A meta description is a snippet of text you add to a page's HTML that tells searchers what the page covers. It sits in the <head> section as <meta name="description" content="Your text here"> and shows up in Google's search results underneath your title tag. The recommended length is 150–160 characters because Google typically truncates anything longer, though mobile results sometimes cut off earlier around 120 characters. Meta descriptions don't carry ranking weight—Google confirmed this years ago. Their value is purely promotional. A well-written description improves your click-through rate, which can indirectly signal relevance and drive more traffic. Think of it as ad copy for organic search. If you skip writing one, Google pulls text from your page, often grabbing the first sentence or whatever section matches the query. That auto-generated snippet usually reads poorly and wastes the opportunity to sell the click. Good meta descriptions include the primary keyword naturally, match search intent, and create urgency or curiosity without clickbait. For local businesses in Ottawa or Toronto, mention the city if location matters to the searcher. For e-commerce, include price ranges, brands, or availability. For service pages, lead with the benefit or outcome. At Ottawa SEO, we write unique descriptions for high-value pages—homepage, key service pages, top blog posts. For sites with hundreds of pages, we template descriptions for scale, using variables like {{city}} or {{category}} to avoid duplicate content. We don't stress if Google rewrites them for certain queries; their algorithm sometimes pulls better-matching text, and that's fine. Common mistakes: stuffing keywords, writing the same description across multiple pages, exceeding 160 characters, or being vague. Treat each description as a micro pitch. If someone sees ten blue links, yours should answer why they'd click yours over a competitor's.
