Whether we are hungry or not, the first thing we do before we eat is to observe the food. How does the food look? What are the ingredients? Websites are similar to foods. Even a website would be beneficial, if it's not appealing, a user would not spend his/her time on it. In addition to your website design, you should use popups to pull visitors towards your web page.
Annoying ads and imprecisely done popups may affect users negatively. Try to avoid them by working with professionals.
