How: Refers to the design, or look, of a source.

Visual layout, stylistic choices, images, and advertising often influence the credibility of a source. This can be especially true of web sources since sites can often contain dynamic animation and other content. 

It's important to ask:

• Are there lots of ads?Are there flashy graphics? Do they add or take away from the source's credibility or legibility?
• What kind of information is presented on the page? 

Additional Internet Source Consideration:

• Is the site easy to navigate? Is the content well organized?
• Are there dead links?
• Is the download time and site navigation slowed down by too many images or media files?
