A meta description is the short summary you write for a page in its HTML. Search engines may show it under your title in the results, which makes it one of the few places where you can directly persuade someone to click. Here’s what matters and what doesn’t.
What Google actually does with your description
Google’s documentation is clear on a few points:
- Google mostly builds snippets from your page content, tailored to each search. It uses your meta description when it describes the page better than other parts of the content. So a good description raises the odds it’s shown, but it isn’t guaranteed.
- There’s no length limit for the tag itself. Google truncates the snippet it displays to fit the screen.
- Each page should have its own description. Identical or near-identical descriptions across a site aren’t helpful.
- Keyword lists don’t work. Long strings of keywords don’t tell people what the page is about, and such descriptions are less likely to be shown.
- Generated descriptions are fine on large sites, as long as they read naturally and vary from page to page.
How long should a meta description be?
Since Google truncates to fit the device, aim to put the most important information in roughly the first 120 characters, and keep the whole description to about 150–160 characters. That’s a working rule for what usually displays, not a Google requirement. Our free Meta Description Generator shows the character count as you write.
A four-part formula
- What the page is — the topic or product, in the words people search for.
- What’s specific — a number, a format, a price, a date, a feature.
- Who it’s for or the problem it solves.
- What happens next — read, compare, try free, download.
Not every description needs all four. Two strong parts beat four weak ones.
Examples by page type
Guide
Weak: “Read our complete guide to email marketing for businesses.”
Better: “Set up a welcome email series in an afternoon: the five emails to send, when to send them, and subject lines you can copy.”
Product page
Weak: “Buy our amazing ceramic mug. Best quality. Free shipping.”
Better: “Hand-glazed 350 ml stoneware mug, dishwasher and microwave safe. Ships in 2–3 days; free returns within 30 days.”
Comparison
Weak: “Zapier vs Make vs n8n comparison.”
Better: “Zapier, Make and n8n compared on free plans, how usage is counted, hosting and code steps, with official sources for every fact.”

Every detail in a description must be true on the page. A description that promises something the page doesn’t deliver earns the click once and loses the visitor.
Using AI to draft descriptions
AI is useful for first drafts, especially across many pages. Give it the page’s real content and constraints:
Write 3 meta descriptions for the page below.
Rules: 140–155 characters each; start with what the page is; include one specific
detail from the text; no keyword stuffing; no claims that aren't in the text;
end with what the reader can do next.
Page title: [title]
Page content: [paste the key paragraphs or bullet points]
Then pick one, check every fact against the page, and adjust the wording to match how your customers talk. Pair it with a strong title from our Meta Title Generator and a clean URL from the SEO Slug Generator.
A quick checklist before you publish
- Is it unique to this page?
- Does the first half say what the page is?
- Is there at least one specific detail?
- Is every claim true on the page?
- Does it read like a sentence, not a keyword list?
Sharing the page on social media or in messaging apps? Those link previews are built from Open Graph tags (og:title, og:description and og:image) when your page has them. Our Open Graph Tag Generator creates them with a live preview.
