Make your Blog Scannable
Good blog posts can be scanned with the eyes. In order to make this possible, use bold text to make the important content stick out. Make things like dates, times, and people appear in bold type. When a reader is scanning over the content, this important text helps them decide if the content is worth slowing down for.
Changing colors is discouraged. For some visitors, this can make reading the blog more difficult. Stick to standard ornamentation to text by using boldface and italics to emphasize important points.
If you have a really long blog post, consider using headings to break up sections. You’ll find the tool for adding headings in the Visual (expanded) toolbar in WordPress.
