One of the growing concerns for many webmasters and SEO is how to embed SEO on a site using CMS? Like issues of duplicate content. Any ideas?
search engines do not consider duplicate content on the same domain, only when it's seen across multiple domains. there's nothing to worry about.
What kind of "issues" are you worried about? SEO is quite the big field that you can't expect people to just hand you an essay of all possible topics. People here could rave on about whatever they think applies but you might mean something totally different.
