SERP stands for search engine results page. It is the page a search engine shows after you type a query. That is the whole meaning of the word. The useful part is what sits on the page now. A Google results page is no longer ten blue links. It can show ads, an AI answer, a boxed snippet, a list of questions, a map, products and videos before the first ordinary result. Each one changes who gets the click. This page names each part, says what Google documents about how it is chosen, and sets out what the click studies measured, with their limits.
If you just want to see your own page as a result, the free SERP preview tool shows your title and description laid out as Google displays them, on desktop and mobile. It shows what your page sends. Google may still rewrite it, for reasons covered below.
The figures are different kinds of evidence. Pew tracked the browsing of 900 US adults[21]. Ahrefs studied aggregated Search Console data for 300,000 keywords, on desktop, and calls its result a correlation[23]. SparkToro analysed a Similarweb web panel that leaves out app searches[24]. The element count is from a peer-reviewed catalogue[30].
What SERP means
Two details make the term less simple than it sounds. First, there is no single SERP for a query. Google says it uses “information such as your location, past Search history, and Search settings” to decide what is most relevant. Its own example: someone searching “football” in Chicago sees American football, and in London sees soccer[16]. So when someone says a page “ranks third”, the fair question is: for whom, where, and on which device?
Second, the page keeps growing. Researchers who studied two decades of archived Google results pages found that the well-known “10 blue links” list “has evolved into richer interfaces”, with “more features that provide direct answers”[29]. A 2026 study of six search engines (Google, Bing, Yandex, Yahoo!, Baidu and DuckDuckGo) catalogued 143 distinct elements. It sorted them into organic results, sponsored results and features[30].
SEO and SERP are often said together, and the link is simple. SEO is the work. The SERP is where the work shows up. What has changed is the number of places on one page where a site can appear, and how many of them sit above the first ordinary result.
The anatomy of a Google results page
Google’s own documentation names the parts. Its visual elements gallery splits a results page into text results, rich results, image results, video results and “exploration features” that help people refine a search[1]. Here is what you are likely to meet, roughly from the top. The order changes with the query, and most queries show only a few of these.
Ads
Text ads usually come first. Google says top ads “are generally above the top organic results”, but “may show below the top organic search results on certain queries”. Position comes from Ad Rank: the bid, ad quality, thresholds and the context of the search[11]. In October 2025, Google moved text ads under one “Sponsored results” label, with a button to hide them. Google says “you’ll still never see more than four text ads in a grouping”. The label can appear above or below AI Overviews and at the bottom of the page, and Shopping ads are labelled “Sponsored products”[12].
AI Overviews
An AI Overview is an “AI-generated snapshot with key information and links to dig deeper”. Google shows one “when our systems determine that generative AI can be especially helpful”[9]. It usually sits at the top, but not always: Ahrefs found “around 9% of AI Overviews appear outside position one”[23]. Google says AI Overviews and AI Mode may use a “query fan-out” technique, “issuing multiple related searches across subtopics and data sources” to build a response[6]. So the pages cited can come from searches other than the one you typed. The AI Overviews guide covers how pages get cited.
AI Mode
AI Mode is not a box on the results page. It is a separate tab. Google calls it its “most powerful AI search experience”, reached from the AI Mode tab on a results page, from google.com/ai, or from the Google app. It answers in conversation, with follow-up questions and links to the web. Google adds that “in some cases, AI Mode will provide a set of web links if there’s not high enough confidence”[10]. In AI Mode, then, the results page is mostly one answer. The AI Mode guide has the detail.
Organic results: title link, snippet and attribution
The ordinary result is still the core of the page. Google calls the clickable headline the title link: “the title of a search result on Google Search and other properties (for example, Google News) that links to the web page”[2]. Under it sits the snippet, “the description or summary part of the search result”[3]. Above it sits the attribution: favicon, site name, a readable URL and sometimes a breadcrumb. Some results also carry a byline date or extra lines Google calls rich attributes[1].
Sitelinks
Sitelinks are “links from the same domain that are clustered together under a text result”. Google says that “at the moment, sitelinks are automated”. You cannot add one by hand. You can only keep a page out of them by removing it or adding noindex[5].
Featured snippets
A featured snippet turns a normal result upside down. Google describes them as “special boxes where the format of a regular search result is reversed, showing the descriptive snippet first.” Asked how to get one, Google’s answer is “You can’t.” Its systems decide whether a page would make a good featured snippet for a search. You can opt out with nosnippet, data-nosnippet or a short max-snippet[4].
People Also Ask
Google’s documentation calls this box a related questions group: “a cluster of questions that are related to what the user initially searched for”[1]. In Search Console, a link inside it follows “standard position rules”[17]. Google publishes no criteria for which page answers each question. The People Also Ask guide covers what studies have found instead.
The local pack
For searches with local intent, Google shows a map and a short list of businesses from Google Business Profile. The SEO trade calls it the local pack. Google says “local results are mainly based on relevance, distance, and popularity”, where relevance “is how well a Business Profile matches what someone is searching for”. It is also blunt about money: “There’s no way to request or pay for a better local ranking on Google.”[13]
Knowledge panels
Knowledge panels are “information boxes that appear on Google when you search for entities (people, places, organizations, things) that are in the Knowledge Graph.” They “are automatically generated”, from “various sources across the web”. The subject of a panel, or its official representative, can claim it and suggest changes[14].
Images and videos
Images can appear inside text results, in Google Images and in Discover. Google finds them in the src of an <img> element, and says it “doesn’t index CSS images”[7]. Videos can appear in several places, “including the main search results page, Video mode, Google Images, and Discover”. To qualify, a video needs an indexed watch page, must be embedded and visible on it, and needs a valid thumbnail at a stable URL[8].
Products
Product results come from Google Merchant Center. With free listings, products “can appear at no cost on Google Search, Google Maps, Gemini, YouTube, the Shopping tab, Google Images, and Google Lens”[15]. Paid Shopping ads sit beside them under the “Sponsored products” label[12].
SERP features, and what wins each one
Most advice on SERP features is guesswork. This table only says what Google itself documents. Where Google publishes nothing, it says so.
| How it is chosen | What Google says helps | Your control | |
|---|---|---|---|
| Ads | Ad Rank auction | Bid, expected click-through rate, ad relevance, landing page experience | Paid placement |
| AI Overview | Automatic, when Google judges it helpful | Indexed and eligible for a snippet. No extra technical requirements | nosnippet, data-nosnippet, max-snippet, noindex |
| AI Mode | Automatic, in its own tab | The same requirements as AI Overviews | The same controls as AI Overviews |
| Title link | Automatic, from the title element, headings, og:title, link text and more | A descriptive, concise title element and one clear main title | Indirect: fix the inputs |
| Snippet | Automatic, mostly from page content | A unique meta description for each page | nosnippet, max-snippet, data-nosnippet |
| Sitelinks | Automatic | Clear structure, informative titles, concise internal link text | Remove a page with noindex |
| Featured snippet | Automatic. Asked how to mark a page as one, Google says "You can't" | Not documented beyond snippet eligibility | Opt out with snippet controls |
| People Also Ask | Automatic | Not documented | Not documented |
| Local pack | Relevance, distance and popularity | A verified, complete, up-to-date Business Profile | Cannot be bought |
| Knowledge panel | Automatic, from the Knowledge Graph | Not documented | Claim it and suggest changes |
| Images | Automatic | Descriptive alt text and useful content around the image | Use img elements: CSS images are not indexed |
| Videos | Automatic | Indexed watch page, visible video, stable thumbnail | Clip or SeekToAction markup for key moments |
| Product listings | Merchant Center product data | Complete product data, return policy, shipping settings | Opt in through Merchant Center |
Sources for the rows: ads[11], AI features[6], title links[2], snippets[3], sitelinks[5], featured snippets[4], local results[13], knowledge panels[14], images[7], videos[8] and free listings[15].
One pattern stands out. Almost everything is automatic, and the documented requirements are basic: be indexed, be eligible for a snippet, and describe the page clearly. For AI Overviews and AI Mode, Google says “there are no additional technical requirements”[6]. Anyone selling a secret markup for a feature is selling something Google does not describe.
How SERP features change clicks
Start with what the studies cannot show. Each one measures a different sample, by a different method, over a different period. None of them can see your queries. And Google disputes how they are read. With that said, they point the same way.
Pew Research Center (independent) tracked the browsing of 900 US adults in March 2025. When a Google search showed an AI summary, people clicked a traditional result in 8% of visits. Without one, they did in 15%. They clicked a link inside the summary in 1% of visits. And they ended their browsing session on 26% of pages with a summary, against 16% without[21].
Seer Interactive (a vendor, using its clients’ data) studied 3,119 search terms across 42 organisations. From June 2024 to September 2025, organic click-through rate on queries with an AI Overview fell from 1.76% to 0.61%, a 61% drop. Paid click-through rate on the same queries fell 68%. Queries without an AI Overview fell too, from 2.74% to 1.62%. Brands cited inside an AI Overview earned 35% higher organic click-through rate than brands that were not[22].
Ahrefs (a vendor) compared 300,000 keywords using aggregated Search Console data. In December 2025, the top result had a 58% lower average click-through rate when an AI Overview appeared. In its words: “For every 100 clicks you could historically earn for a top-ranking page, Google now ‘keeps’ 58.” The data is desktop only, and Ahrefs presents it as a correlation[23].
SparkToro analysed a Similarweb panel and found that 68.01% of US Google searches ended without a click in the first four months of 2026. The panel covers desktop and mobile web, not apps, and the author notes the data sources changed between years[24].
Google reads the picture differently. Its Head of Search wrote in August 2025 that “total organic click volume from Google Search to websites has been relatively stable year-over-year”, and called third-party reports of steep declines flawed[20]. Google published no figures that would let anyone check. Its documentation also says clicks from results pages with AI Overviews “are higher quality”, meaning people “are more likely to spend more time on the site”[6].
The zero-click search post covers what this means for your traffic. To find out whether your own queries show an AI Overview, and whether you are in it, see AI Overview tracking.
How Google builds your snippet
Your result is the one part of the page you can shape directly. Even so, you write the inputs, and Google writes the result.
The title link. Google’s system is automated. It looks at the <title> element, the main visual title, headings such as <h1>, the og:title tag, other large and prominent text, anchor text on the page, the text of links pointing to the page, and WebSite structured data[2]. Its advice: “Write descriptive and concise text for your <title> elements”, avoid keyword stuffing and boilerplate, and “make it clear which text is the main title for the page.” There is no length limit on a title element, but the title link “is truncated in Google Search results as needed, typically to fit the device width”[2]. Our title tags guide covers length and why Google rewrites titles.
The snippet. Google says “snippets are primarily created from the page content itself.” It “sometimes uses the meta description HTML element if it might give users a more accurate description of the page than content taken directly from the page.” And it “might show different snippets for different searches”[3]. So one page can have many snippets, one per kind of query. Google asks for a unique description on each page. There is no length limit on a meta description either: the snippet is cut to fit the screen[3].
The controls. nosnippet stops snippets, max-snippet caps their length, and data-nosnippet hides chosen text[3]. Use them with care. nosnippet also blocks featured snippets[4]. And a page must be “eligible to be shown in Google Search with a snippet” to be a supporting link in AI Overviews or AI Mode[6].
How to see your own result
Searching for yourself is the obvious check, and the least reliable one. Google says your position for a given search “might be different than the average because of many variables, such as your search history, location, and so on”[17]. A private window removes some history, not your location. Three better checks:
- Search Console’s Performance report. It shows clicks, impressions, click-through rate and average position, which is “the average position of the topmost result from your site”[18]. Two details matter. An AI Overview “occupies a single position in search results, and all links in the AI Overview are assigned that same position”[17]. And traffic from AI features is counted in the same report, under the Web search type[6].
- The Generative AI performance report. It shows impressions in AI Overviews and AI Mode, but no clicks. Google says it had rolled out to all websites as of 31 August 2026[19].
- A preview of your inputs. The SERP preview tool shows how your title and description lay out before you publish. It cannot predict a rewrite, so compare it with the live result once the page is indexed.
SERPs vs AI answer engines
ChatGPT and Perplexity do not have a SERP in the classic sense. There is no page of ranked links. There is one written answer, with sources cited inside it.
OpenAI’s help center says ChatGPT “can search the web to answer questions with current information and links to relevant sources”, and “may search the web automatically” when a question would benefit. Responses that use search “may include citations”, and a Sources button lists the cited pages and other links[26]. OpenAI launched it as a way to get “fast, timely answers with links to relevant web sources, which you would have previously needed to go to a search engine for”[27]. Perplexity describes the same shape: it searches the web in real time, writes a short answer, and adds numbered citations to the original sources[28].
That changes what “ranking” means. The answer is written fresh each time, and it moves. In a study by SparkToro and Gumshoe.ai, 600 volunteers ran 12 prompts 2,961 times. They found less than a 1 in 100 chance that ChatGPT or Google’s AI would give the same list of brands in any two responses. Rand Fishkin’s conclusion: “visibility % across dozens to hundreds of prompts run multiple times is a reasonable metric”, while tracking a “ranking position” in AI tools is foolhardy[25].
| What you get | How sources appear | Same answer every time? | |
|---|---|---|---|
| Google results page | A ranked page of results and features | Title links with snippets | No: varies with location, history and settings |
| Google AI Overview | A generated summary, usually at the top | Links to dig deeper | No: brand lists rarely repeated in the study |
| Google AI Mode | A conversational answer in its own tab | Links to the web, or a set of links when confidence is low | Not measured in the studies cited here |
| ChatGPT search | One answer, searching when useful | Citations in the answer and a Sources panel | No: brand lists rarely repeated in the study |
| Perplexity | One answer from a live web search | Numbered citations | Not measured in the studies cited here |
So the questions change. On a SERP you ask “what position are we in?” In an answer engine you ask “are we named, and how often?” The free AI visibility checker runs that second question for your category.
Tracking the answer, not only the rank
Search Console tells you where your links appear. It does not tell you whether an AI answer names your brand, or a competitor’s. CoreCited’s AI Visibility Tracking runs your buyers’ questions every week and records whether each answer names you. From the Starter plan, that covers Google’s AI Overviews and AI Mode as well as ChatGPT, Claude, Perplexity and Gemini. Every limit is on the pricing page.
Questions people ask
What does SERP stand for?
SERP stands for search engine results page. It is the page a search engine shows after you enter a query. On Google it holds ordinary results plus features such as ads, AI Overviews, featured snippets, People Also Ask, maps, products, videos and knowledge panels. Results differ from person to person, so there is no single SERP for a query.
What is the difference between SEO and a SERP?
SEO is the work. The SERP is where the work shows up. Search engine optimisation aims to earn a place on results pages, and the results page is where you see whether it did. Today one page has many places to appear: an organic result, a featured snippet, a People Also Ask answer, a link in an AI Overview, or a local listing.
What is a Google snippet?
The snippet is the description under the title link in a Google result. Google writes it automatically, mainly from the page's own content, and sometimes uses the meta description when that describes the page better. It can show different snippets for different searches. A featured snippet is a special version that reverses the usual layout and shows the text first, in a box.
What are SERP features?
Anything on the results page beyond a plain list of links: ads, AI Overviews, featured snippets, People Also Ask, the local map, knowledge panels, image and video results, product listings and sitelinks. A 2026 academic study of six search engines catalogued 143 distinct elements on results pages.
Do AI Overviews reduce clicks?
The independent and vendor studies say yes. Pew found people clicked a traditional result on 8% of visits with an AI summary and 15% without one. Ahrefs, a vendor, measured a 58% lower click-through rate for the top result when an AI Overview appeared. Google says total organic clicks have been relatively stable, without publishing figures.
Does ChatGPT have a SERP?
Not in the classic sense. ChatGPT search and Perplexity answer with one written response and cite sources inside it, instead of showing a ranked page of links. There is no position one to hold. What you can measure is whether you are named or cited, across many runs of the same question.
