Keyword Difficulty vs Install Volume: ASO Explained

If you’ve done any App Store Optimization work, you’ve faced this confusion:

Should I target keywords with low difficulty or keywords with high install volume?

Most apps fail at ASO not because they choose bad keywords — but because they choose the wrong balance.

This guide explains keyword difficulty vs install volume in ASO, how each works, and how to use both correctly for rankings and installs.

What Keyword Difficulty Means in ASO

Keyword difficulty shows how hard it is to rank for a keyword.

High difficulty usually means:

• Strong competitors already ranking

• Apps with high install velocity

• Long ranking history

• Strong retention and reviews

Low difficulty means:

• Fewer strong competitors

• Easier entry for new or smaller apps

• Faster ranking movement

Important:
Low difficulty does not mean low value.

What Install Volume Means in ASO

Install volume represents how many installs a keyword can generate if you rank well.

High install volume keywords:

• Bring more traffic

• Are usually broader terms

• Are more competitive

Low install volume keywords:

• Bring fewer installs per keyword

• Often more specific

• Convert better due to intent

Many new apps chase volume first — and fail.

Why You Can’t Choose Only One

Here’s the mistake most founders make:

“Let’s target high-volume keywords for more installs.”

But if your app can’t rank, volume is meaningless.

On the other hand:

“Let’s only target easy keywords.”

This can limit growth if done forever.

ASO works best when difficulty and volume are balanced.

How Keyword Difficulty vs Install Volume Works Together

Think of ASO keywords in three layers:

1. Low Difficulty + Low Volume (Foundation)

• Easy to rank

• Faster visibility

• Builds early momentum

• Improves behavioral signals

Perfect for:

• New apps

• Soft launches

• Early ASO testing

2. Medium Difficulty + Medium Volume (Growth Zone)

• Balanced competition

• Steady installs

• Most sustainable rankings

This is where most successful apps grow.

3. High Difficulty + High Volume (Scale)

• Very competitive

• Requires strong signals

• Works only after momentum

Target these only after your app has:

• Consistent installs

• Good conversion rate

• Strong retention

Why Install Volume Alone Is Dangerous

High-volume keywords often:

• Attract mixed-intent users

• Convert poorly if messaging isn’t perfect

• Require constant support from ads

Ranking #30 for a big keyword is worse than ranking #5 for a smaller one.

Why Low Difficulty Keywords Matter More Early

Low difficulty keywords:

• Help the algorithm understand your app

• Improve ranking velocity

• Create install history

• Build trust signals

These signals later help you move into higher-volume keywords.

This is how ASO compounds.

How to Choose the Right Keyword Mix

A simple rule that works:

• 60% low difficulty keywords

• 30% medium difficulty keywords

• 10% high difficulty keywords

This keeps:

• Rankings stable

• Growth predictable

• Risk controlled

Real ASO Insight (From Practice)

Apps that scale faster:

• Rank for many small keywords first

• Improve conversion before chasing volume

• Expand keyword difficulty gradually

Apps that fail:

• Go after volume immediately

• Ignore ranking feasibility

• Depend on paid installs to force rankings

Common Mistakes to Avoid

• Chasing volume without ranking potential

• Ignoring intent behind keywords

• Changing keywords too frequently

• Over-optimizing titles with hard keywords

• Not tracking ranking movement over time

Final Takeaway

So, keyword difficulty vs install volume — which matters more?

Neither alone.

• Difficulty determines if you can rank

• Volume determines how much growth you get

ASO success comes from progressive balance, not shortcuts.

Rank small → grow signals → expand keywords → scale installs.

That’s how sustainable ASO works.
