I always keep up to date with SEO trends on Google by monitoring what Matt Cutts has to say about various SEO topics using the Google search engine. I also listen to what Greg Grothaus has to say as he is a Search Quality Software Engineer who works for Google. I recently studied one of Greg's videos about the myth around duplication of content on Google. I was wondering whether sending the same content to different content submission areas like press release, article, forum and blog companies would be considered duplicate content. These content submission companies all have and create different urls for content submissions compared to creating many domains that have the same domain name but differ slightly with their extensions and or sub domains and then placing the same content on them. Greg Grothaus's video can be viewed at youtube.com/watch?v=6hSoXutuj0g and I ask all serious SEO professionals to comment on and to discuss whether they agree with me or not. Looking forward to your comments.
