A new study found that the top 10 search results from Google and Bing can differ up to 75% for the same query. Researchers at HAW Hamburg compared the results of four major search engines (Google, Bing, DuckDuckGo and Metager) and found significant variations. They tested over 3500 popular queries and discovered that Google and Bing had the most diverse results. This means that users may need to check multiple search engines to get a comprehensive answer to their search queries.
