In May 2023, Google launched AI Overviews (then called Search Generative Experience) — AI-generated summaries that appear above traditional search results for a growing proportion of queries. By 2026, AI Overviews appear for a significant share of informational and commercial queries in the UK, and other AI-powered search tools (ChatGPT, Perplexity, Gemini) are capturing an increasing share of search traffic.
This changes the SEO equation in a specific way: visibility now has two components. The first is traditional ranking — appearing in the blue-link results below the AI Overview. The second is citation — being referenced as a source within the AI-generated answer itself. A site can rank on page one and still be invisible to users who read the AI Overview and do not scroll to the organic results.
Generative Engine Optimisation (GEO) is the practice of optimising for both. It extends traditional SEO — it does not replace it — by adding a layer of content structuring designed to make pages more extractable, citable, and trustworthy for AI systems.
GEO vs Traditional SEO: What Changes, What Stays the Same
| Dimension | Traditional SEO | GEO Addition |
|---|---|---|
| Goal | Rank in blue-link results | Also be cited in AI-generated answers |
| Content structure | Keyword placement, heading hierarchy | Self-contained passages, clear claim structure |
| Authority signals | Backlinks, domain authority | Named author, topical authority, E-E-A-T signals |
| Entity coverage | Keyword variants and LSI terms | Named entity coverage, entity co-occurrence, EAV structure |
| Technical signals | Core Web Vitals, crawlability | Structured data (Article, FAQPage, Person), AI extractability |
| Measurement | Rankings, organic traffic | AI Overview impressions (GSC), citation tracking |
The Six GEO Signals That Matter Most
Ranked by observed impact on AI Overview citation eligibility.
Topical Authority
Why it matters
AI systems preferentially cite sources with established topical authority — sites that cover a topic comprehensively and consistently, not just individual pages with strong content.
What to do
Build a topical map that covers your subject area systematically. A single strong article is less likely to be cited than a site with 20 interconnected articles on the same topic.
Named Author with Credentials
Why it matters
AI Overviews and LLM-based search tools weight author credibility. A named author with verifiable expertise signals that the content is trustworthy enough to cite.
What to do
Implement Person schema on author pages. Include a visible byline with a brief credential statement on every article. Link to an About page that establishes the author's expertise.
Self-Contained Factual Passages
Why it matters
AI systems extract passages, not full articles. A passage that requires the surrounding context to make sense is harder to cite accurately than one that is self-contained.
What to do
Write paragraphs that stand alone — include the subject, claim, and any necessary qualifier in the same sentence or paragraph. Avoid 'as mentioned above' or 'see the previous section'.
Entity-Rich Context
Why it matters
Pages with strong entity coverage — naming relevant people, organisations, tools, and concepts — give AI systems the context they need to understand and accurately represent the content.
What to do
Conduct an entity gap analysis: which entities does Google associate with your target queries that are absent from your pages? Add them as genuinely relevant context, not keyword stuffing.
Clear Claim Structure
Why it matters
AI systems are better at extracting content that makes clear, direct claims rather than hedged, ambiguous, or overly qualified statements.
What to do
Lead with the claim, then provide context and qualification. 'LCP should be under 2.5 seconds for a Good rating' is more extractable than 'there are various thresholds for LCP depending on context'.
Structured Data
Why it matters
Schema markup helps AI systems understand the type and structure of content — whether a passage is a FAQ answer, a how-to step, or an article claim.
What to do
Implement FAQPage, Article, HowTo, and Person schema where appropriate. Ensure schema matches visible page content exactly.
The Traffic Implication: Zero-Click and Citation Traffic
AI Overviews introduce a new traffic dynamic: zero-click results. When a user's query is answered directly in the AI Overview, they may not click through to any source — even if your site is cited. This is a genuine challenge for informational content that previously drove top-of-funnel traffic.
However, the picture is more nuanced than "AI Overviews kill traffic". Research and early GSC data suggest that:
Sites cited in AI Overviews often see increased branded search and direct traffic — users who see the citation and then search for the brand directly.
Commercial and transactional queries are less affected by zero-click than informational queries — users researching a purchase still click through.
Being cited in AI Overviews for informational queries can build brand authority that converts later in the funnel, even without an immediate click.
The sites most at risk are those that rank for informational queries but have no clear conversion pathway — their traffic was always low-intent.
GEO for London SMEs: Where to Focus
For a London SME, the GEO opportunity is concentrated in a specific area: local and industry-specific queries where AI Overviews currently have lower coverage and where local authority signals (Google Business Profile, local citations, location-specific content) give local businesses a structural advantage over national competitors.
High GEO opportunity
- ·Industry-specific how-to guides
- ·Local service area explainers
- ·Comparison and decision guides
- ·FAQ-rich service pages
Lower GEO priority
- ·Highly competitive national informational queries
- ·Transactional pages (product/service pages)
- ·Brand-specific pages
- ·Pages with thin informational value
GEO and Semantic SEO: The Connection
GEO is not a separate discipline from semantic SEO — it is the natural endpoint of building genuine topical authority. The same signals that drive AI citation eligibility (entity coverage, topical depth, clear claim structure, named authorship) are the signals that semantic SEO has always optimised for.
Frequently Asked Questions
What is Generative Engine Optimisation (GEO)?
Generative Engine Optimisation (GEO) is the practice of structuring content so that it is cited, summarised, or referenced by AI-powered search features — primarily Google's AI Overviews, but also ChatGPT, Perplexity, and other LLM-based search tools. GEO extends traditional SEO to account for the fact that AI systems now synthesise answers from multiple sources rather than simply listing ranked pages.
Is GEO replacing traditional SEO?
No — GEO extends traditional SEO rather than replacing it. The foundational signals that drive traditional rankings (topical authority, E-E-A-T, technical health, backlinks) also drive AI citation eligibility. GEO adds a layer of content structuring — clear claims, entity-rich context, self-contained passages — on top of an already-strong SEO foundation.
How do I know if my site appears in AI Overviews?
Google Search Console now includes AI Overview impression data for sites that appear as sources. You can also manually search for queries relevant to your content and observe whether your site is cited. Third-party tools like SE Ranking and Semrush are adding AI Overview tracking features.
Does structured data help with GEO?
Yes — structured data (schema markup) helps AI systems understand the type and structure of your content, making it easier to extract and cite accurately. Article, FAQPage, HowTo, and Person schema are particularly relevant for GEO. However, structured data alone is insufficient — the underlying content must have strong entity coverage and clear factual structure.
