⭐️ Core Guides
AI Bot robots.txt Matrix — Comprehensive Comparison and Setup Guide
A unified reference guide that compares policy, robots.txt settings, and recommended scenarios for six major AI answer engines and LLM training bots on one screen, with copy-ready robots.txt templates for each scenario.
Complete Guide to Anthropic Bots (ClaudeBot · Claude-User · Claude-SearchBot)
Anthropic operates three bots for training (ClaudeBot), user browsing (Claude-User), and search indexing (Claude-SearchBot), each controllable independently via robots.txt; Anthropic officially commits to honoring robots.txt.
Complete Guide to Applebot-Extended — Apple Intelligence Training Control Token
Applebot-Extended is not an independent crawler but a robots.txt policy token that controls whether content collected by Applebot may be used to train Apple's generative AI models such as Apple Intelligence; blocking it does not affect Applebot crawling or Siri and Spotlight indexing.
CCBot (Common Crawl) Complete Guide
CCBot is an open web archive crawler operated by the nonprofit Common Crawl. Collected data is publicly distributed and has been used in LLM training by many AI researchers and companies (based on academic papers). robots.txt can block future collection, but it does not affect data already collected.
Google-Extended Complete Guide — A Policy Token, Not a Bot
Google-Extended is not an independent crawler but a robots.txt control token that governs whether data already collected by Googlebot may be used for Gemini model training and Vertex AI grounding—without affecting Google Search visibility or rankings.
Complete Guide to OpenAI Bots (GPTBot · ChatGPT-User · OAI-SearchBot · OAI-AdsBot)
OpenAI operates four purpose-specific bots for training (GPTBot), user browsing (ChatGPT-User), search indexing (OAI-SearchBot), and ad verification (OAI-AdsBot), each of which can be controlled independently via robots.txt.
Complete Guide to Perplexity Bots (PerplexityBot · Perplexity-User)
Perplexity operates two bots — PerplexityBot for search indexing and Perplexity-User for user-initiated requests; PerplexityBot honors robots.txt but Perplexity-User is officially documented as generally ignoring robots.txt.
Passage Ranking
Passage Ranking is a Google algorithm introduced in 2020 that indexes and ranks specific passages within pages separately from whole pages, enabling specific paragraphs in long pages to appear independently for various queries — the technical foundation for AEO answer extraction.
AI Citation Tracking Methodology
AI Citation Tracking is a methodology for systematically measuring how often and in what context AI answer engines such as ChatGPT, Perplexity, Claude, and Gemini cite your content — the foundational infrastructure for validating AEO and GEO performance.
AI Share of Voice
AI Share of Voice (AI SOV) is the proportion of brand citations within AI answers for a specific category or query pool — extending Les Binet's Share of Search concept to AI answer engine environments.
AI Visibility Score
AI Visibility Score quantifies how much a specific brand is exposed and cited in AI answer engines like ChatGPT, Perplexity, Gemini, and Naver Cue — a core KPI measuring brand digital asset value in the AI search era.
PAA (People Also Ask)
PAA (People Also Ask) is the 'People Also Ask' box in Google search results that provides related questions and direct answers, serving as a core data source for content strategy in both AEO and SEO.
Query Fan-Out
Query Fan-Out is the mechanism by which AI answer engines decompose one user question into multiple sub-queries, search many sources in parallel, and synthesize an answer.
Link Profile
Link Profile is the comprehensive characteristics of all backlinks a site receives — quantity, quality, domain diversity, anchor text distribution, and attributes (dofollow/nofollow) — the core unit of SEO authority analysis.
What Are Backlinks?
A backlink is when an external site links to your page — a trust signal for search engines and AI.
GEO Master Guide: 5-Area Checklist
An execution guide for Generative AI Optimization covering GEO's five areas: content, structure, technical, off-site, and measurement.
SEO vs AEO vs GEO: What Is the Difference?
SEO, AEO, and GEO are three strategies targeting search rankings, AI answers, and generative AI citations.
What Is AEO?
AEO is the practice of optimizing content so AI answer engines cite it.
What Is GEO?
GEO is the practice of optimizing content so generative AI cites it in answers.
What Is SEO?
SEO is the practice of optimizing content so it ranks prominently in search engines.
GitHub README · Profile SEO — A Core Channel for Developer SaaS
GitHub SEO is the practice of optimizing repositories and profiles for visibility and citation in search and AI-generated answers.
LinkedIn Post Search Visibility — B2B Off-Site Channel Optimization
LinkedIn SEO is the practice of exposing profiles and posts to LinkedIn search, external search, and AI-generated answers.
Substack · Newsletter SEO — Archive Search Visibility and Subscriber Assets
Newsletter SEO is the practice of exposing newsletter web archives to search and AI citation while growing subscriber assets.
Quora Answer Strategy — An English-Language AI Training and Citation Channel
Quora answer strategy is the practice of using Q&A platform answers for AI training, citation, and external visibility.
YouTube SEO — Optimizing Video Citations in the AI Answer Era
YouTube SEO is the practice of optimizing metadata and captions so videos are cited in search and AI-generated answers.
Black Hat SEO
Black hat SEO is the umbrella term for search ranking manipulation techniques that intentionally violate Google guidelines, pursuing short-term gains but causing penalties, index removal, and domain trust damage.
Comparison Content (X vs Y) — Comparison Content AI Cites Well
Comparison content is a format that compares two or more options to help users decide.
Content Hub — Extending Topic Clusters for User Experience
A content hub extends Topic Clusters to cover user experience and brand asset management.
Duplicate Content
Duplicate content is a state where identical or very similar content exists on multiple URLs, causing authority dilution and indexing confusion—a common technical SEO problem.
First-Person Experience Content
First-person experience content is content where the author's direct experience, observation, or experimentation is explicitly visible. It connects directly to the first E (Experience) in E-E-A-T and strongly influences AI answer engine citation priority.
Keyword Cannibalization
Keyword cannibalization is a common SEO problem where multiple pages on your site compete for the same keyword and search intent, causing authority dilution and ranking instability.
Statistics Page Strategy — The Content Format AI Cites Most
A statistics page is a content format that aggregates statistics and data on a specific topic to target AI citation.
Thin Content
Thin content refers to shallow pages that fail to provide sufficient value to users. The Helpful Content system detects it and lowers overall site quality—a common SEO penalty trigger.
Topic Cluster · Pillar-Cluster Model — Content Structure Design for the AEO Era
The Topic Cluster model is a content structuring methodology formalized by HubSpot in 2017. It connects subordinate cluster content to a central pillar page via internal links to accumulate topical authority—a core SEO and AEO structure.
YMYL (Your Money Your Life)
YMYL (Your Money Your Life) is a content category that can affect users' money, health, safety, and life—a high-risk area where Google applies E-E-A-T most strictly.
4 Types of Search Intent
Search intent is the true goal behind a user query, classified into four types: informational, navigational, commercial, and transactional.
Korean LLM Optimization
Korean LLM optimization is the work of optimizing content so global AI answer engines cite your content when answering Korean-language questions. Because Korean represents a smaller share of training data than English, it presents both higher barriers and distinct opportunities compared with English AEO.
How Naver SEO Works
Naver SEO aims for top visibility in unified search on Naver, Korea's leading search platform, where the channel-trust-centered C-Rank algorithm differs fundamentally from Google.
Why CEPs Matter More in the AEO Era
AI natural language questions share the same structure as CEPs, and CEP mapping is the starting point for AEO strategy.
Google Business Profile
Google Business Profile (GBP) is Google's free business listing tool. It is core local SEO infrastructure for exposing company information in local search, Google Maps, and Google AI Overviews, and a direct signal of entity authority.
Local SEO
Local SEO is the SEO subfield that optimizes for business visibility in specific geographic areas, with five core signals: Google Business Profile, NAP consistency, local keywords, local backlinks, and reviews.
Organic Traffic
Organic traffic is free search inflow acquired through SEO and content marketing. It is a business asset that runs continuously without ad spend and, long term, is the digital marketing channel with the highest ROI.
Owned Media
Owned Media is media channels (company site, blog, email, wiki) that a company directly owns and controls. Together with paid and earned media, it forms one of the three pillars of marketing media strategy and is the core foundation of SEO/AEO assets.
TOFU MOFU BOFU Marketing Funnel
TOFU/MOFU/BOFU are the three stages of the marketing funnel (awareness, consideration, decision) that classify the customer journey. Designing content, CTAs, and metrics for each stage forms the backbone of content strategy that converts SEO/AEO traffic into revenue.
What Is a CEP? (Category Entry Points)
A CEP is a cue—a purchase situation or context—that makes consumers think of a category.
Anchor Text
Anchor text is the clickable text displayed on a hyperlink. Google uses it as a key signal to understand the linked page's topic, making it important in both internal linking and external backlink strategy.
Canonical Tag
A canonical tag is an HTML meta tag that tells search engines 'this URL is the representative version' when duplicate or similar content exists across multiple URLs. It resolves duplicate content problems and concentrates PageRank on the canonical URL—a core on-page SEO tool.
Internal Linking Strategy
Internal linking strategy is the practice of semantically connecting pages within your own site to optimize topic authority and bot and user navigation.
Title Tag
A title tag is the title element in the HTML head—a core on-page SEO signal that identifies pages in search results and AI answers.
URL Slug
A URL slug is the string forming the path after the domain in a web page address. SEO best practices include keyword inclusion, hyphen use, lowercase, and short, clear structure.
Complete Guide to Article · NewsArticle · BlogPosting Schema
Article, NewsArticle, and BlogPosting are the most common schemas for reporting content body as structured data, strengthening E-E-A-T signals by specifying author, publish date, and images while increasing AI answer engine citation potential.
Featured Snippet
A Featured Snippet is a 'Position 0' SERP format where Google extracts part of a page's content and displays it as a direct answer at the top of search results. Introduced in 2014, it remains one of the most powerful SEO placements and a direct precursor to AEO answers, coexisting with Google AI Overviews.
Complete Guide to HowTo Schema — Why It Still Matters After Google Rich Results Removal
HowTo schema is the standard for reporting step-by-step guide content as structured data. Although removed from Google Search rich results, it retains value for step extraction and citation potential by AI answer engines.
JSON-LD Basics
JSON-LD is the Schema.org structured data insertion method recommended by Google.
Complete Guide to LocalBusiness Schema — Local Search Optimization for Korean SMBs
LocalBusiness schema is the standard for reporting offline store and service business location, hours, and contact information as structured data to increase visibility in local search and AI answer engine citations.
Complete Guide to Organization + Person Schema (E-E-A-T Foundation)
Organization and Person schemas are structured data that explicitly report the identity and authority of content creators to search engines and AI answer engines, forming the basis of E-E-A-T Authoritativeness and Trustworthiness signals.
Complete Guide to Product · Review · AggregateRating Schema
Product, Review, and AggregateRating are core ecommerce schemas that work together, reporting product information, reviews, and aggregate ratings as structured data to optimize for rich results and AI answer citations.
Rich Snippet
A Rich Snippet is a SERP format that displays additional visual information such as ratings, FAQ, price, and images in search results based on structured data (Schema.org), serving as a core SEO signal that improves CTR and AI answer citation potential.
Complete Guide to Speakable Schema — AEO-Direct Structured Data
Speakable is structured data that specifies speakable content areas for voice answers and AI answer engines. Google lists it as beta (limited), but it is the only AEO-specific schema that directly signals AI answer citation potential.
Core Web Vitals
Core Web Vitals are the three core user experience metrics defined by Google.
Crawlability
Crawlability is the ability of search engine and AI bots to access website pages and read content. It is the most basic condition for SEO and AEO, a required step that precedes indexing and ranking.
hreflang Tag
hreflang is an HTML attribute that tells Google about multilingual and multi-regional versions of the same content, showing the correct language and regional page to appropriate users and preventing duplicate content signals.
JavaScript SEO
JavaScript SEO is the technical SEO area of optimizing JavaScript-rendered web pages so search engines and AI bots recognize them correctly. The choice between SSR/SSG and CSR determines indexing feasibility.
Mobile-First Indexing
Mobile-first indexing is Google’s system for crawling, indexing, and ranking based on a site’s mobile version. With full rollout completed in 2024, it is now the default premise of SEO.
Rendering
Rendering is the process of processing HTML, CSS, and JavaScript to produce the final screen seen by users and bots. The choice among CSR, SSR, SSG, and ISR determines SEO and AEO feasibility.
Site Architecture
Site architecture is the overall design of page hierarchy, URL structure, and internal linking on a website. It simultaneously determines crawl efficiency, indexing quality, and user navigation experience — a foundational SEO element.
Subdomain vs Subdirectory
Subdomain (subdomain.example.com) and subdirectory (example.com/path/) are two URL structure choices for content. Subdirectories share domain authority and are advantageous in most SEO cases.
