How to use this tool
1
Enter your current traffic numbers
Monthly organic visits and value per visit are the most important inputs. Check Google Analytics or Search Console for organic visits. Revenue ÷ organic visits = value per visit.
2
Set realistic growth assumptions
The default AI search growth rate (85% annually) is a mid-range estimate. Your industry matters — tech and marketing niches are seeing faster AI search adoption than, say, legal services.
3
Read the 3-year projection
The model shows relative traffic value from organic SEO vs AI-driven GEO over 36 months. At current AI growth rates, most niches will see a crossover point within 2 years.
4
Use the recommendation as a starting allocation
The verdict isn’t “GEO instead of SEO” — it’s about finding the right ratio given your current position and projected market shift. Most sites should be moving to at least 30-40% GEO investment.
5
Revisit quarterly as data evolves
AI search growth is accelerating. Run this calculator quarterly with updated AI visit numbers from your analytics to see if the crossover point is arriving sooner than projected.
