A blog is an online journal that allows users to share information, pictures, videos, and links. Users can create blog posts that are displayed on pages within their blog. Posts can be saved as drafts before being published publicly. Tags help readers find specific topics. Comments from readers can be moderated by the blog owner. To get a blog noticed, users can add links in emails and newsletters, on their website, and share on social media. The hosting option depends on the blog's intended impact.
