App Store Optimization

I start with keyword research, not screenshots or icons. Open App Store Connect and Google Play Console, type your core function into search and note the suggested queries. Then scrape the titles and subtitles of the top 10 competitors. For a habit-tracking app, I found that the word 'routine' appeared in four of the top five titles. I put 'Habit Tracker' in the title and 'Daily Routine Planner' in the subtitle. Within two weeks impressions increased by 35%.

Next, I move to visual assets. I design three screenshot sets and run an A/B test using Product Page Optimisation on iOS or Store Listing Experiments on Play. I test the first screenshot first because it carries the most weight. One client saw install rate jump from 8% to 14% by replacing a generic feature graphic with a screenshot showing the core workflow. I test one variable at a time – only after creative is stable do I test metadata changes.

After conversion is optimised, I tackle ratings and reviews. I implement a ratings prompt triggered after a user completes a meaningful action (finishing a session, hitting a streak). The same app went from a 4.2 to a 4.5 rating in two months. I respond to every review within 24 hours – Apple and Google both surface recent responses.

Finally, localization. I translate the full listing for each market, including the title if the local language uses a different script. For a meditation app targeting Japan, changing the title to katakana and adding local keywords improved conversion by 22%. If you are working with a [SEO agency](/seo-agency/) that also offers ASO, make sure they understand platform-specific fields. A [SaaS SEO](/saas-seo/) approach often overlaps because the product is an app, but the metadata rules are different. For larger organisations, an [enterprise SEO agency](/enterprise-seo-agency/) might have dedicated ASO resources.

I also keep an eye on competitors' updates. If a rival changes their subtitle or icon, I check if it coincides with a ranking jump. That tells me what the store algorithm is valuing right now. This is not a quarterly task – I check the top 10 every two weeks.

The biggest trap is treating ASO as a one-time setup. App store algorithms change – Apple introduced in-app events and started promoting them above generic results. A client whose app relied on keyword density in the title saw impressions drop 40% overnight. I now re-audit the listing every time Apple or Google releases a major ranking update.

Watch out for keyword stuffing in the title. Apple rejects apps that misuse the title for keywords – the title should be your brand name plus a short descriptor. Keep it under 30 characters. Use the subtitle for modifiers. Google Play is more lenient but still penalises spammy behaviour.

Another common mistake: ignoring negative reviews. A single one-star review can tank your rating if you have fewer than 50 reviews. I respond within 24 hours, offering a fix or acknowledging the issue. This often convinces the user to update the review. Google Play shows recent reviews prominently, so a negative one with no response hurts conversion.

Don't assume the same creative works across both stores. I tested the same screenshot set on iOS and Android – the install rate was 12% on iOS but only 7% on Play. Users on each platform expect different design languages. I now create separate assets for each store. Also, avoid testing too many variables at once. I've seen teams change the icon, screenshots, and subtitle simultaneously, then unable to attribute the 15% drop to any one change. Run one test per week and let it reach 95% statistical significance.

For niche verticals, the same principles apply but the competitor set is smaller. A [dental SEO](/dental-seo/) app targeting dentists should still research keywords, but the volume will be lower. For [real estate SEO](/real-estate-seo/) apps, location-based keywords in the subtitle matter. I treat each vertical as its own market; what works for a fitness app may fail for a business tool.

Finally, don't ignore the app icon. It is the first element a user sees. I once changed an icon to a simpler design expecting better appeal – conversion dropped 20% and I had to revert. Test icons separately, even if you are confident in the design.

I used to think ASO was just about keywords. I spent weeks researching keyword lists, stuffed the most popular ones into the metadata, and wondered why downloads were flat. The missing piece was creative. When I finally redesigned the screenshots to match the search intent – showing exactly what the user would get from the query – install rate doubled. I now spend as much time on visuals as on keywords.

Another mistake: I delayed localization. I launched a fitness app in ten countries with English metadata. In non-English markets, downloads were near zero. After translating into German and French, organic installs grew by 300% in those countries within a month. Localization is not just translation – it is adapting the value proposition. For Japan, I had to change the app description to emphasise community features because that resonated more than the core functionality I led with in English.

I also skipped preview videos for years, thinking they were too expensive to produce. Then I tested a 15-second video for a puzzle game client. Conversion on the video-enabled variant was 40% higher. I now mandate a preview video for every app I touch, even if it is a simple screen recording with a voiceover. The cost is repaid in installs within a week.

I once treated ASO and website SEO as separate disciplines. But user behaviour is similar – users type queries, expect relevant results, and decide based on visual cues. Principles from [digital marketing services](/digital-marketing-services/) like understanding intent and building trust apply equally. I now borrow from my SEO playbook: analyse search volume, match content to intent, test relentlessly. The only difference is the platform.

Finally, I used to think I could set and forget the metadata after launch. When Apple changed the algorithm to prioritise in-app events and subscriptions, my clients' ranking dropped because their listings did not mention subscriptions. I now review the store listing every month and adapt to any new ranking signals the stores introduce.
