What These Statistics Mean for Marketers

The data paints a clear picture: AI search is not an emerging trend — it is an established channel with massive reach and measurable business impact. The key takeaways for marketing teams:

AI search is too large to ignore. With 800+ million users and 30% query share, not optimizing for AI search is equivalent to ignoring mobile search a decade ago.

Citations are concentrated. The top domains capture a disproportionate share of AI citations. Early movers in GEO gain compounding advantages as AI engines learn to trust their content.

Technical optimization has outsized impact. Schema markup, llms.txt files, and content structure changes produce measurable citation improvements — and these are one-time investments.

The ROI is strong and growing. At 340% average ROI, GEO investment compares favorably to most marketing channels. As AI search volume continues to grow, the returns will increase.

Action beats analysis. The average GEO score of 38/100 across all analyzed domains means most competitors have not yet optimized. The window for first-mover advantage is still open — but closing.
