In 2025, SEO is no longer just about ranking—it’s about visibility across AI platforms, chatbots, and answer engines. With Google’s AI Overviews appearing in 33% of searches and click-through rates dropping across the board, case studies have become more valuable than ever. Not only do they showcase real-world expertise, they can also earn citations in AI responses and help build the brand authority search engines now prioritise.

Why Case Studies Still Matter in 2025

  • Demonstrate E‑E‑A‑T: Share expert-driven, measurable, and trustworthy results.
  • Support AI citations: Create structured, referenced content that AI models can cite in summaries or voice results.
  • Build brand awareness: Secure your brand’s presence across both SERPs and chatbots.

How to Structure Case Studies for AI Visibility

1. Start with E‑E‑A‑T Foundations

Use named authors, include quotes or testimonials, and show clear before-and-after results. Add third-party references where possible.

2. Align with AEO & GEO Standards

  • Include an FAQ section to boost Answer Engine Optimisation (AEO).
  • Use llms.txt and metadata for Generative Engine Optimisation (GEO).
  • Keep content clear, conversational, and easy to summarise for AI tools.

3. Include Tangible Results

Document performance: keyword rankings, traffic growth, dwell time, backlinks gained. This data proves ROI and enhances trust signals.

4. Blend Traditional and AI-Focused SEO

Use internal linking, technical audits, and keyword mapping, but now consider things like token efficiency, AI-friendly structure, and prompt relevance.

SEO and AI Integration: Why This Works

Brands are now tracking how often their content appears in ChatGPT, Perplexity, and other platforms. Structured case studies give these models something valuable to quote—especially when wrapped in clean schema and metadata. They also perform better in Google’s AI Overviews, which favour real-world expertise over abstract how-tos.

  • Client context and the problem to solve
  • Strategy steps with tools used
  • AI-friendly formatting: questions, bullet points, conversational style
