An interesting sidebar addition to a blog can be a way to make it more interactive and engaging for readers. Sidebars can be used to house blogs’ most popular or frequently visited posts, or to house blogs’ most popular or engaging content.
Should a blog have a sidebar? That answer is subjective and depends on the blog’s content and design. If a blog’s sidebar is well-designed and uses interesting visuals and promo materials, it can help promote the blog and make it more interactive.
However, if a blog’s sidebar feels cluttered or out of place, it may not be as effective at attracting readers and promoting the blog. Ultimately, whether or not to include a sidebar on a blog is up to the blog owner.
