The new year looks ideal time to start anything new especially renovations. You don't remember date for next renovation. Modifications are important in everything. Your website is not any different. Knowledge changes with time. A website copy written a year back may be old now. Customers want to see and grow with you. They continuously want new things. You need to add new knowledge more often. Website copy is something that you can not revise daily or weekly. But before your content turn out too old you need to revise it. Your website is same like a computer. If your machine runs longer you need to restart it and perhaps give a cold boot. Same is with website. Your audience will love to see your website in new shape. Definitely they are used to old patterns but if you can add more value audience will appreciate it.
