We have a site with about 700 pages. Many of the pages have backlinks. Some pages have lots of backlinks perhaps more than homepage.
We working on a new site. We cannot afford to loose positioning and all that link juice and SEO. Static HTML is safe however, designer is pushing for CMS with HTML extension and directory paths.
The question is can, CMS with these extension be safe and will there be any SEO risks changing to a CMS ?
