The Hammers, who beat Swansea City at Upton Park last weekend, have won only twice on their travels in the league this season.
"I think Saturday has given us a lift," Cole told the club's official website.
"Thirty points is a big barrier to get to and now we're all looking up. The next game is Aston Villa - we want to improve our away form and it's important that we get a result there.
"We need to get some momentum going on the road by getting points on the board."
Cole has scored one goal in five appearances for West Ham during the current campaign.
