Stop pop-up ads and adware in Safari
If the advertisements are annoying, know that you can block ads on safari for iphone and ipad. Here are Apple’s recommendations on how to control pop-up ads and ad-injection software (adware):
Stopping pop-up ads
To control pop-ups, update your software and adjust Safari settings. In some cases, you might need to remove adware. Like phishing email, some pop-ups pretend to be from Apple or another trusted company to trick you into giving personal information. If you’re concerned about a pop-up, follow the steps below or contact Apple.
Start by closing any pop-ups that are open. If you see a Block Alerts button after dismissing a pop-up on your iPhone, iPad, or iPod touch, tap the button to stop showing alerts from that webpage.
If a pop-up won’t close, on your iPhone, iPad, or iPod touch, force Safari to close. To prevent Safari from automatically reopening any windows, go to Settings > Safari, then tap Clear History and Website Data. This also removes your browser history and cookies.
Update your software
Keep your iOS software up to date. Some software updates, such as OS X Yosemite v10.10.4, include improvements that help control pop-ups.
Check Safari settings and extensions
Go to settings. Select Safari. Under General, toggle on “Block Pop-ups”.
Stop ads and view ad-free content in Safari
On iOS9, you can block ads on safari for iphone and ipad that display on sites using a third-party extension.
Simply install an Ad-blocker application (here is a list of ad-block apps for iOS9). Go to Settings > Safari and scroll down to Content Blockers. Flip the switch to enable/disable your content blocker(s) of choice.
