What is a meta description, and does it improve rankings?
The meta description is an HTML tag in a page's header that sums up its content in a sentence or two. On Google's results page it most often supplies the gray text shown under the blue title and the URL: the snippet.
<meta name="description" content="Your description">
The tag goes in the <head> of the page, next to the <title> tag.
It is not a ranking factor: Google states it does not use it to order results. Its role is elsewhere. A clear description makes people want to click, and one more click at the same position is traffic gained without touching your ranking. Think of it as a shop window: it does not put you on the street, it decides whether people walk in.
The page title does count for SEO. Work the meta description for click-through rate, the title for both.
What is the ideal meta description length?
Google publishes no official limit. It cuts the snippet by display width, not by character count, which is why a text full of “m” and “w” is cut sooner than one full of “i” and “l”. The benchmarks below are orders of magnitude commonly observed.
| Element | Width benchmark | Characters (order of magnitude) |
|---|---|---|
| Page title | about 580 pixels | 50 to 60 characters |
| Description on desktop | about 920 pixels | 120 to 155 characters |
| Description on mobile | about 680 pixels | 90 to 120 characters |
The tool measures the real width of your text in your browser, in Arial (20 px for the title, 14 px for the description), and compares it to these benchmarks. If you target both screens, put the essentials in the first 110 characters: that is what a phone shows. Also avoid descriptions under 70 characters, which leave room unused.
Why does Google rewrite my meta description?
Google says it generates the snippet from the page content and uses the meta description only when it describes the page better than the text it can extract. So it often replaces it, and the result can vary from one query to another for the same page. Common causes:
- It does not answer the search — If someone searches “waterproof hiking boots” and your text talks about shipping, Google prefers a passage of the page about waterproofing.
- It is missing, too short or too long — An empty or few-word description is replaced; one that is too long is cut.
- It is identical across pages — A text repeated everywhere carries no information specific to the page.
- It is stuffed with keywords — A comma-separated list of words is not a readable description.
You cannot force Google to show your text. You can, however, lower the odds of being rewritten: a unique description, faithful to the page, that uses the words of the query you target.
How do you write a good meta description?
- 1
Start with the target keyword
Google bolds the search words in the snippet. Using them early reassures people the page is relevant.
- 2
Give a concrete benefit
Not “the best choice” but a verifiable fact: material, use, sizes, delivery time.
- 3
Add a reassurance
Returns, warranty, shipping: a reason to pick your store over another.
- 4
End with a call to action
A verb that invites the click: discover, compare, shop.
- 5
Write for one specific page
One description per page, written by hand at least for your main pages.
The tool controls length, keyword presence in the title and the description, the call to action and whether the description just copies the title.

Which mistakes should you avoid in a meta description?
- Duplicates — The same description on dozens of product pages, often because a theme template generates it. Every page deserves its own, or at least a sentence of its own.
- Keyword stuffing — “Men jacket, rain jacket, waterproof jacket cheap”: unreadable, and rarely kept by Google.
- Copying the title — Repeating the title says nothing more. The tool flags it when the description reuses almost every word of the title.
- Unescaped double quotes — In the tag, a straight quote closes the content attribute: the text is cut at that point. Use curly quotes or ', or escape it as ". The tool's button does it for you.
- False or vague promises — “Best price guaranteed” or “24-hour delivery” that the page does not back up: a disappointed visitor does not come back.
- No call to action — A purely descriptive text informs, but does not invite the click.
Where do you edit the meta description on Shopify, WooCommerce and PrestaShop?
| Platform | Where to edit it |
|---|---|
| Shopify | On the product, collection or page: Search engine listing block, Edit button, Meta description field. For the homepage: Online Store > Preferences. |
| WooCommerce | WordPress has no native field: use the site's SEO plugin, which adds a box with a preview under the product or page editor. |
| PrestaShop | Product page: SEO tab, Meta description field. Categories: Catalog > Categories, then the category's SEO section. |
After a change, the snippet does not update in Google right away: the page has to be crawled again, which can take from a few days to a few weeks. Also check your product titles in the feed with the product title scorer.
Meta description and Google Merchant Center: what is the link?
If you sell with Google Shopping, your pages are not only read by shoppers: Google also visits them to check that your feed tells the truth. Product pages that say something other than the feed declares, pages with generic or misleading descriptions, legal notices that cannot be found: all of these weigh on the trust placed in the store.
Polishing your descriptions helps the click, but does not replace compliance across the whole site. To see what a Google reviewer would flag on your store, run the free audit. To check the essentials yourself, go through the Google Merchant Center compliance checklist.
Frequently asked questions
How long should a meta description be?
Google sets no official limit: it cuts by display width. In practice aim for 120 to 155 characters, roughly 920 pixels on desktop, and put the essentials in the first 110 characters to stay readable on mobile (about 680 pixels).
Is the meta description a ranking factor?
No. Google has stated it does not use it to rank pages. It does influence click-through rate, though, since it is often the text shown under the title in results.
Why does Google not show my meta description?
Google generates the snippet from the page and uses the meta description only if it describes the page better than the text it can pull. It is often replaced when it does not match the search, or when it is missing, too short or duplicated.
Does every page need a meta description?
Ideally yes, and each one should be unique. On a catalog of hundreds of products, write the main pages by hand (homepage, categories, best sellers) and use a template that inserts the name, the main feature and the brand for the rest.
Should the keyword be in the meta description?
Yes, naturally. Google bolds the search words found in the snippet, which catches the eye and confirms relevance. Without stuffing: one clear mention is enough.
Can you use quotes or special characters?
Avoid straight double quotes, which close the HTML attribute and cut the text. Use curly quotes, the apostrophe, or write ". Accents, the euro sign and dashes are safe.
What is the difference between the title tag and the meta description?
The title is the clickable blue headline: it counts for SEO and should contain the main keyword. The meta description is the gray text below: it does not count for ranking but partly decides the click.
