What Is a Meta Description?

A meta description is the short piece of text Google shows under the blue title of your page in the search results. It is not a ranking factor, but it works like a mini advertisement: together with your title, it decides whether a searcher clicks your result or your competitor’s. In this article you will learn what a meta description actually is, how long it can be and how to write one that earns clicks.

What is a meta description exactly?

A meta description is an HTML tag in the <head> of your page that summarises the content in one or two sentences. In code it looks like this: <meta name="description" content="Your summary here">. Visitors never see that text on the page itself, but they do see it in Google’s search results, in shared links on social media and sometimes in AI answers. Do not confuse the meta description with the outdated meta keywords tag, which Google has ignored for years.

Important to know: Google does not use the meta description to decide where you rank. Google confirms this in its own documentation on snippets. So the text does not influence your position in the search results, but it does influence whether someone clicks through once you are there. And that click behaviour ultimately drives the traffic that does or does not land on your page.

Together with the title tag, the meta description is part of your on-page SEO, the things you control on the page itself to get found more easily. If you want the definition in short, you will also find it in our wiki entry on the meta description.

How long can a meta description be?

Google does not impose an exact maximum, but it cuts the text off as soon as it no longer fits the available box. In practice that means:

Target length: 150 to 160 characters. Any longer and your sentence gets truncated with an ellipsis.
There is less room on mobile than on desktop, so put your most important message up front.
Too short works against you too: a ten-word description wastes valuable advertising space.

Think of it as the back cover of a book: enough to convince, short enough to read at a glance. If you want to see exactly how your snippet will appear in Google before you publish, use our free SERP snippet preview.

How do you write a strong meta description?

A good meta description is sales copy in miniature. These principles help:

Repeat the keyword once, naturally. Google bolds the searched term in the results, which draws attention.
Describe what the reader will find on the page and why that is worth their time.
Give a concrete reason to click: a benefit, a number or a promise.
Make every description unique. Two pages with the same text is a missed opportunity and confusing for Google.
Do not promise anything the page cannot deliver. Misleading copy earns clicks that bounce straight back, and that costs you trust.

How to build that kind of persuasive copy is covered further in SEO copywriting. And if you want to tackle title and description together, our article on the title tag and meta description helps you put it into practice.

Why Google sometimes ignores your meta description

A frustration many companies recognise: you write a neat description and Google shows something completely different. That is correct, and it is normal. Google picks its own snippet from your page whenever it believes that matches the query better. According to Google, this happens in a considerable share of cases.

That does not mean you can skip the tag. For your most important commercial pages, where you want to steer the message yourself, a strong meta description is worth the effort. For hundreds of low-value or archive pages it is a waste of your time: there, Google is welcome to choose for itself.

Does the meta description matter for B2B?

For a B2B company with a long sales cycle, the meta description is not your biggest lever, but it is a free opportunity. Your decision-makers often compare several suppliers in the search results before clicking anywhere. A description that concretely explains what you solve and for whom attracts exactly that qualified click instead of a random one.

Our honest view: do not chase a higher click-through rate blindly. More clicks are only valuable if they lead to enquiries. So align your promise with what the page delivers, and make sure the people who click are genuinely the right audience. If you want to steer this structurally, it belongs in a broader SEO approach where visibility, click behaviour and conversion come together.

Frequently asked questions

Is a meta description a ranking factor? No. Google does not use the meta description to determine your position. It does influence your click-through rate, and that determines how many visitors you get out of a given position.

What happens if I do not fill in a meta description? Google will then pick its own snippet from your page text. That is often arbitrary and rarely as persuasive as copy you deliberately wrote for your most important pages.

How many characters can a meta description have? There is no hard maximum, but around 150 to 160 characters your text usually stays fully visible. Longer gets truncated, shorter wastes space.

Does every page need a unique meta description? For your important pages, yes. Duplicate descriptions are a missed opportunity and make it harder for Google to tell your pages apart.
