There may be times when you’ll choose to have your site do some of these user-unfriendly things deliberately. Sometimes it makes business sense not to do exactly what the customer wants. For instance, uninvited pop-ups almost always annoy people to some extent. But if your statistics show you can get 10 percent more revenue by using pop-ups and you think it’s worth annoying your users, you can do it. It’s a business decision. Just be sure you do it in an informed way, rather than inadvertently.
