Usage Examples

Just ask your AI assistant naturally:

"How competitive is the 'fitness' keyword in the US?"

"Analyze Spotify's competitors and find keyword opportunities"

"Generate an ASO report for com.spotify.client"

"Compare 'music' and 'podcast' keywords across US, UK, and DE markets"

"Do a keyword gap analysis: Spotify vs Apple Music"

"Analyze Shazam's user reviews"

"Suggest title and subtitle for my fitness app targeting: workout, training, exercise"

"Discover keywords for a new calorie tracking app"

"Update my app's subtitle to 'AI Workout Planner' on App Store Connect"

"Show all locales and metadata status for my app"

Scoring Algorithm

The server calculates its own scores, independent of Apple Search Ads API:

Score

Description

Visibility

Based on rating, review count, and ranking position

Competitive

Difficulty derived from the strength of top-ranking apps

Opportunity

High traffic + low difficulty = high opportunity

Overall

Weighted combination of all scores (0-10)

When the aso npm package fails to reach Apple (503 errors), the server automatically falls back to custom scoring using search result analysis. Scores are always available.
