Prioritising search with the right result almost always on the first page. Stripped back interface. Back in the day search engines could be and often were a crapshoot, then along comes Google and surfaces what you are after first time the vast majority of times you used it. Plus the Google search page was a logo a text box and 2 buttons, you had to go looking for a weather report, a stock ticker, a news feed, an entertainment feed, etcetera etcetera. It was the disruptive tech upstart, now it’s the incumbent, basically all the evangelist algorithm nerds took their stock options and bailed. Now we have advertising obsessed business majors and cryptobros piloting the zombie husk of Google around.
