Search is changing. People still use Google, but they increasingly ask complete questions to AI assistants, search summaries and answer engines rather than browsing a list of blue links.

This has introduced a new collection of terms: SEO, AEO and GEO. The labels can be confusing, but the underlying goal is straightforward: make your expertise easy for both people and machines to understand.

SEO: Search Engine Optimisation

Traditional SEO improves a website's ability to be discovered through search engines. It includes technical performance, crawlability, keywords, useful content, links, metadata and site structure.

SEO remains foundational. AI discovery does not make technically inaccessible or poorly structured content more useful.

AEO: Answer Engine Optimisation

AEO focuses on making content suitable for direct answers. Clear questions, concise explanations, descriptive headings, definitions and structured information help search systems identify relevant passages.

GEO: Generative Engine Optimisation

GEO is commonly used to describe optimisation for generative AI experiences. The emphasis is less on ranking a page for one keyword and more on becoming a useful, credible source that AI systems can understand and potentially reference.

What should businesses actually do?

Start with genuinely useful content. Answer the questions customers ask before they contact you. Explain your process, pricing factors, trade-offs, terminology and expertise in language that is specific rather than generic.

Build topic relationships

A collection of isolated blog posts is less useful than a connected body of knowledge. An article about website redesign cost can link to redesign planning, CMS selection, UX and relevant case studies.

This is the same principle behind content-led platforms such as our mReferral project, where comparison tools, calculators and in-depth articles work together to support discovery and decision-making.

Use evidence

Original case studies, first-hand experience, data, examples and clear authorship make content more credible. Avoid producing dozens of interchangeable AI-written articles that add nothing new.

Structure pages clearly

Use meaningful headings, descriptive titles, sensible URLs and internal links. Make the main answer visible rather than burying it beneath a long introduction written only for keywords.

SEO is evolving, not disappearing

The terminology will continue to change. The durable strategy is to publish useful, structured, credible information around the problems your organisation genuinely understands.

Design for humans first, but make that knowledge easy for machines to interpret. That approach serves SEO, AEO and GEO at the same time.

搜尋方式正在改變。大家仍然使用 Google，但愈來愈多人直接向 AI Assistant、Search Summary 或 Answer Engine 提出完整問題，而不是逐條瀏覽傳統搜尋結果。

因此出現了 SEO、AEO、GEO 等新名詞。名稱看似複雜，但核心其實很簡單：讓人及機器都更容易理解你的專業內容。

SEO：Search Engine Optimisation

傳統 SEO 的目標，是提升網站在搜尋引擎被發現的能力，包括 Technical Performance、Crawlability、Keyword、Useful Content、Link、Metadata 及 Site Structure。

SEO 仍然是基礎。AI Search 並不會令技術上難以存取或結構混亂的內容突然變得有價值。

AEO：Answer Engine Optimisation

AEO 著重令內容更適合被直接回答。清晰問題、簡潔解釋、描述性 Heading、Definition 及 Structured Information，都有助 Search System 找到最相關的答案。

GEO：Generative Engine Optimisation

GEO 通常用來形容針對 Generative AI Search 的優化。重點不只是某個 Keyword 排第幾，而是令網站成為 AI 系統能夠理解、信任及有機會引用的資料來源。

企業實際應該做甚麼？

先製作真正有用的內容。回答客戶在聯絡你之前最常問的問題，清楚解釋流程、價格因素、選擇上的 Trade-off、專業術語及實際經驗，而不是只寫 Generic SEO Copy。

建立 Topic Cluster

十篇互不相關的 Blog，價值通常不及一個互相連結的 Knowledge System。例如「網站改版價錢」可以自然連結到 Redesign Checklist、CMS 選擇、UX 及相關 Case Study。

這亦是我們 mReferral 項目的內容策略概念：比較工具、Calculator 及深度文章互相配合，同時支援搜尋、理解及決策。

加入真正 Evidence

Original Case Study、First-hand Experience、Data、Example 及清晰 Authorship 都能提升內容可信度。不要為 SEO 大量生產彼此相似、沒有新增價值的 AI Article。

讓頁面結構清晰

使用有意義的 Heading、描述性 Title、合理 URL 及 Internal Link。直接回答問題，不要為了 Keyword 而把答案埋在很長的 Introduction 後面。

SEO 正在進化，而不是消失

名詞仍會繼續改變，但長期有效的策略仍然是：圍繞企業真正擅長的問題，發布有用、結構清晰而可信的內容。

先為人設計，再讓機器容易理解。這種做法同時有利 SEO、AEO 及 GEO。
