Where to find the search engine setting on your iPhone
Your iPhone's default search engine is set in the Safari browser settings, not in a general system menu. Open the Settings app, scroll down and tap Safari, then look for the option labeled Search Engine. The current engine appears next to it — usually Google, but it could be Bing, Yahoo, or DuckDuckGo depending on what was set before.
Tap the Search Engine row to see all available options. Apple offers four built-in choices: Google, Bing, Yahoo, and DuckDuckGo. Select whichever one you want, and the change takes effect when ready. Any new searches you perform in Safari's address bar will use your newly selected engine.
Key Takeaways
- Search engine settings live in Settings > Safari > Search Engine, not in a system-wide preferences menu.
- Apple offers four search engines: Google, Bing, Yahoo, and DuckDuckGo — you cannot add a custom engine through the standard settings.
- The change applies only to Safari searches; other browsers like Chrome or Firefox have their own separate search engine settings.
- Changing the search engine does not affect Siri voice searches, which continue to use Apple's own search results.
What happens when you change the search engine
Once you select a new search engine, Safari uses it whenever you type a search term into the address bar. If you type "weather forecast" in the address bar, Safari sends that query to your chosen engine instead of the previous one. Bookmarks, history, and saved passwords are not affected by the change.
If you change your mind later, you can switch back to any of the four options at any time using the same Settings path. There is no limit to how often you can change it, and no confirmation dialog appears — the new engine becomes active as soon as you tap it.
Using a different search engine in Chrome or Firefox
If you use Chrome, Firefox, or another third-party browser on your iPhone, that browser has its own search engine setting separate from Safari. Open the browser's settings (usually found by tapping the menu icon or your profile picture), look for a Search Engine or Search option, and choose from that app's available engines.
Chrome on iPhone, for example, lets you pick from Google, Bing, Yahoo, and DuckDuckGo — the same four options as Safari. Firefox offers similar choices. Changing the search engine in one browser does not change it in another, so you may need to adjust settings in multiple apps if you use more than one.
Why Siri searches do not change with your Safari setting
Siri voice searches use Apple's own search results and do not respect your Safari search engine choice. If you ask Siri "What is the capital of France?" or use Siri to search the web, the results come from Apple's search index, not from Google, Bing, or whichever engine you selected for Safari.
This is by design — Apple does not offer a way to change Siri's search engine. If you want to search using your preferred engine, you will need to open Safari (or another browser) and type your query into the address bar instead of using Siri.
Adding a custom search engine is not possible on iPhone
Unlike some desktop browsers, Safari on iPhone does not let you add a custom search engine or use a search engine that is not in Apple's built-in list. You are limited to Google, Bing, Yahoo, and DuckDuckGo. If you need a search engine not on that list — such as Ecosia, Startpage, or a company-specific search tool — you would need to visit that engine's website directly each time you want to search.
Some third-party browsers on the App Store may offer more search engine options, but they are not integrated into Safari itself. If a particular search engine is important to your workflow, checking that browser's settings before downloading can help you decide whether it meets your needs.
Troubleshooting a search engine that will not change
If you tap a search engine in Settings but Safari continues to use the old one, try closing Safari completely and reopening it. Swipe up from the bottom of the screen (or swipe down from the top-right corner on newer iPhones) to access the app switcher, find Safari, and swipe it away to close it fully. Then reopen Safari and test a search.
If the problem persists, restart your iPhone. Press and hold the power button and volume down button together until the power-off slider appears, then slide to power off. Wait a few seconds, then press the power button again to turn it back on. After restart, check Settings > Safari > Search Engine again to confirm your choice is still selected, then test a search in Safari.
Frequently Asked Questions
Does changing my search engine in Safari affect Google searches on other apps?
No. Your Safari search engine setting only affects searches you perform in Safari's address bar. Google Maps, Gmail, Google Drive, and other Google apps continue to work normally and are not affected by your Safari setting.
Can I set a different search engine for private browsing?
No. Safari uses the same search engine for both regular and private browsing tabs. The setting in Settings > Safari > Search Engine applies to all Safari searches, regardless of which mode you are using.
What is the difference between these four search engines?
Google is the largest and returns the most results. Bing is Microsoft's engine and integrates with Windows devices. Yahoo uses Bing's results but adds its own interface. DuckDuckGo emphasizes privacy and does not track your searches. All four are free to use.
If I change my search engine, will my old search history disappear?
No. Your search history in Safari remains unchanged when you switch search engines. The history shows what you searched for, not which engine you used. You can still view and clear your history through Settings > Safari > Clear History and Website Data.
Why does my iPhone keep switching back to Google?
This usually happens if you have not fully closed Safari after changing the setting, or if your iPhone restarted before the change was saved. Make sure you tap your chosen engine in Settings, then close and reopen Safari to confirm the change took effect.
