Safari browser comes with Google search as its default search engine. If you’re annoyed by the increasing spam-filled search results using Google, you might want to consider alternative such as Bing.
On the Mac, it is easy to change the default search engine for Safari. Simply click the search icon beside the search area on the right end of the toolbar. A drop-down menu will appear for you to select the default search engine.
On iOS for iPhone, iPad and iPod touch, the default search engine is set using the Settings app.
From the Settings app, tap on the Safari icon. Tap the “Search Engine” option to select the new default search engine.
