Quick answer: to check keyword difficulty for an app store keyword, run the keyword through a checker that scores the live top 10 search results for the store and country you care about — not a cached global index. AppDrift's free keyword difficulty checker does exactly that for both the App Store and Google Play across 10 countries, returns a 0–100 score with the four-band verdict (Easy / Moderate / Competitive / Very hard), and shows you the ten apps behind the number — free, no sign-up. This guide covers how to run the check, how to read the score honestly, and what to do with it.
What is keyword difficulty?
Keyword difficulty is a 0–100 estimate of how hard it is to rank in the top search results for a keyword on the App Store or Google Play. It's computed from the apps that currently hold the top spots: how many ratings they have, how highly they're rated, how many carry the keyword in their title, and how many distinct publishers share the top 10. The higher the score, the stronger the incumbents you'd have to displace.
Difficulty matters because metadata space is brutally scarce. The App Store gives you a 30-character title, a 30-character subtitle, and a hidden 100-character keyword field [1] — roughly 160 indexed characters total. Every character you spend on a keyword you can't rank for is inventory wasted, which is why difficulty checking belongs at the start of app store keyword research, not the end.
How to check keyword difficulty for free, step by step
- Enter the exact keyword. Type the phrase a user would actually search — "habit tracker", not "an app for building habits". Check the two- and three-word variants you'd genuinely put in your metadata: in our data, phrase variants routinely score 20+ points apart from their single-word heads.
- Pick the store and country. Difficulty is computed from the live top 10 in one specific storefront. The same keyword can be Moderate in Germany and Very hard in the United States, because different apps compete in each market.
- Read the score and its band. Under 30 is Easy, 30–59 Moderate, 60–79 Competitive, 80+ Very hard. The checker also returns a popularity score — demand — which matters just as much (a difficulty of 15 on a keyword nobody searches is a trap).
- Verify against the top 10, then commit. A score is a summary; the evidence is the list of apps behind it. If the top 10 includes apps with a few hundred reviews and titles that don't contain the keyword, the field is beatable. If it's ten heavyweights with exact-match titles, believe the number and move on.
The whole loop takes under a minute per keyword with the difficulty checker, so scoring a 20-keyword candidate list is a coffee-break job, not a project.
How to read the score: the four difficulty bands
| Score | Band | What it means for your app |
|---|---|---|
| 0–29 | Easy | Winnable for a new app. Verify demand exists, then put it in your title or subtitle. |
| 30–59 | Moderate | The realistic contested zone for most indie apps — winnable with well-matched metadata and some download velocity. |
| 60–79 | Competitive | Established apps hold the top spots. Target only if you already have traction; otherwise chase a longer-tail variant. |
| 80–100 | Very hard | Dominated by household names. Ranking is unrealistic for most apps — spend the characters elsewhere. |
Calibrate your expectations with real numbers: when we scored 604 live checks for our iOS vs Android keyword difficulty study, generic single English words on iOS — "sleep" (90), "calendar" (88) — were fortresses, and even "habit tracker" scored 84. The realistic hunting ground on iOS was the 41–60 range, which held 37% of all scored keywords.
What the difficulty score is calculated from
A difficulty score you can't interrogate is a vibe with a number attached. AppDrift's model is published in full: every check pulls the live top 10 search results and weighs four factors — review strength (40%), the log-scaled review counts of the ranking apps; rating quality (20%), their average star rating; title match (20%), how many carry the keyword in their title; and publisher diversity (20%), how many distinct developers hold the ten spots. The same scorer runs on both platforms, and the 604-check dataset behind it is public.
Whatever tool you use, apply one test: does it tell you why a keyword scored what it scored, and does it check live results or a cached index? If a tool won't show its methodology, treat its difficulty numbers as decoration.
Can I check keyword difficulty manually?
Yes — and it's worth doing once to understand what the scores compress. Search your keyword in the store, then audit the top 10 by hand: How many results have six- or seven-figure rating counts? How many contain the exact keyword in their title? Are the ten slots held by ten different publishers, or three? Apple's own guidance confirms the inputs that matter — title, keyword field, and engagement signals drive search ranking [2].
The manual method's limits are practical: it takes 10–15 minutes per keyword, it's inconsistent between checks, and you can't see popularity at all. The free checker automates exactly this audit — same inputs, same logic, one second — which is why the manual route makes sense as education and the automated one as workflow.
Is keyword difficulty different on iOS and Android?
Substantially, and in a direction most developers don't expect. Across our 604-check dataset, iOS keywords averaged 61.7/100 against 44.1/100 on Google Play, and not one of 193 Android keywords scored above 73 — the App Store's generic terms are simply more fortified. But Android carries its own catch: Google Play's public search returns only ~25–30 visible results for most queries (the median in our data was exactly 30, versus 200 on iOS), so an Android keyword is a fight for one of thirty slots. Easier entry, smaller door.
Two practical rules follow. Never copy a keyword set from one platform to the other without re-checking difficulty per store, and never compare an Android score against an iOS score — the popularity inputs differ too (install volumes on Play, review volumes on the App Store), so scores are only comparable within a platform.
What to do once you know the difficulty
If a keyword scores too high, the fastest fix is usually to add a word. Across 862 scored checks, one-word iOS keywords averaged 70.1 difficulty against 53.4 for three-word phrases — our long-tail difficulty data shows how far that trick goes before it stops working.
Difficulty is one gate of three — a keyword earns a metadata slot when demand, difficulty, and relevance all pass. Once a keyword scores as winnable, check where you currently stand for it with the free app store rank checker: already ranking 11–30 means a title or subtitle placement can push you into the visible zone.
Then place it deliberately. Your strongest winnable keyword belongs in the title, the next tier in the subtitle, and the long tail in the 100-character keyword field — our iOS keywords field guide covers the mechanics, and the free keyword space calculator tells you whether your winners actually fit before you're editing metadata in App Store Connect.
Finally, treat difficulty as a moving number. Top tens churn — apps rise, rebrand, and retitle — so a keyword that scored 65 in March can be a 52 by August. AppDrift's keyword tracking re-scores difficulty and popularity beside every tracked keyword's daily rank from $9.99/month, which turns the quarterly re-check from a chore into a dashboard glance.
Frequently asked questions
How can I check keyword difficulty for free?
Use the free keyword difficulty checker — it scores any App Store or Google Play keyword 0–100 from the live top 10 in 10 countries, shows the ranking apps behind the score, and needs no sign-up. Free checks are rate-limited but not feature-limited: the scorer is the same one AppDrift's paid tracker uses.
What is a good keyword difficulty score for a new app?
Under 60. The 0–29 band is a genuine easy win when demand exists, and 30–59 is the realistic contested zone where matched metadata and early velocity can crack the top 10. In our study data, everything above 80 was held by long-established apps — effectively closed to new entrants.
Is keyword difficulty the same as search volume?
No. Difficulty measures competition; search volume (popularity) measures demand. You need both: a keyword worth targeting scores high on popularity and low-to-moderate on difficulty. Checking one without the other is how apps end up ranking #1 for terms nobody searches.
How often should I re-check keyword difficulty?
Quarterly, and always before you commit a metadata update. Difficulty shifts as the top 10 changes. For the keywords that drive your installs, daily tracking with automatic re-scoring catches the shifts — including the happy kind, where a competitor's exit turns a 65 into a keyword you can take.
