What is a meta description in SEO?
A meta description is a short summary of a web page, written in a <meta name="description"> tag in the page's HTML head. Visitors don't see it on the page itself. Search engines can show it as the snippet, the text under a result's title. Google doesn't use it to rank pages, but it can affect whether people click, which is why every important page should have one.
What the tag looks like
The tag sits inside the <head> of the page, usually right after the title element. A word counter page might use something like this:
<head>
<title>Free Word Counter | Example Tools</title>
<meta name="description" content="Count words, characters, sentences and paragraphs as you type, with a reading-time estimate. Free and runs in your browser.">
</head>The summary goes in the content attribute. Because that attribute is wrapped in double quotes, a double quote inside your text ends it early, so write it as " or use single quotes in the sentence. The HTML standard allows one description per page and says the value must be "appropriate for use in a directory of pages, e.g. in a search engine."
On a CMS such as WordPress, Wix or Blogger, Google's documentation notes that you may set it through a search engine settings page instead of the HTML. If you edit HTML by hand, the Meta Tag Generator builds the description tag along with the title, Open Graph and Twitter Card tags.
Where a meta description appears
The main place is the search results page. Google defines the snippet as "the description or summary part of a search result on Google Search and other properties (for example, Google News)." Your meta description is one possible source for that text; the other is the page itself, and Google says snippets are "primarily created from the page content itself."
Link previews on social apps are a separate system. They are built from Open Graph tags such as og:description, which the Open Graph protocol defines as "a one to two sentence description" of the page. Set those too if you care how a shared link looks; Open Graph tags explained walks through them.
Does a meta description affect rankings?
No. Google said so plainly in a 2009 post about the keywords meta tag: "Even though we sometimes use the description meta tag for the snippets we show, we still don't use the description meta tag in our ranking." Its current snippet documentation talks about the tag only in terms of how results are displayed.
What a description can change is the click. Google's documentation says high-quality descriptions "can go a long way to improving the quality and quantity of your search traffic." Your position stays the same; the aim is for more of the people who see your result to choose it.
Why Google rewrites your description
Google often shows text other than the description you wrote, and its documentation explains why. None of these reasons is a penalty.
| What happened | What Google's documentation says | What to do |
|---|---|---|
| The search was about a detail your description doesn't mention | Snippets "emphasize and preview the page content that best relates to a user's specific search," so Google "might show different snippets for different searches" | Nothing. Describe the page as a whole and let page text answer the narrow searches |
| The page text describes the page better | Google uses the meta description "if it might give users a more accurate description of the page than content taken directly from the page" | Make the description a real summary of the page |
| The description is a list of keywords | Long strings of keywords "are less likely to be displayed as a snippet" | Write one or two plain sentences |
| Every page has the same description | Identical or similar descriptions "aren't helpful when individual pages appear in search results" | Write a page-specific description, starting with your most visited pages |
| The description is too short | Google's examples list the two-word description "Mechanical pencil" as bad | Add the details someone would compare |
Rewrite percentages you see online come from third-party studies; Google doesn't publish a rate. To check your own pages, search for the main query each one targets and see which text Google shows.
Controlling the snippet yourself
Google supports three controls. They limit or remove the snippet; none of them makes Google show your description.
<meta name="robots" content="nosnippet">removes the text snippet. Google may still show a static image thumbnail.<meta name="robots" content="max-snippet:120">caps the snippet at 120 characters. A value of 0 is the same as nosnippet, and -1 lets Google choose the length.- The
data-nosnippetattribute on aspan,divorsectionkeeps that part of the page out of snippets.
Google's robots meta tag documentation adds that the first two also limit how much of your content can be used as a direct input for AI Overviews and AI Mode.
The sales pitch mindset
Think of the meta description as your elevator pitch. Google's own documentation makes the same comparison, saying descriptions "are like a pitch that convince the user that the page is exactly what they're looking for." Don't waste it on fluff like "Welcome to our website."
Meta description examples for different pages
A good meta description for SEO reads like a short answer to "what will I get if I click this?" These made-up examples show what that looks like for four kinds of page, with character counts that include spaces.
| Page type | Example | Chars |
|---|---|---|
| Product page | Waterproof 20-litre hiking backpack with a padded laptop sleeve and two side pockets. Weighs 640 g. Free UK delivery and 60-day returns. | 136 |
| Local business | Family-run Italian restaurant in Bristol city centre. Wood-fired pizza, fresh pasta and a set lunch from £12. Open Tuesday to Sunday, 12 to 10pm. | 145 |
| Blog post | How to repot a snake plant without damaging the roots: when to do it, which pot and soil to use, and what to do in the first two weeks after. | 141 |
| Tool page | Count words, characters, sentences and paragraphs as you type, with a reading-time estimate. Free and runs in your browser. | 123 |
Each one names the thing, then adds the facts a searcher would compare: size and weight, price and opening hours, the questions the article answers. Google's documentation gives the same advice for product pages, where price and other details are "scattered throughout a page" and a description can bring them together.
Compare two descriptions that would likely be ignored:
Welcome to our website. We are the best and offer great products and services for all your needs.(97 characters that could describe any site.)backpack, hiking backpack, waterproof backpack, cheap backpack, best backpack(a keyword list, which Google says is less likely to be shown.)
Where to add a meta description in WordPress and Shopify
WordPress doesn't output a meta description on its own. SEO plugins such as Yoast SEO and Rank Math add a meta description field below the post editor and write the tag for you. Shopify has a "Search engine listing" section on products, collections, pages and blog posts where you can edit the title and description that search engines see. Wix and Blogger also have their own SEO settings, which is what Google's documentation means by a search engine settings page.
Whichever system you use, view the page source afterwards (Ctrl+U in most desktop browsers) and search for name="description". There should be exactly one. Two description tags, often one from the theme and one from a plugin, leave the choice to the search engine.
Meta description vs meta keywords
The two tags are often mentioned together because they sit side by side in old templates. The keywords tag is the one Google's 2009 post was about: Google said it doesn't use the keywords meta tag in web ranking at all. The description tag still has a job, because it can become your snippet in search results. If your template still prints a keywords tag, it does no harm, but there's no reason to spend time on it.
Meta description SEO checklist
- One description tag per page, unique to that page.
- It says what the page gives the reader in the first sentence.
- It includes the words a searcher would use, once, without a keyword list.
- It fits in about 150 characters, with the main point well before the cut.
- Double quotes inside the text are escaped or replaced.
- It matches the page. A description that promises something the page doesn't have is the one Google is most likely to replace.
Writing and checking your first one
Write one or two sentences that say what the page gives the reader, in the words a searcher would use, and add the detail that sets the page apart: a price, a format, a number, or what's free. Paste it into the Character Counter, whose meta description bar measures against about 155 characters, and see how it reads in SERP Preview.

Frequently asked questions
Does a meta description help you rank higher?
No. Google has said it doesn't use the description meta tag in ranking. A clear description can still bring more clicks from the position you already have.
Is the meta description the same as the title tag?
No. The title element usually becomes the clickable headline, which Google calls the title link, and the meta description is a candidate for the text under it. Google can replace either one. How to write title tags covers the title.
What is a meta description example for a home page?
A home page can describe the whole site, which Google's documentation allows for home and other aggregation pages. A made-up plumbing firm might use: Plumbers and heating engineers covering Leeds and Bradford. Boiler repairs, leaks and blocked drains, with 24/7 emergency call-outs. That is 132 characters and names the service, the area and the offer.
What is a meta description limit in Google?
There isn't one. Google cuts the snippet to fit the screen, which works out at roughly 920 pixels on desktop, often quoted as about 155 to 160 characters. The length guide has pixel examples.
Do I need one if Google rewrites it anyway?
Yes. Google can only use your description if it exists. Its documentation suggests that if you can't write one for every page, you should at least cover critical URLs like the home page and popular pages.
