How to Write a Meta Description: Length, Examples, and Tips

What is a meta description?

A meta description is an HTML element in a page's head, written as <meta name="description" content="Your summary here">. It is a short summary of the page that search engines may use as the snippet shown below your title in results.

The description is not displayed on the page itself. It exists for search engines, and sometimes for social sharing tools, so it needs to read well on its own, without the surrounding content.

What does Google do with it?

Google's documentation is direct about this. Snippets are primarily created from the page content itself, but Google sometimes uses the meta description element if it might give users a more accurate description. In other words, the description you write is an offer, not a guarantee.

The SEO Starter Guide adds that you have complete control over the words that can be used to generate the snippet, because it comes from your page content. Google may occasionally source snippets from the meta description tag instead. Writing a strong description and a strong first few sentences of page content therefore work together.

These documents describe meta descriptions as a source for snippets. They do not describe them as a ranking input. The value of a good description is in helping people choose your result, which can affect clicks without changing your position.

How long should a meta description be?

Google states that there is no technical length limit for meta descriptions. What it does say is that the snippet is truncated in search results as needed, typically to fit the device width. Because the available width varies between phones and desktops, no single number is guaranteed.

As a practical rule of thumb, many writers aim for about 120 to 160 characters. That is a convention, not a Google requirement. It is long enough to be useful and short enough that the key point usually appears before any truncation. Put the most important information first so that if the end is cut off, the message survives.

Google's guidelines for good descriptions

Google's own guidance, collected from its snippet documentation and starter guide, gives a clear picture of what works.

• Make it short, unique to one particular page, and include the most relevant points of the page. This is Google's own phrasing for a good meta description.
• Use a succinct summary of one or two sentences.
• Summarize the specific page, not the whole site. Identical or similar descriptions on every page are not helpful when individual pages appear in results.
• Include relevant details. Google notes that news or blog posts can list the author, the publication date, or byline information.
• Avoid keyword stuffing. Google says descriptions made of long strings of keywords do not give users a clear idea of the page and are less likely to be displayed as a snippet.

A simple template

If you are staring at a blank field, a three-part structure helps. Start with what the page is or answers, add the most useful specific detail, and finish with what the reader will get or who it is for.

Fill in the parts in order: what this page is or answers, then the key detail that makes it different, then the benefit or audience. Edit until it reads like a sentence a person would say, not a label.

• Part one, the subject: what the page covers or the question it answers.
• Part two, the specific detail: a number, a method, or a distinguishing feature.
• Part three, the payoff: what the reader will learn, get, or be able to do.

Good and bad examples, with real character counts

Examples make the difference clear. The character counts below were measured, so you can see how much room a useful description actually needs.

• Keyword-stuffed, 130 characters: Best cheap running shoes, buy running shoes online, running shoes sale, cheap running shoes free shipping, top running shoes 2026. It is a list of phrases, not a description.
• Generic boilerplate, 133 characters: Welcome to our website. We offer many products and services. Contact us today to learn more about what we do and how we can help you. It could describe any site.
• Specific and useful, 140 characters: Trail running shoes compared: grip, cushioning, weight, and durability tested on gravel, mud, and rock, with picks for beginners and racers.
• Specific for a tool or guide, 122 characters: Hex, RGB, and HSL explained with examples, plus a quick way to convert any color value and check it for readable contrast.
• The description for this article, 150 characters: Learn how to write a meta description that earns clicks: ideal length, what Google actually does with it, good and bad examples, and a quick template.

Writing descriptions for different kinds of pages

The same principles apply across a site, but the emphasis shifts with the page type.

• Blog posts and guides: state the question answered and the main takeaway, and consider the date or author where it adds trust.
• Product pages: name the product type and the details people compare, such as material, size, or compatibility, rather than generic praise.
• Tool pages: say what the tool does with what input, and that it is free or private if that is true.
• Category pages: summarize what is in the collection and how many or what kinds of items to expect.
• Home pages: say who you are and what you do in plain words.

Meta description vs title tag

The title and the description work as a pair. Google's SEO Starter Guide says a good title is unique to the page, clear and concise, and accurately describes the contents of the page. The title identifies the page, and the description gives the reader a reason to click.

Do not repeat the title word for word in the description. Use the title for the topic and the description for the detail. Google's guidance on title links also notes that Google may rewrite titles it finds poor, and the same flexibility applies to snippets, so both should describe the page honestly.

Writing meta descriptions at scale

Writing one description is easy. Keeping hundreds of them unique and accurate is the real challenge, and it is where most sites slip. A template that fills in the same sentence for every page produces exactly the duplicate descriptions Google calls unhelpful.

If you generate descriptions from a template, make sure each one pulls in something specific to the page: its title, its excerpt, a key number, or a distinguishing attribute. Review the generated output, and rewrite by hand the pages that matter most. A sensible order is your highest-traffic pages first, then the pages that already appear in search results but get few clicks.

Google Search Console's performance report shows how often your pages appear in results and how often they are clicked, which helps you spot pages whose snippet is not persuading searchers. Treat a rewrite as an experiment: change one description, wait for fresh data, and compare, instead of rewriting everything at once.

Common meta description mistakes

Most weak descriptions fall into a handful of patterns that are easy to spot once you know them.

• Leaving the field empty and hoping for the best. Google will build a snippet from the page, which may not say what you would have said.
• Using the same description on many pages.
• Stuffing keywords instead of writing a sentence.
• Writing something vague that could describe any page, such as Welcome to our website.
• Making promises the page does not keep, which leads to quick exits.
• Putting the key point at the end, where truncation may cut it off.
• Copying the first paragraph verbatim without checking that it works as a standalone summary.

How to check and control your snippets

To see what you have, view the page source and search for name=description, or look at the description field in your CMS or framework. Review the set of descriptions across your site and fix duplicates and gaps first.

If a page should not show a snippet at all, Google supports a nosnippet meta tag, and the max-snippet setting lets you cap the length. The data-nosnippet attribute can hide specific sections from snippets. These are controls for special cases, not something most pages need.
