What is KEI?

The Keyword Efficiency Index (KEI) is a mathematical model that measures the ratio of a keyword's search demand against its competitive resistance. Originally developed by Sumantra Roy, KEI helps SEO professionals and digital marketers quickly identify whether a keyword represents a profitable, rankable opportunity — or a saturated dead-end with too many established competitors to displace.

A high KEI means many people are searching but few pages are competing directly, creating a clear window for new content to rank efficiently. This tool extends the classic formula by layering in CPC as a commercial intent multiplier, giving you a more actionable, revenue-weighted score.

How To Use This Tool

Step 1: Find your keyword's monthly search volume in Google Ads Keyword Planner, Ahrefs, or Semrush. Enter it in the search volume field.

Step 2: Open Google and search allintitle:"your keyword". The number of results shown is your competing pages count — the true competitive density signal.

Step 3: Grab the CPC (cost-per-click) value from your keyword tool. Higher CPC = stronger buyer intent. Enter it to boost your KEI weighting for commercial terms.

Step 4: Run the check. Compare multiple keywords using the History table to build a stack-ranked list of your best targets.

KEI Score Thresholds

Scores are calculated using a normalized opportunity model that accounts for competition volume at real-world scale (hundreds of thousands of URLs).

Score Range	Category	Action
80 – 100	Golden Niche	Priority target
40 – 79	Viable Node	Build long-tail cluster
0 – 39	Red Ocean	Pivot or skip

Why CPC Matters in KEI

Traditional KEI ignores commercial intent, treating a keyword like "best CRM software" (CPC $12) the same as "what is CRM" (CPC $0.20). That's a critical blind spot for anyone focused on revenue, not just traffic.

This tool applies a CPC multiplier to the base KEI score, rewarding keywords where advertisers are willing to pay more per click — because if advertisers bid high, buyers are converting. The result is a revenue-weighted opportunity score that surfaces keywords worth ranking for, not just keywords that are rankable.
