Dears, Recentely I started with Wordpress, but I have an old files that I want to integrate with wordpress, these pages drive me traffic already so I want to ask is such integration could effect my seo badley? It's difficult to keep the pages url and name, wordpress url and extanstions are completely different. So what is the best way to go with this integration without effect my ranking badely??
You may put the content for these pages on wordpress and use a 301 redirect from old pages to new ones. Alternatively you can keep both versions online and use rel=canonical in older versions to tell search engines that they are copies of content lying elsewhere on your site.
