How is GEO different from SEO?

SEO optimizes for search engine rankings and click-through rates. GEO optimizes for AI understanding and recommendation. Key differences: GEO focuses on semantic clarity over keywords, narrative alignment over backlinks, and AI citation over page rankings.

Why does GEO matter for brands?

A growing number of consumers, especially younger generations, now use AI assistants instead of traditional search for product discovery. If your brand doesn't appear in AI recommendations, you're invisible to this expanding segment of your market.

GEO Score is a proprietary metric by Refractia that measures how well-optimized your brand is for AI discovery. It evaluates factors like AI visibility, sentiment, narrative alignment, and citation likelihood.
