Meta description

A meta description is the HTML <meta name="description"> tag that summarizes a page’s content. Search engines may display it as the snippet beneath the title in results, where it acts as ad copy that influences whether someone clicks. It is not a ranking factor, but a compelling, relevant description can lift click-through rate from the SERP.

How it works

The meta description populates the descriptive text under a search result’s title, though search engines frequently rewrite it — often pulling a passage from the page that better matches the specific query. That means a static description is more likely to survive for broad, brand, or navigational queries and less likely to survive for long-tail ones. Write it to summarize the page honestly, include the primary keyword (matched query terms are bolded in the snippet, which draws the eye), and add a reason to click. Keep it roughly 150 to 160 characters so it does not truncate on desktop. Missing descriptions are not penalized, but they leave the snippet entirely to the engine.

Where it applies

Descriptions matter most where the snippet competes for attention.

• Ecommerce — category and product descriptions should surface price, range, or a differentiator to win the click against comparison sites.
• Publishing — a sharp description sells the article without giving away the whole answer.
• B2B and SaaS — the snippet is a chance to qualify intent and speak to the buyer’s specific problem.
• Local — including location and service cues reinforces relevance for geo-qualified searches.

What matters from each seat

• In-house — prioritize hand-written descriptions for high-traffic and high-intent pages; templated fallbacks are fine for the long tail.
• Editorial — treat the description as a distinct microcopy discipline, not an afterthought scraped from the first paragraph.
• Engineering — provide an editable description field with a sensible auto-generated fallback, and render it server-side so it is present at crawl time.
