This tool can extract your blogger blog’s comment author’s Google profile. The use of this tool is “It can extract the comment authors profile from the Google and show their public details including their public profiles, location and other shared details”. It will help you to analyze your comment author’s location and can easily follow them.
Please note that it will work only if their Google plus profile is public(Normally Google profiles are public) and they used their Google plus profile for commenting(Blogger now started to link Google plus profile to Blogger profile. Instead of Blogger profile, Google plus profile is used if they activated this feature). Give me feedbacks, so I can modify it. Thank you.
Below is an example of extracted profile
