When you’re wandering around the web, sometimes it’s a good idea to check where a link goes before simply tapping on it. To do this on an iPhone, iPad, or iPod touch, it’s actually as simple as tapping and holding your finger on the link, instead of quickly tapping and releasing.
A menu will slide up from the bottom with the URL of the link shown right at the top. From here you can also open the linked page in the background (or in a new tab if you’re on an iPad or iPhone 6 Plus in landscape mode), add it to your reading list, or copy it to your clipboard.
