Footers can help the appearance of your website greatly. The problem is that the footer is located at the bottom. There is a really slight chance that the visitors scroll all the way down to the end of the page to see this information. According to statistics, the lengthier your page is, the more tired the users become after reading the page and the more willing they will be to leave that page once the content is over. This means most of the time your footer won’t be read by the users at all. This does not mean you shouldn’t put any effort in this part though. Footers are extremely important and if you want people to read it, you need to choose the right designs for it to lure the visitors in. having a shorter page with less distracting feature also helps. In short, try to give the readers a reason to scroll down and see the footer.
