Keyword Difficulty Checker: Bulk KD Scoring Tool

The KD score is calculated locally in your browser using a deterministic heuristic that weighs word count, commercial modifiers like buy or best, branded terms, question words, keyword length, and a seeded SERP competitiveness factor derived from the keyword itself. Scores range from 0 to 100 and stay consistent across runs.

No, it is a fast estimation tool designed for quick triage and shortlisting. For precise backlink based difficulty metrics you should still validate your final candidates with a paid SEO platform. We include SERP snapshot links on every row to make that validation easy.

No. All parsing, scoring, and export generation happens client side in your browser. Your keyword lists never leave your device, which makes the tool safe for confidential content briefs and client research.

Scores are grouped into five tiers: Very Easy (0 to 14), Easy (15 to 29), Medium (30 to 49), Hard (50 to 69), and Very Hard (70 to 100). Easier tiers suggest lower competition and faster ranking potential, while harder tiers typically require stronger domain authority and deeper content.

Each run is capped at 50 keywords to keep results fast and readable. If you paste a longer list, the tool will process the first 50 unique entries and show a warning with the skipped count. You can run additional batches by resetting and pasting the next chunk.
