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.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p>\n<\/div><\/div><\/div><div class=\"kc-elm kc-css-779683 kc_col-sm-5 kc_column kc_col-sm-5\"><div class=\"kc-col-container\"><div class=\"kc-elm kc-css-772699 kc_shortcode kc_single_image\">\n\n        <img decoding=\"async\" src=\"https:\/\/searchstudies.org\/wp-content\/uploads\/2024\/06\/Overlap.png\" class=\"\" alt=\"\" \/>    <\/div>\n<\/div><\/div><\/div><\/div><\/section><section class=\"kc-elm kc-css-63352 kc_row\"><div class=\"kc-row-container  kc-container\"><div class=\"kc-wrap-columns\"><div class=\"kc-elm kc-css-341375 kc_col-sm-12 kc_column kc_col-sm-12\"><div class=\"kc-col-container\"><div class=\"kc-elm kc-css-425852\" style=\"height: 20px; clear: both; width:100%;\"><\/div><\/div><\/div><\/div><\/div><\/section><section class=\"kc-elm kc-css-410465 kc_row\"><div class=\"kc-row-container  kc-container\"><div class=\"kc-wrap-columns\"><div class=\"kc-elm kc-css-840420 kc_col-sm-1 kc_column kc_col-sm-1\"><div class=\"kc-col-container\"><\/div><\/div><div class=\"kc-elm kc-css-797451 kc_col-sm-9 kc_column kc_col-sm-9\"><div class=\"kc-col-container\">\n<div class=\"kc-elm kc-css-590910 kc-title-wrap\">\n\n\t<h2 class=\"kc_title\">RAT functionality used<\/h2>\n<\/div>\n<div class=\"kc-elm kc-css-257207 kc_text_block\"><\/p>\n<p>\n<strong>Scrapers<\/strong>: Google (DE), Bing (DE), DuckDuckGo (DE), Metager (DE), Google (US), Bing (US), DuckDuckGo (US), Metager (US)<\/p>\n<p><strong>Data analysis<\/strong>: Overlap analysis<\/p>\n<p>\n<\/div><div class=\"kc-elm kc-css-88603\" style=\"height: 20px; clear: both; width:100%;\"><\/div><\/div><\/div><div class=\"kc-elm kc-css-851735 kc_col-sm-1 kc_column kc_col-sm-1\"><div class=\"kc-col-container\"><\/div><\/div><\/div><\/div><\/section><section class=\"kc-elm kc-css-473468 kc_row\"><div class=\"kc-row-container  kc-container\"><div class=\"kc-wrap-columns\"><div class=\"kc-elm kc-css-966299 kc_col-sm-12 kc_column kc_col-sm-12\"><div class=\"kc-col-container\"><div class=\"kc-elm kc-css-74053\" style=\"height: 20px; clear: both; width:100%;\"><\/div><\/div><\/div><\/div><\/div><\/section><section class=\"kc-elm kc-css-474397 kc_row\"><div class=\"kc-row-container  kc-container\"><div class=\"kc-wrap-columns\"><div class=\"kc-elm kc-css-684320 kc_col-sm-9 kc_column kc_col-sm-9\"><div class=\"kc-col-container\"><div class=\"kc-elm kc-css-765480\" style=\"height: 20px; clear: both; width:100%;\"><\/div>\n<div class=\"kc-elm kc-css-34849 kc-title-wrap\">\n\n\t<h2 class=\"kc_title\">Publications and presentations<\/h2>\n<\/div>\n<div class=\"kc-elm kc-css-87551 kc_text_block\"><\/p>\n<h4>Conference paper<\/h4>\n<p style=\"font-weight: 400;\">Yagci, N.; S\u00fcnkler, S.; H\u00e4u\u00dfler, H.; Lewandowski, D.
