Sensor Tower ASO: Win App Discoverability Now

For any app developer or mobile-first business, mastering App Store Optimization (ASO) is no longer optional; it’s the bedrock of discoverability and user acquisition. Effective ASO, much like search engine marketing, ensures your app gets seen by the right people at the right time, but the tools and tactics are distinct. This guide will walk you through a powerful, often underutilized, platform for supercharging your app’s visibility through intelligent keyword research and competitive analysis, covering topics such as app store optimization (ASO) and broader mobile marketing strategies. Ready to stop guessing and start dominating the app stores?

Step 1: Setting Up Your App in Sensor Tower for Initial Analysis

Before you can even think about keyword research or competitive analysis, you need to tell Sensor Tower which app you care about. This seems basic, but I’ve seen countless marketing teams jump straight into keyword reports without properly configuring their project, leading to skewed data and wasted time. Don’t be that team.

1.1 Create a New App Project

1. Log in to your Sensor Tower account. On the left-hand navigation panel, locate and click on “App Intelligence.”
2. Within the “App Intelligence” dashboard, look for the “My Apps” section. You’ll see a prominent button, usually near the top right, labeled “+ Add App.” Click it.
3. A pop-up window will appear. Here, you’ll need to enter your app’s name or its App Store/Google Play Store URL. For accuracy, I always recommend using the URL if you have it. Select the correct platform (iOS or Android) and the primary country/region for your analysis. For instance, if your target market is the US, select “United States.”
4. Click “Add App.” Sensor Tower will then pull in your app’s basic data.

Pro Tip: Don’t just add your own app. Go ahead and add your top 3-5 direct competitors at this stage too. It saves time later and gives you immediate context for performance benchmarks. I always set up a “Competitor Watchlist” folder within Sensor Tower for this exact purpose.

Common Mistake: Forgetting to select the correct country. Your keyword rankings and search volumes are highly localized. Analyzing for the UK when your primary market is Canada will give you completely irrelevant data.

Expected Outcome: Your app, along with key competitors, will now be listed under “My Apps,” ready for deeper analysis. You’ll see basic metrics like current rank and category.

Step 2: Mastering Keyword Research with the Keyword Tool

This is where the real magic happens for ASO. Keywords are the lifeblood of app discoverability. If users can’t find your app, you don’t have users. Period. Forget vanity metrics; focus on what people are actually typing into the search bar.

2.1 Initial Keyword Brainstorming and Volume Check

1. From your “App Intelligence” dashboard, navigate to the left-hand menu and click on “Keyword Research.”
2. Select your app from the dropdown at the top of the page. Ensure the correct country is selected (e.g., “United States”).
3. In the “Keyword Tool” section, you’ll see an input field. Start by entering broad, relevant terms related to your app. For example, if your app is a meditation guide, you might start with “meditation,” “mindfulness,” “sleep.”
4. After entering a term, click “Add Keyword.” Sensor Tower will display crucial metrics: Search Volume (a proprietary score indicating search popularity), Difficulty (how hard it is to rank for), and Traffic Share (the percentage of traffic that keyword drives to your app, if you’re already ranking).
5. Repeat this for 10-20 initial keywords.

Pro Tip: Don’t just rely on what you think. Ask your early users what terms they would use to find an app like yours. This user-centric approach often uncovers unexpected, high-intent keywords. We once found “budget tracker for students” was a goldmine for a finance app after a user focus group, despite our internal team focusing on “personal finance management.”

Common Mistake: Chasing only high-volume keywords. A keyword with a Search Volume of 80 but a Difficulty of 95 is often a waste of effort for a new app. Aim for a balance, focusing on terms with decent volume (e.g., 40+) and manageable difficulty (e.g., below 70).

Expected Outcome: A list of potential keywords with their respective search volume and difficulty scores, giving you a preliminary idea of their viability.

2.2 Leveraging Keyword Suggestions for Long-Tail Opportunities

1. Still within the “Keyword Tool,” after adding your initial terms, scroll down. Sensor Tower provides a powerful section called “Keyword Suggestions.”
2. This section offers various filters: “Related Keywords,” “Competitor Keywords,” “Long-Tail Keywords,” and “Trending Keywords.”
3. Click on “Related Keywords.” This will show you terms semantically linked to your initial input. Look for terms with good Search Volume and lower Difficulty than your broad terms.
4. Next, click on “Long-Tail Keywords.” These are often phrases of three or more words. While individual long-tail keywords might have lower search volume, they often indicate higher user intent and are significantly easier to rank for. Add any promising ones to your list.
5. Periodically check “Trending Keywords” to see if any seasonal or current event-related terms could temporarily boost your visibility.

Pro Tip: Pay close attention to the “Search Ads Intelligence” section within Sensor Tower’s Keyword Tool. It shows you which keywords your competitors are bidding on in Apple Search Ads. This is an incredible shortcut to identifying high-value, high-intent terms they’ve already validated with ad spend. If they’re paying for it, it’s probably converting.

Common Mistake: Ignoring long-tail keywords. While “meditation” is competitive, “guided meditation for anxiety relief” might have lower volume but a much higher conversion rate because the user knows exactly what they want. Don’t underestimate the power of specificity.

Expected Outcome: An expanded list of keywords, including valuable long-tail and related terms, forming a robust foundation for your ASO strategy.

Step 3: Uncovering Competitor Strategies with Keyword Spy

You’re not operating in a vacuum. Your competitors are likely doing ASO too, and probably making mistakes you can learn from, or finding opportunities you’ve missed. The “Keyword Spy” tool is your secret weapon for competitive intelligence.

3.1 Analyzing Competitor Keyword Rankings

1. From the left-hand menu, under “App Intelligence,” select “Keyword Spy.”
2. In the “Competitor App” dropdown at the top, select one of your previously added competitor apps. Again, confirm the correct country.
3. Sensor Tower will display all the keywords that competitor is currently ranking for, along with their Rank, Search Volume, and Difficulty.
4. Filter this list by “Rank” (ascending) to see their highest-performing keywords. Look for terms where they rank highly (e.g., top 10) that you either aren’t targeting or are ranking poorly for. These are immediate opportunities.
5. Additionally, check the “Keyword Change” column. If a competitor has recently jumped significantly for a keyword, it might indicate they just optimized for it, or it’s gaining traction.

Pro Tip: Don’t just copy. Analyze why they might be ranking for certain terms. Does their app name include it? Is it prominent in their subtitle? Understanding their strategy helps you formulate your own. I had a client, a niche productivity app, who saw a competitor suddenly rank #1 for “focus timer with haptic feedback.” We immediately realized our app had that feature but we hadn’t highlighted it. A quick subtitle update moved us into the top 5 for that term within weeks.

Common Mistake: Only looking at direct competitors. Sometimes, apps in tangential categories (e.g., a journaling app for a meditation app) can reveal unexpected keyword opportunities that your direct rivals aren’t even considering.

Expected Outcome: A clear understanding of your competitors’ top-performing keywords and potential gaps in your own keyword strategy. You’ll identify at least 5-10 high-value keywords to add to your target list based on competitor success.

3.2 Cross-Referencing Keywords for Overlap and Gaps

1. Still in “Keyword Spy,” use the “Compare Apps” feature (usually a button or tab near the top).
2. Select your app and up to two competitors for a direct keyword comparison.
3. The comparison view highlights keywords where multiple apps rank, or where one app ranks significantly higher than others.
4. Look for keywords where your competitors rank well, but you don’t rank at all, or rank very poorly. These are your immediate targets for optimization.
5. Conversely, identify keywords where you rank strongly and your competitors don’t. These are your unique selling propositions and terms to double down on.

Pro Tip: Don’t forget about the “Keywords Your App Lost” report. It’s brutal but necessary. If you were ranking for a term and suddenly dropped, it’s a red flag. Investigate whether a competitor optimized, or if an algorithm change impacted your listing. This report is under “Keyword Rankings” within “App Intelligence.”

Common Mistake: Overlooking the strategic value of identifying keywords where your competitors don’t rank. These can be your blue ocean terms, allowing you to dominate a specific niche without heavy competition.

Expected Outcome: A refined list of target keywords, categorized by their potential impact and competitive landscape, giving you a strategic advantage.

Step 4: Optimizing Your App Listing with Sensor Tower Insights

Keyword research is only half the battle. You need to actually apply those keywords effectively to your app’s listing. Sensor Tower helps ensure your app’s metadata and creative assets are conversion-optimized, not just discoverability-optimized.

4.1 Integrating Keywords into Metadata (iOS & Android)

1. Based on your research in Steps 2 and 3, you should now have a prioritized list of 15-20 target keywords.
2. For iOS, these keywords go into your App Name (primary keyword, 30 chars), Subtitle (secondary keywords, 30 chars), and the hidden Keyword Field (up to 100 chars, comma-separated). Sensor Tower’s “App Store Optimization” module (under “App Intelligence”) has a “Keyword Optimization” tool that helps you analyze keyword density and coverage for your current listing. Use it.
3. For Android, your App Title (primary keyword, 30 chars) and Short Description (secondary keywords, 80 chars) are crucial. The Full Description (4000 chars) is where you’ll naturally weave in the remaining keywords, ensuring readability. Sensor Tower provides a “Description Analysis” feature that highlights keyword usage.
4. Always write for humans first, then optimize for algorithms. Keyword stuffing makes your app look spammy and can hurt conversion.

Pro Tip: Don’t change all your keywords at once. A/B test your changes, especially for the App Name and Subtitle on iOS. Monitor the impact on impressions and conversion rates using Sensor Tower’s “Performance” metrics. I always advise clients to make incremental changes and track for at least 2-3 weeks before making another major adjustment. According to a Statista report from 2024, the global ASO market is projected to reach over $10 billion by 2027, underscoring the fierce competition and the need for data-driven iteration.

Common Mistake: Over-optimizing the keyword field on iOS. Don’t repeat keywords; it wastes space. Don’t use competitor names (unless you want to get rejected). Focus on unique, relevant terms.

Expected Outcome: An updated app listing that strategically incorporates your target keywords, improving both discoverability and relevance for potential users.

4.2 A/B Testing Creative Assets with Creative Insights

Your app icon, screenshots, and preview videos are just as important as your keywords. They are your first impression, and they drive conversion. Sensor Tower offers tools to test these visually.

1. Navigate to “Creative Insights” under “App Intelligence.”
2. Select your app and the specific creative asset you wish to test (e.g., “Icon,” “Screenshots,” “App Preview Video”).
3. Sensor Tower allows you to upload different versions of your assets and run A/B tests against a control group or against each other. You’ll define your target audience and the duration of the test.
4. Monitor metrics like Tap-Through Rate (TTR) and Conversion Rate (CVR) for each variant. Sensor Tower will provide statistical significance for the winning variant.

Pro Tip: Focus your screenshot strategy. The first 1-3 screenshots are the most critical, especially on iOS, as they’re visible without scrolling. Use these to highlight your app’s core value proposition and best features. For a recent gaming app launch, we tested five different sets of screenshots. The set that highlighted gameplay footage over UI elements saw a 22% increase in install conversion. Always test what you think is “obvious.”

Common Mistake: Using generic screenshots or icons. Your creatives need to be compelling, unique, and clearly communicate your app’s purpose and benefits. Avoid stock photos or overly cluttered designs. Think about what makes users stop scrolling.

Expected Outcome: Data-backed decisions on which creative assets perform best, leading to higher tap-through rates and improved conversion from app store visitors to actual installs.

Step 5: Ongoing Monitoring and Iteration

ASO is not a set-it-and-forget-it strategy. The app stores are dynamic environments, with new apps launching daily and algorithms constantly evolving. Continuous monitoring and iteration are essential for sustained success.

5.1 Tracking Keyword Performance and Category Rankings

1. Return to “Keyword Rankings” under “App Intelligence.”
2. Monitor your app’s rank for all your target keywords daily or weekly. Look for significant drops or gains.
3. Use the “Keyword Planner” to track specific keyword sets you are targeting and see their performance over time.
4. Also, keep an eye on your “Category Rankings” to understand your overall visibility within your niche.

Pro Tip: Set up alerts within Sensor Tower for significant changes. For example, an alert if your app drops out of the top 10 for your highest-volume keyword, or if a competitor suddenly enters the top 5 for a term you dominate. This proactive approach allows for rapid response. I’ve seen clients lose significant market share because they weren’t monitoring keyword drops quickly enough.

Common Mistake: Only checking rankings sporadically. App store algorithms can shift, and competitor activity can impact your visibility quickly. Consistent monitoring is key to maintaining your edge.

Expected Outcome: A real-time understanding of your app’s performance in search results and categories, enabling timely adjustments to your ASO strategy.

5.2 Analyzing Review Sentiment and User Feedback

1. Within “App Intelligence,” navigate to “Reviews.”
2. Sensor Tower provides sentiment analysis, breaking down reviews into positive, negative, and neutral, often highlighting common themes or keywords mentioned by users.
3. Pay close attention to negative reviews. They often pinpoint bugs, missing features, or poor user experience. Addressing these issues not only improves your app but also signals to the app stores that you’re actively maintaining it, which can positively impact rankings.
4. Filter reviews by “keyword” to see what users say about specific features or aspects of your app.

Pro Tip: Don’t just read reviews; respond to them. Especially negative ones. A thoughtful, prompt response can turn a negative experience into a neutral or even positive one, and shows potential users that you care. It also provides valuable qualitative data that no quantitative report can fully capture. It’s part of the broader marketing ecosystem that feeds into ASO.

Common Mistake: Ignoring reviews, especially negative ones. Reviews are a direct line to your user base. They provide invaluable feedback for product development and also influence conversion rates – users often check reviews before downloading.

Expected Outcome: Actionable insights from user feedback that can inform product updates, improve user satisfaction, and indirectly boost your ASO by fostering positive reviews and ratings.

Mastering ASO with a tool like Sensor Tower requires diligence, strategic thinking, and a commitment to continuous optimization. By following these steps, you won’t just be guessing at what works; you’ll be making data-driven decisions that propel your app to the top of the charts, ensuring your marketing efforts translate into tangible growth.

For more on ensuring your app’s long-term success, consider how to retain customers and grow revenue beyond initial acquisition. This holistic approach ensures discoverability translates into sustainable business growth. Additionally, understanding your app analytics is crucial for growth, providing the data needed to refine your ASO and overall marketing strategies effectively. Don’t forget that consistent organic growth is the only sustainable path for long-term success, which ASO significantly contributes to.
