A 150–160 character page summary shown in Google search results. Doesn't directly affect ranking, but heavily affects click-through rate — which indirectly affects ranking.
**What it is:** the `<meta name="description">` HTML tag in your page's `<head>`. Google often (but not always) displays it as the snippet under your page title in search results.
**Whether it affects ranking:** not directly, and Google has stated this for over a decade. It's not a ranking signal in the algorithm.
**Why it still matters enormously:**
**1. CTR is a ranking signal.** When Google shows your result and users click it more often than the results above and below, your ranking improves. A great meta description that pulls more clicks moves your ranking up indirectly. A bad description that gets ignored does the opposite.
**2. Google rewrites poorly written meta descriptions.** Studies have consistently found that Google overrides ~60–70% of meta descriptions with auto-generated snippets pulled from page content. A well-written one that matches the query intent has a far higher chance of being used as-is.
**3. Truncation behavior changes by device.** Desktop typically shows ~155–160 characters; mobile typically shows ~120 characters. Front-load the most important content.
**Anatomy of a meta description that works:**
- **Includes the focus keyword** (Google bolds matching query terms in snippets — this draws the eye) - **States the unique value or angle** in the first 7–10 words - **Includes a soft call-to-action** at the end ("See pricing", "Get the checklist", "Book in 30 seconds") - **Does NOT use generic filler** ("Welcome to our site...") - **Is under 160 characters** — overrun gets truncated with "..."
**Example structure:** "[Focus keyword answer] in [time/location/qualifier]. [Specific value]. [Soft CTA]."
**Example:** "Custom HVAC websites in 4–5 weeks for $5,000 flat. Built around equipment-brand pages and financing-calculator integration. See sample builds."
**One more nuance for 2026:** with AI Overviews now appearing for many queries, your snippet may be the only piece of your page a searcher sees before deciding whether to click. The premium on a strong meta description is rising, not falling.
- **How long does SEO take to work?** — First leads from organic search: 4–10 weeks. Stable top-3 rankings for competitive terms: 6–18 months depending on domain age and competition. - **What's the difference between SEO and SEM?** — SEO = unpaid (organic) search rankings. SEM = paid search ads (Google Ads). Most marketers use SEM as a synonym for paid search; some use it as an umbrella covering both. - **Do I need to update old blog posts for SEO?** — Yes — refreshing old posts is one of the highest-ROI SEO activities, often more impactful than publishing new ones. Focus on posts that ranked positions 4–15 in the last 90 days. - **What is E-E-A-T and how do I show it?** — Experience, Expertise, Authoritativeness, Trustworthiness. Google added the second E (Experience) in December 2022. It's not a direct ranking signal but it's how Google's quality raters score sites — which trains the algorithm.
