I own an old website, but very well ranked in Google. My intention is to change the layout of the site, making it more beautiful, clear, clean and modern.
I also want the site to have an easier and intuitive navigation to the user.
I do not like the format the page currently is.
My concern is that I can not lose URLs and my Google ranking.
The person who is responsible for doing this work should introduce me to some options and templates ...
I am totally open to advice and new ideas.
