26-510: The results are of two general types: The results are normally ranked by relevance to the query. Each result displayed on the SERP normally includes a title, a link that points to the actual page on the Web , and a short description , known as a snippet, showing where the keywords have matched content within the page for organic results. For sponsored results, the advertiser chooses what to display. With

52-437: A relevance level to each retrieved result, a process known as relevance assessment . Relevance levels can be binary (indicating a result is relevant or that it is not relevant), or graded (indicating results have a varying degree of match between the topic of the result and the information need). Once relevance levels have been assigned to the retrieved results, information retrieval performance measures can be used to assess

78-434: A search query matches it will display an additional sub-window on right-hand side with information from its sources. Such panels may offer the user a zero-click result to their query. Google Discover formerly known as Google Feed is a way of getting topics and news information to users on the homepage below the search box. Major search engines like Google , Yahoo! , Bing , Sogou primarily use content contained within

104-431: A high likelihood of being relevant to the same information need. With respect to the embedding similarity space, the cluster hypothesis can be interpreted globally or locally. The global interpretation assumes that there exist some fixed set of underlying topics derived from inter-document similarity. These global clusters or their representatives can then be used to relate relevance of two documents (e.g. two documents in

130-461: A personal capacity alone, rather than in a Google-endorsed formal capacity. Relevance (information retrieval) In information science and information retrieval , relevance denotes how well a retrieved document or set of documents meets the information need of the user. Relevance may include concerns such as timeliness, authority or novelty of the result. The concern with the problem of finding relevant information dates back at least to

156-433: A private individual in the same way as they do to one of Google's Ad Partners. Further, crawling itself remains one of the core elements of Google's search functionality and tools; purported 'warnings' against scraping previously attributed to Google, were in reality posts on third-party platforms such as Twitter that were manifestly by individuals not necessarily associated with or employed by Google, and in any event made in

182-471: A query may have an ambiguous interpretation, or a variety of potential responses. Providing a diversity of results can be a consideration when evaluating the utility of a result set. Google Algorithm updates in 2017 Google Search , offered by Google , is the most widely used search engine on the World Wide Web as of 2023, with over eight billion searches a day. This page covers key events in

208-470: Is complicated by the dynamics of consumer expectations and intent— unlike static print media where the content and the advertising on every page are the same all of the time for all viewers, despite such hard copy being localized to some degree, usually geographic, like state, metro-area, city, or neighbourhood , search engine results can vary based on individual factors such as browsing habits. The organic search results, queries, and advertisements are

234-475: Is presented as a visual element composed of attribution, a title link, and a snippet of the matching webpage showing how the query matched on the page. Search results pages typically contain numerous organic results, and users tend to view only the first results on the first page. According to a 2019 study, the click-through rates ( CTRs ) drop significantly after the first few results. Several major search engines offer "sponsored results" to companies, who may pay

260-411: The evolution of SERPs interfaces from 2000 to 2020 shows that SERP are becoming more diverse in terms of elements, aggregating content from different verticals and including more features that provide direct answers. The major search engines visually differentiate specific content types such as images , news , and blogs . Many content types have specialized SERP templates and visual enhancements on

286-407: The first page of search results. For example, two duplicate documents might be individually considered quite relevant, but it is only useful to display one of them. A measure called "maximal marginal relevance" (MMR) has been proposed to manage this shortcoming. It considers the relevance of each document only in terms of how much new information it brings given the previous results. In some cases,

312-409: The first publication of scientific journals in the 17th century. The formal study of relevance began in the 20th century with the study of what would later be called bibliometrics . In the 1930s and 1940s, S. C. Bradford used the term "relevant" to characterize articles relevant to a subject (cf., Bradford's law ). In the 1950s, the first information retrieval systems emerged, and researchers noted

338-405: The first search results page. Also known as 'user search string', this is the word or set of words that are typed by the user in the search bar of the search engine. The search box is located on all major search engines like Google , Yahoo , Bing , and Sogou . Users indicate the topic desired based on the keywords they enter into the search box in the search engine. Organic SERP listings are

364-402: The natural listings generated by search engines , they list webpages matching the query. The pages are sorted on a relevance score based on a series of metrics generally based upon factors such as quality and relevance of the content, expertise, authoritativeness, trustworthiness of the website and author on a given topic, good user experience , and backlinks . Each of the matching web pages

390-506: The page and fallback to metadata tags of a web page to generate the content that makes up a search snippet . Generally, the HTML title tag will be used as the title of the snippet while the most relevant or useful contents of the web page ( description tag or page copy) will be used for the description. Search engine result pages are protected from automated access by a range of defensive mechanisms and terms of service. These result pages are

416-496: The position of websites and show the effectiveness of SEO as well as keywords that may need more SEO investment to rank higher. There is no evidence of Google making any public announcement as to the practice of scraping being in breach of its terms of service, as previously documented in this section, as any such 'warnings' could not, by their nature, apply universally to its users as well as, say, users in countries where Google does not operate, nor would they be capable of applying to

442-454: The primary data source for Search engine optimization , the website placement for competitive keywords that has become an important field of business and interest. The process of harvesting search engine result pages data is usually called " search engine scraping " or in a general form " web crawling " and generates the data SEO-related companies need to evaluate website competitive organic and sponsored rankings. This data can be used to track

468-448: The quality of a retrieval system's output. In contrast to this focus solely on topical relevance, the information science community has emphasized user studies that consider user relevance. These studies often focus on aspects of human-computer interaction (see also human-computer information retrieval ). The cluster hypothesis , proposed by C. J. van Rijsbergen in 1979, asserts that two documents that are similar to each other have

494-539: The retrieval of irrelevant articles as a significant concern. In 1958, B. C. Vickery made the concept of relevance explicit in an address at the International Conference on Scientific Information. Since 1958, information scientists have explored and debated definitions of relevance. A particular focus of the debate was the distinction between "relevance to a subject" or "topical relevance" and "user relevance". The information retrieval community has emphasized

520-576: The same cluster should both be relevant to the same request). Methods in this spirit include: A second interpretation, most notably advanced by Ellen Voorhees , focuses on the local relationships between documents. The local interpretation avoids having to model the number or size of clusters in the collection and allow relevance at multiple scales. Methods in this spirit include: Local methods require an accurate and appropriate document similarity measure . The documents which are most relevant are not necessarily those which are most useful to display in

546-517: The search engine to have their products or services appear above other search hits. This is often done in the form of bidding between companies, where the highest bidder gets the top result. A 2018 report from the European Commission showed that consumers generally avoid these top results, as there is an expectation that the topmost results on a search engine page will be sponsored, and thus less relevant. Rich snippets are displayed by Google in

572-450: The search results pages when a website contains content in structured data markup. Structured data markup helps the Google algorithm to index and understand the content better. Google supports rich snippets for various data types, including products, recipes, reviews, events, news articles, and job postings. A featured snippet is a summary of an answer to a user's query. This snippet appears at

598-470: The three main components of the SERP , However, the SERP of major search engines, like Google , Yahoo! , Bing , and Sogou may include many different types of enhanced results ( organic search , and sponsored) such as rich snippets, images, maps, definitions, answer boxes, videos or suggested search refinements. A study revealed that 97% of queries in Google returned at least one rich feature. Another study on

624-536: The top of the list of search hits. Google supports the following types of featured snippets: Paragraph Featured Snippet, Numbered List Featured Snippet, Bulleted List Featured Snippet, Table Featured Snippet, YouTube Featured Snippet, Carousel Snippet, Double Featured Snippet, and Two-for-One Featured Snippet. Search engines like Google , Bing, Sogou have started to expand their data into Encyclopedia and other rich sources of information. Google for example calls this sort of information " Google Knowledge Graph ", if

650-612: The use of test collections and benchmark tasks to measure topical relevance, starting with the Cranfield Experiments of the early 1960s and culminating in the TREC evaluations that continue to this day as the main evaluation framework for information retrieval research. In order to evaluate how well an information retrieval system retrieved topically relevant results, the relevance of retrieved results must be quantified. In Cranfield -style evaluations, this typically involves assigning

676-482: The vast amount of content available online, it's no surprise that a single search query can yield countless pages of results. However, in order to avoid overwhelming users, search engines and personal preferences often limit the number of results displayed per page. As a result, subsequent pages may not be as relevant or ranked as highly as the first. Just like the world of traditional print media and its advertising , this enables competitive pricing for page real estate but
