Google Trends is a website by Google that analyzes the popularity of top search queries in Google Search across various regions and languages. The website uses graphs to compare the search volume of different queries over a certain period of time.
On August 5, 2008, Google launched Google Insights for Search, a more sophisticated and advanced service displaying search trends data. On September 27, 2012, Google merged Google Insights for Search into Google Trends. [1]
Originally, Google neglected updating Google Trends on a regular basis. In March 2007, internet bloggers noticed that Google had not added new data since November 2006, and Trends was updated within a week. Google did not update Trends from March until July 30, and only after it was blogged about, again. [2] Google now claims to be "updating the information provided by Google Trends daily; Hot Trends is updated hourly."
On August 6, 2008, Google launched a free service called Insights for Search. Insights for Search is an extension of Google Trends and although the tool is meant for marketers, it can be utilized by any user. The tool allows for the tracking of various words and phrases that are typed into Google's search-box. The tracking device provided a more-indepth analysis of results. It also has the ability to categorize and organize the data, with special attention given to the breakdown of information by geographical areas. [3] In 2012, Google Insights for Search was merged into Google Trends with a new interface. [1]
Google Trends does not provide absolute values for the number of search queries, but relative search volumes (RSV). The relative search volumes are normalised to the highest value, which is set to 100. [4] The popularity of up to 5 search terms or search topics can be compared directly. Additional comparisons require a comparison term or topic. [5] In contrast to search terms, search topics are "a group of terms that have the same concept in any language". [6]
In 2009, Yossi Matias et al. published research on the predictability of search trends. [7] In a series of articles in The New York Times , Seth Stephens-Davidowitz used Google Trends to measure a variety of behaviors. For example, in June 2012, he argued that search volume for the word "nigger(s)" could be used to measure racism in different parts of the United States. Correlating this measure with Obama's vote share, he calculated that Obama lost about 4 percentage points due to racial animus in the 2008 presidential election. [8] He also used Google data, along with other sources, to estimate the size of the gay population. This article noted that the most popular search beginning "is my husband" is "is my husband gay?" [9] In addition, he found that American parents were more likely to search "is my son gifted?" than "is my daughter gifted?" But they were more likely to search "is my daughter overweight?" than "is my son overweight?" [10] He also examined cultural differences in attitudes around pregnancy. [11]
Google Trends has also been used to forecast economic indicators, [12] [13] [14] and financial markets, [15] and analysis of Google Trends data has detected regional flu outbreaks before conventional monitoring systems. [16] Google Trends is increasingly used in ecological and conservation studies, with the number of research articles growing over 50% per year. [17] Google Trends data has been used to examine trends in public interest and awareness on biodiversity and conservation issues, [18] [19] [20] [21] [22] species bias in conservation project, [23] and identify cultural aspects of environmental issues. [24] The data obtained from Google Trends has also been used to track changes in the timing biological processes as well as the geographic patterns of biological invasion. [25]
A 2011 study found that an indicator for private consumption based on search query time series provided by Google Trends found that in almost all conducted forecasting experiments, the Google indicator outperformed survey-based indicators. [26]
Evidence is provided by Jeremy Ginsberg et al. that Google Trends data can be used to track influenza-like illness in a population. [27] Because the relative frequency of certain queries is highly correlated with the percentage of physician visits in which a patient presents with influenza-like symptoms, an estimate of weekly influenza activity can be reported. A more sophisticated model for inferring influenza rates from Google Trends, capable of overcoming the mistakes of its predecessors has been proposed by Lampos et al. [28]
The use of Google Trends to study a wide range of medical topics is becoming more widespread. Studies have been performed examining such diverse topics as use of tobacco substitutes, [29] suicide occurrence, [30] asthma, [31] and parasitic diseases. [32] In an analogous concept of using health queries to predict the flu, Google Flu Trends was created. [27] [33] Further research should extend the utility of Google Trends in healthcare.
Furthermore, it was shown by Tobias Preis et al. that there is a correlation between Google Trends data of company names and transaction volumes of the corresponding stocks on a weekly time scale. [36] [37]
In April 2012, Tobias Preis, Helen Susannah Moat, H. Eugene Stanley and Steven R. Bishop used Google Trends data to demonstrate that Internet users from countries with a higher per capita gross domestic product (GDP) are more likely to search for information about the future than information about the past. The findings, published in the journal Scientific Reports, suggest there may be a link between online behaviour and real-world economic indicators. [38] [39] [40] The authors of the study examined Google search queries made by Internet users in 45 countries in 2010 and calculated the ratio of the volume of searches for the coming year (‘2011’) to the volume of searches for the previous year (‘2009’), which they call the ‘future orientation index’. They compared the future orientation index to the per capita GDP of each country and found a strong tendency for countries in which Google users enquire more about the future to exhibit a higher GDP. The results hint that there may potentially be a relationship between the economic success of a country and the information-seeking behaviour of its citizens online.
In April 2013, Tobias Preis and his colleagues Helen Susannah Moat and H. Eugene Stanley introduced a method to identify online precursors for stock market moves, using trading strategies based on search volume data provided by Google Trends. [41] Their analysis of Google search volume for 98 terms of varying financial relevance, published in Scientific Reports , [42] suggests that increases in search volume for financially relevant search terms tend to precede large losses in financial markets. [43] [44] [45] [46] [47] [48] [49] [50]
The analysis of Tobias Preis was later found to be misleading and the results are most likely to be overfitted. [51] The group of Damien Challet tested the same methodology with unrelated to financial markets search words, such as terms for diseases, car brands or computer games. They have found that all these classes provide equally good "predictability" of the financial markets as the original set. For example, the search terms like "bone cancer", "Shelby GT 500" (car brand), "Moon Patrol" (computer game) provide even better performance as those selected in original work. [42]
In 2019, Tom Cochran, from public relations firm 720 Strategies, conducted a study comparing Google Trends to political polling. [52] The study was in response to Pete Buttigieg's surge in a poll of Iowa's likely Democratic caucusgoers conducted between November 8 to 13 by the Des Moines Register. Using Google Trends, he looked into the relationship between polling numbers and Google searches. His findings concluded that, while polling consists of far smaller sample sizes, the primary difference with Google Trends is that it only demonstrates intent to seek information. Google search volume was higher for candidates having higher polling numbers, but the correlation did not mean increased candidate favorability. [53]
Research also shows that Google Trends can be used to forecast stock returns and volatility over a short horizon. [54] Other research has shown that Google Trends has strong predictive power for macroeconomic series. For example, a paper published in 2020 shows that a large panel of Google Trends predictors can forecast employment growth in the United States at both the national and state level with a relatively high degree of accuracy even a year in advance. [55]
Google Trends uses representative sub-samples for analysis, which means that the data can vary depending on the time of the survey and is associated with background noise. [56] Therefore, repeating analyses at different points in time can increase the reliability of the analysis. [56] [57] It was shown that Google Trends data can exhibit a high variability when queried at different points in time, indicating that it may not be reliable except for very frequent search terms due to sampling, [58] and relying on this data for prediction is risky. In 2020, this research made it to major headlines in Germany. [59]
Google has incorporated quota limits for Trends searches. This limits the number of search attempts available per user/IP/device. Details of quota limits have not yet been provided, but it may depend on geographical location or browser privacy settings. It has been reported in some cases that this quota is reached very quickly if one is not logged into a Google account before trying to access the Trends service. [60]
Google Hot Trends is an addition to Google Trends which displays the top 20 hot, i.e., fastest rising, searches (search-terms) of the past hour in various countries. This is for searches that have recently experienced a sudden surge in popularity. [61] For each of the search-terms, it provides a 24-hour search-volume graph as well as blog, news and web search results. Hot Trends has a history feature for those wishing to browse past hot searches. Hot Trends can be installed as an iGoogle Gadget. Hot Trends is also available as an hourly Atom web feed.
Since 2008, there has been a sub-section of Google Trends which analyses traffic for websites, rather than traffic for search terms. This is a similar service to that provided by Alexa Internet. The Google Trends for Websites became unavailable after the September 27, 2012, release of the new Google Trends product. [62]
An API to accompany the Google Trends service was announced by Marissa Mayer, then vice president of search-products and user experience at Google. This was announced in 2007, and so far has not been released. [63]
A group of researchers at Wellesley College examined data from Google Trends and analyzed how effective a tool it could be in predicting U.S. Congress elections in 2008 and 2010. In highly contested races where data for both candidates were available, the data successfully predicted the outcome in 33.3% of cases in 2008 and 39% in 2010. The authors conclude that, compared to the traditional methods of election forecasting, incumbency and New York Times polls, and even in comparison with random chance, Google Trends did not prove to be a good predictor of either the 2008 or 2010 elections. [64] Another group has also explored possible implications for financial markets and suggested possible ways to combine insights from Google Trends with other concepts in technical analysis. [65]

: CS1 maint: multiple names: authors list (link)Prediction markets, also known as betting markets, information markets, decision markets, idea futures or event derivatives, are open markets that enable the prediction of specific outcomes using financial incentives. They are exchange-traded markets established for trading bets in the outcome of various events. The market prices can indicate what the crowd thinks the probability of the event is. A typical prediction market contract is set up to trade between 0 and 100%. The most common form of a prediction market is a binary option market, which will expire at the price of 0 or 100%. Prediction markets can be thought of as belonging to the more general concept of crowdsourcing which is specially designed to aggregate information on particular topics of interest. The main purposes of prediction markets are eliciting aggregating beliefs over an unknown future outcome. Traders with different beliefs trade on contracts whose payoffs are related to the unknown future outcome and the market prices of the contracts are considered as the aggregated belief.
Text mining, text data mining (TDM) or text analytics is the process of deriving high-quality information from text. It involves "the discovery by computer of new, previously unknown information, by automatically extracting information from different written resources." Written resources may include websites, books, emails, reviews, and articles. High-quality information is typically obtained by devising patterns and trends by means such as statistical pattern learning. According to Hotho et al. (2005), there are three perspectives of text mining: information extraction, data mining, and knowledge discovery in databases (KDD). Text mining usually involves the process of structuring the input text, deriving patterns within the structured data, and finally evaluation and interpretation of the output. 'High quality' in text mining usually refers to some combination of relevance, novelty, and interest. Typical text mining tasks include text categorization, text clustering, concept/entity extraction, production of granular taxonomies, sentiment analysis, document summarization, and entity relation modeling.
Analytics is the systematic computational analysis of data or statistics. It is used for the discovery, interpretation, and communication of meaningful patterns in data, which also falls under and directly relates to the umbrella term, data science. Analytics also entails applying data patterns toward effective decision-making. It can be valuable in areas rich with recorded information; analytics relies on the simultaneous application of statistics, computer programming, and operations research to quantify performance.
Econophysics is a non-orthodox interdisciplinary research field, applying theories and methods originally developed by physicists in order to solve problems in economics, usually those including uncertainty or stochastic processes and nonlinear dynamics. Some of its application to the study of financial markets has also been termed statistical finance referring to its roots in statistical physics. Econophysics is closely related to social physics.
In web analytics and website management, a pageview or page view, abbreviated in business to PV and occasionally called page impression, is a request to load a single HTML file of an Internet site. On the World Wide Web, a page request would result from a web surfer clicking on a link on another page pointing to the page in question.
Public health surveillance is, according to the World Health Organization (WHO), "the continuous, systematic collection, analysis and interpretation of health-related data needed for the planning, implementation, and evaluation of public health practice." Public health surveillance may be used to track emerging health-related issues at an early stage and find active solutions in a timely manner. Surveillance systems are generally called upon to provide information regarding when and where health problems are occurring and who is affected.
Market sentiment, also known as investor attention, is the general prevailing attitude of investors as to anticipated price development in a market. This attitude is the accumulation of a variety of fundamental and technical factors, including price history, economic reports, seasonal factors, and national and world events. If investors expect upward price movement in the stock market, the sentiment is said to be bullish. On the contrary, if the market sentiment is bearish, most investors expect downward price movement. Market participants who maintain a static sentiment, regardless of market conditions, are described as permabulls and permabears respectively. Market sentiment is usually considered as a contrarian indicator: what most people expect is a good thing to bet against. Market sentiment is used because it is believed to be a good predictor of market moves, especially when it is more extreme. Very bearish sentiment is usually followed by the market going up more than normal, and vice versa. A bull market refers to a sustained period of either realized or expected price rises, whereas a bear market is used to describe when an index or stock has fallen 20% or more from a recent high for a sustained length of time.
Technology forecasting attempts to predict the future characteristics of useful technological machines, procedures or techniques. Researchers create technology forecasts based on past experience and current technological developments. Like other forecasts, technology forecasting can be helpful for both public and private organizations to make smart decisions. By analyzing future opportunities and threats, the forecaster can improve decisions in order to achieve maximum benefits. Today, most countries are experiencing huge social and economic changes, which heavily rely on technology development. By analyzing these changes, government and economic institutions could make plans for future developments. However, not all of historical data can be used for technology forecasting, forecasters also need to adopt advanced technology and quantitative modeling from experts’ researches and conclusions.
Gunther Eysenbach is a German-Canadian researcher on healthcare, especially health policy, eHealth, and consumer health informatics.
Stock market prediction is the act of trying to determine the future value of a company stock or other financial instrument traded on an exchange. The successful prediction of a stock's future price could yield significant profit. The efficient market hypothesis suggests that stock prices reflect all currently available information and any price changes that are not based on newly revealed information thus are inherently unpredictable. Others disagree and those with this viewpoint possess myriad methods and technologies which purportedly allow them to gain future price information.
Big data primarily refers to data sets that are too large or complex to be dealt with by traditional data-processing software. Data with many entries (rows) offer greater statistical power, while data with higher complexity may lead to a higher false discovery rate.

He was awarded a PhD in physics from the Johannes Gutenberg University of Mainz in Germany.
Culturomics is a form of computational lexicology that studies human behavior and cultural trends through the quantitative analysis of digitized texts. Researchers data mine large digital archives to investigate cultural phenomena reflected in language and word usage. The term is an American neologism first described in a 2010 Science article called Quantitative Analysis of Culture Using Millions of Digitized Books, co-authored by Harvard researchers Jean-Baptiste Michel and Erez Lieberman Aiden.
Infoveillance is a type of syndromic surveillance that specifically utilizes information found online. The term, along with the term infodemiology, was coined by Gunther Eysenbach to describe research that uses online information to gather information about human behavior.
The Google Books Ngram Viewer is an online search engine that charts the frequencies of any set of search strings using a yearly count of n-grams found in printed sources published between 1500 and 2022 in Google's text corpora in English, Chinese (simplified), French, German, Hebrew, Italian, Russian, or Spanish. There are also some specialized English corpora, such as American English, British English, and English Fiction.
Google Flu Trends (GFT) was a web service operated by Google. It provided estimates of influenza activity for more than 25 countries. By aggregating Google Search queries, it attempted to make accurate predictions about flu activity. This project was first launched in 2008 by Google.org to help predict outbreaks of flu.
The Future Orientation Index was introduced by Tobias Preis, Helen Susannah Moat, H. Eugene Stanley and Steven Bishop using Google Trends to demonstrate that Google users from countries with a higher per capita GDP are more likely to search for information about the future than information about the past. The findings suggest there may be a link between online behaviour and real-world economic indicators. The authors of the study examined Google query logs made by Google users in 45 different countries in 2010 and calculated the ratio of the volume of searches for the coming year (‘2011’) to the volume of searches for the previous year (‘2009’).
Infodemiology was defined by Gunther Eysenbach in the early 2000s as information epidemiology. It is an area of science research focused on scanning the internet for user-contributed health-related content, with the ultimate goal of improving public health. Later, it is also defined as the science of mitigating public health problems resulting from an infodemic.
Data philanthropy refers to private sector companies sharing data they collected for the public good, often to help address social or environmental challenges for public benefit. The concept was popularized through its introduction by the United Nations Global Pulse initiative in 2011 to leverage corporate data assets for humanitarian, academic, and societal causes. For instance, anonymized mobile data has been used to track disease outbreaks. In contrast, corporate data on consumer behavior may be shared with researchers to study public health and economic trends.
Seth Isaac Stephens-Davidowitz is an American data scientist, economist, and author. He has worked as a New York Times op-ed contributor, a data scientist at Google, as well as a visiting lecturer at the Wharton School of the University of Pennsylvania. He has published research using Google Trends search data, as well as data from Wikipedia and Facebook, to gain real-time insights into people's thoughts and beliefs that they may be unwilling to admit publicly.
