My father had launched a website few years ago. Now, I have taken over the business responsibility. And I have decided to change the outlook of the site. I think the design is very old, and the content needs modification. If I can update the website with the content, can anyone tell me whether my achieved page rank and traffic will drop or not. If not, then what is the process of editing the old website? In case, there are any online guides available, kindly share them with me. I am waiting for your comments. Thank you and regards!
