Structured data Google guide for better AI visibility

Why do some websites get stars, prices and answers directly in Google, while your site remains invisible? The secret lies in structured data, a simple piece of code that can increase your CTR by 35% without any extra advertising budget. Schema markup tells Google exactly what your pages contain, resulting in striking rich snippets that generate more clicks.

💡 Key takeaway: Structured data is the most underestimated SEO tactic of 2026 for Belgian SMEs who want to accelerate organic growth.

What is structured data?

Structured data is a standardised way of labelling information on your website so that search engines understand exactly what each page contains. This is done via schema markup according to Schema.org standards.

Google’s algorithm increasingly relies on structured data for accurate answers. According to research by Data World, AI systems with knowledge graphs achieve 300% higher accuracy than systems without structured data.

“Schema markup can increase the number of featured snippets by 677% and improve CTR by an average of 30%.”

— Danny Sullivan, Public Liaison for Search at Google

Why structured data is crucial in 2026

AI Overviews dominate search results

Google’s AI Overviews appear in 15% of all searches and use structured data as their primary source. Through zero-click search optimisation you position content for AI-generated answers.

Voice search explodes

35% of all searches happen via voice search in 2026. Voice traffic converts 3x better because users have more specific intent. LocalBusiness schema is essential for “near me” queries.

Visual search grows exponentially

Google Lens uses structured data for visual search results. Product schema with ImageObject markup opens new traffic channels beyond traditional text search.

E-E-A-T signals strengthen

Google’s E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is more strongly valued. Structured data strengthens these signals via Author markup, Organisation schema and Review aggregation.

Proven results in practice

E-commerce: Product schema

Shopify webshops see dramatic CTR improvements with Product schema. Stars and prices in search results immediately attract more clicks.

Result: 25-40% higher CTR for product pages

Local businesses: LocalBusiness schema

Address, opening hours and contact details are prominently displayed in local search results. Perfect for local SEO strategies.

Result: 30% more local visibility

Content sites: FAQ schema

FAQ markup ensures that answers appear directly in Google. This increases authority and combines perfectly with conversion optimisation.

Result: 35% more featured snippet appearances

“Rich results attract more attention and can significantly increase organic CTR, even without higher rankings.”

— John Mueller, Search Advocate at Google
