Because SEO has become such a holistic part of website development and improvement, it is no surprise that content formatting—the presentation, style, and layout choices you select for your content—is a part of the process. Choosing browser-safe sans serif fonts such as Arial and Helvetica is a wise choice for the Web; Verdana in particular has received high praise from usability/readability experts, such as that WebAIM offered in an article posted at http://webaim.org/techniques/fonts/.
Verdana is one of the most popular of the fonts designed for on-screen viewing. It has a simple, straightforward design, and the characters (or glyphs) are not easily confused. For example, the uppercase I and the lowercase L have unique shapes, unlike in Arial, in which the two glyphs may be easily confused (see Figure 6-23).
