Three acronyms, three different battlegrounds, and at least four marketing blogs lying about the differences. I’ve watched founders pour 90 days into “GEO optimization” while their robots.txt blocked Perplexity. The acronym soup matters because the tactics for each one are different — and getting them confused costs you 3-6 months of work.
I’ve been running 500k.io for 90 days now. Site has DR 0, 32 articles, and full schema discipline. We’ve earned 0-2 weekly citations from probes against 30 queries. That’s the realistic baseline. Most of what’s written about AEO/GEO/SEO is enterprise-flavored or hype-flavored. Here’s the founder version.
If you’ve already read GEO 2026: how to get cited by ChatGPT and Perplexity, this article is the sister piece — same framework, broader scope.
What is each acronym, in one paragraph?
SEO (Search Engine Optimization) is the practice of structuring content so it ranks high on traditional search engine result pages — primarily Google’s blue links. AEO (Answer Engine Optimization) is structuring content so it appears in answer boxes — Google AI Overviews, Bing Copilot, featured snippets. GEO (Generative Engine Optimization) is structuring content so it gets cited by generative AI engines — ChatGPT, Perplexity, Claude, Gemini — when they generate full conversational responses to user queries. Three optimization endpoints, three sets of tactics, partially overlapping but not identical.
The disambiguation table
| Dimension | SEO | AEO | GEO |
|---|---|---|---|
| Goal | Rank on Google blue links | Appear in answer boxes | Get cited in generative responses |
| Primary engines | Google, Bing | Google AIO, Bing Copilot | ChatGPT, Perplexity, Claude, Gemini |
| Optimization endpoint | Position #1-10 | Position #0 (the box) | Citation list inclusion |
| Key signals | Backlinks, content depth, schema | FAQPage, structured data, definition leads | Brand mentions, authority, recency, source diversity |
| Maturity | 25 years (1999-) | 7 years (2018-) | 2-3 years (2023-) |
| Click destination | Your site | Sometimes your site, sometimes nothing | Often nothing (citations are visible but click rate under 5%) |
| Click-through rate | 30-50% on top result | 10-20% on AIO box | 2-5% per citation |
| Measurement | GSC, Ahrefs, rank trackers | GSC AIO insights, manual probes | Otterly.ai, Profound, manual probes |
The CTR row is the punchline. SEO drives clicks. AEO and GEO drive impressions and brand recall, but rarely clicks. If your business depends on CTR, SEO still matters more than the hype-merchants admit.
Where do they overlap?
The tactics partially intersect. Schema, content depth, technical health, and authority signals matter for all three. But the gravity centers differ.
Tactics that help all three
- Clean technical SEO (HTTPS, schema validation, fast LCP, mobile-friendly)
- Article schema with author Person + Organization
- FAQPage schema on Q&A sections
- Author E-E-A-T (named bylines, credentials, sameAs links)
- Internal linking, topical authority
Tactics SEO-specific
- Backlinks from DR 50+ sites
- Keyword targeting at exact-match level
- Competitive content depth (longer than competitors)
- Long-tail keyword expansion
- Page-level optimization for specific search intents
Tactics AEO-specific
- Definition leads (40-60 word answer in first paragraph)
- Structured answer formats (numbered lists, comparison tables)
- FAQPage schema with 5-8 question/answer pairs
- HowTo schema for tutorials
- Schema.org Article with
descriptionandheadlinealigned to query intent
Tactics GEO-specific
- Brand mentions across the web (Wikidata, Crunchbase, Reddit)
- Citation diversity (your brand mentioned by multiple authoritative sources)
- TLDR boxes labeled “TLDR” or “Summary” (LLM extraction targets)
- First-party data (numbers LLMs can’t get elsewhere)
- Recency signals (dateModified bumps, weekly content cadence)
- llms.txt and bot allow-listing in robots.txt
The Ahrefs December 2025 brand mentions study showed brand mentions correlate 3x more with AI visibility than backlinks1. That’s why GEO gravity sits on signals SEO doesn’t reward.
When each one matters most
| Situation | Priority order |
|---|---|
| New site, DR 0, < 6 months old | SEO → AEO → GEO |
| Established site, DR 30+, 2+ years | AEO → GEO → SEO maintenance |
| B2B SaaS targeting decision-makers | AEO → GEO → SEO |
| E-commerce / transactional intent | SEO → AEO → GEO |
| Solopreneur info content (this site) | SEO foundation → AEO structure → GEO authority |
| Local services | SEO + Local SEO → AEO |
500k.io sits in the “new site” row. SEO foundation first. We have schema discipline, llms.txt, robots allowing 22 LLM bots, fast LCP. AEO structure is in flight — every article ships with TLDR + FAQ + definition leads. GEO is the slowest-compounding. We’re at 0-2 weekly citations on Day 90 and that’s expected.
Is GEO just SEO with a new name?
No, and the founders saying yes are anchored to the wrong mental model.
SEO optimizes for ranking on a SERP. The goal is “be in position 1-10 when someone searches X.” GEO optimizes for citation in a generated answer. The goal is “be in the 2-7 sources the LLM cites when answering X.”
The mechanics differ:
- SEO ranking is determined by 200+ signals weighted by Google’s algorithm
- GEO citation is determined by retrieval — the LLM grabs the top N most relevant chunks from its index, then weights authority/recency/specificity for citation choice
A page can rank #1 on Google and never be cited by ChatGPT (happens often — overly long, no clean answer chunk, no schema). A page can be invisible on Google and cited by Perplexity 50 times/month (less common but real — usually a Reddit thread or a niche but factual blog post).
“Treating GEO as SEO with a new name is the single most expensive misunderstanding in 2026 marketing. The signals partially overlap but the optimization endpoint is different. Optimize for the endpoint, not the acronym.” — Maxime Le Morillon, building 500k.io in public
If you internalize one thing from this article, internalize that. SEO is ranking. AEO is answering. GEO is citing. Three jobs.
The order I’d attack them as a solo founder
Day 1-30: SEO foundation. Get the boring stuff right.
- HTTPS + sitemap + robots.txt allowing AI bots
- Article schema with Person + Organization
- Mobile Lighthouse 90+
- Fast LCP (under 2.5s)
- 5-7 articles published with proper schema
Day 31-90: AEO structure. Make every article extractable.
- TLDR box at top of every article (60-80 words, citation-magnet)
- FAQ section with 5-8 Q&A and FAQPage schema
- Definition lead under the first H2 (40-60 words)
- At least 1 comparison table per article
- Author byline + AuthorBio with verifiable credentials
Day 91-180: GEO authority. Earn citations.
- Wikidata + Crunchbase entries
- Reddit presence (genuine, not spammy — see How to Rank in Perplexity When You’re a DR 0 Founder)
- Podcast appearances on solopreneur shows (DR 50+ hosts)
- Guest posts on adjacent sites
- LinkedIn long-form weekly + 3 article shares with founder commentary
Day 181+: Compounding mode.
- Quarterly content refresh (dateModified bumps)
- Citation tracking (Otterly.ai or manual 30-query probe)
- Backlink earning via tier-1 outreach
- First-party data pieces (citation magnets)
That’s the realistic timeline. If you’re shipping 4 articles a week and treating Day 30 as “GEO is done,” you’ve burned the foundation and you’ll wonder why nothing compounds.
What I tell agency clients about the split
When I’m helping clients at The Kreators AI ($45M agency revenue combined with my co-founder Jack) think about AEO/GEO/SEO budget, I use this rough split:
- 50% effort on SEO foundation (technical, content depth, on-page)
- 30% effort on AEO structure (schema, answer formats, FAQ)
- 20% effort on GEO authority (brand mentions, distribution, recency)
For a solopreneur on 500k.io scale, the split shifts:
- 60% SEO foundation (because you have less to lose by getting boring stuff right)
- 25% AEO structure (because it’s mostly mechanical once you know the rules)
- 15% GEO authority (because citations compound slowly — invest, don’t expect)
The hype-merchants will tell you to spend 80% on GEO because “AI is the future.” The honest math: GEO returns at month 6+, SEO returns at month 2+, AEO returns at month 3+. Index-funding the foundation is the smarter play.
What changes in the next 12 months
I track this stuff weekly. Here’s where I see the AEO/GEO/SEO map shifting in 2026.
- Google AI Overviews will keep cannibalizing CTR. SEO clicks drop. AEO box wins matter more.
- ChatGPT Search will pass Google in some founder-economics queries (early Indie Hackers data already shows this for B2B SaaS pricing queries).
- Perplexity citation rates will normalize as more sites optimize. Early GEO mover advantage compresses.
- llms.txt will be mostly irrelevant — see llms.txt is mostly a placebo for why.
- Reddit signal will keep climbing. AI engines cite Reddit at 46.7% of all citations in some categories.
- The “AI search optimization” category will consolidate. Otterly.ai, Profound, and 2-3 others will absorb the long tail of consultancies offering “GEO services.”
My personal bet: by Q4 2026, “GEO” stops being a separate marketing function and becomes a checklist item under content strategy. Same way “mobile-first” was a thing in 2015 and now it’s just baseline.
FAQ
What’s the difference between AEO, GEO, and SEO?
SEO is ranking on Google’s blue links. AEO is appearing in answer boxes — Google AIO, Bing Copilot, featured snippets. GEO is getting cited by ChatGPT, Perplexity, Claude, Gemini in generative responses. Three battlegrounds, overlapping but distinct.
Should I do all three?
Yes, but not equally. SEO is foundation, AEO is the bridge, GEO is the frontier. Spend 50% on SEO foundation, 30% on AEO structure, 20% on GEO authority in year one.
Is GEO just SEO with a new name?
No. SEO optimizes for ranking; GEO optimizes for citation. A page can rank #1 on Google and be invisible to ChatGPT. A page can be uncited on Google and cited by Perplexity 50x/month. Different optimization endpoints.
Which acronym should I prioritize as a solo founder?
If your domain is under 6 months old: SEO foundation first, then AEO structure, then GEO. Don’t optimize for ChatGPT citations on a domain that isn’t even properly crawlable yet.
Are AEO and GEO the same thing?
No, but they’re close cousins. AEO targets answer engines (AIO, Copilot) with box-style direct answers. GEO targets generative engines (ChatGPT, Perplexity, Claude) with full LLM responses. AEO is older (2018-); GEO is the 2024-2026 evolution.
How do I measure GEO success?
Run a 30-query probe across ChatGPT, Perplexity, Claude, and AIO monthly. Track citations, query positions, branded vs unbranded. I track 30 founder-economics queries weekly with manual probes. Otterly.ai and Profound automate this for $50-200/mo.

FAQ
What's the difference between AEO, GEO, and SEO?
SEO is ranking on Google's blue links. AEO (Answer Engine Optimization) is ranking inside featured snippets and direct-answer boxes — Google AI Overviews, Bing Copilot quick answers. GEO (Generative Engine Optimization) is getting cited by ChatGPT, Perplexity, and Claude in their generative responses. Three battlegrounds, overlapping but distinct.
Should I do all three?
Yes, but not equally. SEO is foundation — schema, technical health, indexability. AEO is the bridge — structured answers, definition leads, FAQ schema. GEO is the new frontier — citations, brand mentions, authority signals. Spend 50% effort on SEO foundation, 30% on AEO structure, 20% on GEO authority in year one.
Is GEO just SEO with a new name?
No. SEO optimizes for ranking; GEO optimizes for citation. Different metrics, different tactics. A page can rank #1 on Google and be invisible to ChatGPT. A page can be uncited on Google and cited by Perplexity 50 times/month. The signals partially overlap but the optimization endpoints are different.
Which acronym should I prioritize as a solo founder?
If your domain is under 6 months old: SEO foundation first (schema, technical, indexability), then AEO structure (TLDR boxes, FAQ schema, definition leads). GEO citations come AFTER you have foundational trust signals. Don't optimize for ChatGPT citations on a domain that isn't even properly crawlable yet.
Are AEO and GEO the same thing?
No, but they're close cousins. AEO targets answer engines (Google AIO, Bing Copilot) — usually box-style direct answers next to traditional results. GEO targets generative engines (ChatGPT, Perplexity, Claude) — full LLM-generated responses with citation lists. AEO is older (since 2018-ish featured snippets); GEO is the 2024-2026 evolution.
How do I measure GEO success?
Run a 30-query probe across ChatGPT, Perplexity, Claude, and Google AI Overviews monthly. Track: number of citations, query positions, branded vs unbranded. I track 30 founder-economics queries weekly with manual probes. Otterly.ai and Profound automate this for $50-200/mo if you want the tooling.
