AEO & GEO
SEO vs AEO: what changes, what stays
SEO and AEO share the same foundation but target different outcomes. Here is what stays, what shifts, and the order that makes sense for most teams.
TL;DR
- SEO makes your content visible in Google and Bing results. AEO makes your content extractable and citeable by AI tools that generate answers directly.
- What stays the same: crawlability, indexation, page speed, quality content, and internal linking. These are prerequisites for both.
- What changes: content structure (answer-first), schema markup (more detailed), measurement (AI tools alongside traditional SERPs), and authority signals (entity verification).
- If your SEO is solid, add AEO on top. If your SEO has gaps, fix those first. AEO amplifies what works; it does not replace a weak foundation.
What SEO covers
SEO is the established foundation.
SEO has been the standard for web visibility since the late 1990s. Its core practices are well-documented, widely understood, and proven to drive organic traffic: keyword research, on-page optimisation, link building, technical health, and content quality.
Google processes over 8.5 billion searches per day. For most B2B companies in Germany, organic search remains the largest source of qualified traffic. SEO fundamentals are not optional; they are the baseline.
The technical side of SEO, crawlability and indexation, is also the entry point for AI search. If Google cannot crawl your page, ChatGPT cannot cite it. If Bing cannot index it, Copilot cannot reference it.
SEO also covers content quality, which matters for AI citation. Pages with clear structure, specific claims, and verifiable evidence perform well in both traditional search and AI tools. When you need that foundation owned commercially, start with our organic search programme.
What AEO adds
AEO is the new layer on top.
AEO takes the SEO foundation and adds specific practices for AI search tools. The goal shifts from ranking in a list to being cited in a generated answer. This requires changes to content structure, schema, measurement, and authority building.
Content structure changes from introduction-first to answer-first. Traditional SEO allowed 200-word introductions before the main point. AEO requires the answer in the first one or two sentences because that is what AI tools extract.
Schema markup becomes more detailed. SEO used basic schema for rich results. AEO adds Organization, author, date, and content-type labels that AI tools use for source verification and attribution.
Measurement expands. SEO measures rankings, click-through rates, and organic traffic. AEO adds AI tool presence, citation tracking, and referral monitoring from AI-powered platforms.
Side by side
Six aspects, compared directly.
01
Goal
SEO: Rank in search result lists. AEO: Be cited in AI-generated answers. Both aim for visibility, but the output format is different.
02
Content format
SEO: Introduction, then detail, then conclusion. AEO: Answer in the first paragraph, then evidence and context below. AEO is a subset of SEO content quality.
03
Schema markup
SEO: Basic Article and FAQ schema for rich results. AEO: Detailed Article, Organization, author, date, and breadcrumb labels for AI source verification.
04
Measurement
SEO: Rankings, CTR, organic sessions. AEO: AI tool presence, citation frequency, referral traffic from AI platforms. AEO measurement supplements SEO measurement.
05
Authority signals
SEO: Backlinks, domain authority, content relevance. AEO: Entity verification, consistent publisher identity, external mentions that AI tools can cross-reference.
06
Technical requirements
SEO: Crawlability, indexation, page speed, mobile friendliness. AEO: All of the above, plus IndexNow for Bing freshness, clean HTML for AI parsing, and fast extraction.

Transition plan
How to add AEO to your existing SEO work.
✓
Verify your SEO foundation is solid: crawlability, indexation, page speed, and mobile usability all pass.
✓
Audit your top 10 pages for answer-first structure. Rewrite the first paragraph to answer the target question in under 60 words.
✓
Add or improve Article, Organization, and BreadcrumbList schema on all key pages.
✓
Enable FAQPage schema on pages with genuine visible FAQ content.
✓
Set up Bing Webmaster Tools and check AI Performance reports monthly.
✓
Test your top 5 buyer questions in ChatGPT and Perplexity weekly. Record which sources appear.
✓
Add IndexNow to your publishing workflow for faster Bing indexing.
✓
Build one topic cluster of 4 to 6 pages around your primary service to establish topical authority.
Common questions
What teams ask about the SEO-to-AEO transition.
Do I need to stop doing SEO to focus on AEO?
No. AEO builds on SEO, it does not replace it. If you stop doing SEO, your crawlability, indexation, and rankings will deteriorate, which undermines your AEO efforts. The right approach is to add AEO practices on top of your existing SEO work.
Which should I prioritise if I can only do one?
If your technical SEO has significant gaps (slow pages, indexing issues, no mobile optimisation), fix those first. If your SEO is solid and you are already ranking well, adding AEO practices gives you access to the growing AI search channel.
How long does it take to see results from AEO compared to SEO?
Traditional SEO changes typically take 4 to 8 weeks to affect rankings. AEO changes to content structure can show impact in AI tools within 6 to 12 weeks, measured by citation pattern shifts. Schema improvements can show faster results, within 2 to 4 weeks, for features like rich results.
