This is something I've been paying a lot more attention to recently, especially with AI search tools like Google AI Overviews and Perplexity becoming more popular. Structured data has quietly become one of the most underused SEO techniques for most websites.
Simply put, structured data is a way of adding extra information to your website's code that helps search engines and AI tools clearly understand what your content is about. Instead of Google or an AI tool guessing what your page means, you're telling them directly.
The most visible impact I've seen is rich results in Google Search. When you add the right schema markup, your listing can show star ratings, FAQs, pricing, business hours, or product details directly in the search results. This makes your result stand out compared to plain blue links and usually improves click through rates noticeably.
For AI search specifically, structured data helps AI tools identify your brand as a credible entity. Organisation schema, LocalBusiness schema, and sameAs links that connect your website to your social profiles and directory listings all help AI platforms like ChatGPT and Perplexity recognise your business accurately. This is what reduces the chances of AI giving wrong or outdated information about your brand.
FAQ schema is one I always recommend implementing first. When your common questions and answers are marked up properly, Google AI Overviews and featured snippets are much more likely to pull directly from your content when someone asks a related question. It's one of the fastest ways to get visibility in AI generated answers without needing to build new backlinks.
For local businesses specifically, LocalBusiness schema is a must. It clearly communicates your name, address, phone number, opening hours, and service area to both Google and AI tools. Combined with a well optimised Google Business Profile it significantly strengthens your local search presence.
The honest truth is most websites still don't have proper structured data in place, which means there's a real opportunity right now for businesses that implement it correctly to stand out both in traditional search results and in AI powered answers before it becomes standard practice everywhere.
