Generative Engine Optimization, explained.

GEO is how B2B SaaS companies get cited by name in ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews. It is to AI search what SEO is to Google search — but the mechanics are different, and so is the playbook. Authority runs a productized GEO service called The Shortlist Method: a $1,490 audit and three retainer tiers, with results measured across all five engines weekly.

The five-step Shortlist Method.

1. 01

   Measure across five engines

   Run a fixed prompt set (category, comparison, problem-led, persona) against ChatGPT, Perplexity, Gemini, Claude, and AI Overviews. Score each on mention rate, rank, engine breadth, and content extractability.

2. 02

   Diagnose the gaps

   Three failure modes account for ~90% of low scores: (a) content not structured for AI extraction, (b) weak entity authority on G2/Reddit/podcasts, (c) zero coverage on the prompts buyers actually type.

3. 03

   Fix content for extractability

   Restructure top buyer-intent pages: direct-answer leads, FAQ schema, comparison tables, named-entity consistency. AI engines extract from structure, not prose.

4. 04

   Build authority surfaces

   AI engines cite sources their training and retrieval already trust. Earn mentions on G2, Capterra, Reddit threads, /r/SaaS, podcasts, and trade press. Citation rate compounds with surface area.

5. 05

   Re-measure weekly

   Same prompt set, every week. WoW deltas surface what's working before you wait a quarter to find out. The Shortlist Index publishes this for free across five categories.

Common questions.

• What is GEO (Generative Engine Optimization)?+

  GEO is the practice of getting a brand cited by name when AI engines (ChatGPT, Perplexity, Gemini, Claude, Google AI Overviews) answer buyer questions. It is to AI search what SEO is to Google search. The mechanics are different — AI engines synthesize answers from a small set of trusted sources rather than ranking ten blue links — so the playbook is different too.
• Who needs GEO for SaaS?+

  B2B SaaS companies between $1M and $10M ARR whose buyers research software via ChatGPT, Perplexity, or AI Overviews before opening a sales call. If your target customers ask 'best CRM for a 10-person team' or 'tools like Pipedrive but cheaper' inside an AI tool, GEO is how you become the answer.
• Is GEO different from SEO?+

  Yes. SEO optimizes for Google's ranked-link results. GEO optimizes for the synthesized answers AI engines generate. SEO best practices (clean content, schema, links) help GEO, but GEO adds three more layers: extractable content structure, named-entity authority on third-party sources, and direct coverage of the prompts buyers actually type into AI tools.
• Which AI engines should I optimize for?+

  The five that own >95% of B2B SaaS AI search traffic in 2026: ChatGPT (OpenAI), Perplexity (Sonar), Gemini (Google), Claude (Anthropic), and Google AI Overviews. Each weighs sources differently, so the goal is breadth — being cited across all five rather than dominating one.
• How long does GEO take to show results?+

  Initial citation rate improvements show within 30–60 days for content-extractability fixes. Authority-surface gains (G2 reviews, Reddit mentions, podcast coverage) typically take 90–180 days. The most reliable compounding is at 6–12 months of consistent execution.
• How is GEO measured?+

  By citation rate — the share of buyer-intent prompts where your brand is named in the AI response — and by rank within those answers (top-3 citations are worth 4× a #10 mention). Authority's free Shortlist Score returns both for any domain in 90 seconds.
• Can I do GEO myself?+

  Yes — if you have ~10 hours per week to run prompts, parse responses, restructure content, and build authority surfaces. The hard part is not the work, it's the consistency: most teams stop after the first measurement run because there's no obvious next step. The Shortlist Method gives you a ranked 90-day roadmap so you don't have to invent it.
• What does Authority do?+

  Authority runs a productized service called The Shortlist Method. We sell a $1,490 one-time audit (delivered in 5 business days) and three monthly retainer tiers ($2,490 Launch, $3,990 Growth, $6,490 Authority) that execute the audit's roadmap. We also publish The Shortlist Index — free public weekly rankings of which B2B SaaS companies AI engines actually recommend.
• Does Authority guarantee citations?+

  No. We guarantee process and measurement. Specifically: a measurable Shortlist Score lift on the prompts that matter to your buyers within 90 days of starting a retainer. If we don't move the score, the next month is free. We refuse to guarantee individual rankings because they depend on AI engine behavior outside any agency's control.
• How is Authority different from a regular SEO agency?+

  Three differences. (1) We measure across five AI engines, not just Google. (2) Our deliverables emphasize content extractability and entity authority, not link building or technical SEO. (3) We publish our methodology and our public Index — every claim we make is verifiable by anyone running the same prompts.
