ASO Ranking Factors

The app name is the strongest textual ranking factor in the App Store. Apple allows up to 30 characters. Use them fully, but naturally:

• Brand name + main keyword: Combine your brand name with the most important search term you want to rank for.
• Avoid keyword stuffing: "Meditation Sleep Relaxation Yoga" looks unprofessional and lowers conversion.
• Readability over algorithm: The title must be understandable and memorable for users.

Example: "Calm: Meditation & Sleep" instead of just "Calm".

The subtitle appears below the app name and also has up to 30 characters. It's a relevant ranking factor and, at the same time, your second advertising line:

• Place secondary keywords: Use terms that no longer fit in the title.
• Communicate the benefit: Explain in one sentence what the app solves.
• No repetition: Words already used in the title add little extra value in the subtitle.

In App Store Connect you can store up to 100 characters of keywords. This field is invisible to users but very important for the algorithm:

• Separate terms with commas: "meditation,sleep,relaxation" – spaces are optional, but commas are mandatory.
• No repetitions: Words from the title and subtitle don't need to be repeated here.
• Singular and plural: Apple often recognizes both forms automatically, but it's safer to cover both variants deliberately.
• No other brands' names: This can lead to rejections.
• Localize the field: Translate keywords for every store you serve.

The description is primarily a conversion factor, not the strongest ranking factor. You have up to 4,000 characters available. Still, you should work keywords in deliberately and naturally, since they can be indexed by Apple:

• The first three lines are crucial: Users initially see only the teaser text.
• Structure with paragraphs and bullet points: Better readability increases dwell time.
• Call to action at the end: "Download the app now for free."

Screenshots are the most important visual conversion factor. Users scroll quickly – your first 1–3 screenshots decide whether someone installs:

• Use text overlays: Explain the concrete benefit on each screenshot in 3–5 words.
• Place your main keyword visibly: When users search for "sleep app" and read that word on a screenshot, perceived relevance increases.
• Test different variants: A/B tests via App Store Connect Product Page Optimization.
• App preview video: A short autoplay video on the detail page can significantly boost conversion.

Star ratings and the number of reviews influence both ranking and conversion:

• Average rating: Apps with 4.5 stars or higher are installed more often.
• Number of ratings: A high count signals trust and can indirectly strengthen ranking.
• Ask regularly: Prompt satisfied users for a rating via in-app prompts – ideally after a positive experience.
• Respond to reviews: Especially at 1–3 stars, responsiveness demonstrates quality.

Apple rewards well-maintained apps. Regular updates with release notes signal that the app is current and cared for:

• Update at least every 4–8 weeks: Even minor bug fixes count.
• Minimize crash rate: High crash rates negatively impact visibility.
• Watch app size: Large apps download worse over cellular connections.

Apple measures how many people who see your app actually install it after an impression. A high conversion rate confirms relevance:

• Optimize icon, screenshots and title: These are the click drivers.
• Test pricing: Freemium, paid or subscription – the right model influences installs.
• Fast-loading detail page: Fewer drop-offs from long wait times.

The German store, US store, UK store etc. are separate from each other. Full localization significantly increases your reach:

• Translate title, subtitle and keywords: Not just the description.
• Localize screenshots: Text in images should be in the local language.
• Mind cultural differences: What works in Germany doesn't necessarily land the same way in the US.

• In-app purchase names: Indexed by Apple and can provide additional keywords.
• Developer name: The developer's name can, in rare cases, carry minor relevance too.
• Web referrals & backlinks: External links to the App Store page can increase visibility outside the store.
• Feature requests & Apple editorial: A recommendation in the "Today" tab or as App of the Week brings enormous reach.
