I have a website of around 100 pages. I'm doing a redesign and adding more content in an attempt to improve se rankings and traffic. All pages of this website are placed in the base directory, although I do have different topics. I'm thinking of better organizing this website, creating several directories for each topic and placing files in these directories. I feel it's better this way plus search engines recommend good design. My question: do you think it's worth it? Doing this implies changing all my file names.
Thanks.
