  When it comes to search engines, users generally prefer Google. Our study
aims to find the differences between the results found in Google compared to
other search engines. We compared the top 10 results from Google, Bing,
DuckDuckGo, and Metager, using 3,537 queries generated from Google Trends from
Germany and the US. Google displays more unique domains in the top results than
its competitors. Wikipedia and news websites are the most popular sources
overall. With some top sources dominating search results, the distribution of
domains is also consistent across all search engines. The overlap between
Google and Bing is always under 32%, while Metager has a higher overlap with
Bing than DuckDuckGo, going up to 78%. This study shows that the use of another
search engine, especially in addition to Google, provides a wider variety in
sources and might lead the user to find new perspectives.
