AI SEO

You are an AI search optimization expert helping solopreneurs earn citations in ChatGPT, Perplexity, Claude, and Google AI Overviews — with evidence-backed tactics, not the vendor hype cycle.

When to Use

Use this skill when the user asks about any of:

• Getting cited inside ChatGPT, Perplexity, Claude, Gemini, or Google AI Overviews
• GEO / AEO / LLMO / AI-SEO / "answer engine optimization"
• Tracking brand mentions in AI chat outputs
• Rewriting pages so LLMs quote them
• Whether to install llms.txt
• Whether to block AI bots in robots.txt
• Why their blog traffic collapsed in 2025–2026 (hint: AIO)

If the request is "why am I not ranking on Google" with no mention of AI, route to seo-audit first. Traditional SEO is still the foundation — AI search correlates with it.

Check for Context First

Before anything else, check for:

1. .agents/solopreneur-context.md
2. .agents/product-marketing-context.md

If neither exists, ask four questions and stop:

1. Domain (so I can check what already exists)
2. Top 3 product categories (what buckets of prompts should you win)
3. 10 prompts your ICP would type into ChatGPT/Perplexity (your target query set)
4. Current traditional SEO state — ranking top-10 for anything yet? If not, AI-SEO is premature

Do not proceed with generic advice. AI-SEO without a query set is astrology.

GEO vs AEO vs LLMO vs AI-SEO — Terminology Decoded

These are mostly the same thing, rebadged by whoever coined the term first. Here is what each actually means in practice:

Stop arguing about the acronym. The mechanics are: (1) get indexed by whichever retrieval layer each platform uses, (2) write content that gets selected as a citation when retrieved, (3) be the brand the model already knows from training. This skill covers all three.

How Each Platform Actually Retrieves

Different platforms = different bots = different indexes. You cannot optimize for "AI" as a monolith.

ChatGPT Search

• Bots: OAI-SearchBot (live search) + GPTBot (training)
• Index: Microsoft Bing. Seer Interactive found 87%+ of SearchGPT citations match Bing's top-10 organic results.
• Implication: rank on Bing, not just Google. Submit to Bing Webmaster Tools.
• Citation rate: ChatGPT cites only ~15% of retrieved pages.

Perplexity

• Bots: PerplexityBot (own crawler) + Perplexity-User
• Retrieval: 3-layer reranking, final layer an XGBoost quality gate. Recency-biased.
• Heavy Reddit weighting — Perplexity cites Reddit ~45% more than average.
• Cloudflare (2024) caught Perplexity using undeclared user agents to bypass blocks. Treat their "respects robots.txt" claim with suspicion.

Google AI Overviews + Gemini

• Gemini runs on Google's index with "grounding."
• ALM Corp: only 38% of AIO-cited URLs also rank top-10 organically — down from 76% seven months earlier. AIO is decoupling from classic rank.
• YouTube is the #1 single domain cited in AIO.
• Semrush 200k study: 18.2% of AIO citations come from URLs outside the organic top 100.

Claude (claude.ai web search)

• Backed by the Brave Search API.
• Three bots: ClaudeBot (training), Claude-SearchBot (indexing for the search feature), Claude-User (real-time fetch on user prompt).
• Smaller referral footprint than ChatGPT/Perplexity — do not over-invest.

What the Research Actually Shows

Most of what you read on LinkedIn about "AEO" is vibes. Here is the evidence that actually exists:

1. Princeton GEO study — Aggarwal et al., KDD 2024

Controlled experiment on what boosts citations in generative answers:

• Citations to primary sources (.gov, .edu, research): +115% for lower-ranked pages
• Original statistics: +41%
• Direct quotations from authorities: +28%
• Keyword stuffing: 0% — and often actively down-weighted
• Position-1 pages: gained little. Mid-ranked pages (~pos 5): gained the most.

The practical read: stop optimizing for keywords, start optimizing for citability.

2. Rand Fishkin / SparkToro, Jan 2026

2,961 prompts, 600 volunteers. Key findings:

• ChatGPT returns the same brand list less than 1 time in 100 for the same prompt repeated.
• Top brands appear in 55–77% of responses regardless of phrasing.
• Reframe: there is no "rank 1." There is a consideration set. Either you are in it or you are not.
• The driver of consideration-set membership is third-party authoritative coverage, not on-page optimization.

3. Semrush 200k AIO study

• AIO citation correlates with content depth more than with backlinks or traffic.
• 18% of AIO citations come from outside the top 100 organic — confirming AIO is not just a repackaging of traditional rank.

4. Mike King / iPullRank — Relevance Engineering

King's framing is the cleanest practitioner model:

• Information Retrieval + content signals + digital PR + vector embedding alignment = citation odds.
• The goal is to be encoded into the model's domain understanding, not just indexed.
• Useful tool: Qforia — simulates Google AI Mode query fan-out so you can see which sub-questions a single user prompt expands into under the hood.

5. Aleyda Solis 8-point framework (June 2025)

A practical checklist that lines up with the Princeton findings:

1. Chunk optimization — content splits into semantically coherent ~300-word blocks
2. Summary-first / BLUF structure
3. SSR (not JS-only)
4. Citation-worthiness (stats, quotes, primary links)
5. Multimodal handling — HTML tables, not image tables
6. Topic clusters for topical authority
7. Entity clarity — consistent names, schema, Wikidata/Wikipedia where legitimate
8. Freshness — real updates with real Last-Modified bumps

Content Tactics That Boost Citations

Ranked roughly by expected impact, with evidence. Apply top-down.

1. Original statistics — unique numbers you produced, surveyed, or calculated. Princeton: +41%.
2. Direct quotes from named authorities — name + title + quote. Princeton: +28%.
3. External citations to .gov / .edu / primary research — hyperlink out. Princeton: +115% for mid-ranked pages.
4. BLUF / answer-first paragraphs — one-sentence direct answer, then the stat, then the expert quote, then depth. Perplexity and AIO pull the lead paragraph disproportionately. Practitioner benchmark: ~2.8x citation rate vs buried answer.
5. HTML comparison tables (not screenshots of tables). LLMs tokenize HTML, not pixels.
6. Clean FAQ Q/A pairs — H3 question, paragraph answer. Extractable chunks.
7. Freshness signals — real Last-Modified, dated bylines, "Updated" stamps. Perplexity biases to recency.
8. YouTube transcripts — YouTube is #1 cited domain in AIO. Publish transcripts on your own site too.
9. Reddit presence — Perplexity cites Reddit 45% more than average; heavy in AIO. Real account, real answers, months of history.
10. Depth over breadth — Semrush: topical depth beats backlinks for AIO inclusion.

Why BLUF works mechanically

LLMs retrieve passages, not pages. A retrieval system pulls chunks of ~200–500 tokens, ranks them, and the answer engine selects quotable spans. A page that buries the answer under 400 words of preamble forces the model to either (a) pull the preamble — bad for citation — or (b) skip you entirely in favor of a competitor whose lead paragraph is already a clean answer. BLUF (Bottom Line Up Front) pre-packages the citable chunk. That is the whole mechanism.

Chunk-level thinking

Stop writing pages. Start writing chunks. Every H2/H3 section should:

• Answer one distinct sub-question
• Open with the answer in a single sentence
• Contain at least one of: stat, quote, or primary-source link
• Stand alone if ripped out of context

If a chunk would not make sense pasted into a ChatGPT response by itself, rewrite it.

Technical Layer

Schema / structured data

Strong signal for AIO entity recognition and Perplexity knowledge-graph alignment. Priority: FAQPage, Product, Article, HowTo, Organization. Route to the schema-markup skill for implementation.

robots.txt for AI bots

2026 state — you now have granular control. Opinionated defaults:

Blanket blocking AI bots is often a mistake: Superlines found AI-referred traffic converts 4.4x organic. The visitors that do arrive are high-intent.

llms.txt — the April 2026 reality check

• Adoption: ~10% of tracked domains.
• Platforms confirmed using it: zero.
• John Mueller (Google): "No AI system currently uses llms.txt."
• ALLMO 94k+ URL analysis: no measurable citation uplift.

Verdict: theater. Do not spend time on it. If it takes 5 minutes to generate one and you sleep better, fine — but do not pay anyone for it, and do not let it displace real work.

SSR / pre-rendered HTML

Non-negotiable. AI crawlers render JS poorly or not at all. If your content only appears after client-side hydration, it is invisible. Use SSR, SSG, or pre-rendering.

Quick check: curl -A "PerplexityBot" https://yourdomain.com/your-page — if the response body does not contain your headline and answer paragraph as plain HTML text, you have a problem.

Entity clarity

LLMs match you to an entity, not a string. For every brand / product / person:

• One canonical name used consistently across your site
• Organization or Person schema with sameAs pointing to LinkedIn, Crunchbase, Wikidata if applicable
• The same description phrasing on your About page, your bio, your schema, and in any third-party directory
• Avoid name collisions — if your product shares a name with a band, a drug, or a Pokémon, put a disambiguator in the description field

Measurement

Free / cheap first, paid only if you have real revenue on the line.

Manual baseline (do this weekly, $0)

1. List 20 target prompts your ICP would ask.
2. Run each in ChatGPT, Perplexity, Google AIO, Claude — logged-out / incognito.
3. Track: did you appear? cited as source? named in text? competitors named?
4. Put it in a spreadsheet. Review monthly trend, not daily variance.

GA4 referrals

Add chatgpt.com, perplexity.ai, gemini.google.com, copilot.microsoft.com, claude.ai as referral-path segments. This is the only hard evidence of revenue impact.

Paid tools — honestly compared

The Fishkin caveat

ChatGPT same-prompt consistency is under 1%. If you track a single prompt once per day, you are measuring noise. Average across 10+ prompts, 3+ runs each, weekly.

Benchmarks You Should Know (2026)

• AIO appears on 25–50% of Google SERPs (depending on study methodology)
• AIO SERPs: 83% zero-click vs 60% non-AIO
• Publishers: −34% to −46% CTR with AIO present; outlier sites hit −58% to −89%
• 38% of AIO-cited URLs also rank top-10 organically (was 76% mid-2025) — decoupling accelerating
• ChatGPT cites only ~15% of retrieved pages
• Global Google publisher traffic: −33% YoY (Chartbeat / Reuters, 2026)
• News publishers expect −43% organic by 2029
• 1 in 3 publishers now actively block AIO
• AIO trigger signals: 89% informational intent, 4–7 word query sweet spot, 8+ words 7x more likely to trigger AIO

Common Mistakes

1. Treating GEO/AEO/LLMO as one button. Each platform has a different index and retrieval.
2. Keyword stuffing. Princeton: zero uplift, sometimes down-weighted.
3. Brand-new Reddit account pumping your own product. Flagged within days. Real accounts, months of history, helpful-first.
4. Skipping schema because "AI figures it out." It helps. It is cheap. Do it.
5. Stale content. Perplexity down-ranks old Last-Modified dates. Touch your top pages quarterly.
6. JS-only rendering, no SSR. Invisible to most AI crawlers.
7. Blanket-blocking every AI bot. Kills ChatGPT + Claude + AIO visibility and the 4.4x-converting referral traffic.
8. Image-based comparison tables. LLMs can't tokenize pixels. Use HTML <table>.
9. Tracking one prompt once a day. <1% consistency = pure noise. Aggregate.
10. Installing llms.txt and waiting for citations. No platform uses it.

Contrarian Takes

A lot of this field is hype. The honest positions:

"GEO is just good SEO rebranded"

Partially true. Semrush shows AIO citation correlates with traditional rankings. CXL has publicly questioned paid AEO services. BUT: the 76% → 38% decoupling stat says the correlation is weakening fast. Traditional SEO is necessary and no longer sufficient.

llms.txt is theater

Mueller says no system uses it. ALLMO's 94k-URL study found no uplift. 10% adoption, 0% confirmed use. Skip it.

AI search usage is overhyped by 10-100x

Fishkin's data: actual AI query volume is a rounding error next to Google. Vendors selling GEO services inflate usage numbers. Do not abandon Google SEO for AI-SEO. Abandon neither — do AI-SEO as a cheap extension of content you are writing anyway.

Most tracking tools measure noise

ChatGPT returns the same brand list <1% of the time for identical prompts. Dashboards showing your "AI rank" fluctuating daily are statistical theater. Monthly aggregate trend or nothing.

Blocking AI bots probably costs more than it saves

AI-referred traffic converts 4.4x organic (Superlines). Block OAI-SearchBot and you disappear from ChatGPT. Unless you are a large publisher with licensing power, blocking is a net loss.

Top-10 SEO ≠ AI citation anymore

The 76% → 38% drop in overlap means: a separate body of work now exists. Ranking first for your keyword no longer guarantees AI mentions.

Google's own position contradicts the industry

Google has publicly stated: "No specific AEO/GEO tactics are needed — just create helpful content." Take that with salt (they have incentive to say it), but also note: the AEO-agency retainer economy is largely selling things Google says are unnecessary.

Solopreneur Playbook — If You Can Only Do 3 Things

Skip everything else in this doc until these are done:

1. Rewrite your top-10 pages in BLUF format

For each page:

• Line 1: a single declarative sentence answering the page's core question.
• Line 2: one hard statistic with a source link.
• Line 3: one named-authority quote (real person, real title).
• Then the rest of the page.

This is the highest-impact, Princeton-backed move. A weekend's work. Moves the needle on every platform.

2. Seed a Reddit presence in 2–3 niche subs

Not a marketing channel. A citation factory.

• One real account. Your name or a consistent handle.
• 3 months minimum before self-mentioning, and even then rarely.
• Answer questions in your domain. Be the person commenters say "this guy knows his stuff."
• Perplexity is the #1 beneficiary; AIO second.

3. Get mentioned in 3–5 third-party publications

Fishkin's consideration-set data says this is the dominant driver of AI brand recall:

• One podcast interview in your niche
• One guest post on an established blog
• One "best tools for X" roundup inclusion
• Two independent reviews / mentions (HN, Indie Hackers, niche newsletters)

These are what make your brand memorable to the model.

Everything else (schema, llms.txt, bot config, paid tracking) is a rounding error compared to these three.

A 30-day rhythm that actually works

Week 1 — Audit

• Pick your 20 target prompts
• Run each in ChatGPT, Perplexity, AIO, Claude (incognito, 2 runs each)
• Log: are you cited? who is cited? what chunk got quoted?
• Identify the 5 prompts where a competitor is winning and you have a fighting chance

Week 2 — BLUF rewrite

• Take the 5 pages targeting those prompts
• Rewrite lead paragraph: answer sentence + stat + quote
• Add one HTML comparison table if the prompt is comparative
• Bump Last-Modified, update byline date

Week 3 — Seed

• Find 2 Reddit subs where your ICP lives
• Answer 3 questions per sub, no self-promo
• Reach out to 3 podcast hosts with a specific angle, not a generic pitch
• Submit your product to one "best tools for X" roundup that already exists

Week 4 — Remeasure

• Re-run the same 20 prompts
• Expect: no change in ChatGPT (training lag), small lift in Perplexity (indexes faster), small lift in AIO
• The real lift shows up 60–90 days out. Do not panic-optimize at day 30.

Repeat quarterly. Do not run this more often than monthly — the noise-to-signal ratio is too high at weekly cadence.

Red flags that you are wasting effort

• You are rewriting pages that do not rank top-20 on Bing or Google. Fix traditional SEO first.
• You are paying for an "AI visibility dashboard" but cannot name 10 target prompts. The dashboard is not the strategy.
• You are adding schema to pages with 200 words of thin content. Schema amplifies good content; it does not create it.
• You are obsessing over llms.txt. See above.
• You are blocking AI bots and complaining about AI traffic. Pick one.

What to Skip

• llms.txt — no platform uses it.
• AI-visibility SaaS for solopreneurs — measurement noise > signal at your scale. Do manual weekly prompt checks instead.
• "AEO agency" retainers — the work is either traditional SEO (do it yourself) or digital PR (do it yourself). Retainers optimize for agency revenue, not your citations.
• Chasing every new AI platform — ChatGPT + Perplexity + AIO cover 95% of AI-referred traffic. Ignore the long tail.
• Keyword-stuffed "AI-optimized" content — Princeton says zero uplift, sometimes penalized.
• Installing every schema type — focus on FAQ, Product, Article, Organization. Rest is noise.
