Taking a look at the URL of a link you are about to open is a good way to make sure the URL is what you expect and not a trick. See how to preview links in Safari for Mac, iPhone and iPad.
How to preview Safari links before opening on Mac
Popular desktop web browsers have had URL status bars for decades. However, Safari for Mac does not enable it by default. If you want to quickly check the URL of a link, you can do so by activating the status bar.
First, open the Safari application on your Mac. Click on the "View" section in the menu bar and select "Show Status Bar".
With this enabled, when you hover your mouse pointer over any link, you will see its full URL in the status bar in the lower left corner of the page.
If you want to turn off this link preview, click View> Hide Status Bar in the menu bar at the top of the screen.
How to preview Safari Links before opening them on iPhone and iPad
Unlike Mac, Safari on iPhone and iPad has no status bar. But it lets you take a look at the page you want to open. You can tap and hold any link to load the page in a preview pop-up. If you do not like the full preview, you can only switch to the URL view (like Safari on a Mac).
To get started, open a Safari page on your iPhone or iPad. Click and hold any link on the page.
If you are using iOS 13, iPadOS 13 or later, you will see a thumbnail preview of the pop-up page. To preview the URL, click the "Hide Preview" button at the top of the pop-up window.
The thumbnail will disappear and you will see the URL mentioned in the box. If it looks safe and you want to open the page from this popup window, click the "Open" button in the menu list below the preview pop-up window.
If you want to return the thumbnail later, just tap and hold a link and select "Tap to show preview" at the top of the pop-up window.
Tracking addresses URL is another way that more knowledgeable browsing will help you avoid scams and keep you safer on the web.
