You want ChatGPT to recommend your brand when a prospect asks "best tool for [your category]". You want Perplexity to cite you in its answers. You want to exist in Google AI Overview.
Here's the concrete method, step by step, and when bringing in a GEO agency becomes more profitable than doing it yourself.
The four levers that flip LLM citations
No single lever suffices. Their combination makes the difference.
1. Domain authority
LLMs prefer to cite reputable sources. They rely on Google/Bing crawl underneath, and their source selection largely reflects the authority hierarchy of the indexed web.
What works: domain age, volume of quality backlinks, thematic consistency over time. An 8-year-old domain with 200 thematic editorial backlinks beats a 6-month-old domain with 2,000 directory backlinks.
2. Presence in sources LLMs already cite
Each niche has its LLM-preferred sources. For B2B SaaS: G2, Capterra, Reddit (r/SaaS, r/Entrepreneur), specialized third-party articles (TechCrunch, The Information). For marketing: Search Engine Journal, Marketing Brew, Twitter of a few experts.
What works: identify the 10-20 sources LLMs cite in your niche, and build an editorial presence there (guest posts, mentions by regular contributors, helpful Reddit threads). Mentionable exposes these sources directly in the dashboard.
3. Content structured in self-contained chunks
LLMs don't extract entire articles. They extract chunks (short paragraphs) that answer a sub-question. If your paragraphs don't make sense in isolation, they won't be extracted.
What works: 3-5 sentence paragraphs containing a complete answer (subject + figure + named source). H2s phrased as questions. Numbered lists for steps. Comparison tables for "best of" content.
4. External social signal
LLMs cross-reference their sources. A brand mentioned on Twitter, cited in podcasts, listed in sector directories generates signals LLMs integrate — directly (for those that crawl these sources) or indirectly (by increasing perceived authority).
What works: regular LinkedIn and Twitter presence, podcast appearances in niche shows, inclusion in lists and directories LLMs cite.
The concrete 90-day method
Month 1 — Audit and structure. Set up tracking on 30-50 business-critical prompts across at least 5 LLMs. Identify your current citation share. Analyze sources LLMs cite in your niche. Inventory the fan-out queries they run internally.
Month 2 — Produce GEO-friendly content. Produce 4-6 articles structured in self-contained chunks, targeting the identified fan-out queries. Also optimize 4-6 existing articles by restructuring their paragraphs. Invest in 1-2 presences on sources LLMs cite (guest article, helpful Reddit thread, mention by a regular contributor).
Month 3 — Measure and iterate. Measure citation share evolution per prompt and per LLM. Identify content starting to get cited. Double down on what works. Drop what doesn't move.
Why tracking is non-negotiable
Without measurement, you optimize blind. You produce content hoping it will be cited, without knowing if your efforts pay off.
A GEO tracking tool measures your daily appearance across 30-200 prompts × 7 LLMs. For a brand tracking 80 prompts on 7 LLMs, that's 560 measurements per day, roughly 17,000 per month. Impossible manually.
Mentionable is built for this work. Starting at $85/month, up to $325/month Agency plan for brands tracking hundreds of prompts.
Fan-out queries: the most strategic data
When a user types "best CRM for startups" in ChatGPT, the LLM doesn't just answer. It runs 5 to 15 sub-queries internally ("best CRM B2B 2026", "CRM Y combinator companies", "Pipedrive vs HubSpot startups", etc.) then synthesizes.
These sub-queries are fan-out queries. They're the most strategic data in GEO. Optimizing an article for a keyword ChatGPT never runs as a sub-query is wasted effort.
Identifying fan-out queries for your business prompts lets you target exactly what the LLM searches for internally. That's what tools like Mentionable expose directly.
When to bring in a GEO agency
Three signals indicate an agency becomes more profitable than doing it yourself:
- You track more than 50 prompts and nobody internally has 4-8 hours weekly to run the program.
- Your niche is highly competitive and fan-out analysis depth exceeds one person's capacity.
- You want to start in under 6 weeks with a proven methodology.
If none of these apply, doing it yourself with a tracking tool is almost always more efficient.
Finding an agency to accelerate
If you decide to bring in an agency, Mentionable maintains a hand-picked directory of GEO agencies and consultants. Every agency has been vetted on its citation methodology, tracking stack, and quantified client results. No commission, no paid placement.
