For my unit 4 assignment, the three search engines I chose to use were Google, Bing, and Yandex to research my football concussions topic. There were multiple similarities and differences between the three I used. Similarities that stood out were they all have a search box, they all are simple to use to search information, they all have ads that pop up while searching, they all have their own images, maps, and email. Differences that stood out were Bing gives out the best autocomplete suggestions versus the other two, Google looks the simplest/easiest to search on, Bing looks the most aesthetic, and Yandex looks complex. Lastly, Yandex did not have a search with a microphone button, but Google and Bing did.
