Both AI Overviews and featured snippets appear at the top of Google search results—but they work in fundamentally different ways. Understanding these differences determines whether your optimization strategy succeeds in 2026's AI-driven search landscape.
Here's what separates these two SERP features and how to optimize for each.
According to SEO Sherpa's analysis of AI Overviews, a featured snippet is a direct excerpt from a single page, usually shown as a paragraph, list, or table. It quotes one source verbatim and includes a link back to that page.
Featured snippet characteristics:
Featured snippets act as previews. Users see part of the answer, then click through for the full context. The cited page receives significant traffic because the snippet demonstrates authority on the topic.
According to ALM Corp's Semrush AI Overviews study, AI Overviews are AI-generated summaries that appear at the top of Google search results, providing instant answers by synthesizing information from multiple web sources.
AI Overview characteristics:
Unlike featured snippets, AI Overviews don't quote any single source. Google's large language models (Gemini, PaLM2) digest content from numerous authoritative sources and generate a new, comprehensive response.
| Feature | Featured Snippet | AI Overview |
|---|---|---|
| Content source | Single webpage | 3-10+ websites |
| Content type | Direct extraction | AI-synthesized |
| Length | 2-4 sentences | Multiple paragraphs |
| Citations | One prominent link | Multiple small icons/cards |
| Behavior | Static | Dynamic, context-dependent |
| Click-through | Often drives clicks | Often satisfies without clicks |
According to ALM Corp's research, featured snippets and AI Overviews rarely appear together. Semrush data shows co-occurrence dropped from 34% in March to just 18% by November 2025.
This pattern suggests Google views AI Overviews as a replacement for featured snippets rather than a complementary feature. As AI Overview coverage expands, featured snippet opportunities are declining proportionally.
According to Medium's Serpstat analysis, AI Overviews are already nearly three times larger than featured snippets. By late 2025, Google largely stopped showing them together.
The two features affect user behavior differently.
Featured snippets drive clicks: According to Search Engine Land's zero-click analysis, when Google pulls an answer verbatim into a featured snippet, the cited source usually experiences a significant increase in clicks. Featured snippets have long been irresistible to searchers—who often click through to read more.
AI Overviews reduce clicks: According to The Egg's research, a meta-study analyzing the impact of AI Overviews revealed an average decline of 40% in click-through rate. Users get comprehensive answers without needing to visit websites.
According to NoGood's future of search analysis, 60% of searches now end without a click—between AI Overviews, featured snippets, and LLM responses providing answers directly in the SERP.
According to ClickRank's featured snippet research, featured snippets are the "seed data" for AI Overviews. If you win the featured snippet, you have a 75% higher chance of being the primary citation in the AI-generated summary.
This makes featured snippet optimization the most reliable path to AI Overview visibility. Content that ranks for position zero provides the foundation Google's AI uses when generating synthesized responses.
Featured snippet optimization focuses on clear, extractable answers:
According to SEO.com's AI search guide, taking the featured snippet approach—providing exact information quickly—increases your likelihood of citation in AI search results.
AI Overview optimization requires comprehensive, multi-faceted content:
According to RankHarvest's optimization guide, Google's AI favors unique, helpful content that satisfies user needs. Generic or shallow content will rarely be selected.
The answer: both, but differently.
Featured snippets provide a direct path to AI Overview citations. Winning position zero gives you 75% higher odds of primary citation status.
AI Overview optimization requires broader authority signals—backlinks, domain strength, comprehensive coverage, and freshness.
According to Maria Espie Vidal's analysis, featured snippets still rely on the cited page to complete user research, while AI Overviews provide what feels like a complete answer in one go.
AI Overviews and featured snippets serve different purposes in Google's search ecosystem:
Understanding these differences helps you allocate optimization efforts where they'll have the most impact on visibility and traffic.
