Title tags and meta descriptions are two of the most important on-page elements for SEO, even though they don’t directly appear in your website’s visible content. The title tag is the clickable headline shown in search results and browser tabs — it should be around 50-60 characters, include your main keyword, and clearly describe the page. The meta description is the short summary (around 150-160 characters) shown below the title in search results. While it doesn’t directly affect rankings, a compelling meta description improves click-through rate, which indirectly signals relevance to Google. Every page on your website should have a unique, well-written title tag and meta description.
