# SERP

> Search Engine Results Page — the traditional list of ranked links returned by a search engine, now being supplemented by AI-generated answers.

**SERP** (Search Engine Results Page) is the list of results returned by a traditional search engine — typically 10 blue links ranked by algorithmic relevance. SERPs have been the primary competitive surface for [SEO](/concepts/foundations/geo-vs-seo) since the late 1990s. AI-generated answers are now supplementing (and in some use cases replacing) SERPs as the first touchpoint in customer discovery.

## Why it matters

Understanding SERPs is important context for [AEO/GEO](/glossary/geo) because the two competitive surfaces have fundamentally different dynamics. A SERP has room for 10 organic results; a typical AI answer mentions 3-5 brands. A SERP click goes directly to the source page; an AI mention may or may not include a [citation](/glossary/citation) link. The transition from SERP-based discovery to AI-answer-based discovery is what makes GEO a distinct discipline rather than an extension of SEO.

## How it applies in practice

Cited does not track SERPs directly — that is the domain of traditional SEO tools like Ahrefs, Semrush, and Google Search Console. Cited tracks the AI answer layer that sits alongside or above SERPs. The relationship between SERP ranking and AI visibility varies by platform: [Gemini](/concepts/platforms/how-gemini-search-works) draws from Google's search index (making SERP ranking more predictive), while [Perplexity](/concepts/platforms/how-perplexity-ranks-sources) uses independent retrieval.
