Using vertical, bulleted lists is a very effective way to make crucial points stand out, because bullet points are easy to scan and understand. Research shows that vertical lists attract a readers’ eye, and that readers of digital content prefer writing that’s formatted for easy scanning, because it allows them to skip through large chunks of text and get to the stuff that interests them.
There are several formatting methods that can achieve the goal of breaking up dense paragraphs of text; there’s bolding, line-spacing, indenting and even color-coding. But I think bulleted lists are the most powerful method to encourage reading content on a digital device.
Web readers typically want to absorb content quickly, and bullets are perceived as “shortcuts” to the concise and important content they’re looking for. In usability studies, readers gravitated towards bulleted lists first.
