Keyword Difficulty (KD)
Keyword Difficulty (KD) is a 0–100 score, often from tools like Ahrefs or SEMrush, estimating how challenging it is to rank for a specific keyword in search engines. High KD indicates strong competition from authoritative sites, requiring robust backlinks and content. KD guides keyword selection for SEO campaigns. Backlink Finder’s Keyword Search helps users find guest post opportunities matching low-to-medium KD keywords, leveraging its 200,000+ domain database for targeted link-building. For instance, targeting a KD 30 keyword with a Backlink Finder-sourced backlink improves ranking chances.
