Response Sections

`shared` — Keywords Both Apps Rank For

Keywords where both your app and the competitor appear in search results. Use rankDiff to see who ranks higher.

`yourUnique` — Your Strengths

Keywords that only your app ranks for. These are your competitive advantages — keywords where you have visibility and the competitor does not.

`competitorUnique` — Opportunities to Target

Keywords that only the competitor ranks for. These represent opportunities — keywords you could target to gain visibility in spaces where the competitor already has traction.

`gapAnalysis` — Threats

Keywords where the competitor significantly outranks you. These are threats — high-value keywords where you’re losing ground and should consider optimizing.

Keyword Entry Fields

Field	Type	Description
keyword	string	The search keyword
yourRank	number\|null	Your app’s rank (null if your app doesn’t rank for this keyword)
competitorRank	number\|null	Competitor’s rank (null if competitor doesn’t rank for this keyword)
rankDiff	number\|null	`yourRank - competitorRank`. Positive = you rank better. Null if one app doesn’t rank.
volumeScore	number	Estimated search volume score (0–100)
difficulty	number	Ranking difficulty score (0–100)

Summary Fields

Field	Type	Description
totalShared	number	Number of keywords both apps rank for
totalYourUnique	number	Number of keywords only your app ranks for
totalCompetitorUnique	number	Number of keywords only the competitor ranks for
totalGaps	number	Number of keywords where competitor significantly outranks you
overlapPercent	number	Percentage of keywords shared between both apps (0–100)

Both apps must have keyword data. Before using this endpoint, call GET /v1/apps/:id/keywords for both your app and the competitor to trigger keyword discovery. If either app has no keyword data, the comparison will be incomplete or empty.

Competitive ASO strategy: Focus on competitorUnique keywords with high volumeScore and low difficulty — these are the easiest wins for expanding your keyword footprint. Then address gapAnalysis keywords where you’re being outranked on important terms.

Errors

Status	Code	When
400	INVALID_APP_ID	Non-numeric or missing app ID
400	MISSING_PARAMS	Missing `appId` or `competitorId`
401	UNAUTHORIZED	Missing or invalid API key
429	RATE_LIMITED	Too many requests — slow down
500	INTERNAL_ERROR	Server error during comparison
