What Are Meta Descriptions? (And How to Write Them)

At 155-characters (or less), meta descriptions are a tiny part of SEO, but they're one of the first things users see. That's because meta descriptions appear in search results, summarizing your page and inviting users to click.

Master the basics of meta descriptions, from what they mean to how to write them, now!

What is a meta description?

A meta description is an HTML tag (<meta name=”description” content=”add your meta description here”>) that summarizes the URL’s content. This description then appears in search results, below a page’s title tag and URL.

In some instances, search engines like Google will rewrite meta descriptions.

What is an example of a meta description?

Below is an example of a meta description in Google’s search results.

Why are meta descriptions important?

Expert Insights From Google logo

“Meta description tags are important because Google might use them as snippets for your pages in Google Search results.”

Google Search Central Source

There are a few reasons meta descriptions are important for SEO:

Keyword relevance

Like other on-page signals, from title tags to headings, meta descriptions help search engines (and users) understand a page’s relevance to a search term, like “dairy-free pumpkin pie recipe.”

When you write meta descriptions that describe your page and use your targeted keywords, you can signal to Google (and other search engines) that your page answers the targeted intent.

Click-through rate (CTR)

Meta descriptions can influence SEO rankings by improving your CTR.

When looking through search results, meta descriptions are the first pieces of text that give users a taste of what’s on your page. Users look at them when deciding whether to click on your page.

The more enticing your meta description, the more likely you are to attract valuable traffic to your site.

Keyword rankings

Meta descriptions aren’t a top ranking factor in SEO.

However, they do play a role, which is why it’s important to optimize your meta descriptions for SEO. We’ll talk about this more in a later section on how to write meta descriptions, but using your target keyword can support higher keyword rankings.

Meta description best practices

Now that you’ve learned the meaning of meta descriptions, let’s explore its best practices:

  • Length: The optimal length for meta descriptions is between 70 – 155 characters.
  • Integration: A meta description should include the page’s target keyword.
  • Format: A meta description should summarize the page and include a call-to-action (CTA).
  • Uniqueness: All meta descriptions on a site should be unique vs. duplicates.

How to write meta descriptions for SEO

Learn how to write meta descriptions for SEO now:

1. Answer the search intent

People turn to search engines to find answers to questions, and they rely on meta descriptions to help them determine if a page holds the answers. 

By answering search intent in your meta description, you can show users that your page fulfills that user’s needs.

For example, look at the difference between a meta description that ignores search intent and one that answers it.

Bad meta description:

Search result for Samwise Gamgee's stew with a meta description that is an introductory excerpt about potatoes

This meta description does nothing to answer user search intent (learn a potato stew recipe), focusing on the chef’s love for potatoes instead. While wholesome, it doesn’t help users looking for a potato stew recipe.

Good meta description:

Search result for Samwise Gamgee's stew with a meta description that promises users a recipe with only five ingredients

Here, the meta description addresses search intent by showing users exactly what they want.

2. Include the targeted keywords

This next meta description best practice is essential to your page’s SEO performance. When writing your meta description, incorporate the page’s target keyword to ensure it appears on the appropriate search results page.

Search engines like Google bold keywords that appear in meta descriptions, capturing users’ attention while scrolling through search results. For example, notice how results stand out when they use the search query’s keywords in their meta descriptions:

The top search results for "best star wars characters" all have meta descriptions that mention the search term

3. Prompt users to click with a CTA

Along with getting users’ attention, your meta description should inspire them to take action. To do this, you can include a CTA in your meta description. 

For example, if you’ve created a list of the best places in your area to buy local produce, you may include a CTA that says, “Visit these local produce vendors in [Location].”

CTAs give users a clear next step to follow and urge them to complete an action that benefits your business. In this case, it’s getting users to visit your website. See how much of a difference a CTA can make in a meta description by reading the following two examples.

Bad meta description:

Search result for the top 10 planets to visit has a descriptive meta description but no CTA

In this example, the meta description is missing a CTA, leaving no clear next step for users.

Good meta description:

Search result for the top 10 planets to visit has a meta description that calls users to explore the best planets to visit on that page

In this example, users are urged to learn more about different vacation destinations.

4. Use a meta preview tool to monitor character count

Finally, when learning how to write great meta descriptions, use a meta preview tool to help you stay within character count. Remember, after 155 characters, Google may cut off part of your meta description, so it’s a good idea to use preview tools to ensure your writing won’t get cut off on Google.

Meta preview tools show you how your meta description will look on Google’s search results once published. For example, WebFX’s Google Preview Tool lets users preview their page’s meta, title tags, and site URLs to get an accurate picture of how it’ll look on Google’s results pages once published.

While going over 155 characters may not seem like a big deal, even just one or two additional characters can affect how your meta description appears on Google.

Bad meta description:

A preview tool shows that a meta description will be cut off, and reveals that it has too many characters

Though this meta description example is so many characters over 155, some words at the end are cut off in the preview.

Good meta description:

A preview tool reveals that a meta description will show in full, and reveals that it is within the character limit

Safely within the 155-character limit, this meta description is displayed in the preview.

5. Generate ideas with AI

If you’re not a writer, you’re not alone.

That’s where AI tools like ChatGPT or Claude can help. You can use these free platforms to generate ideas for meta descriptions. Keep in mind, though, that AI cannot count characters, so most of these meta descriptions will exceed 155 characters.

If you plan on using these meta descriptions, proof them to ensure they:

  • Describe the content
  • Use the targeted keyword
  • Conclude with a CTA

You can also generate meta descriptions programmatically using a Google Sheet.

Why is Google rewriting my meta descriptions?

Google rewrites meta descriptions over 70% of the time, so don’t be alarmed when you see the search engine rewriting yours. According to John Mueller (a member of the Search Relations Team), Google rewrites meta descriptions for a few reasons, including:

  • The meta description is not provided
  • The meta description is spammy
  • The meta description isn’t useful to users
  • The meta description isn’t as relevant to the search intent

You can troubleshoot most of these issues. Some, however, are difficult because users can find your content through a variety of searches. In these instances, Google rewriting your meta description can actually make your description more compelling and relevant.
