My wife informs me that if we have a wordpress.com blog, WordPress.com gets the traffic and the corresponding benefit of Google ranking. Is that the case? If I have a mapped domain, does that change how Google looks at the site, or does it still credit wordpress.com? The issue is we have a magazine site hosted on another host provider with shared servers. The site has been dog slow and we're about to do a huge Groupon email. I love the stability of WP.com blogs and want to change our blog from the host provider to a wp.com site. The current site is http://teenidentitymag.com (a WP site hosted on Blue Host). I created teenidentitymag.wordpress.com (currently private) but my wife doesn't want to switch b/c of this ranking issue.
What is the definitive answer on this?
The blog I need help with is teenidentitymag.wordpress.com.
