This 7-step process needs to be implemented continuously, requiring measurement, testing and adjustment in each cycle for the app to achieve sustainable growth in increasingly fierce competition.

To optimize iOS app systematically, developers need to optimize based on real data, optimize according to conversion funnel, prioritize quick wins first, long-term later, and continuously optimize ASO.

Besides that, choosing the right supporting tools such as ASOLeap will help developers shorten deployment time to the maximum and achieve optimal efficiency with the most suitable budget.

1. 7 Steps To Optimize iOS App Systematically Need To Be Implemented?

There are 7 steps optimize iOS app systematically that need to be implemented: keyword research; optimize Title, Subtitle, Bundle ID; write Description, keyword field properly; design visual assets; optimize rating, review; improve retention, UX and track ASO periodically. 7 essential steps need to be implemented in order, from research, execution to measurement.

To implement 7 steps optimize iOS app effectively, below is a detailed guide for each step to improve visibility, increase installs and enhance user experience.

1.1. Step 1: Keyword Research

Keyword research and selecting iOS app keywords is the foundational step determining whether the app can reach the right target users or not. To choose iOS app keywords effectively, first build a seed keyword list, then analyze competitors' keywords. Next, evaluate, classify and select keywords. Finally, update the keyword list periodically.

Specifically, how to research and choose iOS App keywords step-by-step is as follows:

• First, build a seed keyword list: Based on the core features and unique selling points of the app, list about 20–30 keywords that accurately describe features, target users and app benefits. This keyword list is the raw material to find potential content niches.
• Then, analyze competitors' keywords: Analyze top 10 apps in the same niche on how they integrate keywords into Title, Subtitle and Keyword field. From this analysis, developers can quickly identify high search volume keywords and uncover market gaps that have not been exploited.
• Next, evaluate, classify and select keywords: Based on analyzed data, developers need to evaluate and classify keywords into 3 groups by competition level: high competition, medium and long-tail keywords. This classification helps build a realistic growth roadmap and allocate resources and budget properly. For example, high competition keywords are suitable for long-term growth, medium keywords for 3–6 month goals, and long-tail keywords are easiest to rank quickly.
• Finally, update the keyword list periodically: App keyword search trends constantly change by season. Therefore, every 4–6 weeks, the keyword list needs to be reviewed to ensure the ASO strategy aligns with market demand.

After having the target keyword set, the next step in optimize iOS app systematically is to focus on optimizing Title, Subtitle and Bundle ID.

1.2. Step 2: Optimize Title, Subtitle, Bundle ID

To optimize Title, Subtitle and Bundle ID, developers need to follow 3 core principles including: placing the keyword at the beginning of the Title, limiting the Title to 30 characters, inserting secondary keywords into the Subtitle and adding the main keyword into the Bundle ID. Optimizing based on these principles helps the App Store algorithm easily recognize and determine whether the app is relevant to a keyword.

Below are 3 core principles when optimizing Title, Subtitle and Bundle ID:

• Principle 1 - Place the keyword at the beginning of the Title, limit the Title to 30 characters: The optimal title structure is: [Brand Name] – [Main Keyword] or [Main Keyword]: [Brand Name]. The App Store algorithm often prioritizes ranking apps that have keywords appearing at the beginning of the title. In addition, unnecessary characters or filler words such as the, and,.. should be removed so that the title length stays within about 30 characters. Every word added to the title must have a strategy.
• Principle 2 - Insert secondary keywords into the Subtitle: Try to include 1–2 keywords with high search volume in the Subtitle because this is the field with the second highest ranking weight. Research by SplitMetrics (2023) shows that optimizing the Subtitle by inserting secondary keywords can improve click-through rate by 18% by providing more valuable information to users.
• Principle 3 - Add the main keyword into the Bundle ID: The main keyword should be added into the Bundle ID before submitting to the App Store. This factor helps the app index better in the initial stage.

Besides the publicly displayed information in Title, Subtitle and Bundle ID, developers need to continue optimizing detailed content in the Description and hidden data in the keyword field properly to boost ranking growth.

1.3. Step 3: Write Description, Keyword Field Properly

Writing Description and Keyword Field needs to be optimized according to ASO standards. In which, Description should focus on the first 170 characters, be written according to the conversion funnel, highlight benefits and avoid keyword stuffing. At the same time, the Keyword field should be optimized within 100 characters and must not use competitor brand names. Proper optimization of these factors both persuades users to install the app and helps the App Store algorithm expand keyword index coverage.

Specifically, principles for writing an attractive and ASO-standard Description are as follows:

Focus on the first 170 characters: Within the first 170 characters, highlight the benefits, unique value and a strong hook to encourage users to install immediately or continue reading.

Write according to the conversion funnel: You can follow a sample Description funnel structure such as: Start with the biggest benefit > then briefly present main features >> next provide social proof such as number of users, awards or outstanding reviews >> End with a strong CTA such as Install Now or Try Now.

Highlight benefits: Focus on benefits, meaning what the app helps users achieve instead of just listing features. For example, instead of writing Advanced photo editing tools, write Turn ordinary photos into stunning portraits in seconds.

Avoid keyword stuffing: Do not stuff keywords into the Description because the App Store does not use this section to directly rank keywords. Keyword stuffing makes content hard to read and may even cause the app to be rejected during review.

Principles for optimizing Keyword field according to ASO standards to help the App Store easily recognize:

Optimize within 100 characters: To optimize a high-quality 100-character field, do not repeat keywords already used in Title and Subtitle. Use commas between keywords instead of spaces. Especially prioritize single keywords rather than keyword phrases.

Must not use competitor brand names: Apple’s algorithm strictly penalizes the use of third-party trademarks in the Keyword field. If intentionally used, the app may be rejected when detected.

Besides writing a persuasive Description and optimizing Keyword Field, you also need to create strong visual signals such as designing icon, screenshots and preview video to drive users to the final decision.

1.4. Step 4 - Design Visual Assets

Designing visual assets includes icon, screenshots and preview video following professional principles that directly determine the app’s conversion rate. Specifically, icon design principles require simplicity, easy recognition, standout in the category . Screenshots should follow a storytelling funnel from Benefit hook, Features with real context, Social proof and CTA. Finally, preview video must be under 30 seconds, capture attention within the first 3 seconds and focus on benefits.

Specifically, principles for optimizing icon design to stand out and increase conversion are as follows:

• Simple, easy to recognize: Because icons are displayed at a very small size of 29x29 pixels, they need to be simple, easy to recognize but still convey the core value of the app. Design principles should avoid using text, limit excessive details and avoid complex colors.
• Stand out in the category: Use high-contrast colors to make the app stand out on the App Store search results screen. Ideally, research the color schemes of the top 10 competitors and choose the most effective palettes.

Principles for designing Screenshots according to storytelling funnel:

• Benefit hook - Screenshot 1: Screenshot 1 must convey the biggest benefit of the product and the most impressive result. A strong first screenshot will encourage users to swipe and view more.
• Features with real context - Screenshot 2 - 4: These screenshots introduce the main features of the app in real-life contexts. Additionally, include short captions of 5–7 words to highlight the benefit of each feature.
• Social proof and CTA - Final Screenshot: Show elements that build trust and drive install actions such as number of users, awards, outstanding ratings, highlighted reviews…

Principles for creating a preview video under 30 seconds:

• Preview video must be under 30 seconds and capture attention in the first 3 seconds: It is best to create a hook using impressive results or surprising features/benefits.
• Focus on benefits: Each scene of the video must convey a specific benefit to users. Additionally, optimize for silent viewing by delivering clear messages through visuals and subtitles.

Designing icon, screenshots and preview video plays a crucial role in users’ install decision. To increase trust and drive user action, developers must focus on optimizing rating, review and user feedback on the App Store.

1.5. Step 5 - Optimize Rating, Review

Developers need to implement SKStoreReviewAPI at the right time, filter sentiment, and respond to all reviews while handling negative reviews properly. These actions not only send positive signals to the App Store ranking algorithm but also help improve conversion rate efficiency.

Below are detailed techniques to optimize rating, review and user responses on the App Store effectively:

• Implement SKStoreReviewAPI at the right time: As soon as users experience value from the app, the rating request should be triggered immediately. Research from Apptentive (2023) shows that sending review requests right after a positive user action can increase the number of ratings by up to 5 times compared to random requests. This is also when users feel most satisfied, making them more likely to give a 5-star rating.
• Filter sentiment: Developers should use internal micro-surveys to redirect negative feedback to private support channels before publishing on the App Store. This significantly reduces negative reviews, helps maintain an average rating above 4.5, and reduces the risk of ranking drops.
• Respond to all user reviews: This action helps build a professional brand image. Responses also act as marketing content visible to thousands of potential users.
• Handle negative reviews properly: Never respond in a confrontational way to users with negative reviews. Instead, respond with empathy and provide clear, effective solutions. This can turn a dissatisfied user into a loyal customer, and even lead to improved ratings after the issue is resolved. 

After optimizing rating, review and user feedback, the next step is to improve user experience, retention and category ranking to ensure sustainable growth.

1.6. Step 6 - Improve Retention And UX

Developers should optimize retention by improving behavioral signals such as session length and Retention rate. Improving these signals creates a growth loop for the app, meaning better UX helps retain users longer, which in turn sends positive signals to the App Store algorithm to improve rankings.

Specifically, how to optimize user experience, retention and category ranking by maintaining a strong growth loop is as follows:

• Session length: Implement personalization mechanisms and fix issues based on patterns from real user reviews.
• Retention rate: Optimize onboarding and reduce crash rate to below 1% based on Apple benchmarks.

The market constantly changes, so alongside optimizing UX and metadata to improve app quality, developers must have a periodic tracking system to make timely adjustments when necessary.

1.7. Step 7 - Track ASO Periodically

To track and update ASO periodically, developers need to build clear KPIs, schedule regular metadata reviews and implement A/B testing. Especially, update metadata after A/B testing and monitor changes in the App Store algorithm. Optimize iOS App requires continuous tracking, measurement and updates to adjust strategies, thereby driving sustainable and effective install growth.

ASO tasks that need to be tracked and updated periodically include:

• Build clear KPIs: Developers need to define specific KPIs for metrics such as keyword ranking, organic conversion rate of the product page, organic installs by week and month, average rating and number of new reviews, crash rate and Day 7 retention. After defining KPIs and implementing Optimize iOS App, these metrics should be measured weekly.
• Schedule periodic metadata reviews: Every 4–6 weeks, review and evaluate all metadata including title, subtitle, keyword field and screenshots.
• Implement A/B testing: Use Apple’s Product Page Optimization feature to test screenshots, icons and preview videos. In each test, only change one variable. Run tests for at least 2 weeks to gather sufficient data before making adjustments.
• Update metadata after A/B testing: After identifying the winning version, update metadata immediately and record the results. Then continue the next testing cycle. This process should be continuous to improve CVR and drive installs.
• Monitor changes in the App Store algorithm: Apple’s ranking algorithm changes periodically. Therefore, developers need to closely monitor and detect these changes early to make timely adjustments and avoid negative impacts on rankings.

The 7 steps to optimize iOS app must be implemented based on strategic principles to achieve the desired effectiveness. Below are several principles that developers need to keep in mind.

2. How to Optimize iOS App Properly?

Optimize iOS app properly needs to follow 4 strategic principles: optimize based on real data, optimize according to conversion funnel, prioritize quick wins first then long-term, and continuous ASO optimization. The steps to Optimize iOS App in Part 1, when implemented properly according to these 4 strategic principles, ensure consistency, effectiveness, and sustainability of the campaign.

4 operational principles for optimize iOS app properly are as follows:

Principle 1 - Optimize based on real data: Do not arbitrarily change metadata, visual assets, or keyword strategy based on intuition. All changes must be based on real data from App Store Connect, A/B testing results, and keyword tracking.

Principle 2 - Optimize according to conversion funnel: The entire Optimize iOS App process must be synchronized and consistent across the conversion funnel. Execute from impression → Product Page View → Install → Retention. If optimizing each point separately, it will not generate the desired results. For example, high keyword ranking but low CVR will not generate organic installs, while high CVR but low retention will not create strong rankings.

Principle 3 - Prioritize quick wins first then long-term: The best strategy is to prioritize long-tail keywords first to quickly achieve high rankings and generate organic installs as initial momentum. Then leverage that strength to push more competitive keywords over time.

Principle 4 - Continuous ASO optimization: Optimize iOS App is a continuous marketing process. Do not only act when rankings drop significantly. Allocate time and resources weekly. Even small actions performed consistently can create significant long-term results.

Optimize iOS app includes many structured steps and strategic principles; so developers often rely on specialized iOS Services and supporting tools to save time and maximize implementation efficiency.
