Why One Strategy Is No Longer Enough All Channels
Until recently, SEO meant one thing: satisfy Google's crawl and ranking systems. That logic held when Google was the only engine that mattered. It no longer is.
Today, a brand's search visibility is determined across three distinct surfaces. Google's traditional results remain important, but Google AI Overviews now appear at the top of millions of queries, pulling content from pages that meet specific structural criteria. Simultaneously, tools like ChatGPT, Perplexity, and Gemini are generating answers that cite sources — and those citations follow identifiable patterns around content structure, attribution, and originality.
SEO, GEO, and AEO share a foundation but diverge in what they optimize for. SEO rewards technical hygiene and link authority. GEO rewards verifiable original claims with named sources. AEO rewards direct, declarative answers in a specific structural position and length. A page can pass two of three and still be invisible on the third surface.

SEO: The Foundation Everything Else Sits On SEO
Google's crawl-and-rank systems remain the prerequisite. A page that can't be indexed can't be cited. Core Web Vitals — LCP under 2.5 seconds, INP under 200 milliseconds, CLS under 0.1 — are confirmed thresholds from Google Search Central, assessed at the 75th percentile of real user data. They function as ranking tiebreakers, not primary signals.
Title tag guidance is more nuanced than most SEO content acknowledges. Research by John McAlpin found Google rewrote 76.04% of title tags in Q1 2025, up from 61% in 2023. The practical implication: optimize for the user and keep your primary keyword near the front, but don't treat character count as a hard rule. Google reads the full HTML tag for ranking purposes regardless of what it displays.
The meta description is not a ranking factor. Google Search Central documentation is explicit. Its value is indirect: a well-written description increases CTR, and CTR is a behavioral signal that can influence rankings over time. Write it for the human, not the algorithm.
GEO: What Makes Large Language Models Cite You GEO
Generative Engine Optimization operates on a different logic than traditional SEO. LLMs don't rank pages — they cite sources when generating answers. Research published in the original GEO framework paper (Aggarwal et al., 2024) identified that content with named statistics and source attribution, original research, and clear author credentials is cited significantly more frequently than content that re-aggregates common knowledge.
The structural implication is direct: every H2 section should be independently answerable. An H2 that requires surrounding page context is a weaker citation candidate than one that stands alone. This is inference regarding specific RAG chunk behavior — the content principle itself is documented GEO best practice.
LLMs cite only 2–7 domains on average per response, according to analysis by Profound (2025). The competition for LLM citation is narrower than the competition for a Google top-10 ranking. Content that is structurally extractable, verifiably sourced, and demonstrably original wins citation share disproportionately.
AEO: Structuring Content for Direct AI Extraction AEO
Answer Engine Optimization is an extension of SEO applied to extraction behavior. The core mechanism: AI Overviews, featured snippets, and voice search results all favor content that answers a question directly within 40–60 words. This length is documented across multiple AEO research sources as the extraction sweet spot — long enough to provide context, short enough to be extracted as a unit.
The structural pattern is answer-first architecture: H1 as a question → direct answer paragraph (40–60 words) → supporting body content → FAQ block with JSON-LD schema. The September 2025 update to Google's Search Quality Rater Guidelines added explicit AI Overview evaluation criteria — the same signals that govern featured snippet selection now apply to the newer surface.
