Introduction
The meta description is the short summary that appears beneath your page title in Google search results. It is two or three lines of text, it takes about a minute to write, and it is one of the most neglected parts of on-page SEO — which is strange, because it is the closest thing you have to advertising copy in the search results. Your title gets the searcher to look. Your meta description gets them to click.
This guide covers what a meta description is, how long it should be in 2026, what good ones look like, and the mistakes that waste the space. The length figures were verified against current SEO guides and Google’s own snippet documentation in November 2026. Where sources disagree, the range they agree on is given rather than a single invented number.
What is a meta description?
A meta description is an HTML attribute in the <head> of a page that summarizes what the page is about:
<meta name="description" content="A short, accurate summary of the page in 140 to 160 characters.">It does not appear on the page itself. It appears in search results as the snippet text under the blue title, and it is also used by social platforms and link previews when a page is shared. Its job is simple: tell a searcher, in one or two sentences, what they will get if they click.
Two facts are worth getting straight first. Google does not use the meta description as a ranking factor — confirmed in 2009, and its SEO starter guide still says so. A better description will not move your page up the rankings. Second, Google frequently rewrites it anyway. A 2020 Portent study of 30,000 keywords found Google rewrote 62.78% of meta descriptions on desktop and 71.43% on mobile; more recent estimates from 2026 put the rewrite rate at roughly 60–70%. When Google rewrites your description, it usually pulls a snippet from your page body that it judges more relevant to the searcher’s actual query.
Neither fact makes the description pointless. When Google does show yours, it is your best chance to win the click — and even when it rewrites it, the description still tells Google, and increasingly AI search engines, what your page is about.
How long should a meta description be?
Google sets no hard character limit. Its snippet documentation says there is “no limit on how long a meta description can be, but the snippet is truncated in Google Search results as needed, typically to fit the device width.” The truncation is measured in pixels, not characters — wide letters like W and M take more space than narrow ones like i and l — so there is no single exact number. But current sources agree closely on the practical ranges:
| Device | Pixel cutoff | Character equivalent | Practical target |
|---|---|---|---|
| Desktop | ~920 pixels | ~155–160 characters | 150–160 characters |
| Mobile | ~680 pixels | ~120 characters | Front-load the value in the first 120 characters |
The consensus across 2026 guides is a target of 140–155 characters, with the most important information in the first 120 characters so it survives mobile truncation. Some guides phrase the target as 150–160 characters; the safe play is 140–155 — long enough to make a case, short enough to display in full on desktop, with the core message safe on mobile.
What happens when a description is too long? Google cuts it at the last full word and adds an ellipsis, which makes the listing look unfinished. Too short — under about 70 characters — wastes space that could have persuaded a click. Treat 120 characters as the floor for the part that matters: if the first 120 characters do not explain why someone should click, the rest is doing work the reader may never see. Different surfaces truncate differently, and Google sometimes shows longer or shorter snippets depending on the query, so treat these numbers as a practical guide, not a rule Google enforces.
How to write a good meta description
A good meta description does four things in roughly 150 characters: it says what the page is, it matches the searcher’s intent, it gives a reason to click, and it reads like a sentence a human wrote. The process is short:
- Start with the searcher’s question. What did they type into Google, and what do they want to know? A description that answers that question earns the click; one that describes your company does not. Our guide to search intent explains how to identify what a searcher actually wants.
- Put the keyword and the value first. Include the page’s main keyword naturally near the start — Google bolds matching terms in the snippet, which draws the eye — and follow it immediately with the benefit: what the reader will learn, get, or be able to do.
- Be specific. Numbers, timeframes, and concrete outcomes beat vague promises. “7 methods, ranked by reliability” is more persuasive than “learn all about indexing.”
- Add a call to action. A short prompt — “Learn how,” “See the examples,” “Find out why” — tells the searcher what happens next and nudges them toward the click.
- Write it as a human sentence. No keyword stuffing, no lists of terms separated by pipes, no ALL CAPS. If it would look odd as the first sentence of an email, it will look odd in the search results.
Good vs bad examples
The difference between a good and a bad meta description is easier to see than to describe. Here are pairs on the same topics:
Example 1: a recipe page
- Bad (vague, no benefit): “This page has a chocolate cake recipe. We have lots of recipes on our website. Click here to see them all and browse more.”
- Good (specific, benefit-led): “A moist chocolate cake recipe with a 10-minute prep time and no mixer needed. Step-by-step photos, ingredient swaps, and a frosting that sets in 20 minutes.”
Example 2: a how-to guide
- Bad (keyword-stuffed): “How to check indexing, check if website indexed, Google indexing check, indexing checker tool, check website indexed Google.”
- Good (keyword once, value first): “Learn five ways to check if your website is indexed on Google, from the URL Inspection tool to site: searches — and what each result actually means.”
Notice what the good examples share: the keyword appears once and early, the benefit is concrete, and there is a reason to click now rather than later. The bad ones either say nothing specific, repeat the keyword until the sentence falls apart, or describe the company instead of helping the searcher.
Common mistakes to avoid
Writing the same description for every page. Duplicate meta descriptions are one of the most common on-page SEO errors. When Google sees the same description on fifty pages, it usually ignores all of them and writes its own snippets instead. Every page that matters deserves its own description, written for its own keyword and reader. If you have hundreds of pages, prioritize the ones that get impressions and write those first.
Leaving it blank. If a page has no meta description, Google generates a snippet from the page body. Sometimes that works out fine; often it pulls a navigation label, a cookie notice, or the first sentence of the introduction — which was written to open an article, not to sell a click. Writing the description yourself takes a minute and is almost always better than leaving it to chance.
Keyword stuffing. Repeating the keyword three times in 150 characters does not help rankings — the description is not a ranking factor — and it reads terribly. Use the keyword once, naturally, near the start. If it fits a second time without forcing it, fine; if it does not, leave it out.
Writing for Google instead of the searcher. Descriptions that begin “Welcome to our website” or list a company’s services are written for the company, not the reader. The searcher does not care who you are yet. They care whether your page answers their question. Earn the click first; introduce yourself on the page.
Making a promise the page does not keep. “The complete guide to X” on a page that covers half of X is not persuasive — it is a bounce waiting to happen. A searcher who clicks and immediately leaves signals to Google that the result was not satisfying, which hurts more than a slightly lower click-through rate ever would.
Forgetting mobile. Most searches now happen on phones, where the snippet cuts off around 120 characters. A description whose key benefit sits at character 140 will never be seen by a mobile searcher. Front-load the value: keyword, benefit, and call to action should all fit inside the first 120 characters, with anything after that as a bonus for desktop readers.
Treating it as set-and-forget. Descriptions deserve a review when a page is updated, when its target keyword changes, or when the Search Console Performance report shows a page getting impressions but few clicks. A low click-through rate on a page that ranks well is often a description problem, and rewriting it is one of the cheapest SEO fixes there is. Our guide to writing SEO-friendly blog posts covers the full on-page checklist the description sits inside.
Meta descriptions and AI search
Meta descriptions are taking on a second job. AI search features — Google’s AI Overviews, ChatGPT, Perplexity — build their answers from page content, and a clear, accurate description helps these systems understand what a page is about, even when they generate their own summaries. The same habits apply: accurate, specific, front-loaded with the answer. There is no separate “AI meta description” to write. Our guide to optimizing for AI Overviews and our comparison of SEO, AEO, and GEO explain how these newer surfaces work and what they reward.
A quick checklist
Before you publish a page, run its meta description through this list:
- Between 140 and 155 characters, with the key message inside the first 120
- The main keyword appears once, naturally, near the start
- It says what the page offers and why it is worth clicking
- It is specific — numbers, timeframes, or concrete outcomes, not vague promises
- It has a short call to action
- It is unique to this page, not copied from another
- It reads like a sentence a human would write
- The promise matches what the page actually delivers
FAQ
Why does Google show a different description than the one I wrote?
Google rewrites meta descriptions in roughly 60–70% of cases, usually replacing yours with a snippet from the page body that it judges more relevant to the searcher’s query. This is normal, not an error, and it is not something you can prevent. A good description still matters for the cases where Google keeps it.
Should the meta description match the title tag?
They should complement each other, not repeat each other. The title says what the page is; the description says why it is worth clicking. Repeating the title’s words in the description wastes space that could carry the benefit or the call to action.
How long should a meta description be on mobile?
Google truncates mobile snippets at around 680 pixels, roughly 120 characters. Put the keyword and the core benefit inside the first 120 characters so mobile searchers see them.
The bottom line
A meta description is not a ranking factor, and Google will rewrite it most of the time — and it is still worth writing well. Aim for 140–155 characters, front-load the keyword and the benefit inside the first 120 so mobile searchers see them, be specific about what the reader gets, and add a call to action. Avoid the mistakes that waste the space: duplicates, blanks, keyword stuffing, and promises the page does not keep. Then check the Performance report: a page with impressions and few clicks is telling you its description is not doing its job, and rewriting it is one of the cheapest improvements in SEO.
