How to open link in a new tab?
1. Open your banner in Ad Editor, select "Elements" menu
2. Click "Add HTML" button
3. Edit HTML code
Delete the the old HTML code: "<p>Your HTML here</p>"
And replace it with following code (just change google.com to your own link):
<a href="http://www.google.com" target="_blank"
style="width:100%; height:100%; position:fixed;"></a>
4. Save banner
That is it! Now if someone will click on banner, the link you specified in HTML code, will open in a new tab.
