Keyword Popularity

Keyword Popularity refers to how frequently a particular keyword is searched by users in the App Store or Google Play. It is a core metric in App Store Optimization (ASO), helping app marketers understand the demand for certain search terms and prioritize which keywords to target in their metadata and Apple Ads campaigns.

Why does Keyword Popularity matter?

Keyword popularity is directly tied to app visibility and user acquisition. If a keyword is highly popular, ranking for it can bring a large volume of impressions and potential downloads. However, popular keywords also tend to be more competitive, making it harder for newer apps to achieve high organic rank.

On the other hand, less popular or “long-tail” keywords may bring fewer searches, but they often present easier ranking opportunities and higher conversion rates since users searching for them have stronger intent.

For example:

• Ranking for “photo editor” (a high-popularity keyword) can bring massive visibility but is extremely competitive.

• Ranking for “AI photo editor for selfies” (a niche keyword with medium popularity) may bring fewer searches but lead to better conversion rates.

How is Keyword Popularity measured?

Both the App Store and Google Play provide search data signals that ASO platforms interpret into keyword popularity scores. These scores reflect the relative search demand for a keyword compared to others.

Factors influencing keyword popularity include:

• Search volume: The total number of times users type the keyword into the store’s search bar.

• Seasonality: Popularity may increase or decrease depending on events (e.g., “fitness app” spikes in January).

• Trends: New app categories or cultural phenomena can create sudden jumps in keyword popularity.

• User behavior: Shifts in how users phrase queries affect demand over time.

Using Keyword Popularity in ASO and Apple Ads

Keyword popularity plays a crucial role in both organic and paid strategies:

1. Keyword research: Popularity data helps prioritize which keywords to include in your app’s metadata.

2. Balancing popularity and difficulty: Targeting only high-popularity keywords may be unrealistic. Mixing them with medium and low-popularity terms creates a more balanced growth strategy.

3. Paid campaigns: In Apple Ads, targeting high-popularity keywords ensures reach but usually comes with higher cost-per-tap (CPT).

4. Testing and iteration: Tracking shifts in popularity allows marketers to adapt campaigns in real time.

Imagine you launch a meditation app. You research keywords and find:

• “Meditation” → Very high popularity but highly competitive.

• “Sleep meditation” → Medium popularity with manageable competition.

• “Mindfulness for stress” → Lower popularity but very targeted.

By balancing all three, you can optimize your metadata for reach, discoverability, and conversions while running Apple Ads campaigns for the highest-value keywords.

Key takeaway

Keyword popularity helps app marketers identify which search terms are worth targeting. It should never be considered in isolation, combining popularity with metrics like competition, organic rank, and conversion rates ensures a smarter strategy. In ASO, the most successful apps leverage a blend of high-popularity “hero” keywords and long-tail terms that provide consistent growth.
