Scan-ability
Scan-ability refers to the capacity text has to be scanned by readers. Writers of digital media must pay special attention to scan-ability because readers of digital writing are known to be easily distracted, impatient, and unwilling to read huge blocks of text. Scan-ability is crucial for digital writing because, without maintaining a good level of it, readers will not pay attention to your work.
Layering content
To make your blog scannable, layering content is a necessity. Brian Carroll says "layering is a response to the reality, the documented fact that Web users do not read." Layering content involves working with text, the visual qualities of text, multimedia, and linking.
Text
Headlines, subheads, and sub-subheads
Headlines, subheads, and sub-subheads draw the attention of readers to a body of text. Large headlines allow readers to scan the text, and smaller lines like subheads and sub-subheads are actually read by readers.
Teasers exist to encourage readers to read more of your posts. According to David Doolin, "A well-written teaser will provoke a reader’s curiosity to continue reading on your web site." Teasers should be concise in order to work smoothly with the user's tendency to scan. Keep your teaser limited to one sentence.
Brief summary paragraphs
Digital writing needs to be concise to ensure that readers will read the entirety of the text. In addition to making sure you write with the inverted pyramid in mind, you should also stick to one idea per paragraph. Typically, users will move on from a paragraph if they are not impressed by the first few words. Using one idea per paragraph keeps your writing focused and maintains brevity.
