Describe the destination
Explain what a person will find and, where useful, what they can do there. Product benefits, article scope, delivery constraints or service location can be more informative than generic claims such as ‘Welcome to our website.’
Write for the page’s actual audience. Search systems may choose a passage from the visible content when it answers a query more directly, so the page itself still needs a clear introduction.
Avoid site-wide duplication
A repeated description cannot communicate why one URL is preferable to another. Generate sensible defaults for large collections, but let commercially or editorially important pages have an authored summary.
Length ranges are preview guidance, not ranking rules. Lead with the essential idea, remove filler and accept that different interfaces truncate at different points.
Implement and verify
Escape quotation marks correctly and make sure only one effective description is rendered.
<meta
name="description"
content="Delivery options, collection times and costs for Northwind Cycles orders."
/>
// Next.js App Router
export const metadata = {
description: "Delivery options, collection times and costs for Northwind Cycles orders.",
};When omission is reasonable
A generated snippet may be preferable on pages whose value changes constantly or answers many unrelated queries. Omission should be an informed choice, not a forgotten template field.
