How to Optimise Your Website for Google Gemini

Understanding Google Gemini and AI Overviews

Google Gemini is the AI model that now powers AI Overviews, the synthesised answer blocks that appear at the top of Google search results. When a user asks a question, Gemini analyses multiple web sources, synthesises an answer, and displays it with citations to the original pages. For businesses, being cited in an AI Overview is the new equivalent of ranking in position one.

Gemini doesn't simply index keywords. It builds a semantic understanding of your content including its meaning, structure, relationships to other topics, and the authority of your source. This means the optimisation strategies that worked for traditional Google rankings need to be supplemented with new approaches tailored to how Gemini processes information.

How Gemini Selects Sources for AI Overviews

Google has confirmed that AI Overviews prioritise sources based on several factors:

• Content quality and depth: Gemini favours comprehensive, expert-level content that thoroughly addresses a topic.
• Structural clarity: Pages with clear heading hierarchies, semantic HTML, and well-organised sections are easier for AI to parse and cite.
• Structured data: JSON-LD schema markup gives Gemini explicit, machine-readable facts about your page content.
• Source authority: E-E-A-T signals (Experience, Expertise, Authoritativeness, Trustworthiness) influence whether Gemini considers your site a credible source.
• Freshness: Up-to-date content with recent publication dates is preferred for rapidly evolving topics.

Practical Optimisation Strategies

1. Implement Comprehensive Structured Data

Structured data is the single most effective way to communicate with Gemini. At minimum, every business website should include:

• Organization and LocalBusiness schema on your homepage
• BlogPosting or Article schema on every content page
• FAQPage schema on pages with question-answer content
• BreadcrumbList schema for clear site navigation
• Service schema on your service pages

Seamróg Tech implements all of these schemas automatically through our Next.js build system, ensuring every page ships with complete structured data without manual configuration.

2. Use Semantic HTML Throughout

Gemini's natural language processing benefits enormously from semantic HTML. Replace generic containers with meaningful elements:

• <article> for self-contained content
• <section> for thematic groupings within a page
• <nav> for navigation blocks
• <header> and <footer> for page-level structure
• <dl>, <dt>, <dd> for definitions and key-value information

These elements provide Gemini with a structural map of your content, making it far more likely to extract and cite specific information accurately.

3. Write for Direct Answer Extraction

Gemini excels at extracting concise answers from well-structured content. For each topic you cover:

• Open with a clear, one-sentence definition or answer
• Follow with supporting detail and context
• Use question-format headings where natural (e.g., "What is X?" or "How does Y work?")

This pattern mirrors how Generative Engine Optimization (GEO) works in practice: structuring content for AI extraction rather than just human readability.

4. Build Entity Authority

Gemini connects information through entities such as recognisable people, organisations, places, and concepts. Strengthen your entity presence by doing the following:

• Maintaining consistent business information (name, address, description) across your website, Google Business Profile, and social media
• Using Organization schema with sameAs links to your LinkedIn, Twitter/X, and industry profiles
• Creating author pages or bios that establish the expertise of your content creators
• Earning mentions and citations from other authoritative sources in your industry

5. Optimise Technical Performance

Gemini inherits Google's existing quality signals, meaning Core Web Vitals and page performance still matter:

Largest Contentful Paint (LCP)

Target under 2.5 seconds. Server-side rendering with Next.js achieves this consistently.

Interaction to Next Paint (INP)

Target under 200ms. Minimise client-side JavaScript and hydration overhead.

Cumulative Layout Shift (CLS)

Target under 0.1. Reserve space for images and dynamic content to prevent layout shifts.

Frequently Asked Questions

Do AI Overviews reduce website traffic?

For informational queries, some click-through reduction occurs because users get answers directly. However, being cited in an AI Overview drives significant authority-based traffic, because users who click through from AI citations tend to be more engaged and conversion-ready.

Can I opt out of AI Overviews?

Technically, you can use the nosnippet meta tag, but this also removes you from regular featured snippets. For most businesses, the visibility benefit of appearing in AI Overviews far outweighs the cost.

How does Gemini differ from ChatGPT for search?

Gemini is integrated directly into Google Search, giving it access to Google's full index and real-time crawling. ChatGPT relies on Bing's index and periodic browsing. Both benefit from the same foundational optimisation such as semantic HTML and structured data, but Gemini's integration with Google makes it the higher-priority target for most businesses.
