A meta description is the short summary that appears under your page title in Google's search results. It's a piece of text you write yourself and add to a page. The goal is simple: tell the searcher in a few sentences what they'll find on your page, so they decide to click.
What is a meta description?
The meta description is an HTML element you add to a page's source code. Visitors don't see it on the page itself, but it can appear in the search results. Think of it as the caption under your search result. Your page title grabs attention, and the meta description explains in one or two sentences what the searcher can expect.
It's important to keep three things separate. The meta description is the text you provide. The page content is everything on the page itself: the actual text, headings and images. And the snippet is what Google ultimately shows in the search results. Those three are not the same, and that difference determines how much control you have.
Where do you see a meta description in Google?
You'll find the meta description in the search results, right under the blue title and the green URL of a page. On mobile and desktop it looks slightly different, but the spot is the same: it's the descriptive line that helps the searcher choose between your result and a competitor's.
Meta description versus snippet
A common misconception is that your meta description always appears in Google word for word. That's not true. What you see in the search results is called the snippet, and Google puts that together itself. Sometimes Google uses your meta description unchanged. Often the search engine pulls a piece from your page content that fits the search query better.
So you're submitting a proposal, not a guarantee. The meta description is the text you want to show, the snippet is what Google ultimately makes of it. The better your meta description matches what the page actually offers, the bigger the chance Google uses your version.
Does a meta description affect SEO?
No, a meta description is not a direct ranking factor. Google has confirmed multiple times that the text in this field doesn't directly determine your position in the search results. So you don't climb higher purely because you write a nice meta description, and you don't drop because you leave it empty.
Still, that's not the whole story. The effect is indirect and runs through your click-through rate. A sharp meta description convinces more people to click on your result instead of someone else's. More relevant clicks are a signal that your page matches the search query. That's how the meta description contributes to your SEO, just indirectly, not as a button that pushes your position straight up.
Why is a good meta description still important?
Because a good meta description brings you visitors. Two pages can sit right next to each other at the same position, and still one pulls in more clicks than the other. The difference is often in the text underneath. An inviting, honest description gets more people to click through to your site.
The meta description as a shop window
Think of your meta description as a shop's window display. The search results are the shopping street and everyone walks past. Your page title is the sign above the door, your meta description is what's in the window. If something in there matches what the passer-by is looking for, they step inside. If the window is empty or cluttered, they walk on to the shop next door.
You don't need to exaggerate or make empty promises. You just want to honestly show what's on offer inside, so the right people step in and don't walk straight back out.
How do you write a good meta description?
A good meta description is short, honest and focused on the searcher. You summarize the page, work in your most important keyword naturally, and give a reason to click. Below are the four principles that make the biggest difference.
Summarize the page honestly
Describe what's actually on the page. If your meta description promises something the page doesn't deliver, the visitor will click, but they'll leave again quickly. That helps no one. An honest summary attracts exactly the people you're looking for and keeps them around longer.
Work in your focus keyword naturally
If someone searches for your focus keyword and that word appears in the snippet, Google often bolds it. That stands out and confirms to the searcher that your page is relevant. So work the keyword in, but make it sound natural. A string of loose keywords reads as clutter and puts people off rather than drawing them in.
Write for the searcher, not for the tag
You write the meta description for a human being who's searching, not for the search engine. Picture that person: what do they want to know, and why would your page help them further? A concrete promise or a clear benefit works better than a technically correct but lifeless sentence.
You want to be taken seriously by the search engine; give it mixed signals, and it backs off.

Make every meta description unique
Give every page its own meta description. Copy the same text across dozens of pages, and you give Google mixed signals about what each page is actually about. Duplicate descriptions also make it harder for the searcher to see which page best matches their query. Unique per page is the standard, even if it takes a bit more work.
How long can a meta description be?
Use about 155 characters as a guideline. That's a generic number, not a hard limit, because Google measures in pixels and available space, not characters. Stay around 155 characters, and you have the best chance your whole text stays visible and doesn't get cut off halfway.
Length in characters versus visible space
Desktop has more room than mobile, and wide letters take up more space than narrow ones. So a text with the same number of characters can fit completely on one screen and get cut off with an ellipsis on another. That's why you put the most important part first. If your core message is in the first sentence, it always gets through, even when Google trims the rest.
When doesn't Google show your meta description?
Google regularly overwrites your meta description, and that's not a mistake on your part. The search engine wants to show the searcher the most relevant fragment, and sometimes a piece of your page content fits better than the text you provided. This happens mainly in a few situations.
- Your meta description doesn't match the specific search query well.
- You haven't provided a meta description, so Google picks a fragment itself.
- Your description is too short, too long, or reads like a string of loose keywords.
- The searcher uses a term that appears literally in your page text, but not in your description.
You can't fully force this, and you don't need to. A strong, relevant meta description simply increases the chance Google uses your version. Want to see which pages get which snippet? Then Search Console gives you insight into how your pages appear and perform in the search results.
Where do you add a meta description?
The meta description belongs in the head section of your HTML. In practice you usually don't add it by hand, but through your CMS or an SEO plugin. Below you'll see both methods.
Example in HTML
In the source code, a meta description looks like this. It's a single line within the head of your page:
<head>
<meta name="description" content="Leer wat een meta description is en hoe je er een schrijft die zoekers laat klikken. Praktische tips en voorbeelden.">
</head>Example in a CMS
If you work with WordPress and a plugin like Yoast or Rank Math, you don't need to touch any code. Under every page or post you'll find a field to type in the meta description, often with a meter showing whether your length is right. The plugin automatically places the text in the right spot in your HTML. You usually use that same spot for your title tag, the sign above your meta description.
Common mistakes
Most mistakes with meta descriptions are easy to avoid once you know what to watch for. These are the pitfalls you'll run into most often:
- Pasting the same meta description on multiple pages instead of giving each page its own text.
- Leaving the field completely empty, which hands over all control of the snippet.
- Stacking keywords into a list that reads as spam and puts the searcher off.
- Promising something the page doesn't deliver, which makes visitors leave right away.
- Putting the most important message at the end, so it disappears when Google cuts the text off.
Frequently asked questions about meta descriptions
Is a meta description mandatory?
No, technically it's not mandatory. But if you leave the field empty, Google picks a fragment itself and you no longer have any influence over what the searcher sees.
Does a meta description help my ranking?
Not directly, since it's not a ranking factor. Indirectly, yes: a strong description gets you more clicks, and that's a signal that your page is relevant.
Why does Google show different text than what I entered?
Google picks the fragment that best matches the search query. If a piece of your page content fits better than your description, the search engine shows that piece instead.
How long can a meta description be?
Use about 155 characters as a rule of thumb. Google measures in space, not characters, so always put your most important message first.
Does every page need a unique meta description?
Yes. Duplicate descriptions give Google unclear signals and make it harder for the searcher to recognize the right page. Unique per page is the standard.
