Meta Description: Complete Definition & Best Practices 2025

A meta description is an HTML attribute that summarizes webpage content for search results. Creating content with proper depth and meta descriptions can significantly improve search visibility and user engagement. These descriptions impact user experience signals and click-through rates, making them crucial for both SEO performance and user interaction.
