As of early 2026, AI-powered search engines like Google’s Gemini and others *can* index JavaScript content, but it’s more complex than indexing standard HTML. Search engines now render JavaScript to understand the content it dynamically generates, meaning they execute the code to see what’s displayed to the user.
- Improved Rendering Capabilities: Current systems include significantly faster and more reliable JavaScript rendering, allowing for indexing of Single Page Applications (SPAs) and interactive elements.
- Core Web Vitals Focus: Search algorithms in 2026 heavily prioritise website speed and user experience, and poorly optimised JavaScript can negatively impact these metrics.
- Schema Markup Support: AI search engines now features enhanced understanding of structured data (Schema markup) within JavaScript, improving rich snippet display in search results.
This is particularly relevant for Australian businesses, as the ACCC continues to emphasise online competition and discoverability. A website reliant on JavaScript for crucial content *must* be technically sound to avoid being penalised by search algorithms. Furthermore, ensuring compliance with Australian Consumer Law regarding accurate product information displayed via JavaScript is vital.
