How We Chose These Resources (methodology)

We evaluated resources against five criteria:

• Authority and independence (peer review, recognized outlet): 30%
• Practical applicability (steps, examples, templates): 25%
• Recency (2024–2025 updates): 20%
• Evidence quality (citations, disclosed methods): 15%
• Accessibility (free/low friction; clarity): 10%

We favored original/primary sources and publisher pages, limited vendor claims unless auditable, and avoided stale posts. Where concepts are emerging (for example, llms.txt), we label them experimental rather than prescriptive.

30-Day Action Plan to Use This Stack

• Days 1–3: Align on definitions. Read the foundational explainers from Search Engine Land, Walker Sands, and Built In. Draft your working definition of GEO, success metrics, and AI engines to prioritize.
• Days 4–7: Audit your AI visibility. Run a citation/sentiment spot-check across Gemini, ChatGPT, and Perplexity. Document which sources those answers cite for top prompts in your category.
• Days 8–14: Implement technical basics. Add or refine JSON-LD with @id-connected entities (Organization, Person, Product, Article) using Google’s docs and Backlinko’s schema guide. Validate with Google’s Rich Results Test. Create or review an experimental llms.txt following iFactory’s guidance.
• Days 15–20: Execute a focused play. Pick one TryProfound or Torro checklist and apply it to 3–5 high-potential pages. Structure AI-friendly summaries (TL;DR, bullet answers, FAQs) and tighten citations to authoritative sources.
• Days 21–25: Measure. Re-run AI answer checks. Track citations gained/lost, sentiment shifts, and any AI referral traffic. If you need a KPI framework for evaluation dimensions, see the “AI visibility” explainer above.
• Days 26–30: Institutionalize. Capture what worked into a repeatable workflow, set a quarterly review cadence, and plan one training slot (e.g., CXL’s cohort) for your team.

Notes, Caveats, and Next Steps

• Rich results vs AI citations: Implementing structured data increases clarity but does not guarantee inclusion in AI answers. Treat it as necessary but not sufficient.
• Evidence mix: Where vendor content appears, it’s because the methods are transparent and actionable; use your own testing to confirm fit.
• Research gaps: Neutral, data-heavy comparisons of AI citation rates across engines are still limited. The arXiv GEO-bench paper (2023/2024 use) offers methods you can adapt for internal testing.
