AI search is now real, measurable traffic — not a future trend. Plan for it.
Structure beats prose: AI engines prefer numbered takeaways, FAQs, and 'In short' blocks over narrative content.
Recency matters more for AI than for traditional Google. Refresh quarterly or you'll lose citation share.
Author credentials with Person schema raise citation rates measurably. Anonymous content underperforms.
Stats pages with cited sources are AI gold — they get quoted and linked at 2-3x the rate of equivalent how-tos.
Roughly 18-22% of US queries in mid-2026, up from under 5% in early 2024. The rate is much higher for informational and 'what is' queries (60%+) and much lower for transactional/commercial queries (under 6%).
When an AI Overview cites your URL, click-through to your site averages 2-4%. Lower than blue-link CTR, but the traffic that does click through tends to convert better — 2-3x the conversion rate of equivalent organic traffic for B2B query sets.
GEO is the set of practices that make your content easier for AI engines (ChatGPT, Perplexity, Gemini, Google AI Overviews) to ingest, understand, and cite. Tactics include: TL;DR blocks, FAQ schema, numbered takeaways, fresh updated dates, named author bylines with Person schema, and llms.txt files.
Yes if you publish long-form editorial or reference content you want AI engines to ingest. Adoption is still under 5% of business sites in 2026, so being early provides a meaningful signal — and the file is trivially easy to add.
No, but it changes the playbook. Traditional SEO (rankings, links, technical health) still drives the bulk of organic traffic. AI search adds a parallel discipline (GEO) focused on citation-friendly structure. Most leading 2026 programs invest in both.
