SERP features are the special result types that appear on a Search Engine Results Page beyond the traditional ten blue links. They include Featured Snippets, People Also Ask boxes, Knowledge Panels, Local Packs, image carousels, video results, news boxes, shopping results, and AI Overviews.

Key SERP Features

Featured Snippet: a boxed answer pulled from a page and displayed above organic results (position zero). Winning the snippet can dramatically increase visibility and click-through rate. People Also Ask (PAA): expandable questions related to the original query — each links to a different source. Knowledge Panel: an information box about an entity (person, company, place) drawn from Google's Knowledge Graph. Local Pack: map-based results for location-relevant queries. AI Overview: Google's AI-generated answer that appears at the top of results for qualifying queries.

Strategic Implications

SERP features have reduced click-through rates on traditional organic results. A page ranking #1 organically may get fewer clicks than it would have five years ago because the Featured Snippet, PAA, and AI Overview answer the query before the user scrolls to organic results. This is the "zero-click search" problem.

Optimization

Target Featured Snippets with concise, direct answers in paragraph, list, or table format. Target PAA with FAQ-structured content. Target Knowledge Panels with Knowledge Graph Optimization. Target AI Overviews with GEO.

The Convergence

SERP features and AI answers are converging. Google AI Overviews are a SERP feature powered by generative AI. Optimizing for SERP features is increasingly the same discipline as optimizing for AI retrieval — structured, authoritative, entity-rich content that directly answers the question.
