4thegame.com - the offical web site of the Premiership sponsor, currently Barclaycard - will provide content for the channel and run regular competitions to win match tickets, merchandise and other football-related items.
It will also feature in Freeserve's Barclaycard Premiership Focus section.
The site, previously EPLsoccer.com, is run by content provider Fast Web Media.
Jon Gisby, managing director of portals at Freeserve, said: "Having 4thegame.com on board strengthens our proposition to existing and new users."
