A coming soon page is a site where visitors are going to land right before they find out about who you are, what you do, and what you are going to offer soon. Show them something intriguing and completely mind-blowing. Impress and leave a trace in the memory — this is the only way to make them come back and actually the key mission of a coming soon page.
A coming soon page is an announcement inviting a web user to come in a bit later, just after you are up with the repairs. However, it should assure that the product is worth waiting and returning.
