How to add links in WordPress blog site into your sidebar ?
You can add links into your sidebar ( left or right column ) or footer area if you enable link widget.
You can modify links add or remove from your list. To do so, go to your dashboard.
To add a new link, click on Add New in the Links menu:
You can give a short name to your link, a description and you can also choose the target of the opening window.
If you select the blank option, then when your visitor click on that link, it will open in a new window, therefore your visitor will not leave your site.
If you do not see links on your sidebar or footer on your blog, you should look at your theme Appearance.
To activate links on your theme, Click on Appearance then Widget. Drag the links widget into your sidebar.
Links Widget displays a list of links (also known as a blogroll) in your sidebar.
