Write a summary for search results

Write a unique description for every public page by hand, about 120 to 160 characters. Tell a searcher what the page offers.

By Erik Bergstedt, Agent Wranglers. Updated 20 October 2026.

How to do it

Keep the description in each page's data, next to its title. Fail the build on duplicates or on lengths outside 120 to 160 characters.

Example

<meta name="description" content="Plans for small teams and growing companies. Compare what each plan includes, see how billing works, and start a free trial today.">

How to check

Lighthouse meta-description passes, and a crawl finds no duplicates.

Measured

On a reference site, removing it dropped Lighthouse SEO from 92 to 85.
