Find the keyword gap between two apps
Pick two apps and I'll show you the keywords they both rank for — and, more usefully, the ones each ranks for that the other is missing. That gap is where your next ASO wins hide. No signup, runs on ASOTrendHQ's live data.
Watch competitor gaps over time
Add your app to track competitors continuously — get alerted when a rival starts ranking for a keyword you don't. Free, no credit card.
Why keyword gaps matter for ASO
Keyword overlap and gaps show differences in the available catalog associations and collected positions. They help identify terms to inspect against your app's features. A competitor position alone does not establish searches, installs, or an opportunity.
Review source dates, store, market, and app relevance before planning a metadata experiment. Demand remains unavailable without an authorized source; difficulty is not assessed.
Frequently asked questions
What is a keyword gap analysis?
A keyword gap analysis compares two apps and finds keywords one ranks for that the other does not. Those gaps are opportunities: keywords a competitor is already winning that you could target. This tool also shows the keywords both apps share, so you can see where you compete head-to-head.
How do I compare two apps’ keywords?
Search and select two apps — yours and a competitor, or any two apps. The tool fetches the keywords each one ranks for and splits them into three lists: shared keywords (with both apps’ ranks side by side), keywords only the first app ranks for, and keywords only the second ranks for. Demand and difficulty remain unavailable without qualified evidence.
Is the keyword gap tool free?
Yes — it’s free with no signup. It runs on ASOTrendHQ’s catalog of tracked apps and 235k+ keywords across the Apple App Store and Google Play.
How should I use the gaps I find?
Treat gaps as candidates to investigate. A competitor position does not establish search demand or a missing metadata opportunity. Check app fit, store, country and observation date before planning an experiment.
Are these official Apple or Google numbers?
Positions require a named source and observation date. Search demand and ranking difficulty remain unavailable without qualified evidence.
