This is a very common question and one that has many opinions. This is no longer the time of “set it and forget it” websites. You can not just create a website an let it rest there for the next 5 years, Why? Just because technology changes, design changes and most importantly people change. Here we are not talking about technical changes, such as updating your WordPress or plugin versions. Here we are referring to content updates. A lot of that depends on your industry. What do you do?
Who are your customers? And what is new that appeals to your customers.
