What Is a Meta Description? [+ SEO & Writing Tips]

Share This Story

A meta description is a webpage summary that can show in search engine results. Meta descriptions should let users know what they’ll find on the page and encourage them to click through (rather than click another result).

Google often (but doesn’t always) displays a page’s meta description below its URL and title.

For example:

Meta description appears below the title link in search results

You should provide a meta description in the section of each page’s code. Within a meta description tag, like so:

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

Here’s an example from WordPress:

Note: Short descriptions can also appear in link previews on social media and other platforms. These are usually taken from the Open Graph tag called the “og:description.” If you don’t supply one, the platform might display your HTML meta description (a type of meta tag) instead.

Meta descriptions (sometimes called SEO meta descriptions) aren’t a direct ranking factor. Google doesn’t take them into account when determining rankings.

But meta descriptions are important for SEO. Because they’re often used to generate snippets that tell searchers about your page. And help you stand apart from competitors on the SERP. 

An effective snippet convinces more people to click your link, increasing your click-through rate (CTR). And can even increase brand awareness

Both can have a positive effect on your SEO.

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

In this example, we searched for “what is SEO.” And Google displayed the meta description written by our team:

Search engine result showing a provided meta description.

But when we searched “what does SEO stand for,” Google replaced the SEO meta description with more relevant text from the page:

Note that Google may bold keywords from the query (or other highly relevant text). This helps users to scan results and find pages that match their needs.

Of course, it’s best to control your site’s snippets as much as possible. So you can protect your branding. 

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

Let’s take a look at best practices for writing meta descriptions:

1. Consider Meta Description Length

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

Meta description checker tools (like To The Web’s) allow you to measure pixel width and preview your snippet. Just bear in mind that the mock-up isn’t 100% reliable.

Technically, there is no length limit on an HTML meta description. But Google truncates snippets based on the amount of space available. 

Like this:

Example of truncated snippet

Truncation could harm your CTR. 

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 out there—155 characters is a common meta description length recommendation. But our testing shows 105 characters is safer. And can help you earn a high CTR.

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 (because words take up more pixels when bolded)

Mobile meta description lengths varying from 99 to 105

Tip: Protect the most important information by placing it at the front of your meta description. This can also help grab readers’ attention.

2. Add the Primary Keyword

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

This won’t affect your SEO directly. But it can encourage users to click. Not least because Google often bolds words that appear in the query. (Or synonyms.)

Let’s say you want to rank for “best trail running shoes.”

In this meta description, the phrase isn’t mentioned specifically. Searchers might not think the page is relevant.

Meta description does not address search intent

This SEO meta description stands out more due to the bolding. And explicitly addresses the searcher’s needs.

3. Cater to Search Intent

Understanding search intent (what the searcher wants to achieve) is key to writing an effective meta description.

When someone searches “buy iphone,” Apple entices users to click through by talking about trade-ins and low monthly payments.

When someone searches “compare iphones,” Apple lets users know they can examine various models.

Note how Google rewrites the meta description for this iPhone 14 specifications page. Because searchers want details—not a vague summary.

Perform search intent analysis before writing meta descriptions. Then assure searchers you have what they need.

4. Include Calls 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—they start with a verb and encourage readers to take action. Direct writing can make meta descriptions more concise, engaging, and persuasive.

Consider this before and after, for 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.

5. Make Every Meta Description Unique

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

That way, you can tell users exactly what each page is about. And maximize your CTR.

Generic, duplicate meta descriptions don’t add value. And they definitely don’t describe what you’ll find on a specific page.

If you don’t have time to write meta descriptions manually, hire SEO writers to craft them for you. Or prioritize writing meta descriptions for the most important pages until you have time to write the rest.
