Do you make external links open on a new tab?
External links should open in a new tab (by using HTML's target="_blank"). Since browsers implemented tabs (replacing new window), it's considered a good practice to open external links in a different tab.
Main reasons are:
- Avoiding 'Back-Button Fatigue';
- Keeping 'User Flow';
- Keeping a good track of Analytics
