What is GEO?

Generative Engine Optimization (GEO) is the practice of optimizing your content, brand, and online presence to be cited by AI search engines like ChatGPT, Perplexity, Claude, and Google's AI Overviews.

When someone asks ChatGPT "What's the best project management tool for startups?", the answer doesn't come from a search ranking algorithm. It comes from the LLM's training data and real-time web access. GEO is about getting your brand into those answers.

"SEO is about ranking on page one. GEO is about being mentioned in the answer. It's a fundamentally different game."
— Greg Isenberg

The Search Paradigm Shift

Traditional Search (Google)

  • 1. User types query
  • 2. Google shows 10 blue links
  • 3. User clicks through to sites
  • 4. User compares and decides

AI Search (ChatGPT, Perplexity)

  • 1. User asks a question
  • 2. AI synthesizes an answer
  • 3. Mentions specific brands/tools
  • 4. User may never visit your site

GEO vs Traditional SEO

GEO isn't replacing SEO—it's a parallel channel. But the strategies are fundamentally different.

Dimension Traditional SEO GEO
Goal Rank on page 1 Get mentioned in the answer
Time to Results 3-6 months 24-48 hours
Primary Signal Backlinks, domain authority Mentions on cited sources
Content Strategy Keyword-optimized pages Natural mentions in discussions
Key Platforms Your website Reddit, forums, publications
User Journey Click to your site May never visit your site
Visitor Value 1x baseline 4.4x higher value

Why LLM Visitors Are Worth 4.4x More

When an LLM mentions your brand, it's already done the comparison work. The user arrives with context and intent. They're not comparing 10 options—they've been told you're the answer to their specific problem. This pre-qualification drives higher conversion rates.

Where LLMs Get Their Answers

LLMs don't crawl the web like Google. They rely on training data plus real-time retrieval from trusted sources. Understanding where they look is the key to GEO strategy.

Reddit

High Priority

The #1 source for LLM answers about products, tools, and recommendations. Real discussions carry weight because they're hard to fake.

LLMs heavily cite r/SaaS, r/Entrepreneur, r/startups, r/webdev, and niche subreddits.

F

Forbes, Inc, Business Insider

Authority

High-authority publications are trusted by LLMs. Getting mentioned in a "Top 10" list on Forbes carries significant GEO weight.

Contributor programs make this accessible. Many accept guest posts or paid placements.

W

Wikipedia

High Authority

The gold standard for factual information. Having a Wikipedia page (or being cited on one) is extremely valuable for GEO.

Must meet notability requirements. PR coverage helps establish notability.

Niche Industry Publications

Targeted

Industry-specific publications (SaaS blogs, tech publications, vertical media) are heavily cited for domain-specific queries.

Examples: TechCrunch, Product Hunt, Indie Hackers, industry newsletters.

Forums & Communities

Organic

Hacker News, Stack Overflow, Quora, and specialized forums. Real users recommending real solutions.

Authentic recommendations from community members carry more weight than marketing copy.

The Surface Area Strategy

Greg Isenberg calls this "increasing your surface area"—getting your brand mentioned across as many LLM-cited sources as possible. The more places you appear, the more likely you are to be mentioned.

The Surface Area Formula

GEO Visibility = Mentions × Source Authority × Relevance

You need mentions on multiple authoritative sources that are relevant to your target queries. A single mention on Forbes isn't enough—you need a pattern across Reddit, publications, and communities.

Surface Area Tactics

1

Seed Reddit Discussions

Participate authentically in relevant subreddits. When someone asks "What tool do you use for X?", your genuine recommendation gets indexed. Don't spam—contribute value.

2

Get Featured in Listicles

"Best tools for X" articles are heavily cited by LLMs. Reach out to publications that write these. Offer a free account, affiliate partnership, or simply ask to be included.

3

Answer Quora Questions

Quora ranks well and is cited by LLMs. Find questions related to your product category and provide detailed, helpful answers that naturally mention your solution.

4

Publish Comparison Content

Create "[Your Product] vs [Competitor]" pages. When users ask LLMs to compare tools, these pages get cited. Be honest about trade-offs—LLMs prefer balanced content.

5

Podcast Guest Appearances

Podcast transcripts get indexed. When you mention your product on a podcast, that transcript becomes a citable source. Aim for niche podcasts in your industry.

The Speed Advantage: 24-48 Hours vs Months

Traditional SEO takes months to show results. GEO can work in 24-48 hours. This is the biggest tactical advantage of GEO for startups.

Why GEO Works Faster

Real-time Web Access

ChatGPT, Perplexity, and Claude can access live web data. A Reddit post from today can be cited in an answer tomorrow.

No Ranking Algorithm

You don't need to build domain authority or earn backlinks over time. If you're mentioned on a trusted source, you can be cited immediately.

Recency Matters

LLMs often prefer recent sources. A discussion from this week may be cited over a blog post from 2022. This levels the playing field for new entrants.

"With GEO, you can launch a product today, seed some Reddit discussions, get mentioned in a few publications, and be cited by ChatGPT within 48 hours. That's the window from zero to AI visibility."
— Greg Isenberg

Traditional SEO Timeline

  • Week 1 Publish content
  • Month 1 Google indexes pages
  • Month 3 Build backlinks
  • Month 6 Start ranking
  • Month 12 Meaningful traffic

GEO Timeline

  • Hour 1 Post on Reddit
  • Hour 12 Discussion gets traction
  • Hour 24 LLMs can access it
  • Hour 48 Cited in AI answers
  • Week 1 Referral traffic begins

What to Optimize For

GEO isn't about gaming an algorithm—it's about being the genuine answer to real questions. Here's what to focus on:

1 Query-Specific Mentions

Identify the exact questions your target users ask LLMs. Then get your brand mentioned in content that answers those specific queries.

Example query: "What's the best tool for extracting YouTube transcripts?"
Target content: Reddit discussion, "Top 10 Transcript Tools" article, Quora answer

2 Unique Value Proposition

LLMs prefer specific, differentiated recommendations. Generic tools get mentioned less than tools with clear differentiation.

Weak: "We're a project management tool"
Strong: "We're the only PM tool with async video updates built in"

3 Social Proof in Context

LLMs cite sources that include evidence. "I switched from X to Y and saved 10 hours/week" is more citable than "Y is great."

Encourage: Specific testimonials, case study posts, before/after comparisons

4 Recency and Freshness

LLMs often prefer recent content. Keep seeding new discussions and getting fresh mentions. A Reddit post from this month beats one from 2022.

Cadence: Monthly Reddit participation, quarterly publication outreach, weekly community engagement

Frequently Asked Questions

Should I stop doing SEO and focus only on GEO?

No. SEO and GEO are complementary channels. SEO still drives significant traffic, especially for transactional queries. GEO is an additional channel, not a replacement. The best strategy is to do both.

How do I know if my GEO efforts are working?

Ask LLMs about your product category and see if you get mentioned. Track referral traffic from AI sources (some analytics tools now identify ChatGPT/Perplexity referrals). Monitor brand mentions across Reddit and forums.

Is it okay to post about my own product on Reddit?

Yes, if done authentically. Reddit values genuine participation. Contribute to discussions, help people, and mention your product when relevant—not in every post. Building karma and credibility first helps.

Can I do GEO for a new product with no users?

Yes, and this is where GEO shines. New products can get AI visibility faster than SEO visibility. Focus on seeding discussions, getting early user testimonials on forums, and publishing comparison content.

How often do LLMs update their knowledge of websites?

LLMs with web access (ChatGPT with browsing, Perplexity) can access real-time data. Even base models get periodic updates. The recency advantage means fresh content on Reddit can be cited within 24-48 hours.
