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.

Why keyword gaps matter for ASO
Two apps in the same category rarely rank for an identical set of keywords. The overlap shows where you compete directly; the difference shows where one app has found demand the other hasn't. When a competitor ranks for a keyword you don't, that's a concrete, validated opportunity — someone is already proving the keyword drives installs. Sort those gap keywords by difficulty and search volume, pick the low-difficulty ones with real demand, and work them into your title, subtitle, and keyword field. Then track them so you can watch your rank climb.
Difficulty and search-volume figures are model estimates derived from public app-store data — not official Apple or Google numbers. Use them directionally.
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. Each keyword shows estimated difficulty and monthly search volume.
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?
Prioritize gap keywords that pair low difficulty with real search volume — those are the easiest wins. A keyword a competitor ranks well for but you don’t is a direct signal of demand you’re missing in your title, subtitle, or keyword field.
Are these official Apple or Google numbers?
No. Difficulty and search-volume figures are model estimates derived from public app-store data, not official Apple or Google metrics. Ranks reflect ASOTrendHQ’s most recent checks. Use everything directionally.
