App Store Optimization

Definition

An app store optimization agency improves how a mobile app ranks and converts inside the Apple App Store and Google Play: keywords, titles, screenshots, ratings, and store page experiments. App publishers hire them because store search remains the largest source of organic installs, and small ranking moves change install volume materially.

How they make money

Monthly retainers dominate, typically 2,000 to 10,000 dollars depending on how many apps, markets, and languages are in scope and whether the agency also produces the creative assets, screenshots, icons, and preview videos, that store conversion depends on. One-time audits, a keyword and conversion teardown with a prioritized roadmap, are a common entry product priced from the low thousands.

Many ASO agencies also manage Apple Search Ads and Google App Campaigns, billed the usual media way, as a percentage of spend or a flat management fee. That pairing is natural, paid and organic store performance feed each other, but keep the reporting separated so organic gains are not quietly claimed by paid, or vice versa. Localization is often priced per market. Pure performance pricing, per ranking or per install, is rare among credible firms because the stores' algorithms and editorial decisions sit outside anyone's control.

What good ones have in common

Two-store fluency. Apple and Google index different fields, weigh signals differently, and offer different testing tools. A strong agency explains those differences unprompted and runs distinct playbooks for each store.

Creative testing as a core service. Screenshots and icons usually move installs more than keywords. Good firms run structured experiments through the stores' native testing tools and iterate on a calendar, not on inspiration.

Keyword work tied to conversion, not vanity rankings. Ranking for a high-volume term that never converts is decoration. Credible reporting connects keyword movement to impressions, store page conversion rate, and installs.

Ratings strategy inside the rules. They engineer compliant review prompts, timed to moments of user satisfaction, and manage responses. They never buy reviews or incentivize ratings, which the stores punish severely.

Localization depth. Store search is local. Agencies that research keywords natively per market, rather than machine-translating the US listing, unlock installs that most publishers leave on the table.

Integration with your paid UA. Store conversion rate affects every paid install's cost. Strong firms coordinate with user acquisition teams and use custom product pages to match ad traffic to tailored store pages.

Red flags

Guaranteed rankings or top chart placement. Nobody controls store algorithms or editorial features. Guarantees signal either fantasy pricing or manipulation tactics that trigger store penalties.

Incentivized installs or review schemes. Burst campaigns of paid-for installs and purchased reviews can briefly move rankings and then get apps demoted or removed. The agency's risk is losing a client. Yours is losing the app.

Keyword-only reporting. A report that lists ranking positions but never shows store impressions, conversion rate, or installs is measuring activity, not outcomes. The stores provide those metrics; demand them.

One optimization, then a monthly invoice. ASO decays: competitors move, algorithms shift, seasonal search changes. If the deliverables after month one are vague monitoring, you are paying a retainer for a completed project.

Silence about your app's actual quality. Retention, crashes, and ratings feed rankings. An honest agency will say when the product, not the store page, is the ceiling. One that never mentions it is optimizing a symptom.

How the category is changing

The stores themselves are in flux. Apple and Google keep expanding AI-driven discovery, summarized reviews, and personalized store surfaces, which makes rankings less uniform across users and pushes agencies toward conversion assets and metadata that perform across contexts rather than chasing a single keyword position. Custom product pages and store listing experiments have matured into the center of the craft, effectively bringing landing page optimization discipline into the app stores.

Regulation is opening cracks in the duopoly. Rules in Europe and court decisions in the US have forced tolerance of alternative app stores, third-party payments, and web distribution, and while US install volume still lives overwhelmingly in the two big stores, sophisticated publishers now think about presence beyond them. Meanwhile AI tooling has compressed the effort of metadata drafting and screenshot variations, so agencies differentiate on experiment design, localization judgment, and their integration with paid user acquisition rather than on production labor.

Frequently asked questions

How much does an ASO agency cost?

Typical retainers run 2,000 to 10,000 dollars monthly depending on apps, markets, and whether creative production is included. One-time audits start in the low thousands and are a sensible first purchase.

How long does app store optimization take to work?

Metadata changes register within days, but meaningful movement in impressions and installs typically takes two to three months of iteration and testing. Competitive categories take longer. Treat it as a program, not a fix.

What matters more, keywords or screenshots?

For most apps, conversion assets, screenshots, icon, and preview video, move installs more than keyword tweaks, because they affect every visitor from every source. The best programs work both, but creative testing usually pays first.

Is ASO different for the App Store and Google Play?

Substantially. They index different metadata fields, weigh engagement signals differently, and offer different native testing tools. A serious agency maintains separate keyword and testing strategies per store.

Can an agency get my app featured by Apple or Google?

No one can promise featuring; it is editorial. Agencies can improve your odds by preparing feature-worthy assets, following each store's submission channels, and timing pitches to seasonal moments, but a guarantee is a fiction.

Do I still need ASO if I run paid install campaigns?

More than ever. Every paid click lands on your store page, so its conversion rate sets your cost per install. Store optimization typically lowers paid acquisition costs while growing the organic installs paid activity stimulates.

ASO specialists are among the narrowest of marketing agencies, tuned to two storefronts owned by two companies, and studios that build apps through staffing agencies and dev shops usually call them right before launch day.
