Standard Definition
AI Overviews is a Google Search function in which a generative AI algorithm produces a summarizing answer based on web content and displays it above the classical search results list. The function was rolled out for US users in May 2024 and for German-language users in March 2025 — previously known as „Search Generative Experience" (SGE) in experimental status. Sources are linked in a list under or beside the answer — since May 2026 increasingly also as inline links directly at the relevant text fragment. AI Overviews appear preferentially for informational search queries, less often for transactional or navigational queries. Triggering happens algorithmically based on search intent classification.
What this means in mandate practice
Three observations from mandate practice since the AI Overviews rollout are strategically central.
First, click volume from classical organic top positions has declined significantly in many informational topics since introduction — depending on industry and query type between 8 and 35 percent. The Pew Research study from July 2025 documents 8 percent average click-through rate decline; Ahrefs measures 34.5 percent CTR loss at top rankings with AI Overviews. Pure information pages without conversion paths are most affected; transactional pages (product pages, service offerings) less so.
Second, source selection strongly favors established domains. New sites need 6 to 12 months of continuous substantial content production before they are regularly cited in AI Overviews. Those with a new domain hoping for AI visibility must think in waiting times and substance investment — not in quarterly successes.
Third, pillar content with own substance is structurally treated differently than aggregating standard content. Substance content more often lands in the „new perspectives" slot with its own prominent link; aggregation content lands without prominent linking in the summary itself. Those planning SEO strategy for 2026 must treat AI Overviews as an independent visibility axis next to classical search — not as a side phenomenon that classical SEO measures would cover by association.
