AI SEO Checklist with GEO and AEO - Tommaso Liu

How to Use This AI SEO Checklist

SEO in 2026 means optimizing for two audiences simultaneously: Google’s ranking algorithm and the AI systems (ChatGPT, Perplexity, Google AI Overviews) that are now generating answers directly.

Most checklists cover one or the other. This one covers both.

Work through each section in order:

  • Sections 1-4 are foundational – entity authority, content structure, technical crawlability, and GEO optimization. Start here.
  • Section 5 covers off-page authority – the signals AI systems use as a proxy for trustworthiness.
  • Section 6 is platform-specific: Google AI Overviews, Perplexity, and ChatGPT each weight signals differently.
  • Section 7 covers monitoring – how to track whether your content is actually getting cited.

1. Brand and Entity Authority

0 / 7
▾

AI systems build their understanding of your brand from every source they can find. Inconsistent or thin brand definition across the web means you get cited less — or not at all.

Consistent brand definition across all sourcesSame name, description, and positioning on your site, GBP, directories, and press mentions
Topical clusters with strong pillar pagesOne pillar page per core topic; cluster articles link back with descriptive anchor text
Semantic internal linkingInternal links use contextual anchor text that matches the target page topic
Wikipedia or Wikidata presenceIf brand meets notability criteria, a Wikipedia entry significantly strengthens entity authority
Original research or proprietary data publishedFirst-party data positions your brand as a primary source that AI systems cite directly
Named author with verified credentialsAuthor bio with role, expertise, and linked professional profiles on all key content
Organization schema on homepageDefines brand name, logo, founding date, and contact details for AI entity recognition

2. Content Structure and AI Readability

0 / 8
▾

AI systems extract answers differently from how Google ranks pages. Content that leads with the answer, uses clear structure, and maintains high fact density gets cited. Content that buries the point does not.

Answer-first content structureEvery page leads with a direct answer to the core question before expanding
Short semantic paragraphsOne idea per paragraph; under 150 words each; no walls of text
Question-based headersH2s and H3s framed as questions where relevant; matches how people query AI tools
High fact densityNamed statistics, specific numbers, cited sources, and concrete outcomes throughout
Lists, tables, and step-by-steps used where appropriateStructured formats are easier for AI systems to extract and reproduce accurately
Deep FAQ sections on key pages5 or more standalone Q and A pairs; each answer works without surrounding context
Zero ambiguity in definitionsEvery non-obvious term defined inline on first use; no assumed knowledge
Video transcripts publishedTranscripts of video content make spoken information indexable by both Google and AI systems

3. Technical SEO and AI Crawlability

0 / 8
▾

AI systems crawl your site independently from Google. Most standard technical SEO applies here too — but there are specific AI crawlability steps that most sites haven't taken yet.

AI bots allowed in robots.txtGPTBot, ClaudeBot, PerplexityBot, and GoogleOther not blocked
FAQ schema on key pagesFAQPage markup on service, feature, and content pages; feeds AI answer extraction directly
HowTo schema on process pagesStep-by-step content marked up with HowTo schema where applicable
Article schema on blog contentIncludes author, datePublished, dateModified — supports E-E-A-T and freshness signals
Core Web Vitals passingLCP under 2.5s, INP under 200ms, CLS under 0.1 — verified in Google Search Console
Mobile-first pages confirmedAll key pages fully functional and fast on mobile devices
XML sitemap submitted and cleanOnly canonical, indexable URLs included; submitted to Google Search Console
Server logs monitored for AI bot activityConfirms which AI crawlers are visiting, how often, and which pages they prioritize

4. GEO and Citation Optimization

0 / 7
▾

Getting cited in AI-generated responses is not the same as ranking on Google. It requires a different set of signals — authoritative sources, high fact density, and content structured for extraction, not just for reading.

Authoritative external citations in contentEvery factual claim linked to a primary source: studies, official data, named institutions
Expert quotes and named testimonialsNamed individuals with verifiable credentials quoted directly; not anonymous reviews
Content updated for freshnessKey pages reviewed and updated regularly; dateModified in schema reflects actual changes
Third-party brand mentions activePress, directories, review platforms, and partner sites that AI systems index and cite
Content covers full query intentEach page answers the core question, related questions, and follow-up questions in full
Case studies with named outcomesReal clients, specific results, quantified impact — AI systems prefer citable specifics over vague claims
Definitions published for core terms in your nicheGlossary-style definitions position your site as a reference source for AI answer extraction

5. Link Building and Off-Page Authority

0 / 6
▾

Off-page authority still matters for AI search — AI systems use link signals as a proxy for trustworthiness. But the sources that matter most are those that AI systems themselves index and cite.

Links from authoritative sources in your nicheEditorial links from publications and sites that AI systems treat as reference sources
Digital PR for original researchData studies and industry reports pitched to publications; earn both links and AI citations
Listed on relevant directories and platformsIndustry directories, review platforms, and aggregators that AI systems scrape and index
Unlinked brand mentions convertedFound mentions without a link and requested the link; both linked and unlinked mentions influence AI
Guest content on authoritative publicationsBylined articles on recognized industry sites strengthen author entity and brand authority
Podcast and interview appearancesNamed mentions in transcribed or published interviews contribute to brand entity signals

6. Platform-Specific Optimization

0 / 6
▾

Google AI Overviews, Perplexity, and ChatGPT draw from different source types and weight signals differently. Optimizing only for one platform leaves visibility on the table.

Google AI Overviews: E-E-A-T signals strongExperience, expertise, authoritativeness, and trustworthiness demonstrated across all content
Google AI Overviews: structured data completeFAQPage, HowTo, and Article schema implemented on relevant pages
Perplexity: Reddit and forum presencePerplexity heavily indexes Reddit and community forums; participate where your audience is active
Perplexity: content freshness prioritizedPerplexity weights recency; key pages updated regularly with dateModified in schema
ChatGPT: Wikipedia-style clarity and structureChatGPT favors encyclopedic content; definitions, context, and neutral framing perform well
Global AI search differences monitoredAI search behavior varies by region and language; test prompts in your target markets

7. Monitoring and AI Performance Tracking

0 / 7
▾

Most SEO reporting tools don't track AI visibility yet. Building a monitoring system now gives you a baseline and lets you measure what actually works as the landscape shifts.

AI citations tracked with a dedicated toolOtterly.AI, Geoptie, AIclicks, or Rankscale.ai — at least one tool monitoring AI mentions
AI share of voice monitoredTrack how often your brand appears vs competitors in AI responses for target queries
AI bot traffic in GA4Custom dimension or server log analysis to isolate GPTBot, ClaudeBot, PerplexityBot traffic
Summary accuracy checked regularlyManually verify that AI-generated summaries of your brand and content are accurate
Manual prompt testing monthlySearch for your core topics in ChatGPT, Perplexity, and Google AI Overviews; record results
Winning citations reverse-engineeredWhen a competitor appears in AI results, identify what source or content triggered the citation
Traditional SEO metrics maintainedRankings, organic traffic, and Search Console data tracked alongside AI metrics — not replaced by them

FAQs About AI SEO Checklist

What is AI SEO?

AI SEO is the practice of optimizing your website to appear in AI-generated search results — including Google AI Overviews, ChatGPT, Perplexity, and Gemini — in addition to traditional organic rankings. It combines established SEO fundamentals with newer techniques focused on entity authority, content structure, and citation signals that AI systems use to select and attribute sources.

Traditional SEO optimizes for ranking positions on a results page. AI SEO optimizes for being selected as a source inside a generated answer. The signals overlap — authority, relevance, technical health — but AI systems also weight answer-first structure, fact density, named entities, and consistent brand definition across third-party sources in ways that Google’s ranking algorithm does not.

No. GEO (Generative Engine Optimization) is a layer on top of SEO, not a replacement for it.

A site with weak technical SEO, thin content, and no backlinks will not appear in AI-generated responses regardless of how well it is optimized for GEO.

The foundation (crawlability, content quality, authority) remains the same. GEO adds the signals that determine whether a well-built site gets cited by AI systems.

Start with Gemini / Google AI Overviews.

It appears directly in Google Search and has the broadest reach.

ChatGPT matters most for product and service recommendations, where users ask directly for suggestions.

Perplexity is the third priority for informational and research queries, particularly in English-speaking markets.

The good news is that the core optimization signals (entity authority, structured content, high fact density) improve visibility across all three simultaneously.
