What is Google AI Overviews and how does it work in 2026?.

The evolution of SERPs with generative AI

Google AI Overviews (AIO) is a result format that displays an AI-generated answer at the top of search, based on multiple web sources. In 2026, AIO covers 35% of queries in Spain, according to Statista. The system selects snippets from pages with high authority, structured content, and rich data. It prioritizes clear, cited, and up-to-date answers. Unlike traditional featured snippets, AIO can combine information from several sites, so optimization must be holistic.

Rich data and direct answer format

Structured content is essential for Google AI to understand and extract your information. The most effective techniques include: use of numbered lists, tables, clear definitions, and FAQs with FAQ schema. According to a Think with Google study, pages with structured data are 40% more likely to appear in AIO.

ChatGPT ranking

So ChatGPT, Gemini, Perplexity and Google AI Overview recommend your company when a customer asks “who’s the best in Valencia” — from €490 a month.

Ranking inside AI models works differently from classic SEO: what matters is how facts about your company are structured, how quotable they are, and whether you show up in the sources the models read. Every month we check what ChatGPT, Gemini and Perplexity say about you and fix whatever keeps you out of the answer. The field is young, so we work on subscription: models keep changing and a set-it-once setup doesn’t hold here. In Spain these services run €1,500–5,000 a month — we come in three times cheaper.
