SEO ranks. AEO answers. GEO gets cited.
Three different jobs. Three different judges. Three different audience moments. Most agencies still only do the first one. We do all three.
SEO
Search Engine Optimization
Rank in the blue links.
What most people still call 'SEO' optimizes a page to rank in traditional Google search results. Necessary, mature, well-understood. But it only captures the user who actually clicks the blue links, which is a shrinking share of search behavior.
AEO
Answer Engine Optimization
Be the answer in the box at the top.
AEO is the practice of structuring content so AI Overviews, Google Assistant, Siri, and featured snippets pick YOUR content as the direct answer. The difference from SEO: SEO optimizes for RANKING, AEO optimizes for SELECTION.
GEO
Generative Engine Optimization
Get cited by ChatGPT, Claude, Gemini, Perplexity.
GEO is the brand-visibility layer for the generative AI era. When a user asks ChatGPT or Claude a question, you want your brand to be the one the AI mentions. Different signals matter: E-E-A-T authority, brand mention frequency across the open web, and content the model would actually want to cite.
The data behind the answers.
Based on multiple 2026 studies: Semrush analyzed 150,000+ LLM citations, 5W indexed 680M+ citations across five platforms, Lantern tracked 200M+ from the AI interfaces directly. The pattern is consistent.
Top sources cited by AI engines (2026)
Highest single source in 2026 studies
#1 source for ChatGPT specifically
Strong in product + tutorial queries
B2B authority + thought leadership
Long-tail Q&A queries
Top finance/personal-finance source
Concentrated citations in ChatGPT
Source: Semrush 2026 LLM Citation Analysis (150K+ citations). 5W AI Platform Citation Source Index 2026 (680M+ citations, Aug 2024-Apr 2026). Lantern AI Citation Content Visibility Report Feb 2026 (200M+ citations). Composite data, weighted average.
Each AI engine plays a different game.
You do not optimize for one engine. You build broad authority signals that satisfy all of them. But understanding each platform's bias is how you decide where to focus first.
ChatGPT
Pattern
Favors consensus and authority sources. Cites Wikipedia at 7.8% of all citations. Strong on Forbes, Business Insider, established media. Uses utm_source=chatgpt.com since June 2025 for attribution.
The Play
Get into Wikipedia. Get cited on established media. Brand mention frequency across the open web is the strongest predictor of ChatGPT citation (r=0.334-0.664 in studies).
Claude
Pattern
Prioritizes depth and structure. 30% more likely to cite bullet-pointed and well-formatted pages. Rewards clean semantic HTML and clear hierarchy.
The Play
Structure content with H2/H3 hierarchy. Use bulleted lists for key claims. Lead each section with a citable, direct answer before context.
Perplexity
Pattern
Recency-primary. Cites more sources per answer than any other engine. Heavy Reddit influence. Responds to structural changes in 2-7 days (fastest of any engine).
The Play
Publish often. Update existing content. Structure for Perplexity's "browsing" behavior by surfacing recent timestamps and fresh data points.
Google AI Overviews
Pattern
Hybrid: pulls from traditional SEO signals AND community sources. Wikipedia + YouTube + Reddit + Quora appear together in 13%/9%/6% of AIO responses respectively.
The Play
Strong technical SEO is the foundation. Add Speakable and FAQ schema. Build presence on Reddit and Quora in your topic clusters. Show up in YouTube.
Gemini
Pattern
Tightly tied to Google search behavior. Recent emphasis on multimodal sources (video, images). Picks Wikipedia frequently for foundational facts.
The Play
Same playbook as Google AI Overviews. Add video and visual content. Keep Wikipedia presence accurate and updated.
Win the direct-answer slot.
Six things that move the needle on Answer Engine Optimization in 2026.
Lead with the answer, then context
Every section should open with a direct, citable answer in the first 1-2 sentences. Save context, nuance, and supporting detail for AFTER the answer. This is how answer engines extract.
FAQPage schema is mandatory
The single most useful schema type for AEO. Mark up question-answer pairs. Make sure questions match how real users phrase queries (not how you would phrase them).
HowTo schema for procedural content
For step-by-step guides, How-To schema dramatically increases extraction probability. Each step gets its own structured entry.
Speakable schema for voice
Identifies content suitable for voice-assistant reading. Critical for Siri, Google Assistant, and Alexa. Mark up the 30-50 word answers most likely to be read aloud.
Concise factual blocks
Aim for 30-50 word answers to specific questions. LLMs prefer short, factual, citable blocks. Long paragraphs get summarized away.
Author bylines and credentials
E-E-A-T signals (Experience, Expertise, Authoritativeness, Trustworthiness) matter for selection. Real author names, real bios, real credentials, structured with Person schema.
Get cited by the generative engines.
Six things that move the needle on Generative Engine Optimization in 2026. Brand mention frequency is the moat.
Brand mention frequency is the moat
Get mentioned by name across the open web. Press, Reddit discussions, YouTube reviews, podcast appearances, GitHub README mentions. Brand-mention correlation with ChatGPT citation runs 0.334-0.664. Volume of mentions matters more than backlinks for GEO.
Deploy llms.txt at site root
The de facto standard for AI crawler discovery. A clean llms.txt at yourdomain.com/llms.txt tells AI engines exactly how to understand and cite your site. We did it for ourselves.
Wikipedia presence (if applicable)
Wikipedia is the #1 source ChatGPT cites and #2 across all engines. If your brand qualifies for a Wikipedia article (real notability, secondary-source coverage), it pays off massively in GEO.
Methodology corpus / public documentation
Publish your methodologies as citable public PDFs or pages. AI engines treat published methodology as authority. The federal acquisition world has been doing this for decades. Apply it to your commercial work.
Reddit + YouTube + LinkedIn presence
These three platforms account for the majority of social-signal citations in 2026. You do not need to dominate. You need to BE THERE with substantive contributions on the topics where you want to be cited.
Track citation traffic in GA4
ChatGPT now appends utm_source=chatgpt.com to citation links. Set up a custom GA4 channel matching chatgpt.com, perplexity.ai, claude.ai, gemini.google.com, copilot.microsoft.com. Watch the trend. AI traffic is a measurable channel now.

We do not sell mystery. We publish how we work. Every engagement runs the same stages, in the same order, with the same deliverables.
Week 1-2
Visibility Audit
Technical SEO baseline, AEO extraction audit, GEO citation snapshot. We measure where you stand on all three surfaces before touching anything.
Week 3-4
Foundation + AEO
Core Web Vitals tuning, schema deployment (FAQ, HowTo, Speakable, Organization, Person), llms.txt at root, content restructuring for answer extractability.
Week 5-6
GEO + Authority
E-E-A-T signaling, methodology publication, brand-mention strategy, citation tracking setup in GA4. Recommendations for content cadence and platform presence.
SEO, AEO, GEO: the common questions
SEO optimizes pages to RANK in traditional search. AEO optimizes content to be SELECTED as the direct answer in Google AI Overviews, voice search, and featured snippets. GEO optimizes brand presence to be CITED by generative AI engines like ChatGPT, Claude, Gemini, and Perplexity. They are three different jobs that share some technical foundations. SEO is mature. AEO is emerging fast. GEO is the newest discipline and the hardest to game.
