I have a blog with hundreds of quality and unique contents developed since 2008. I have not done anything with it since then. All the contents are dated between Feb 2008 to Nov 2008. I want to start sending traffic and moneytizing the blog now but not sure of the best way to start. Is it ok if I hire someone to change content dates to between December 2009 to today? Any advice on the best way to start this will be appreciated. Thanks all.
