Blogroll is a list of links to your favorite blogs or sites. Usually, but not always, it refers to sites similar to your website’s topics. Blogrolls are usually added in sidebar or footer of a WordPress blog.
Blogroll was a feature in older versions of WordPress that allowed users to display a list of links to other blogs and websites in their sidebar or footer. It was essentially a way to showcase a curated list of recommended resources and connect with other bloggers and websites.
