AEO Strategy 2025: Keyword Analysis and Content Optimisation for First-Page Rankings

2025 marks a significant turning point for SEO. Google's AI Overview — AI-generated summaries appearing above organic results — and the Search Generative Experience have fundamentally changed how users receive answers. Effective SEO strategies in 2025 must adapt fully to this new ecosystem.

How SEO Has Changed in the AI Search Era of 2025

The most significant change is the increasing sophistication of search intent. Users now search with longer, more detailed conversational queries, and Google responds with AI Overview rather than traditional link lists. Appearing in AI Overview has become a new goal beyond ranking #1. Content cited in AI Overview typically comes from pages with high authority, clear information structure, and comprehensive answers within a single page.

Keyword Analysis Strategy for 2025

Keyword analysis in 2025 must extend beyond short-tail keywords to encompass long-tail and conversational queries that users ask AI Search. AI helps discover conversational variations, while tools like AlsoAsked, AnswerThePublic, and Google's People Also Ask reveal what users are genuinely asking.

Entity SEO is increasingly important — Google understands entities (people, places, things, concepts) more deeply than keywords alone. Content that comprehensively covers related entities helps Google recognise genuine expertise on the topic.

Optimising Content for AI Overview

To be cited in AI Overview, content must: answer questions directly in the first paragraph of each section, feature a clear structure with unambiguous headers, maintain high factual accuracy with credible source citations, and identify authors with explicit expertise. Schema Markup remains critical — particularly FAQPage, HowTo, Article, and LocalBusiness Schema — helping Google's AI process content accurately and increasing Rich Result eligibility.

Technical SEO Essentials in 2025

Critical Technical SEO requirements in 2025 include Core Web Vitals (LCP, INP, and CLS threshold compliance), genuine Mobile-first experiences beyond merely responsive design, HTTPS as a baseline requirement, and Page Experience signals including non-intrusive ad placement.

Link Building in the AI Era

Link building remains important but quality now decisively outweighs quantity. AI analyses competitor link profiles and identifies high-value link building opportunities. Highest-value link types in 2025 include editorial links from local media (for local businesses), academic and government links, expert roundup features, and digital PR links.

Key Takeaways

• AI Overview shifts the SEO goal from ranking #1 to being cited in AI-generated answers
• Long-tail and conversational queries are significantly more important in 2025 and require comprehensive analysis
• Entity SEO and topical authority matter more than keyword density for Google to recognise expertise
• Schema Markup helps Google's AI process content more effectively and increases Rich Results eligibility
• High-quality link building from relevant sources remains a strong ranking signal in 2025

FAQ

Q: Does AI Overview reduce organic traffic?
A: Some informational queries are likely to see reduced traffic as Google answers them directly in AI Overview. However, transactional and commercial queries continue to drive clicks. Optimising for both Rank #1 and AI Overview citations is therefore essential.

Q: How does conversational SEO differ from voice SEO?
A: Conversational SEO covers all natural language queries used in text search. Voice SEO focuses specifically on spoken queries, which tend to be shorter and more location- or immediacy-focused. The two overlap significantly in practice.

Q: Should Thai businesses prioritise Google or other platforms like TikTok Search?
A: Google remains Thailand's primary search engine and should be prioritised first. However, TikTok Search and YouTube Search are gaining popularity among Gen Z and Millennials for how-to and product discovery content. A long-term SEO plan should account for all major platforms.
