Five years in SEO, two of them running live GEO campaigns for international clients, all pointed at the same outcome: getting brands cited and recommended inside AI-generated answers, not just ranked in a list of blue links. In August 2026, that practice became [Luminal](https://www.linkedin.com/company/luminal-geo/) - the agency behind this page. What it does and where is covered in full below. The work today runs across nine generative platforms and nine international markets, on sites built in eight languages from Vietnamese to Japanese.
