How to use these statistics
Three principles for using these statistics in your own content:
- 1.Always cite the source and year. "AI search grew 527% (Previsible, 2025)" beats "AI search grew 527%." The citation signal is itself a +28% GEO strategy.
- 2.Place statistics in the first two sentences of a paragraph. Statistics placed early are 2.3× more likely to be cited than statistics buried mid-paragraph.
- 3.Use the four-part format. Number + unit + source + year. Each missing part reduces citation probability by 8–12%.
