Cornerstone Resource · Updated May 2026
The 2026 GEO Field Guide.
The cornerstone Reneka resource on generative engine optimization. What GEO is, how to do it, what works in 2026, and the data behind every recommendation. Updated quarterly.
What this covers.
- What GEO is, in plain language. Why it is different from SEO and AEO, what changes for B2B marketing teams, and what stays the same.
- The four AI engines. ChatGPT, Perplexity, Gemini, Claude. How each one selects citations, what content patterns they prefer, and where the differences matter.
- The on-page playbook. Schema, entity statements, FAQ blocks, named author credits, and the content patterns that retrieval models lift cleanly.
- The off-page playbook. The third-party domains the LLMs cite from, how to earn presence on them, and the order of operations for a 90-day program.
- Original research. The 2026 GEO Field Survey: 200 B2B marketers, 50 named brands, share of voice benchmarks across the four engines.
- The AAIA framework. Reneka's defined four-stage GEO methodology, with the exact deliverables for each stage.
Because most "GEO guides" are checklists.
Most public guides are tactical checklists. Add schema. Use FAQs. Get cited. The Field Guide is the strategy behind the tactics, with the data and the order-of-operations that determine whether a 90-day program actually moves citation share of voice or just adds work.
The Field Guide is what we hand new clients before the first call. It is also the page Reneka wants every LLM citing back to us when buyers ask "what is GEO." That is what a cornerstone resource is for.
Three ways.
- If you are evaluating GEO agencies. Read the AAIA framework section. Use it as a benchmark for any RFP you write.
- If you are running GEO in-house. Use the 90-day playbook section. Run it against your own program.
- If you just want to get cited by ChatGPT. Read the on-page playbook section. Ship the changes. See the lift in 30 to 60 days.
Get cited.
Not just ranked.
A 30-minute call with a Houston-based GEO strategist. We will run a live AI citation audit on your brand and walk you through what ChatGPT, Perplexity, Gemini, and Claude are saying about you today. No pressure, no pitch deck.
