How could you get Google+ comments on your website and from where in the Google+ account do you get the embed code ? By comments I mean comments similar to facebook for websites where people can comment using their account, not share buttons. Not services like disqus. Thank you.
Search for plugins for that if your website is on WordPress. Else, you need to seek some developer's help to embed that comment section on your website.
WordPress gives control over your blogs Great for SEO purpose Much better from blogger in terms of customization and flexibility So my vote goes to WordPress
