According to Forbes, humans develop initial impressions of each other in just seven seconds. Should we approach or avoid that person? Are they trustworthy, competent, likeable? We make all these evaluations at lightning speed. When it comes to a website, our brains work even faster. A study in Behaviour & Information Technology found that it takes .05 seconds for us to form an opinion. So just like meeting someone for the first time, when it comes to your website, you better knock the socks off of people—and you have less than a second to do it!
