A meta description is the 150-160 character snippet that appears below your page title in Google search results. It's an HTML tag that summarizes what visitors will find on that page. Here's a practical example: if you're ranking for "best CMS for small business," your meta description might read: "Compare the top 5 content management systems for small businesses in 2024. Learn pricing, features, and which CMS fits your needs." That's your meta description—it appears in search results and influences whether someone clicks through to your page.
The key is writing for both search engines and humans. Your meta description should accurately reflect page content, include your target keyword naturally (in this case, "CMS for small business"), and create curiosity or value that encourages clicks. For an SEO agency's own service page offering "SEO consulting for e-commerce brands," you might write: "Our SEO consultants specialize in e-commerce optimization. Get a free audit and proven strategies to increase organic traffic and conversions." This tells searchers exactly what they'll get while hitting important keywords. Avoid keyword stuffing or misleading descriptions—Google may ignore poorly written tags, and users will bounce if the page doesn't match the description.
Length matters because Google truncates descriptions at around 160 characters on desktop and 120 on mobile. If your description is 200 characters, mobile users won't see the complete message. Each page should have a unique meta description that reflects that specific page's content, not a generic one copied across your entire site. A common mistake is writing meta descriptions that are too vague ("Welcome to our website") or too salesy without addressing user intent. When you're designing client websites, including meta descriptions in your deliverables makes a tangible difference in CTR from search results. Many CMS platforms like WordPress show a preview as you write, helping you stay within character limits and see exactly what searchers will see.
