: length, what to write, what to skip
Picture this: your page is sitting in the top 10 for a decent commercial query. Impressions are coming in, the position is stable, the content is fresh. But the clicks aren't there. You open Google Search Console, look at CTR — 0.5%. Position seven should average 3–4%. You're getting seven times less.
You head to the SERP and type the query manually. You find yourself. You see your snippet. And everything clicks into place.
The description is boring. It says the page "is a convenient tool." It doesn't answer the user's question. It doesn't stand out from the nine neighbors around it. The title is fine, the URL is fine — but the description is hollow inside.
Ranking is only half the job. Google said: "You're in the top 10." From there the snippet takes over — three lines of text that decide whether the user clicks or not. And if you didn't invest in those three lines, your position gets stolen by someone below you. Simply because their description is solid.
That's why meta description isn't SEO in the classic sense. It doesn't influence ranking directly. But it influences who in the top 10 gets the click. And a click is your traffic, your conversion, your ROI.
What is a meta description
It's an HTML tag inside <head>:
<meta name="description" content="Page description text..." />
Google reads it and sometimes shows it as the snippet under the title in the SERP. Sometimes it doesn't. Since 2021, Google has officially acknowledged that it rewrites up to 70% of descriptions automatically. Which means in most cases the user sees not what you wrote, but what Google pulled from your page and assembled itself.
That doesn't mean the description is useless. In the remaining 30% of cases Google takes your text — and that's exactly when you control what the user sees. Plus your description is a baseline relevance signal that Google uses when deciding what to pull into the snippet in the first place.
The CTR effect is small but real — 1–5% on a page if the description is written to match the query. On 1,000 impressions a day that's dozens of extra clicks. Over a year of impressions, that's thousands.
Length
Count in characters, not words. Slug, links, spaces — everything in characters. If your CMS counts in words, it's useless, because Google cuts by pixels, and word length varies between Cyrillic and Latin scripts.
— 130–155 characters — optimal for desktop. Google cuts the snippet at roughly 920 pixels, which corresponds to ~155 characters in Cyrillic or ~160 in Latin. — 100–120 characters — what a mobile user sees. On mobile the snippet is shorter, and more than 60% of search sessions now come from phones. So the mobile limit is effectively your main limit. — Less than 100 — Google will almost certainly rewrite it. Too empty to be useful. — More than 160 — gets cut mid-word with an ellipsis at the end. Looks unprofessional, and your CTA at the end will disappear.
Write for desktop (130–155), but the first 100 characters need to carry the main idea — because on mobile that's all they'll see. Like a news headline: the gist first, then the details. If your CTA or a number ends up past 120 characters, it won't show up on a phone.
Don't try to squeeze out the maximum. 145 characters with a clean sentence beats 159 with a forced clause. Simply because those extra 14 characters don't add new information, and a user reads a snippet in two seconds and makes their decision based on the first line.
Cyrillic and Latin take up different pixel counts at the same character count. If you're writing the description in Russian, aim closer to 145. In English, you can stretch to 158. The exact value still varies depending on which font Google is using in any given A/B test.
What to write
Active verb at the start. "Learn," "Compare," "Check," "Download," "See," "Get," "Calculate." A verb in the first position grabs attention — the user reads the snippet in 1–2 seconds, and the first word is critical. Compare for yourself: "Learn how to boost CTR by 30%" versus "Information about how to boost CTR." The first is a promise of action, the second is a recap.
A specific number or figure. "In 60 seconds," "20 checks," "$29/month," "3 steps," "no signup required." Numbers catch the eye, give a sense of concreteness and measurability. "Fast" and "affordable" are empty words. "In 60 seconds" is a promise. After that wording, the user knows what they're signing up for and clicks more willingly.
USP — unique selling proposition. Why this specific page. What you have that the neighbors in the SERP don't. If you write the same thing as everyone else, Google will rewrite you, or the user will click the first link because they all look identical. Differentiate somehow: free, no signup, with examples, for a specific niche. A description aimed at a general audience loses to one aimed at a specific segment.
The target keyword — naturally. Not at the start, not as the opening phrase. Google bolds the match with the query, and the user sees that it's relevant. But don't stuff a keyword for the sake of it — write a sentence the keyword fits into naturally. If the keyword is forced, the eye catches it, and so does the user.
CTA at the end. An arrow "→", a call to "learn more," "get started," "try free," "see demo." A short phrase so the user knows what'll happen after the click. It's a micro-promise: you're promising that the page will give them something, not just tell them about something.
One description — one promise. Don't try to cram your whole sitemap into 150 characters. The user reads the snippet in two seconds and decides: click or not. You have one shot. If you stuff in two topics, the user didn't latch onto either one.
Example of a good description: "Check your site in 60 seconds: 20 SEO factors, prioritized recommendations, free with no signup → start." 132 characters. Verb at the start, two numbers, USP (free, no signup), CTA at the end. Every word pulls weight.
What NOT to write
"Welcome to our website." This is trash filler that carries no information. The user already knows they landed on a site. Tell them what they'll get, not that they showed up.
Duplicating the title. If the title is "Mortgage Calculator 2026: calculate your payment online" and the description is "Mortgage calculator to calculate a payment," you wasted 150 characters. The description should expand the title, not repeat it. Title — what it is. Description — why it's worth clicking.
Keyword stuffing. "SEO audit, SEO check, SEO tool for SEO optimization of your SEO site." Google sees this, downgrades the snippet's relevance, and almost certainly rewrites it. The user sees it and walks past.
Generic words. "Unique," "high-quality," "best," "reliable," "innovative," "cutting-edge." Everyone uses these words, so they mean nothing. Swap them for specifics. Instead of "best SEO tool" — "20 checks in 60 seconds."
Long sentences with "that allows." "A service that allows you to automate the process of analyzing your website with the goal of improving your search rankings." That's 130 wasted characters. Shorten it: "Analyzes a site in a minute. Finds what to fix."
And one more: don't lie. If the description promises "free" but the page is a paid service, the user leaves, bounce rate climbs, Google reads that signal. Two or three weeks of that dynamic and the engine downgrades the page — not because of a bad description, but because of bad behavioral signals. The description has to match what the user sees after the click. That basic honesty cuts bounce and lifts trust.
Separately: don't use quotes inside content — Google sometimes strips fragments with escaped characters. And don't hardcode dates ("in 2026") if the page has a long shelf life — a year from now it'll look stale, and rewriting every description by hand is its own special hell.
Why Google rewrites
Since 2021, Google automatically rewrites up to 70% of descriptions. If yours isn't showing in the SERP, it landed in those 70%.
Reasons:
— The description doesn't answer the query. The user searches "meta description length," but the description talks about something else. Google will pull a paragraph from the page that fits the query better and show that. — Too short or too long. Less than 100 characters and Google thinks you didn't finish. More than 160 and you didn't fit. Either way, grounds to rewrite. — The page catches a lot of different queries. A big topical piece ranks for 20–30 different keywords. One description can't cover all of them. Google assembles the snippet dynamically — tailored to the user's specific query. — The description duplicates the title or meta tags. Google sees duplicates and treats them as noise.
What Google uses instead of your description:
- The first paragraph after the H1 — if it contains keywords from the query.
- The FAQ block — if you have an FAQ with a question similar to the query.
- A quote from the main text — usually from the article body, where the target keyword appears in natural context.
- Structured data — schema.org Article, FAQ, HowTo. Google pulls the description, headline, answer fields.
What to do about it: write a description that catches the main query — then in 30–50% of cases Google will still use it. On top of that, make your H1 and first paragraph work as a snippet too — short, specific, with the keyword. Then even if Google rewrites, it rewrites cleanly. You don't lose control; it just shifts to the level of the page content.
This is, by the way, one of the 30 SEO factors for 2026 — and a fairly underrated one. Everyone fusses over the title and forgets about the description, even though it's the description that breaks CTR most often.
Bottom line
Meta description isn't about ranking. It's about the click from the SERP. Google put you in the top 10 — from there the snippet does the work.
The rules are simple: 130–155 characters on desktop, main idea in the first 100 characters for mobile. Active verb at the start. A number or specific detail. USP. Keyword — naturally, not as the first word. CTA at the end. Don't repeat the title, don't stuff keywords, don't pad.
And remember: even if Google rewrites, it rewrites from your own content. So make your H1 and first paragraph strong enough to carry the snippet role too. That way the page's snapshot in the SERP always works in your favor — regardless of which chunk Google decides to show.
