This contact widget comes with microdatas & microformats markup, so that search engines can use it in their search results. They can help display contact information about your business or yourself below your website in search results, and even a map with your location, to improve your local SEO.
The telephone & email are linked so that visitors can click on it and make a call (through mobile or skype) or send a mail from their computer or their mobile devices.
You can also display a static image map of your location, linking to the address’ Google Maps page, and display a download link for a vCard.

This plugin extends the standard WordPress profile to inclue additional 
attributes such as photo, organization, address, phone number, and others. A 
user’s entire profile can then be output as an <a href="http://microformats.org/wiki/hcard" rel="nofollow ugc">hCard</a> on any page using the 
 profile shortcode, or with the provided widget.

Extended Profile

Extend the WordPress profile to include additional attributes, and output as hCard.
