As of early 2026, search engines heavily rely on multimodal AI to understand image content, going beyond just file names and alt text. Effective image SEO in 2026 centres on providing comprehensive contextual data to these AI systems, ensuring your visuals contribute positively to your website’s ranking in Australian search results.
- Automated Alt-Text Generation: Current systems include AI-powered alt-text suggestions within content management systems, but manual refinement for accuracy and keyword relevance remains crucial.
- WebP & AVIF Dominance: These next-generation image formats are now features standard across all major browsers, offering superior compression and quality – essential for Core Web Vitals.
- Structured Data Markup: Implementing schema markup specifically for images (e.g., `ImageObject`) provides detailed information to search engines about the image’s context and purpose.
- Visual Sitemap Submission: Google and Bing now prioritise indexing images submitted via dedicated visual sitemaps, improving discovery.
In 2026, Australian businesses must also consider the increasing importance of image accessibility for compliance with the Disability Discrimination Act. Optimised images aren’t just for search engines; they’re vital for inclusivity, ensuring all Australians can access your online content. Furthermore, image file sizes significantly impact mobile data usage, a key consideration given Australia’s relatively high data costs.
