You need to change the settings for the links so it opens in a new window and doesn't take the site visitor away from your site. It's hard enough to get them there, don't send them away!
- Click on the link
You'll see a little pop-up with the link, a pencil and an 'X'.
This is the link information.
- On that pop-up, click the pencil / 'Edit' button
This let's you change the link, handy, but not what we want right now.
- Click on the gear / 'Link options' button
Now we're in the nitty-gritty of the link!
- Check the 'Open link in a new tab' box
This will make sure the link opens in a new window.
- Click on 'Update' to save your changes.
Update the page/post and have a look at it. Make sure the link works the way it should.
