14 DAY TRIAL // As of today, Apple chooses to use Google instead of Microsoft's Bing for web search results on Siri for iOS and macOS, as well as on the Spotlight feature of macOS Sierra or High Sierra and iOS' built-in search functionality.
In a statement given to TechCrunch this morning, Apple confirms the switch from Bing to Google for web search results provided by either Siri or Spotlight on both iOS and macOS operating systems, claiming that the drastic change has to do with consistency across all of its supported Mac and iOS devices, but we know that Google paid Apple $3 billion to remain default search engine on iOS and macOS.
"Switching to Google as the web search provider for Siri, Search within iOS and Spotlight on Mac will allow these services to have a consistent web search experience with the default in Safari," said Apple in a statement for TechCrunch. "We have strong relationships with Google and Microsoft and remain committed to delivering the best user experience possible."
Users can still use Bing as default search engine for Safari
If for some reason you don't want your web searches to be processed by Google, you are free to re-enable Microsoft's Bing on your iPhone, iPad, iPod touch or Mac, but only for the Safari web browser. Yahoo and DuckDuckGo are also available as possible search engines on the latest iOS 11 and macOS High Sierra 10.13 operating systems.
Unfortunately, there's no way to re-enable Bing for Siri or Spotlight web search results, though not all users will see the switch at the same time. Apple began the swap at 9:00 a.m. PT (4:00 p.m. GMT), and, according to TechCrunch, it would appear that while web links results are from Google Search, video results are from YouTube, and image results are still provided by Bing at the time of writing.
