Web users form first impressions of web pages in as little as 50 milliseconds (1/20th of a second), according to Canadian researchers. In the blink of an eye, web surfers make nearly instantaneous judgments of a web site’s “visual appeal.” Through the “halo effect” first impressions can color subsequent judgments of perceived credibility, usability, and ultimately influence our purchasing decisions. Creating a fast-loading, visually appealing site can help websites succeed.
