What Is a Meta Description?

A meta description is an HTML element that provides a short summary of a webpage. It can appear as a snippet below the page's URL and title in Google's search engine results pages (SERPs).

Google automatically generates a snippet for your pages. It bases this snippet on the search query, the content on the page, and the page's meta description. 

Google selects the option it believes best addresses the user's search intent.

This means your meta descriptions should be unique, descriptive, and relevant to the page.

Here is what a meta description can look like on a SERP:

To provide a meta description for a page, add it in the <head> section of the page's code within a meta description tag, like so:

<meta name="description" content="Learn how to develop a tone of voice for your brand and use our template to get started.">

Most content management systems (CMSs) and SEO plugins allow you to add and edit HTML meta descriptions by typing in a designated field.

Here is an example from WordPress:

Are Meta Descriptions Important for SEO?

Yes, meta descriptions are important for SEO, even though they aren’t a direct ranking factor.

Meta descriptions generate snippets that inform searchers about your page and help you stand apart from competitors on the SERP.

An effective snippet convinces more people to click on your link. This increases your click-through rate (CTR) and brand awareness, which are primary goals of most SEO efforts.

Google may also bold keywords from the user's query (or other highly relevant text) found in your meta description. 

This helps users scan results and find pages that match their needs, thus increasing CTR.

Here is an example:

Search engine results page for how to grow milkweed

Controlling your site's snippets as much as possible is important for protecting your branding. 

That’s why you need to write effective meta descriptions.

Should You Set Meta Descriptions on Every Page?

Yes, setting meta descriptions for all your pages is beneficial, but it’s not always necessary.

Google doesn’t always use your meta descriptions because it auto-generates snippets based on user queries or information from the page. 

If Google believes your HTML meta description doesn’t satisfy the searcher's intent, it may generate a different snippet for you.

For example, when we searched for "what does SEO stand for," Google displayed the meta description written by our team:

Search engine result showing a provided meta description.

But when we searched "what is SEO," Google replaced the meta description with more relevant text from the page:

example of google generated meta description

When Google does display your meta description, it’s an opportunity to feature a compelling and clickable snippet. 

By always providing a meta description, you have a better chance of influencing how your page appears in search results.

However, setting a meta description for every page can be time-consuming. If you have limited time, prioritize key landing pages, product pages, and any content that you want to rank.

If you don’t want Google to display a snippet (auto-generated or otherwise), use the "nosnippet" meta tag. This tells Google not to show any text or image preview for that page in the SERPs.

How to Write an SEO Meta Description (Best Practices)

Use these best practices to write effective meta descriptions.

How to write a perfect meta description steps

1. Keep Meta Descriptions to 105 Characters or 680 Pixels in Length

How long should a meta description be?

We recommend a meta description length of 680 pixels or around 105 characters. This length gives you space to write an effective summary while reducing the risk of truncation in the SERP.

Although there is no technical length limit on an HTML meta description, Google truncates snippets based on available space. 

Truncated meta descriptions can hurt your CTR.

For example, consider this meta description:

Example of truncated meta description on SERP

Generally, Google cuts off meta descriptions at around 960 pixels (approximately 152 characters) on desktop and 680 pixels (approximately 105 characters) on mobile.

You might see higher estimations elsewhere—155 characters is a common meta description length recommendation.

The exact number of characters displayed in a snippet depends on various factors, such as:

  • The user's device (e.g., there's more space on desktop than mobile)
  • The width of the characters (e.g., an "m" uses more pixels than an "i")
  • The user's search query
Mobile meta description lengths varying from 99 to 105

2. Include Your Target Keyword

Each meta description should include the page's primary keyword—the main search query you want the page to rank for.

Including your target keyword doesn’t affect your SEO directly, but it can encourage users to click. Google often bolds words that appear in the query or are synonyms, making your meta description more noticeable.

For example, suppose you want to rank for "best trail running shoes." If your meta description doesn’t mention this phrase specifically, searchers might not think the page is relevant.

Meta description does not address search intent

In contrast, a meta description that includes the target keyword stands out more due to the bolding and explicitly addresses the searcher's needs.

3. Give the User What They Want to See

Understanding search intent—the searcher's goal—is key to writing an effective meta description.

When someone searches for "buy iphone," Apple encourages users to click by mentioning trade-ins and low monthly payments.

Apple's "Buy iPhone" page meta description on SERP

When someone searches for "compare iphones," Apple informs users they can compare different models.

For example:

Apple's "Compare iPhone Models" page meta description on SERP

Note how Google rewrites the meta description for this iPhone 14 specifications page because searchers want detailed information, not a vague summary.

Analyze search intent before writing meta descriptions to assure searchers you have what they are looking for.

4. Include a Call to Action

Calls to action (CTAs) tell searchers what they should do next. Use them in your meta descriptions to prompt clicks.

For example:

  • Shop online
  • Learn more
  • Try for free

CTAs are imperative sentences that start with a verb and encourage readers to take action. Direct writing makes meta descriptions more concise, engaging, and persuasive.

Consider this before and after example:

Before: Luggage, travel accessories, and more are available on our website. Complimentary monogramming can be accessed with any purchase.

After: Shop online for premium luggage & travel accessories. Get FREE monogramming with purchase.

Include CTAs in your meta descriptions to get more clicks.

5. Ensure Every Meta Description Is Unique

Write a unique meta description for every page that might appear in Google (i.e., indexable pages). 

Unique meta descriptions tell users exactly what each page is about and can maximize your CTR.

Generic, duplicate meta descriptions do not add value and do not describe what is on a specific page.

For example:

Search engine results page showing duplicate meta descriptions for different pages.

If you don’t have time to write meta descriptions manually, use AI writing tools like ContentShake AI to automate the process. 

Alternatively, prioritize writing meta descriptions for the most important pages until you have time to write the rest.

6. Include Important Product Information

When writing a meta description for a product page, include information about the product's features, benefits, and key statistics. 

This ensures users know they are clicking on a result that matches their intent and expectations.

A good product page meta description should mention:

  • The product name and model number
  • The product price and any discounts or offers
  • The product features and benefits
  • The product availability and shipping options

Including these details makes your meta description more relevant and appealing to potential customers.

For example, here’s a meta description optimized for a product page:

This meta description provides users with a clear overview of the product and its specifications. 

Users searching for this type of shoe are more likely to click on this result than on a generic one without product information.
