Meta Description: How to Write One Google Actually Shows (2026 Guide)

Your meta description is the short paragraph under your page title in Google. It's often the first thing a searcher reads about you, and it decides whether they click your result or the one below it.

Here's the uncomfortable part: Google ignores most meta descriptions. Studies keep finding that Google shows its own snippet instead of the one you wrote for well over half of results. That doesn't make meta descriptions pointless. It means a good one has to be written for how Google actually picks snippets in 2026.

This guide covers what a meta description is, the right length, why Google rewrites them, how to write ones Google keeps, and the mistakes that quietly break them.

What is a meta description?#

A meta description is an HTML tag in a page's <head> that summarizes the page:

<meta name="description" content="Check any page's title, meta description, canonical and robots tags in seconds. Free, no signup.">

Visitors don't see it on the page itself. Search engines may show it as the snippet under your title in search results, and many social and chat apps fall back to it when a page has no Open Graph description.

Does the meta description affect rankings?#

Not directly. Google said back in 2009 that it doesn't use the meta description tag for ranking, and nothing has changed since. Stuffing keywords into it won't move you up.

It matters for a different reason: clicks. Ranking third with a snippet that answers the searcher's question can beat ranking first with a vague one. And when the words someone searched for appear in your description, Google shows them in bold, which makes your result easier to spot.

How long should a meta description be?#

Google's own documentation says there is no length limit. It simply truncates the snippet to fit the screen. In practice:

Pixels matter more than characters, because a "W" is much wider than an "i". The safe approach:

• Aim for 120 to 160 characters.
• Put the important part in the first 120 characters, so mobile users see it even if the end is cut.
• Don't go very short. A 2026 study by Suff Digital of top 10 results found Google ignored 84.6% of descriptions of 70 characters or fewer, compared with 54% of those between 121 and 160 characters.

Why Google rewrites your meta description#

Google treats your meta description as a suggestion. For each search, it decides whether your description or a passage from your page better matches what the person typed. That's why the same page can show different snippets for different searches.

How often does it happen? An Ahrefs study in 2020 found Google rewrote meta descriptions about 63% of the time. The 2026 Suff Digital study found Google ignored the description for 59.7% of top 10 results that had one, and that results ranking first kept theirs most often.

Google is most likely to replace yours when it is:

• Missing, so there's nothing to use
• Too short to describe the page
• Duplicated across many pages, so it doesn't describe this one
• Stuffed with keywords instead of written as a sentence
• Off-topic for the search, for example a homepage description shown for a query about one product

You can't stop rewrites completely, and for long, varied searches that's often fine: Google is picking a passage that answers that exact question. What you can do is make your description the best match for the main search the page targets.

How to write a meta description Google keeps#

1. Write a unique description for every important page. Duplicates are one of the most common reasons Google ignores descriptions. Prioritize the pages that get the most search traffic: homepage, category pages, top products, top articles.

2. Match the search intent. Ask what the person wants when they search the page's main keyword, and say plainly that the page delivers it. "How to fix a 404 error in WordPress, step by step" beats "Welcome to our blog about websites."

3. Include the main keyword naturally. Once, in a sentence. Google bolds it when it matches the search.

4. Lead with the answer or the benefit. The first 120 characters carry the weight. Put the value up front, details after.

5. Add specifics. Numbers, prices, time frames and concrete facts stand out: "Free plan, 5 pages, no credit card" says more than "affordable plans for everyone." Google's documentation specifically suggests descriptions that include useful facts about the page, like a product's price and availability or an article's author and date.

6. Give a reason to click. End with what the reader gets: "See the checklist", "Compare all 12 tools", "Check yours free."

7. Don't promise what the page doesn't deliver. A description that oversells gets the click and loses the visitor, and that bounce doesn't help you.

Examples#

Meta description mistakes that break silently#

Most meta description problems aren't writing problems. They're technical, and nobody notices them because the page looks exactly the same.

• Two description tags. A theme and an SEO plugin each add one. Google may pick either, or neither.
• Blank descriptions after a template change. A redesign or theme update stops outputting the tag on a whole section of the site.
• Every page shows the homepage description. A broken template variable, common after migrations.
• Placeholder text goes live. "Lorem ipsum" or "Default description" shipped to production.
• Descriptions quietly overwritten. A plugin update or bulk SEO edit replaces descriptions you wrote by hand.

How to check your meta descriptions#

1. Check a single page. MyKavo's free Meta Tag Checker shows a page's title, meta description, canonical, robots meta, Open Graph tags and H1 headings, with guidance on what to fix.
2. Search for the page in Google. Search for the page's main keyword or use site:yourdomain.com/page. If the snippet shown isn't yours, Google rewrote it for that search.
3. Use Search Console. In the Performance report, look for pages with plenty of impressions but a low click-through rate. Those are the ones where a better description can earn more clicks.
4. Crawl the whole site. An SEO crawler will list missing, duplicate, too short and too long descriptions across every page.

Watch your meta descriptions for changes#

You can write perfect descriptions today and lose them next month to a theme update, a plugin conflict or a migration. Nothing errors and the page looks the same, so the first sign is usually a drop in clicks weeks later.

MyKavo checks the title and meta description of every page you monitor against an approved baseline, and alerts you when one changes or disappears, with the old and new text side by side.

The bottom line#

Google rewrites most meta descriptions, but it keeps the ones that are specific, between 120 and 160 characters, unique to the page and written for what the searcher wants. Write those for your most important pages, check them regularly, and watch for the silent technical changes that wipe them out.
