App Store Optimization (ASO) Certification

The App Store Optimization (ASO) Certification is a free, test-based credential from Science of Apps. It certifies that you can grow app installs organically — keyword research and metadata, store creative, ratings and reviews, and store experiments, localisation and in-app events on the App Store and Google Play. Pass the 20-question, 30-minute test with 75% or more to become a Certified ASO Specialist (SOA-ASO). Every question is based on published standards and research — including App Store search (Apple App Store), Creating your product page (Apple App Store), Ratings, reviews and responses (Apple App Store) — and each answer is explained with its source.

Read the four skill domains on this page, study the free guides and sources linked to each, then take the 30-minute test online. There is no fee, course or sign-up. Score 75% or more and you get a Certified ASO Specialist certificate straight away — on screen, as a PDF and by email — with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: App Store search (Apple App Store); Creating your product page (Apple App Store); Ratings, reviews and responses (Apple App Store); Store listing best practices (Android Developers); Store listing experiments (Google Play Console Help); Localize app information (App Store Connect Help). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

App store optimization is the work of improving an app's visibility and conversion in the App Store and Google Play — choosing keywords and metadata, designing icons, screenshots and previews, managing ratings and reviews, and testing and localising store listings — to grow organic installs.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
