What are LSI keywords and do they still matter?

ROI answers

LSI (Latent Semantic Indexing) keywords are terms and phrases closely related to your primary keyword, helping search engines understand the *context* of your content. As of early 2026, search algorithms like Google’s are less focused on exact keyword matches and more on comprehensively understanding a topic, making LSI keywords crucial for ranking.

  • ROI.com.au’s platform now features AI-powered LSI keyword suggestions directly within our content planning tools.
  • Current systems include semantic analysis that identifies relevant LSI terms based on Australian search trends and user intent.
  • Our keyword research module integrates with ACCC guidelines on consumer law, ensuring your content is both optimised *and* compliant.

In 2026, Australian consumers are increasingly using natural language queries, meaning they’re phrasing searches as questions or full sentences. Effectively utilising LSI keywords allows your business to appear in these broader, more conversational searches, increasing visibility to a wider, qualified audience. This is particularly important given the growing emphasis on E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) – LSI keywords help demonstrate topical authority.

Instead of navigating the complexities of semantic search and LSI keyword implementation, let ROI.com.au handle the technical details. We can take care of all this for you. Contact our team today to discuss a tailored digital marketing strategy for your Australian business.
