Keyword Difficulty (KD) is a measure of how hard it is to rank for a specific keyword in search engines. It looks at factors like the strength of competing websites, their content quality, and backlinks. A higher KD means more competition, making it tougher for new sites to get noticed. Understanding this helps you choose the right keywords for your SEO strategy—whether you want to chase popular terms or focus on less competitive ones that might attract a more targeted audience.
