I am going to redesign the website of the company I work at. The website runs on WordPress and currently has a pretty decent ranking. It uses the plugin "The SEO Framework".

What do I have to be aware of to not ruin the rankings with the new Website?

I'm developing the site on my local Server and aftwe switching it to the main domain, I will redirect any URL, that may be changed. The site will mostly use the same content, but better structured and visually improved.

Do I need to pay attention to anything else?

Thanks in advance!
