Google offers public access to global search volumes through its
search engine through the Google Trends portal. The
globaltrends package downloads search volumes provided by
Google Trends and uses them to measure and analyze the
distribution of search trends across countries or within
countries. globaltrends allows researchers and
analysts to investigate patterns within these trends, such as
degree of internationalization of firms and
organizations or dissemination of political, social, or technological
trends across the globe or within single countries.
To measure degree of internationalization, globaltrends
offers a wide array of empirical possibilities. It allows researchers to
compare degree of internationalization for various organizations
on a unified scale. In addition, the time-series nature of
Google Trends allows for historical analysis of
internationalization patterns and speed within
organizations.
The enormous detail of the data opens additional applications in
research that are impossible with traditional measures of
internationalization. For instance, using globaltrends on a
subnational level allows researchers to study proliferation
within a country and, for example, to trace a particular market
entry. In addition, globaltrends offers applications beyond
corporate internationalization, such as data on global interest
in products, persons, events, fads or scandals, even academic authors
and papers.
globaltrends provides user-friendly access to Google
Trends. The package
vignette offers additional technical details and a basic tutorial.
