I'm publishing download information about Income Tax every year(during income tax filing period of April-Aug). Now the theory says that  articles old by 2-3 years rank higher in Google's rankings than the similar but recent articles. So in 2010 the page title was Income tax 2010-2011 and it attracted huge trafficIn 2011 the page title was Income tax 2011-2012 and it attracted very less trafficIn 2012 the page title was Income tax 2012-2013 and it attracted very less trafficSo observing this after a month I removed 'Income Tax' from all the pages(3-4) except for this latest page applicable for that year. But no gain till August last year.Now is the time for 2013-2014 Income Tax pages. I'm confused, how I should optimize the Income Tax 2013-2014 page(title+content) so that my pages can get high traffic as in 2010. Given old pages remain intact.Any ideas?
