SERP
A SERP is the full results page a search engine returns after a user submits a query. It combines algorithmically ranked organic listings, advertiser-bid paid ads, and a range of SERP features such as AI Overviews and featured snippets.
- A SERP is the entire results page a search engine returns when a user enters a query.
- The page is built on three pillars: organic (natural) results, paid ads, and a variety of SERP features.
- It has evolved from a simple list of ten blue links into a page packed with rich elements like AI Overviews, featured snippets, and People Also Ask.
- Per Semrush data, only 1.53% of results show no SERP feature at all, making a pure list of links a rarity.
- A SERP refers to the whole page, which is a broader scope than the individual SERP features it contains.
Overview
A SERP (Search Engine Results Page) is the entire results page a search engine returns when a user enters a query. The full list that appears after you type a keyword into Google.com is the SERP itself. A single page brings together organic results that the algorithm ranks by relevance, paid ads served when advertisers bid on a keyword, and a range of SERP features that surface answers directly.
One distinction matters here. SERP features are individual elements placed within the results page, while the SERP is the whole page that holds all of them. In other words, the SERP is the larger container, and SERP features are the components inside it.
Components
A SERP is typically built on three pillars.
- Organic results: "earned" listings that the search engine's algorithm surfaces naturally by weighing signals such as content quality, relevance, expertise, trustworthiness, and backlinks. The traditional blue links fall into this category.
- Paid results: listings shown when advertisers bid on a keyword through platforms like Google Ads, marked with an "Ad" label. Backlinko's analysis found that roughly 51.61% of first-page SERPs display ads, with an average of 3.10 ads per page.
- SERP features: distinct elements set apart from traditional organic links that improve the user experience by delivering answers or supporting information directly on the page. These include AI Overviews, featured snippets, People Also Ask, knowledge panels, local packs, image packs, and video carousels.
Evolution
For a long time, search results were simply a list of ten organic links, the so-called "ten blue links." As search engines increasingly filled the results page with richer features, however, users now often get their answer directly on the page without ever clicking through.
Real-world data illustrates this shift. According to Semrush sensor data (October 2024), only 1.53% of search results contained no SERP feature whatsoever. Backlinko's analysis found People Also Ask appearing on roughly 58% of SERPs, direct answers on 18%, and featured snippets on about 12%. The biggest trend is the rise of AI Overviews: AI-generated summaries pulled from top-ranking pages now appear above every other result, claiming the prime position at the top of the search page.
SEO Implications
As the SERP has shifted from a simple list of links to a multi-layered page, ranking first alone no longer guarantees clicks. When top elements like AI Overviews or featured snippets appear first, more users get their answer on the page and leave. Search optimization today must therefore account not only for organic rankings but also for which SERP features a page can appear in and whether its content gets cited or included within those elements.
