Key Takeaways
- Prioritize long-tail keywords with monthly search volumes between 500 and 2,000 for higher conversion potential and lower competition.
- Use competitor keyword analysis within AppTweak by working through to the “Competitors” tab and selecting “Keyword Monitor” to identify gaps.
- Regularly audit your ASO keyword strategy quarterly, adjusting for seasonal trends and newly identified search terms.
- Focus on keyword relevance over sheer volume. A highly relevant keyword with 1,000 searches can outperform a less relevant one with 10,000.
- Integrate localized keyword variations for specific markets, even within English-speaking regions, using the “Localizations” feature in Sensor Tower.
App Store Optimization (ASO) keyword research is the bedrock of app discoverability, determining whether your application sinks into obscurity or surfaces in front of millions of potential users. The right keywords act as a magnet, drawing in the exact audience seeking your solution, yet many developers still rely on guesswork. This tutorial will walk through a systematic approach to uncovering those hidden gems, transforming your ASO strategy from reactive to proactive.
Step 1: Initial Brainstorming and Seed Keyword Generation
Before diving into tools, a foundational understanding of your app’s core value proposition and target audience is essential. This initial phase is less about data and more about empathy and logic.
1.1 Define Your App’s Core Functionality and User Persona
Start by articulating what your app does and who it serves. For instance, if you have a productivity app, is it a “to-do list,” a “project manager,” or a “habit tracker”? Each implies different user intent. Consider your ideal user: what problems do they face that your app solves? What language do they use to describe these problems? I often advise clients to think about the “jobs to be done” framework here. Users aren’t just downloading an app, they’re hiring it to perform a task.
1.2 Generate a Broad List of Terms
Think like a user. If you were searching for an app like yours, what terms would you type into the App Store or Google Play search bar? Include:
- Core features: “budgeting,” “photo editor,” “meditation guide.”
- Problem-solving terms: “stress relief,” “weight loss,” “time management.”
- Synonyms and related concepts: For “fitness,” consider “workout,” “exercise,” “gym.”
- Competitor names: While not for direct use in your keyword fields, knowing what users search for when looking for competitors can reveal valuable adjacent terms.
- Long-tail phrases: “best free photo editor,” “meditation for sleep.” These often convert better due to higher user intent.
Aim for a list of 50-100 initial terms. Don’t filter yet. The goal is quantity.
1.3 Use Internal Data (If Available)
If you have an existing app, look at your current analytics. What search terms are already driving downloads? Which keywords have led to high retention rates? This data, found in your App Store Connect or Google Play Console under “App Analytics” > “Acquisition” > “Search,” provides a real-world starting point. Pay close attention to terms that show a strong correlation between impressions and installs.
Step 2: Deep Dive with Keyword Research Tools
Now that you have a seed list, it’s time to quantify and expand. For this tutorial, we’ll use a combination of Sensor Tower (sensortower.com) and AppTweak (apptweak.com), two industry-standard platforms as of 2026.
2.1 Sensor Tower: Initial Keyword Discovery and Volume Analysis
Sensor Tower is excellent for identifying high-volume terms and understanding keyword difficulty.
2.1.1 Entering Seed Keywords
- Log into your Sensor Tower account.
- Navigate to the left-hand menu and select “ASO” > “Keyword Research.”
- In the search bar labeled “Enter Keywords,” input your seed list, one keyword per line, or separated by commas. Click “Analyze.”
- The platform will display key metrics: Search Volume (a proprietary score indicating search popularity), Difficulty (how competitive the keyword is), and Traffic Score.
2.1.2 Identifying Related Keywords
- After analyzing your initial list, scroll down to the “Related Keywords” section. This is gold. Sensor Tower’s algorithms suggest terms users also search for.
- Filter these related keywords by “Search Volume” (High to Low) and “Difficulty” (Low to High) to find less competitive, high-potential terms.
- Look for long-tail variations that have decent search volume but lower difficulty. For example, “meditation for anxiety” might have a lower difficulty than “meditation.”
Pro Tip: Don’t dismiss keywords with moderate search volume (e.g., 500-2,000 monthly searches). These often convert better because they indicate more specific user intent and face less competition from established apps. A common mistake I see is chasing only the highest volume terms, which are usually dominated by market leaders.
2.2 AppTweak: Competitor Keyword Analysis and Keyword Opportunities
AppTweak shines in competitive analysis and pinpointing keyword opportunities where your competitors might be weak.
2.2.1 Analyzing Competitor Keywords
- Log into AppTweak.
- From the dashboard, search for one of your main competitor apps.
- Once on their app profile, navigate to the left-hand menu and select “Keywords” > “Keyword Monitor.”
- Here, you’ll see keywords your competitor ranks for, along with their rank, search volume, and difficulty.
- Look for keywords where your competitor ranks well, but that you haven’t considered. Export this list for further analysis.
2.2.2 Discovering Keyword Gaps
- Within AppTweak, go to “Keyword Opportunities” (under the “Keywords” section).
- Add your app and 2-3 key competitors.
- AppTweak will display a matrix showing keywords where you rank, your competitors rank, and most importantly, where your competitors rank but you don’t (“Keyword Gaps”).
- Filter these gaps by “Search Volume” and “Opportunity Score.” The Opportunity Score is AppTweak’s proprietary metric that combines search volume and difficulty, indicating potential quick wins.
Expected Outcome: By the end of this step, you should have a refined list of 100-200 potential keywords, categorized by search volume, difficulty, and relevance to your app. This list will include both high-volume, competitive terms and lower-volume, high-intent long-tail keywords.
Step 3: Keyword Filtering and Prioritization
Having a large list is good, but you need to narrow it down to the most impactful terms for your app store listings. This requires a strategic approach, balancing volume with relevance and competition.
3.1 Assess Keyword Relevance
This is the most critical filter. A keyword might have massive search volume, but if it doesn’t accurately describe your app or the user’s intent, it’s useless.
- For each keyword, ask: “Would a user searching this term be genuinely interested in my app?”
- Remove any keywords that are too broad, misleading, or irrelevant. For instance, if you have a specific photo editor for portraits, “photo editor” is too broad; “portrait photo editor” is more relevant.
Common Mistake: Over-optimizing for broad terms. While tempting, these often lead to high impressions but low conversion rates because the user’s intent isn’t specific enough. Focus on relevance first.
3.2 Evaluate Competition and Difficulty
Refer back to the difficulty scores from Sensor Tower and AppTweak.
- High-Difficulty Keywords: These are often single-word, high-volume terms. If you’re a new app or in a very crowded niche, ranking for these will be extremely challenging. You might include one or two if they are absolutely central to your app’s identity, but don’t build your strategy around them.
- Medium-Difficulty Keywords: These are your sweet spot. They often have decent search volume and are attainable with a focused ASO strategy.
- Low-Difficulty Keywords: These are typically long-tail keywords. While individual terms might have lower volume, collectively they can drive significant, high-converting traffic. These are your “hidden gems.”
Editorial Aside: Many developers get hung up on chasing vanity metrics like top rankings for hyper-competitive terms. The real win isn’t being number one for “games”. It’s being number one for “offline puzzle games for adults” if that’s what your app delivers. That specific user is far more likely to convert and stick around.
3.3 Prioritize Based on a Scoring System
Create a simple scoring system (e.g., in a spreadsheet) for your remaining keywords:
- Relevance (1-5): 5 for perfect match, 1 for slight relevance.
- Search Volume (1-5): 5 for high, 1 for low (relative to your niche).
- Difficulty (1-5): 5 for very easy, 1 for very hard.
Calculate a total score for each keyword. Prioritize keywords with a high combined score, particularly those with high relevance and a good balance of volume and lower difficulty. Aim for a final list of 50-70 keywords for your initial implementation.
Step 4: Localized Keyword Research
If your app targets a global audience, localization is non-negotiable. Direct translation of keywords rarely works. Cultural nuances and search behaviors differ significantly.
4.1 Identify Target Locales
Determine which countries or regions are most important for your app. This might be based on current user data, market size, or strategic growth plans. For example, even within English, search terms in the UK, US, and Australia can vary.
4.2 Use Localization Features in Tools
Both Sensor Tower and AppTweak offer strong localization capabilities.
- In Sensor Tower, when performing keyword research, select the desired country and language from the dropdown menus at the top of the page.
- In AppTweak, navigate to your app’s profile, then select “Localizations” from the left menu. You can then analyze keywords for specific storefronts (e.g., “United States (English),” “Germany (German),” “Japan (Japanese)”).
Expected Outcome: You will uncover unique, high-performing keywords specific to each target market. For instance, “holiday” in the US might be “vacation” in the UK, or a popular local term for a specific activity might exist that has no direct English equivalent.

Step 5: Monitoring and Iteration
ASO is not a one-time task. App store algorithms change, user search behaviors evolve, and competitors launch new features. Continuous monitoring and iteration are vital.
5.1 Set Up Keyword Tracking
Add your chosen keywords to a tracking dashboard within Sensor Tower or AppTweak.
- In Sensor Tower, go to “ASO” > “Keyword Tracking.” Add your app and the keywords you’re targeting.
- In AppTweak, navigate to “Keyword Monitor” for your app and add your selected keywords.
Monitor your app’s ranking for these keywords daily or weekly. Look for fluctuations, sudden drops, or unexpected gains.
5.2 Analyze Performance Metrics
Beyond rankings, connect your ASO efforts to actual download data in App Store Connect and Google Play Console.
- Which keywords are driving impressions?
- Which keywords are leading to installs?
- What is the conversion rate from search impression to install for different terms?
This data will tell you if your chosen keywords are truly effective. A keyword might rank well but generate no downloads, indicating it’s not relevant enough. You can find more about improving conversion with App CRO: UI/UX Wins.
5.3 Quarterly Review and Adjustment
Schedule a complete review of your keyword strategy at least once per quarter.
- Remove underperforming keywords.
- Add newly discovered relevant keywords (perhaps from competitor analysis or emerging trends).
- Adjust for seasonality (e.g., “holiday planner” in Q4, “fitness tracker” in Q1).
- Re-evaluate competitor strategies.
This iterative process ensures your ASO remains agile and responsive to the dynamic app marketplace. Uncovering hidden keyword gems requires a blend of strategic thinking, diligent tool usage, and continuous analysis. By systematically moving from broad ideas to granular, data-backed decisions, you can significantly enhance your app’s visibility and attract a highly engaged user base. The ongoing effort in refining your ASO keyword strategy will yield sustained growth and a distinct competitive advantage.

How often should I update my ASO keywords?
While major overhauls are typically done quarterly, minor adjustments can be made more frequently, especially if you notice significant shifts in search trends or competitor activity. For Apple App Store, you can update your keyword field with each app version submission. For Google Play, you can update your app listing at any time.
What’s the difference between short-tail and long-tail keywords in ASO?
Short-tail keywords are broad, often one or two words (e.g., “fitness,” “games”), have high search volume, and are very competitive. Long-tail keywords are more specific phrases (e.g., “home workout app for women,” “puzzle games for adults offline”), have lower individual search volume, but indicate higher user intent and are less competitive, often leading to better conversion rates.
Should I include competitor brand names in my keywords?
Generally, no. App stores have policies against using competitor brand names to avoid misleading users. While some tools might show these terms, directly using them in your keyword fields can lead to rejection or penalties. Focus on keywords describing your app’s unique value.
How important is keyword localization for global apps?
Keyword localization is critical for global apps. Users in different regions search using different terms, slang, and cultural references. A direct translation often misses these nuances, resulting in poor discoverability. Tailoring keywords to each specific locale significantly improves visibility and download rates in those markets.
What if my app ranks well for a keyword but gets no downloads?
If a keyword ranks well but doesn’t drive installs, it likely indicates a mismatch between the keyword and your app’s actual offering, or your app’s listing (icon, screenshots, description) isn’t compelling enough to convert users who find it. Re-evaluate the keyword’s relevance and optimize your app listing’s visual and textual elements to better communicate your value proposition.
