Astro-Cours
Online astrology academy: structured courses, premium tier, blog in three languages
Visit the site — Astro-Cours (opens in a new tab)
Context
An online academy for learning astrology in a clear, structured way: courses by level, articles, premium tier. Over 250 commits in nine months.
The challenge
Reconciling a progressive learning path, a high-output trilingual blog and careful SEO in each language — including tag pages.
What I did
next-intl routing with translated course, article and tag slugs, “smart link” components that resolve URLs in the right language, regular SEO audits (Screaming Frog, Ubersuggest, indexing) built into the development cycle.
Technical highlights
- Translated slugs for courses, articles and tags, with automatic link resolution
- Learning path by level with a premium tier
- SEO and accessibility audits documented and fixed continuously
- Documented GDPR compliance
