Everything You Need to Know About App Store Optimization (ASO)
In a world flooded with mobile apps, simply launching an app is no longer enough. Whether you’ve built a game-changing health tracker or a quirky productivity tool, one question remains: how will people find it? That’s where App Store Optimization (ASO) comes into play.
At Substance Communication, we’ve worked with dozens of businesses and startups to increase their app visibility and downloads using ASO strategies. In this blog, we’ll break down everything you need to know about ASO from what it is to how to do it right.
What is App Store Optimization (ASO)?
App Store Optimization (ASO) is the process of improving the visibility and conversion rate of a mobile app within app stores like Apple’s App Store and Google Play. Just like Search Engine Optimization (SEO) helps your website rank on Google, ASO helps your app rank higher in app store search results. Better rankings mean more visibility, more downloads, and more revenue.
Why is ASO Important?
There are over 5 million apps available between Google Play and the App Store. ASO ensures your app doesn’t get lost in the noise. Here’s why it matters:
• 70% of app downloads come from search within app stores
• 65% of users download apps after searching
• Higher rankings = higher organic downloads
• It reduces user acquisition costs significantly
In short, ASO is one of the most cost-effective ways to drive growth for your mobile app.
Key Factors That Impact ASO
There are several elements that influence how your app ranks in search results and how likely a user is to download it. Let’s dive into the most critical ones:
1. App Title and Subtitle (iOS) / Short Description (Android)
Your app’s name is the most important ranking factor. It should include your brand and one or two relevant keywords (without stuffing). For example:
Before: TaskPro
After: TaskPro - To-Do List & Task Manager
The subtitle or short description further boosts visibility and should highlight your app’s core benefit.
2. Keywords (Especially on iOS)
Apple allows you to specify keywords in a dedicated field. Choose keywords based on:
• Relevance
• Search volume
• Competition
Tools like App Radar, Sensor Tower, or Keyword Tool can help you discover valuable keywords for your niche.
3. App Description
Your description is important for conversions (especially on Android where it also affects rankings). The first 2–3 lines should clearly communicate:
• What your app does
• Why it’s valuable
• What problem it solves
Use bullet points to list features and include a call to action (e.g., “Download now” or “Try it for free”).
4. App Icon
Humans are visual creatures. A unique, clean, and easily recognizable icon can drastically improve your click-through rate. Avoid clutter and ensure it looks good in various sizes.
5. Screenshots and App Preview Video
Visuals matter. Upload high-quality screenshots that show your app’s core functions, benefits, and design. Consider adding an explainer video for better engagement — this can increase installs by up to 35%.
6. Ratings and Reviews
Apps with better ratings naturally rank higher. Encourage satisfied users to leave reviews using in-app prompts but don’t overdo it. Address negative reviews by providing helpful support and bug fixes quickly.
7. App Updates
Regular updates signal that your app is well-maintained and continually improving. This helps with both user trust and app store visibility. Highlight what's new in each update in a user-friendly way.
ASO vs. SEO: What’s the Difference?
While both ASO and SEO focus on discoverability, they operate in different ecosystems. Here's a quick comparison:
| Factor | SEO | ASO |
|---|---|---|
| Platform | Google, Bing, Etc. | App Store, Google Play Store |
| Primary Elements | Keywords, Content, Backlinks | Title, Keywords, Ratings |
| Objective | Website Traffic | App Install |
| Conversion | Clicks or Leads | Install or Opens |
