Can we use features as tabbed contents in all pages of website? Will google scan and list as duplicate content or will tabbed content hides? Is it harmful to SEO?
Any kind of duplicate content will be harmful to your website no matter what it is - Google and other search engines will quickly lower it's position in search engines.
How the tabbed content is been created is to be taken care of, if you make the tabs using javascript then google will not be able to read it and thus there will not any problem for you. But if in case css has been used then google will be able to read it and you will have problem as it will be considered as duplicate content.
