SEO Is Not Dead. It Just Got an AI Upgrade
Welcome to the Era of GEO
If your digital strategy is still chasing blue links on page one of Google, you are competing for a shrinking slice of the pie.
In 2026, over 60 per cent of search queries are answered directly by generative AI tools like ChatGPT, Perplexity, and Google Gemini. Users get answers without ever clicking a website.
The real question is no longer how to rank number one.
The question now is how to get AI engines to cite your brand as the authority.
This shift is called Generative Engine Optimization, or GEO.
It is not about keyword stuffing anymore. It is about:
- brand citability
- entity authority
- structured data
