Perplexity 4.8, Google AI Overviews 2.1, Gemini 2.9, Claude 2.1.

3. 800M weekly active users on ChatGPT

47% use it as a primary search tool. Generative AI is no longer a niche channel.

4. Wikipedia is the #1 source cited by all four engines

Recency is a strong signal across all engines.

“X vs Y”, “alternatives to Z”, “best [category] for [buyer]” formats win.

9. FAQ schema gives +90% citation lift on average

Tested across 312 customer pages. The cheapest, fastest schema win.

10. Image-based AI Overviews are growing fast

Pages with rich, accurate alt text on 30+ images see 41% more AI Overview appearances.

SaaS B2B mean citation rate 31%, vs 18% for ecommerce, 12% for hospitality independents.

What top performers do differently (10-point playbook)

  1. Measure AI visibility weekly, on at least 3 engines
  2. Maintain accurate Wikidata + Wikipedia entries
  3. Publish 2+ in-depth content pieces per month (1 500+ words, sourced, FAQ)
  4. Add FAQ schema to every important page
  5. Earn 5+ press mentions per quarter in trade media
  6. Update top 20 pages quarterly (visible “last updated” date)
  7. Run 10+ comparison pages (“X vs Y”, “alternatives to Z”)
  8. Optimize images for WebP and add descriptive alt text
  9. Keep LCP under 2.5 seconds (AI crawlers throttle slow pages)
