Beyond Volume: Why Difficulty Matters

Targeting only high-volume keywords is a trap—they are often dominated by giant apps. Keyword difficulty measures how hard it is to rank for a term, and pairing it with volume reveals where you can actually win.

The Three Core Inputs

Every keyword decision balances three numbers:

  • Volume – how many people search it.
  • Difficulty – how strong the competition is.
  • Relevance – how well it fits your app.

A keyword needs all three to be worth pursuing.

How Difficulty Is Estimated

Difficulty scores typically combine signals from the top-ranking apps for a term: their ratings count, review velocity, age, and how tightly their metadata targets the keyword.

Many apps with thousands of reviews ranking for a term means high difficulty.

A Simple Opportunity Formula

An opportunity score rewards high volume and relevance while penalizing difficulty. A common shape:

opportunity = (volume * relevance) / difficulty

# Higher score = better target
# relevance and difficulty on 0-1 scale
# volume normalized to 0-100

Worked Example

Compare two keywords for a budgeting app:

Keyword A: volume=90, relevance=0.4, difficulty=0.9
  score = (90 * 0.4) / 0.9 = 40

Keyword B: volume=50, relevance=0.9, difficulty=0.3
  score = (50 * 0.9) / 0.3 = 150

-> B is the far better target

Computing It in Code

You can script opportunity scoring to rank a whole keyword list at once.

def opportunity(volume, relevance, difficulty):
    return (volume * relevance) / difficulty

kw = [("budget tracker", 50, 0.9, 0.3),
      ("finance", 90, 0.4, 0.9)]

for name, v, r, d in sorted(kw, key=lambda x: -opportunity(x[1], x[2], x[3])):
    print(name, round(opportunity(v, r, d), 1))

The Low-Hanging-Fruit Zone

The sweet spot is moderate volume, low difficulty, high relevance. New apps should win these first to build ranking momentum before attacking competitive head terms.

Why Relevance Caps Opportunity

A high-volume term you barely fit will not convert and may hurt rankings as users bounce. Always weight relevance heavily—ranking for the wrong keyword wastes installs and signals.

Reassessing as You Grow

Difficulty is relative to your strength. As your app gains reviews and ranking authority, terms that were too hard become reachable.

Recompute opportunity scores periodically and graduate to tougher keywords over time.

Building a Prioritized Roadmap

Turn scores into a plan:

  • Sort candidates by opportunity score.
  • Place top scorers in title/subtitle.
  • Assign mid-tier terms to keyword field or description.
  • Park very hard terms for later.

Pitfalls in Scoring

Watch out for:

  • Trusting a single tool difficulty as absolute truth.
  • Ignoring relevance to chase big numbers.
  • Never re-scoring after the app grows.

Use scores to prioritize, not as gospel.

Quick Check

Test your understanding of opportunity scoring.

Recap: Difficulty & Opportunity

You learned to prioritize keywords by value, not just volume:

  • Balance volume, difficulty, and relevance.
  • Use an opportunity score to rank candidates.
  • Win low-hanging fruit first, then graduate to harder terms.
  • Recompute as your app gains authority.
