SEO to AEO: What’s Different and What’s Stayed the Same

Written by Rebecca Brosnan | November 5, 2025

Search has always evolved. Each shift brought a wave of anxiety, headlines about the “death of SEO,” and a scramble for the next big thing. AI search is the latest.

But here’s the truth: AEO doesn’t replace SEO. It expands it. 

The same fundamentals that drove organic success for decades still apply, but the mechanics of achieving them have shifted.

This guide explores how AEO and SEO are the same but different: how discovery, content, and influence evolve in an AI-first search landscape, and where enterprise brands should invest next to stay ahead.

The Core Shift: Where to Invest as SEO Evolves into AEO

AI search hasn’t rewritten what matters. It’s rewritten how it’s measured.

The question isn’t just “Can users find me?” It’s “Can AI engines understand, represent, and cite my brand accurately when users ask for insights?”

Let’s break down how that shift looks across three core investment pillars that define online visibility: Discovery (usability), Content (relevancy), and Influence (authority).

1. Discovery: From Crawlability to Comprehensibility

In traditional SEO, discovery meant ensuring search engines could crawl, index, and rank your pages. That hasn’t changed, but AI search introduces a new layer: understanding.

AI engines don’t just crawl; they interpret relationships between entities and concepts. Your site must still be technically sound, but also contextually clear.

Focus your investment on:

  • HTML crawlability: Ensure all critical content is accessible. Avoid JavaScript-only pages, as AI engines and crawlers can miss or misinterpret dynamically rendered text not present in the HTML source.
  • Structured feeds and APIs: When possible, supply content directly to search engines through accessible formats.
  • Entity clarity: Try implementing internal links, schema, and consistent naming for products and concepts on your site to potentially help AI connect related topics.

In the AI era, a crawlable site is the baseline. A comprehensible site is the differentiator.

2. Content: From Optimization to Depth and Usefulness

Traditional SEO rewards optimization: keywords, metadata, and on-page structure. AI search rewards usefulness: content that demonstrates expertise, depth, and full topic coverage.

AI search engines look for sources that teach and explain, not just mention, key topics.

Focus your investment on:

  • Net-new, comprehensive content: Go beyond refreshes to fill knowledge gaps with depth.
  • Structured and factual writing: Clear formatting, passage-level clarity, and verifiable facts help AI search engines interpret your content accurately.
  • Topical authority: Cover topics holistically across related pages to build recognizable expertise.

AI search engines favor brands that act like educators, not just content publishers.

3. Influence: From Backlinks to Brand Signals

Authority used to be measured in backlinks and domain metrics. In AEO, influence expands beyond links to include citations, mentions, and reputation across trusted online ecosystems.

AI engines surface sources that are discussed, referenced, and reviewed, not just linked.

Focus your investment on:

  • Third-party visibility: Earn mentions on credible industry sites, news outlets, and expert platforms.
  • Original research and data: Publish insights others will quote. AI models learn from frequently referenced sources.
  • Community and review engagement: Participate responsibly in discussion forums, collect reviews, and generate authentic brand signals.

You’re no longer just competing for Page 1, you’re competing to be part of the answer itself. And that’s the real opportunity: AI search removes the limits of traditional rankings, allowing your expertise to reach the right audience, where short, surface-level queries once couldn’t. 

When your content is credible, contextual, and authoritative, AI search can deliver your brand as the answer users are searching for.

The SEO → AEO Matrix: How Each Familiar Tactic Evolves

AI search doesn’t render SEO obsolete. It redefines what optimization looks like.

Every familiar tactic now has a new purpose: helping AI engines not just index your content, but interpret and trust it.

Here’s how the transition plays out across the key disciplines of enterprise SEO:

Tactic

Traditional SEO Actions

What’s Changing with AI Search

What To Do Now 

(AEO Actions)

Internal Linking

Built hierarchical link structures to guide crawlers and distribute PageRank.

AI search engines look for contextual depth, not just crawl paths. 

AI is trying to synthesize answers, so semantically linked content increases the odds your pages get pulled into an answer.

Map internal links around semantically related topics and entities to help AI understand relationships between concepts and themes.

Schema & Structured Data

Added different types of structured data to help search engines understand page content and earn rich results like stars, FAQs, or product details that increased SERP visibility.

AI may use structured data to understand entities and relationships, but it’s still uncertain the impact it may make to visibility in AI answers. It certainly can’t hurt.

While the influence of schema on AI search visibility is not yet clear, we suggest testing its implementation across all key content types. 

Competitor Analysis

Tracked ranking positions of known competitors in traditional Google SERPs.

AI search introduces new visibility layers. Some brands appear in AI summaries even if they don’t rank highly in SERPs.

Expand competitive analysis to include AI visibility: which competitors are mentioned or cited in AI results like Perplexity, AI Mode, or ChatGPT.

Content Creation

Optimized for keywords, search intent, and CTR with on-page SEO.

AI rewards content that is comprehensive, well-structured, factually grounded, and answers questions directly over keyword density. Intent-driven content becomes even more important.

Write for retrievability, not just ranking. Cover topics in depth, include data and expert attribution, and structure content so it’s easy for AI to parse and summarize—concise, clear, and factual.

Query / Keyword Research

Focused on search volume and keyword difficulty.

AI interprets user intent through questions and topics, not isolated keywords.

Research what AI engines summarize (the questions they answer) and prioritize content that fills those gaps. 

Think topic demand and prioritize prompts based and their “query fan out”, not just keyword demand.

Rank Tracking & Visibility

Monitored top web rankings and share of voice in organic SERPs.

Rankings are less linear. AI summaries take up a large amount of space at the top of the SERP within AI Overviews on Google, reducing clicks. 

Rankings are still at play because AI engines leverage search results to answer prompts.

Traditional rank tracking doesn’t tell the full story of SERP visibility anymore. 

Measure visibility not only in organic rankings but also in AI-generated overviews through tracking brand mentions and citations.

SEO Reporting

Primarily focused on traffic, rankings, and conversions.

AI search changes CTR patterns

Traffic may decline even with stable rankings due to AI answers satisfying queries directly.

Reframe KPIs to include citations and brand mentions in AI summaries. 

Track and report on visibility where users get answers, not just where they click.

Technical SEO

Ensured crawlability, canonicalization, and site speed for Googlebot.

AI still depends on crawlable, well-structured, and fast sites. 

Technical issues can prevent content from being found, accessed, or used by AI search engines.

Maintain technical best practices, but emphasize clarity: structured markup, consistent naming conventions, and accessible content formats. 

Content stuck in Javascript is not accessible.

SEO Testing & Experimentation

Tested metadata, UX changes, and on-page updates for impact on key SEO metrics.

Testing is no longer linear or formulaic.

AI search introduces new complexity: there’s no single “ranking,” traffic doesn’t tell the whole story, and visibility can’t yet be tracked with traditional tools.

Tests must focus on how content is interpreted, not just how it ranks or how much traffic it generates.

Until reliable measurement exists, focus on building clarity and consistency across content — the signals AI systems rely on most.

 

Conclusion: 

SEO and GEO share the same DNA; visibility built on relevance, authority, and usability.

What’s changed is the interface of discovery: AI search engines don’t just index and rank, they interpret, synthesize, and cite.

Winning now means ensuring your brand is not only findable, but understandable and reference-worthy in the world of AI-generated answers.
