The meta description is the HTML tag that summarizes the page in one or two sentences and that Google may show below the title in search results. It isn’t what ranks the page higher, but it’s what convinces people to click your link and not a competitor’s. To write a good one, say what the page offers, who it’s for and what the next step is, in about 140 to 160 characters.
Almost every site has one, and almost all of them are bad or blank. You can fix yours in minutes, because the text is yours.
What a meta description is
The meta description, also called the meta tag description, is a line in the page’s code, inside the head, that describes its content. Visitors don’t see this line on the page. The search engine does, and sometimes the searcher too, when Google uses it as a snippet.
The snippet is the piece of text that appears under the result title. Google’s page on snippets defines it this way, and explains that the search engine builds the snippet mainly from the page’s own content. In some cases it prefers the summary you wrote, when it describes the page better than the text on it.
In practice, it works as the storefront of your result. The title says the topic, the URL says where it lives, and the summary answers whether it’s worth the click.
Does the meta description change your ranking?
Not the way Google treats it. The documentation describes the tag as a short summary that informs and interests searchers, a kind of pitch to convince people that the page is the one they’re looking for. It doesn’t present it as a ranking factor.
The effect is indirect and shows up in the click. Google itself says good-quality descriptions can improve the quality and quantity of traffic coming from search. Two pages in the same position, one with a clear summary and the other with generic text or a summary cut off mid-sentence, don’t get the same number of visits.
That’s why it belongs in on-page SEO as a way to improve how the result converts, not as a ranking trick. Anyone who promises to move you up with it alone is selling something it doesn’t do.
How long a meta description should be
Google says there’s no length limit for this summary, but that the snippet is truncated when needed, usually to fit the device width. So there’s no official character count that guarantees the whole text is shown.
Market practice is to write between 140 and 160 characters. It’s a convention, not a Google rule. In that range, most summaries show in full on desktop and mobile, with room to say something useful.
Two practical consequences. First, put the most important part in the first 100 characters, because a cut, when it happens, hits the end. Second, don’t pad the sentence just to get close to 160. A 130-character summary that says everything beats a 160-character one full of filler.
If you want to control the length of the displayed text, Google offers the max-snippet tag, which sets a maximum number of characters for the page’s snippet. It’s a technical feature, and WordPress users usually handle it with an SEO plugin.
How to write a meta description in 6 steps
To write a summary that convinces, the path is the same for any business.
- Start with what the page offers. “Dentist in Campinas for whitening and implants” says more than “Welcome to our website.”
- Use the keyword the person typed. Searchers look in the summary for the term they typed.
- Include a concrete detail. City, type of service, hours, audience, format. A real number is worth more than an adjective.
- End with a next step. “See the menu,” “Request a quote,” “Book on WhatsApp.”
- Write one per page. Google’s documentation asks for a unique description for each page, with site-level text only on the home page and listing pages.
- Reread it as the searcher. If you were that person, would you click?
Two things to avoid. Lists of keywords separated by commas, which Google cites as a bad example and which are less likely to be displayed. And promises the page doesn’t keep, which get the click and then an immediate bounce.
8 before and after meta description examples
The table shows eight different businesses. The data is sample data, and you swap in your own. Notice that the “after” always says what it is, where, who it’s for and what to do next.
| Business | Before | After |
|---|---|---|
| Physical therapy clinic | Physical therapy clinic. Pilates, RPG, rehab, orthopedics. Contact us. | Orthopedic physical therapy and clinical Pilates in Curitiba, with an individual assessment before treatment. Book on WhatsApp. |
| Accounting | We are an accounting firm with years of experience and quality. | Accounting for MEI sole proprietors and small businesses in Goiânia, including CNPJ registration, taxes and payroll. Request a quote on our site. |
| Online clothing store | Women’s clothing store. Dresses, blouses, pants, skirts. Buy now. | Women’s dresses, blouses and pants from S to XL, with easy exchanges and shipping across Brazil. Shop the new collection. |
| Restaurant | Welcome to our restaurant. Come check it out. | Home-style restaurant in Santos, with a daily lunch special and group reservations. See the menu and address. |
| Dentist | Full-service dental clinic with qualified professionals. | Dentist in Campinas for whitening, implants and braces. See the treatments and the clinic’s address. |

What changed in all of them: the city appeared, the service became specific and the ending became an action. No “after” uses “the best,” “complete” or “quality,” words any competitor would write too.
In Brazil, regulated fields such as health and law have professional council advertising rules, and the summary in the search result can also count as advertising. Write information, with no promise of results and no comparisons.
Why Google rewrites your description
Google rewrites it because the snippet is built for each search, not fixed per page. The documentation says snippets are created mainly from page content and that the search engine may show different excerpts for different queries.
This explains the most common complaint: “I wrote one thing and Google showed another.” Three situations usually cause it.
- The search is about a detail your description doesn’t cover. Google pulls the part of the page that best answers that question.
- The description is empty, duplicated or generic. If every page has the same text, it describes none of them.
- It doesn’t match the content. If the summary promises what the page doesn’t deliver, the page text wins.
The right response is not to fight Google. It’s to write descriptions that describe the whole page and answer its main question well. When your text is the best answer, it gets used. When it isn’t, the swapped excerpt usually helps the visitor more. If a swapped excerpt always shows up for the same search, it’s a sign your page or your summary leaves that information out.
Where to edit the meta description
In most cases you edit it in the dashboard of the system that builds your site, without touching code. Google’s documentation notes that on platforms like WordPress, Wix and Blogger, there is a search settings page or an equivalent mechanism for this.
- WordPress with Yoast SEO. The field is in the plugin box, below the page or post editor, next to the preview of how the result appears. The guide to Yoast SEO covers the whole plugin.
- WordPress with Rank Math. It’s in the plugin panel, in the page’s snippet editor. The article on Rank Math details the setup.
- Shopify. Each page, product and collection has a search engine listing area, where you edit the title and description.
- Wix. The description is in each page’s SEO settings, and there’s a site-wide default you can override page by page.
The exact menu names change between versions, so look for the description field within the page’s SEO settings.
After you save, Google needs to crawl the page again to update what it shows, and the displayed excerpt can still vary by search.
Common description mistakes
The most frequent problems an SEO audit finds:
- Empty description, leaving Google to decide on its own.
- Same description on dozens of pages, usually the homepage’s.
- Text too long, with the important information at the end.
- A list of keywords with no sentence.
- A promise in the summary that the page doesn’t back up.
- Description forgotten after the page changed topic.
If your site has few pages, write them all by hand. If it has thousands, like a large store, Google’s documentation allows programmatically generated descriptions, as long as they are readable by people and different from each other.
Frequently asked questions
What is a meta description? It’s a tag in the page code that summarizes the content in one or two sentences. Google may use it as the snippet shown below the title in results.
Does the meta description affect Google rankings? Google doesn’t present it as a ranking factor. It affects clicks, because it’s part of what people read before choosing a result.
What is the ideal meta description length? The usual practice is 140 to 160 characters. Google says there is no length limit, but that it truncates the snippet when needed, depending on screen width.
Does Google always use the description I wrote? No. It builds the snippet from the page and uses your description when it describes the content better. For different searches, the snippet may be different.
Do I need a description on every page? Ideally, one unique description per page. If time is short, prioritize the homepage, service pages and the pages that get the most visits.
Can I use the keyword in the description meta tag? You can and should, naturally. Repeating the word several times just makes the text sound odd.
