Keyword difficulty (KD) measures how relevant a keyword is to your business.

Keyword difficulty (KD) measures how hard it would be to rank organically for a specific keyword in the top 10 search results, considering factors like the authority of competing pages. It does not measure keyword relevance. Keyword relevance, instead, refers to how closely a keyword's meaning aligns with your business, products, or services. While both are crucial for keyword strategy, they are distinct metrics. A highly relevant keyword with high difficulty might require significant SEO effort, whereas a highly relevant keyword with low difficulty presents a better immediate opportunity.
