How SEO Is Changing in 2025
Search is no longer just about keywords and blue links. AI Overviews now appear in ~20% of Google queries, zero-click searches have surged to 69%, and AI-driven search tools like ChatGPT (400M weekly users), Perplexity AI, and Bing Copilot are gaining significant traction. Despite this, 76% of AI overview citations still come from pages ranked in the traditional top 10 — proving that SEO foundations remain critical.
The Rise of AI Overviews & Answer Engines
What Are AI Overviews?
AI Overviews (AIO) are Google's AI-generated summaries that pull data from authoritative pages. Google's "AI Mode" (mid-2025) can answer complex multimodal queries. AIO pushes traditional organic results down, lowering CTR. Brands should optimise for conversion quality, not just traffic volume.
Answer Engines: The New Frontier
Platforms like Perplexity AI and ChatGPT Search are shifting habits. To stay competitive, SEO must move beyond Google and consider generative search optimisation (GEO/AEO).
Traditional SEO vs. Entity SEO
What Is Entity SEO?
Entity SEO optimises for real-world entities (people, places, organisations, products) and their relationships — not just keywords. Google's Knowledge Graph now contains 54B+ entities and 1.6T facts. With ~60% of searches being zero-click, entity SEO ensures your brand is recognised and cited even without a click.
Implementing Entity SEO
- Entity Mapping — Identify 3–5 core entities per page
- Describe Relationships — Context matters: describe your brand's relationships clearly
- Structured Data (Schema) — Correct schema boosts rich snippets by 35%
- Entity Linking — Link to authority sources (Wikipedia, gov.sg, LinkedIn)
- Topic Clusters — Use internal linking to signal topical authority

- Mobile-first optimisation
- Schema markup for clarity
- Write conversational, Q&A-style content for LLMs
- Update regularly for freshness
- Highlight expert credentials and consistent brand messaging
