## SEO & GEO Research Index

Brass-SEO curates the primary literature on SEO and generative-engine optimization for SEO practitioners, content marketers, and business owners.

### Topics covered

- **AI Citation & GEO** — https://brass-seo.com/research/ai-citation
  Peer-reviewed research on how AI search engines select and cite sources. Key findings: adding concrete numerical statistics raised AI search visibility by up to 40% (Aggarwal et al., KDD 2024); 37% of AI-cited domains absent from traditional search results for the same queries (Zhang et al., 2025); metadata freshness, Semantic HTML, and schema.org markup are the strongest cross-platform GEO signals (Kumar & Palkhouski, 2025).

- **Crawling & Indexing** — https://brass-seo.com/research/crawling-indexing
  Official specifications on how search engines crawl and index the web. Key facts: sitemaps.org protocol sets a 50,000 URL / 50 MB per-file limit; RFC 9309 (IETF, 2022) establishes that allow rules take precedence over conflicting disallow rules; Googlebot fetches only the first 2 MB of any file; IndexNow supports batches up to 10,000 URLs but Googlebot is not a participant; Google's robots meta tag documentation states nosnippet also blocks a page's content from being used as a direct input for AI Overviews and AI Mode, and max-snippet:[number] limits how much can be used (max-snippet:0 equals nosnippet).

- **Core Web Vitals** — https://brass-seo.com/research/core-web-vitals
  Official thresholds and independent benchmarks on CWV. Key facts: Good thresholds are LCP ≤2.5s, INP ≤200ms, CLS ≤0.1 (75th percentile of real Chrome user loads); 43% of mobile sites pass all three metrics (Web Almanac 2024); CrUX field data (not Lighthouse lab scores) determines ranking eligibility; Google states CWV is a tiebreaker, not a dominant standalone factor.

- **Structured Data** — https://brass-seo.com/research/structured-data
  Adoption benchmarks, W3C specifications, and AI retrieval research. Key facts: JSON-LD is on 41% of pages (Web Almanac 2024, up from 34% in 2022); schema.org defines 900+ types maintained by Google, Microsoft, Yahoo, Yandex; standard JSON-LD alone did not produce expected AI retrieval gains — enhanced entity pages with dereferenceable linked data produced a 29.6% RAG accuracy improvement (Volpini et al., 2026); in August 2023 Google removed HowTo rich results and limited FAQ rich results to authoritative government and health sites, but the markup stays valid and still helps AI systems extract self-contained answers.

- **Ranking Signals** — https://brass-seo.com/research/ranking-signals
  First-party Google disclosures and foundational research. Key facts: Google confirms 17 named active ranking systems; the 2024 Content Warehouse API leak (confirmed authentic) documented NavBoost click signals, a siteAuthority attribute, and a hostAge factor; Google's three-stage model is crawl → index → serve; a page can be crawled but not indexed.

- **E-E-A-T & Content Quality** — https://brass-seo.com/research/eeat-content-quality
  Google's Quality Rater Guidelines and academic credibility research. Key facts: Google's Quality Rater Guidelines (168 pages) define Experience, Expertise, Authoritativeness, and Trustworthiness — Experience was added in December 2022; YMYL designates health, finance, legal, and safety pages as highest scrutiny; human rater judgments feed algorithm training, not individual page ranking; Fogg et al. (2003) found 94% of negative credibility judgments had a design component; Metzger (2007) identified dual-process credibility evaluation; Google's Article structured data guidance strongly recommends author markup (Person type plus a url or sameAs to a bio, about, or profile page) as the machine-readable half of E-E-A-T authorship.

- **Knowledge Graph & Entity SEO** — https://brass-seo.com/research/knowledge-graph-entities
  Google's Knowledge Graph documentation, Wikidata, and entity disambiguation research. Key facts: Knowledge Graph launched May 2012 with 500 million entities and 3.5 billion facts on a 'things, not strings' philosophy; Wikidata (Vrandečić & Krötzsch, CACM 2014) is a primary Knowledge Graph data source; the sameAs JSON-LD property is the primary entity disambiguation mechanism; entity linking is a prerequisite for both search ranking and AI retrieval (Hogan et al. 2021).

- **Helpful Content System** — https://brass-seo.com/research/helpful-content-system
  Google's HCS documentation and evolution. Key facts: HCS launched August 2022 as a site-wide classifier (not page-level); recovery operates on a timescale of months; AI-generated content is not inherently penalized — quality and helpfulness determine ranking eligibility; HCS was integrated into core ranking in the March 2024 core update (45-day rollout); scaled content abuse spam policy (2024) explicitly covers high-volume AI content aimed at ranking manipulation.

- **Local Search Ranking** — https://brass-seo.com/research/local-search-ranking
  Google's local ranking guidance and Business Profile guidelines plus the Whitespark and BrightLocal studies. Key facts: Google names three local ranking factors (relevance, distance, prominence); Google's guidelines require the real-world business name with no keyword stuffing (violations risk suspension); Whitespark's 2026 report (47 experts) ranks open-at-search-time 5th, visible address 7th, review recency 11th; BrightLocal's 2026 survey finds 97% of consumers read local reviews and 45% use AI tools for local recommendations.

- **Query Understanding** — https://brass-seo.com/research/query-understanding
  The Transformer and BERT papers plus Google's BERT and MUM announcements. Key facts: the Transformer ('Attention Is All You Need', Vaswani et al. 2017) underpins BERT and MUM; BERT (Devlin et al. 2018) scored 80.5% on GLUE and 93.2 F1 on SQuAD v1.1; Google applied BERT to Search in October 2019, affecting about 1 in 10 U.S. English searches; MUM (May 2021) is built on T5, described as 1,000x more powerful than BERT, trained across 75 languages and multimodal.

- **JavaScript SEO & Rendering** — https://brass-seo.com/research/javascript-seo-rendering
  Official Google documentation and HTTP Archive data on how Googlebot renders JavaScript. Key facts: Google processes pages in three phases (crawl, render, index) and rendering is deferred via a queue, run by a headless evergreen Chromium; the Web Rendering Service clears Local Storage, Session Storage, and cookies between page loads and does not support WebSocket or WebRTC; Google calls dynamic rendering a deprecated workaround and recommends server-side rendering, static rendering, or hydration; the 2024 Web Almanac found a 558 KB median mobile JS payload with 44% of delivered bytes unused at the median.

- **Canonicalization & Duplicate Content** — https://brass-seo.com/research/canonicalization-duplicate-content
  Google documentation and RFC 6596 on canonical URLs and duplicate content. Key facts: Google states a canonical declaration is 'a hint, not a rule' and may choose a different canonical than you do; 'some duplicate content on a site is normal and it's not a violation of Google's spam policies' (no penalty); canonical methods by strength are redirects and rel=canonical (strong) and sitemap inclusion (weak), with the link element accepted only in the page head; RFC 6596 (Ohye & Kupke, IETF, April 2012, Informational) defines the cross-engine rel=canonical relation.

- **Mobile-First Indexing** — https://brass-seo.com/research/mobile-first-indexing
  Google documentation and HTTP Archive data on mobile-first indexing. Key facts: Google uses the mobile version of a site's content, crawled with the smartphone agent, for indexing and ranking; Google announced completion in October 2023, ending a migration begun in 2016 (HTTP Archive confirms the seven-year migration completed in 2023); parity requirements include same content, same structured data, equivalent title and meta description, and same robots tags across mobile and desktop; the 2024 Web Almanac found 94% of mobile pages pass the viewport check and a 364-versus-400 word mobile-desktop content gap.

- **Do Clicks Affect Ranking? (Navboost)** — https://brass-seo.com/research/click-signals-ranking
  Peer-reviewed research, sworn testimony, and Google's own statements on click signals. Key facts: Joachims (KDD 2002) established clickthrough data as implicit relevance feedback for training ranking; click data is biased by position, the problem click models like Chapelle & Zhang (WWW 2009) correct; in sworn 2023 U.S. v. Google testimony, VP of Search Pandu Nayak confirmed Navboost is a 'core' system that 'memorizes past clicks,' is 'trained on user data,' and is 'certainly a factor' but 'by no means the only factor'; Google's 'How Search Works' describes measuring clicks in live experiments as aggregate evaluation; in United States v. Google (August 5, 2024) the court ruled Google an illegal search monopolist, and the 2025 remedy ordered Google to share user-interaction data with competitors, treating click data as material to search quality.

- **AI Crawler Access & Control** — https://brass-seo.com/research/ai-crawler-control
  Provider crawler documentation and independent adoption data on controlling AI bots. Key facts: OpenAI runs GPTBot (training), OAI-SearchBot (ChatGPT search), and ChatGPT-User (live fetch) with separate robots.txt tokens; Anthropic runs ClaudeBot, Claude-User, and Claude-SearchBot; Google-Extended controls Gemini training and grounding without affecting Google Search inclusion or ranking; blocking a provider's training crawler while allowing its search crawler opts a site out of AI training without losing AI-answer citations; a valid llms.txt appeared on only 2.13% of desktop pages in 2025 (Web Almanac) and GPTBot requests grew 305% across Cloudflare from May 2024 to May 2025; Common Crawl is a nonprofit open corpus (300+ billion pages, 3–5 billion added monthly) that supplied 60% of GPT-3's training mix, and its CCBot crawler is controllable via robots.txt.

- **Links, Authority & Link Spam** — https://brass-seo.com/research/link-spam-authority
  Foundational link-authority research and Google's current link policies. Key facts: TrustRank (Gyöngyi, Garcia-Molina & Pedersen, VLDB 2004) propagates trust from a seed set of fewer than 200 human-vetted sites, so authority is proximity to trust rather than raw link count; the Web Spam Taxonomy (2005) named link farms and reciprocal-link schemes two decades before current enforcement; when SpamBrain neutralizes spammy links, any ranking benefit is lost and cannot be regained; Google can only crawl a link that is an anchor element with an href attribute; paid or exchanged links that pass credit must carry rel="nofollow" or rel="sponsored"; Google says most sites never need the disavow tool.

- **Search Spam Policies & Manipulation** — https://brass-seo.com/research/spam-policies-manipulation
  Google's spam policies and the 2024 enforcement updates. Key facts: the 2024 spam update added three abuse policies — scaled content abuse, site reputation abuse, and expired domain abuse — and the operative test for all three is intent to manipulate rankings plus low user value, not the tool or method used; Google expected the March 2024 update to reduce low-quality, unoriginal content by 40% (a later note reported about 45%); effective November 19, 2024, site reputation abuse applies regardless of first-party oversight of the third-party content; SpamBrain (launched 2018) detected 5x more spam sites in 2022 than 2021 and helps keep over 99% of searches spam-free.

- **AI Overviews & Zero-Click Search** — https://brass-seo.com/research/ai-overviews-zero-click
  Independent studies and Google's statements on AI Overviews and click behavior. Key facts: Pew Research (2025) found users clicked a result on 8% of visits when an AI summary appeared versus 15% without, and clicked a link inside the summary on just 1%; AI Overviews activated on 13.7% of queries overall but 64.7% of question-form queries (Xu, Iqbal & Montgomery, 2026); AI Overview exposure cut daily English Wikipedia article traffic by about 15% (Khosravi & Yoganarasimhan, 2026); AI Overviews expanded from 7 to 229 countries in 2024–2025 (Aral, Li & Zuo, MIT 2026); Google states AI Overview clicks are higher quality and total organic clicks have been relatively stable, a market-aggregate claim rather than a per-site guarantee.
