Keyword Opportunity Score Calculator

The formula behind the opportunity score

Four inputs are each converted to a 0 to 100 sub-score, search volume scaled against a 5,000-search ceiling, ease of ranking as 100 minus keyword difficulty, commercial value scaled against a $10 CPC ceiling, and business relevance scaled from a 1 to 5 self-rating, then combined using fixed weights of 30 percent volume, 35 percent ease, 15 percent commercial value and 20 percent relevance.

Why ease of ranking carries the most weight

Ease of ranking gets the largest single weight because a keyword with excellent volume and commercial value is worth little if it takes years of authority-building to rank for it. Relevance is weighted above raw commercial value because a keyword that closely matches what you actually sell will convert the traffic it does bring far better than a tangentially related one with a higher CPC.

What this score cannot account for

The formula treats every keyword independently and has no way to know your current site authority, existing content, or how a keyword fits into a broader topic cluster. Two keywords with an identical score can still have very different real-world priority once you factor in whether you already rank nearby, or whether ranking for one would cannibalize another page you own.
