Keyword Difficulty Estimator (Heuristic)

Difficulty (0–100)

37

Band

Moderate

Word count

8

↓ Long-tail (5+ words) — fewer big sites target it
↓ Modifier word ("best/how/free/etc.") narrows intent

This is a free heuristic — based on keyword length, modifier presence and commercial intent. For SERP-aware scoring (DR, backlinks, content quality) you need a paid tool. For prioritising 100 ideas into "build first / build last", this works.

About this tool

What this estimator can and can't do

Real KD scores need SERP scraping + DR + backlink data — only the paid SEO tools (Ahrefs, Semrush, Moz) have it. What we CAN do for free: a length / modifier / intent heuristic that reliably tells you which 10 of your 100 ideas are worth writing first.

How the score is calculated

  • 1–2 word keyword → starts at 87 (very hard)
  • 3 words → 67
  • 4 words → 57
  • 5+ words (long-tail) → 45
  • Modifier words (best / how / free / etc.) → −8
  • Geo or year modifier → −6
  • Commercial intent (buy / coupon / price) → +10
