8 seconds website test

After numerous researches it was found that when people arrive at a website, at least half of them (i.e. 50%) will leave that website within 8 seconds. This information is publicly available because huge corporations spend a lot of money to know how people use the Internet. They are eager to know people tastes (i.e. what people like and dislike). These corporations have spent millions of dollars on research, so their results can be trusted.
