Google Trendsis a public web facility ofGoogle Inc., based onGoogle Search, that shows how often a particular search-term is entered relative to the total search-volume across various regions of the world, and in various languages. The horizontal axis of the main graph represents time (starting from 2004), and the vertical is how often a term is searched for relative to the total number of searches, globally. Below the main graph, popularity is broken down by countries, regions, cities and language. Note that what Google calls language, however, does not display the relative results of searches in different languages for the same term(s). It only displays the relative combined search volumes from all countries that share a particular language (see flowers vs fleurs). It is possible to refine the main graph by region and time period. On August 5, 2008, Google launchedGoogle 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

Google Trends also allows the user to compare the relative search volume of searches between two or more terms.

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.2Google 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 Googles 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.3In 2012, the Insights for Search has been merged into Google Trends with a new interface.

In 2009,Yossi Matiaset al. published research on the predictability of search trends.4In a series of highly influential 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 Obamas vote share, he calculated that Obama lost about 4 percentage points due to racial animus in the 2008 presidential election.5He 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?6In 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?7He also examined cultural differences in attitudes around pregnancy.8

Evidence is provided byJeremy Ginsberget al. that Google Trends data can be used to track influenza-like illness in a population.9Because 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.10Inferences (influenza-like illness rates) from this model for England are presented on theFlu Detectorwebsite.

Furthermore, it was shown byTobias Preiset 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.1112

In April 2012,Tobias PreisHelen Susannah MoatH. Eugene StanleyandSteven R. Bishopused 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 journalScientific Reports, suggest there may be a link between online behaviour and real-world economic indicators.131415The authors of the study examined Google search queries made by Internet 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), 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 Preisand his colleaguesHelen Susannah MoatandH. Eugene Stanleyintroduced a method to identify online precursors for stock market moves, using trading strategies based on search volume data provided by Google Trends.16Their analysis ofGooglesearch volume for 98 terms of varying financial relevance, published inScientific Reports,17suggests that increases in search volume for financially relevant search terms tend to precede large losses in financial markets.1819202122232425

The analysis of Tobias Preis was later found to be misleading and the results are most likely to be overfitted.26The 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.17

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 really quickly if you are not logged in into your Google account before trying to access the trends service27

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.28For 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 aniGoogleGadget. Hot Trends is also available as an hourly.

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 byAlexa Internet. The Google Trends for Websites became unavailable after the September 27th, 2012 release of the new google trends product.29

An API to accompany the Google Trends service was announced byMarissa Mayer, then vice president of search-products and user experience at Google. This was announced in 2007, and so far has not been released.30

A few unofficial Google Trends API tools have been released, along with a wiki detailing them and simple access to Google Trends data. In addition, in May 2018, software developer Martin Spano released an extension of Google Trends calledKeywordsApp, which is online database of over 300 million top Google keywords.31

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. Congressional 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.32Another 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.33
