You've spent months building your app. It works great. Users love it. But downloads are flat because nobody can find it in the App Store.
App Store Optimization (ASO) is how you fix that. It's the process of optimizing your app's metadata — title, subtitle, keywords, description, and screenshots — so that the right people find your app when they search.
What Is ASO and Why Does It Matter?
ASO is essentially SEO for the App Store. Just like websites compete to rank on Google, apps compete to rank in App Store search results.
65%
of app downloads come directly from App Store search
If your app doesn't show up for the right keywords, you're invisible to the majority of potential users. The good news: unlike paid ads, ASO is free and the results compound over time.
The Key Elements of ASO
App Title (30 characters)
Your most important keyword real estate. Include your brand name and your primary keyword. For example: "Cal AI - Calorie Counter" tells both users and the algorithm what the app does.
Subtitle (30 characters)
Use this for your secondary keyword phrase. Don't repeat words from your title — the algorithm indexes both together. If your title says "Calorie Counter", your subtitle could be "Food Scanner & Meal Tracker".
Keyword Field (100 characters)
This hidden field is indexed by Apple's search algorithm. Use commas to separate keywords, don't use spaces after commas, and don't repeat words that are already in your title or subtitle. Every character counts.
Screenshots
While not indexed for search, screenshots dramatically affect conversion rates. The first three screenshots are visible without tapping — make them count. Show your app's core value proposition, not just features.
Description
Apple's algorithm doesn't index the description for search, but it matters for conversion. Lead with benefits, use bullet points for scanability, and include a clear call to action.
The Localization Advantage
Here's where most developers leave massive opportunity on the table: the App Store supports 40+ locales, and each one has its own title, subtitle, keywords, and description.
This means you have 40+ chances to rank for different keywords in different languages and regions. Even if you only speak English, you can optimize for English-speaking markets like the US, UK, Australia, and Canada — each with slightly different search patterns.
Managing 40+ locales in App Store Connect means clicking into each locale individually. MakePost lets you edit all locales from one screen, compare translations side by side, and push changes in one click.
Pricing as Part of ASO
Most ASO guides ignore pricing, but it's a critical factor in conversion. A $4.99 app in the US might be too expensive in India or Brazil, but Apple's default pricing tiers don't account for local purchasing power.

App Store territories with PPP-optimized pricing suggestions
Purchasing Power Parity (PPP) pricing adjusts your prices based on the economic conditions of each territory. MakePost uses World Bank GDP per Capita data to suggest optimal prices — so you can maximize revenue without pricing out users in lower-income markets.
Getting Started with ASO
ASO isn't a one-time task — it's an ongoing process. Here's your checklist:
Research keywords
Look at competitors, use Apple Search Ads for volume
Optimize title & subtitle
Include your highest-value keywords
Fill your keyword field
Use all 100 characters, no duplicates
Localize your metadata
Start with top 5 markets, then expand
Update your screenshots
Show benefits, not just features
Review and iterate
Check rankings monthly, adjust based on performance
