What Is a Meta Description?
A meta description is a short snippet of HTML that summarises the content of a web page. It lives in the page's head section and is not visible on the page itself, but search engines often display it beneath the page title in their results. Think of it as the advertising copy for your listing: a concise pitch that tells searchers what the page offers and why they should click.
While search engines do not always use the description you write, often pulling a more relevant snippet from the page instead, a well-crafted meta description gives you the best chance of controlling that first impression. It is one of the few elements of your search listing you can write yourself, so it deserves attention on every important page.
Length and Best Practice
Aim for roughly 150 to 160 characters. Google truncates descriptions that run too long, usually around 155 to 160 characters on desktop and fewer on mobile, so the most important words and your call to action should come early. A description that is too short wastes the space; one that is too long gets cut off mid-sentence. Writing within the limit keeps your snippet clean and complete.
Every page should have its own unique description. Duplicate descriptions across pages confuse searchers and waste an opportunity to differentiate each listing. Include the search term the page targets where it reads naturally, and write for a person rather than an algorithm.
It Influences Click-Through, Not Ranking
This is the key point: meta descriptions are not a direct Google ranking factor. Google has confirmed that the text of the meta description does not influence where a page ranks. What it does influence is the click-through rate, the share of people who choose your result over the others on the page. A compelling description can win more clicks from the same position, and stronger engagement can support your performance over time.
To write good meta descriptions, lead with the benefit, match the searcher's intent, and include a clear, active call to action such as "Get a free quote" or "Learn how". Avoid stuffing keywords, vague filler, or repeating the title word for word.

How to write an effective meta description
A good meta description reads like an advert for the page: it earns the click without over-promising. Write a distinct one for each page in an active voice, include the main term naturally because Google bolds matching words in results, and give the searcher a concrete reason to choose your result, an answer, an offer or a clear benefit. Front-load the important words in case the text is truncated, and match the promise to what the page actually delivers, since a mismatch raises bounce. Treat it as sales copy for a listing, not a summary: the job is to make your result the most clickable one on the page.
Meta descriptions and AI search
Meta descriptions matter for the classic results page, but they are not what AI answer engines quote. An AI Overview draws its summary from the page content itself, not the meta description, so the description influences click-through on standard listings rather than citation in AI answers. This is worth knowing so effort goes to the right place: write a compelling description to win clicks from the results page, and write clear, self-contained answer passages within the body to win citation in AI features. The two jobs are separate, and neither requires special markup, which Google has confirmed is unnecessary for AI visibility.
FAQ
How long should a meta description be?
Aim for around 150 to 160 characters. Google truncates longer descriptions, so put the most important words and your call to action near the start.
Do meta descriptions affect Google rankings?
No. Meta descriptions are not a direct ranking factor. They influence click-through rate, the share of searchers who choose your result, rather than your position.
Why does Google rewrite my meta description?
Google often replaces a meta description with text pulled from the page when it judges that a passage better matches the specific query. You cannot force your description to show, but a clear, relevant, well-written one is more likely to be used. Writing unique descriptions still helps.
Should every page have a unique meta description?
Yes. Duplicate descriptions across pages waste the chance to tailor each listing and can look careless to search engines. Give each important page its own description; for very large sites, prioritise the pages that matter most rather than leaving key ones blank.
