Meta Description
In one line
The meta description is the short page summary shown below the title in search results — not a direct ranking factor, but a major lever on click-through rate.
Going deeper
The meta description lives in `<meta name="description" content="...">` inside the `<head>`. Google has explicitly stated it is not a direct ranking factor — but it shapes CTR, and pages that earn clicks consistently get surfaced more often, so the practical effect is an indirect ranking lift. Treat it as an indirect ranking signal, not a cosmetic field.
Target around 155–160 characters on desktop, ~120 on mobile. A reliable structure is `problem framing + value proposition + soft CTA`, one sentence each. Example: `Struggling to measure GEO? villion shows your citations across ChatGPT, Perplexity and Google AI Overview in one dashboard. Start free.` Use the primary keyword once or twice naturally, and dial back superlatives — `best`, `#1`, `ultimate`. Tighter, more specific copy tends to outclick puffery.
The most common failure is leaving the field blank and letting the CMS auto-generate from the body. Google then chops awkward fragments out of paragraph one, and you end up with the same auto-meta sprawling across the site. The second mistake is restating the title nearly verbatim — that wastes one of the two visible lines on duplicate information. If the title is `what`, the description should be `why` and `how`.
Meta description gets more interesting in the GEO era. AI search engines often use the meta description as a quick page summary when scoring citation candidates, before reading the full body. Writing it as a clean factual sentence — something an AI could quote verbatim — measurably increases the odds of being lifted into AI Overview or Perplexity answers. The same line also powers SERP cards, social share previews and messenger link cards, so a short, fact-first description compounds across surfaces.
Worth knowing: per a large Ahrefs study, Google ignores your written description and pulls a body snippet instead about 60% of the time. The fix is to write the first paragraph of every page as a clean, citable definition of what the page answers — that way both your meta and Google's auto-snippet read well. A simple Search Console check, comparing CTR on hand-written vs. auto-generated pages, usually makes the ROI obvious within a quarter.
