International SEO Certification

The International SEO Certification is a free 20-minute skill test from Science of Apps. It tests international SEO — URL structures, hreflang implementation, x-default, localisation vs translation, geotargeting signals and avoiding automatic redirects. Score 70% or more on its 20 questions to earn a verifiable International SEO certificate (SOA-ISEO). Every question is based on published standards and research — including Managing multi-regional and multilingual sites (Google Search Central), Localized versions of your pages (hreflang) (Google Search Central), Product data specification (Google Merchant Center Help) — and each answer is explained with its source.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a International SEO 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: Managing multi-regional and multilingual sites (Google Search Central); Localized versions of your pages (hreflang) (Google Search Central); Product data specification (Google Merchant Center Help); Think with Google (Google); What is SEO? (Moz); Keyword research guide (Ahrefs). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Structure and hreflang (URL structures, hreflang rules and x-default); Localisation and targeting (Localisation vs translation, Geotargeting signals and Redirects and language detection); International technical setup (Sitemaps with hreflang, CDNs and hosting and Currency and pricing); Market strategy and measurement (Market prioritisation, Local search engines and International analytics). Every question is an original scenario based on a published standard, official documentation or research, named under the question.

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.
