Links Menu (Blogroll)
As bloggers we often link to our friends, our favorite posts, and popular web sites. Links make the Internet what it is. Without them it would be very hard to get from one site to another. WordPress.com gives you many different ways to use links on your blog.
The instructions from this guide are referring to the WP Admin dashboard. You can get to this dashboard by adding /wp-admin to the end of your site’s url (e.g.: example.wordpress.com/wp-admin)
The Links menu in your dashboard can be used to create a blogroll. A blogroll is essentially just a list of links that appears in your sidebar. The term “blogroll” was originally used because it was a list of links to other blogs, but you can include links to any sites.
Adding links to your blogroll doesn’t do anything for your readers unless you display them on your blog. To display them in your sidebar you need to add the Links Widget to your sidebar.
