The four types of SERP feature, grouped by function
Not every SERP feature does the same job on the results page, and grouping them by function helps more than memorizing a loose list of names. In practice they fall into four types, though some individual cases don't fit neatly into just one, and several can show up together on the same search.
Informational features. These answer the user's question directly, without requiring a click to any page. The featured snippet pulls a paragraph, a list, or a table from an already-indexed page and places it at position zero. The Knowledge Panel shows already-verified facts about a known entity (a person, a company, a place), usually drawn from Google's own databases rather than from one particular site's content. People Also Ask adds related questions, each with a short answer pulled from a different page.
Local features. These show up when Google detects local intent in a search, whether explicit ("dentist in Austin") or implicit ("near me"). The Local Pack, with three business listings and a map, is the most visible example. It's built from the business's Google Business profile, not from the content or links of its website, so a business with a mediocre site can still appear if its profile is complete and carries good reviews.
Visual features. These prioritize format over a direct text answer: the image carousel, the video carousel, and Shopping results are the most common. They don't always cut into clicks on the organic result, because the user often needs to compare several options before deciding which one to open, unlike an answer that already resolves the question inside the SERP itself.
AI-generated features. These synthesize content from several pages at once, not just one, and present it as a written passage with reference links alongside the text. The AI Overview is the main case in classic Google search; AI Mode extends the same logic into a full conversational format. Unlike the featured snippet, which copies a page excerpt word for word, the AI Overview generates new text drawn from several combined sources.
This grouping isn't an official Google taxonomy, it's a practical way to decide which SERP feature is worth chasing depending on the type of business and search: an ecommerce site depends more on visual features and Shopping, a local business depends on the Local Pack, and an informational site depends mostly on featured snippets and on getting cited inside the AI Overview.
