What keywords work best for AI search optimization?

ROI answers

As of early 2026, AI-powered search engines like Google’s Gemini and Bing AI prioritise ‘semantic’ keywords – phrases reflecting user *intent* rather than just isolated terms. Current systems include advanced natural language processing, meaning search algorithms understand the context and relationships between words, not just their presence on a page.

  • Long-Tail Keywords: Focus on highly specific phrases (e.g., “best coffee machine for small cafe Sydney” instead of just “coffee machine”).
  • Question Keywords: AI excels at answering questions. Keywords framed as questions (e.g., “how to optimise my website for mobile”) perform well.
  • Local Keywords: Include Australian-specific locations and terms (e.g., “plumber Melbourne”, “tradie insurance Brisbane”).
  • Intent-Based Keywords: Categorise keywords by user intent – informational, navigational, transactional, or commercial investigation.

In 2026, Australian businesses must also consider the evolving data privacy landscape with updated ACCC guidelines. Optimisation strategies now features a strong emphasis on ethical data usage and transparent keyword targeting. Furthermore, voice search, increasingly popular via smart speakers, favours conversational, long-tail keywords. The rise of AI-generated content also means originality and expertise are paramount; simply stuffing pages with keywords is heavily penalised.
